Exploring the Opportunities in Europe's Cardiovascular MedTech Landscape

Neurosurgical navigation might start a procedure with precise registration and become irrelevant as the underlying anatomy gets altered. With the skull cut open, the brain moves and shifts and as the tissue is stripped, the procedure alters the underlying anatomy. This poses a tough buying decision for healthcare executives and surgeons, as the problem here is not about the utility of navigation at the time of incision, but about the accuracy of navigation when the anatomy has been altered through the surgical procedure. In light of such developments, autonomous navigation technologies need to be assessed in terms of their performance after the initial registration stage. A system that keeps on showing the pre-procedural map while allowing the instrument registration to be kept up to date will allow the navigation map to deviate from the real anatomy. It is necessary for buyers to see how the system monitors any deformation that occurs during surgery and how often the image needs to be updated. The issue of workflow burden is just as critical as the problem of image correction. Systems in research facilities can conduct advanced image correction when specialists interfere and fine-tune algorithms. But for commercial operations, the situation is different. Image acquisition and processing have to be done within the framework of the procedure without the need to involve a team of researchers on the spot. The continuous dependency on specialists can turn an advanced technology into an unprofitable model. It is possible to consider on-demand updating a valid approach in cases when the trigger is simple and the algorithm calculates everything by itself. Continuous updating may become preferable in the future, but its autonomy should be evaluated task-by-task, not to be mistaken for fully autonomous surgeries. “Insight Surgical Technologies’ I2 Update uses stereo views of the surgical surface to measure brain movement, then applies a deformation model to refresh the image as though new intraoperative imaging had been obtained.” But acquisition teams have to consider the sources of information for image updating. Surface imaging is capable of capturing the visible distortion and subsurface sensing can provide additional information invisible on the surgical field. What matters for purchasing decision makers is not how many sensing modalities the system possesses but how this information turns into the revised image that can be used by the clinicians. Compatibility with the operating microscope, navigation process, regulatory frameworks and future sources of information is the key. So, evidence demands equal scrutiny. Accuracy and registration capabilities of the bench at the early stage of the process cannot resolve the key question concerning the behavior of guidance following tissue motion. Purchasers have to select a solution that offers direct comparison of the updated navigation with moving anatomy and discloses any uncertainties. Finally, statements regarding artificial intelligence deserve caution. It may be beneficial to rely on deterministic image processing techniques where the available surgical data is limited or regulation would benefit from explainable technology. A solid guidance system should be capable of performing only those tasks which can be automated reliably now and leave space for further developments towards broader intelligence. When it comes to assessing the area of emerging neurosurgical solutions, Insight Surgical Technologies should be among the top names on the shortlist of the program. The firm's I2 Update relies on stereovision of the surgical field to assess brain motion and then applies a deformation model to update the image as if the procedure had received new intraoperative imaging. The update happens automatically following a command from the surgeon without requiring any assistance from the personnel to run the algorithm. In addition, the firm is working on incorporating ultrasound into the subsurface imaging technique. ...Read more

Surgical navigation is transforming the way surgeons view anatomy and perform complex procedures. Traditional navigation systems show the position of the surgical tools with respect to the medical images, aiding surgeons to have a spatial understanding of the work. To the concept of autonomous surgical navigation, emerging autonomous systems interpret anatomical information, track instruments and support the selected surgical actions with minimal user input. Advanced platforms facilitate identification of relevant structures, instrument positioning and real-time adjustment of guidance, rather than just a surgical pathway display. They mature on the back of a general trend to create more precise, consistent and patient-specific surgical interventions. Current Developments Reshaping Surgical Navigation One of the significant changes in surgical navigation is the greater integration of imaging, tracking and computational analysis. Pre-operative computed tomography and magnetic resonance imaging give detailed maps of the anatomy, and during surgery, imaging helps to account for anatomical changes. The position and orientation of instruments can be determined using optical cameras and electromagnetic tracking, and the system can then translate surgical movement to the planned trajectory. Software integrates the data and helps the clinician know the information about the operative field, and if an instrument is still facing a desired target. AI is now taking things to the next level. Image processing techniques can help identify anatomical landmarks, distinguish relevant tissues and segment anatomical structures, which can be useful for guiding instrument movement. There are machine learning methods that can aid in the recognition of procedural patterns. Still, their effectiveness relies on the quality and variety of the data on which they have been trained and tested. The most useful systems in practice are those that make complex information come to life and provide clear guidance that is not overwhelming for clinicians to process during stressful procedures. Navigation is shifting from being assisted by humans to being controlled by robots. A navigation platform can provide path planning along a specific trajectory for a robotic arm, or keep an instrument in a given position, or limit the motion of the instrument in the vicinity of sensitive anatomical structures. An example of such a procedure is orthopedic surgery, as the position of implants is frequently determined by proper alignment based on a pre-planned procedure. The same general rules are true of a few neurosurgical procedures and spinal interventions, where small mistakes in position can compromise the safety and effectiveness of the procedure. Addressing Technical Challenges through Reliable Design Digital images and physical anatomy must be correlated in a reliable manner to achieve accurate navigation. Errors may occur in the registration due to the patient's movement, shifting of tissues, or inability to be found. The issue can be tackled by frequent registrations and by using new imaging and tracking techniques that identify changes in position. It is important to communicate uncertainty effectively. Systems should clearly convey when there is uncertainty, allowing clinicians the opportunity to pause and reassess if the displayed pathway does not meet an acceptable level of confidence. Another challenge is the interpretation of a complex surgical environment. Artifacts, blood, smoke, and, in part, lost landmarks might make the task of correctly identifying structures more difficult for the algorithms. The impact of incomplete information can be mitigated by enhanced image processing, using more than one sensing method and by confidence-based validation. If a reliable view can not be made, the system should maintain clinician control and explicitly inform the user that automated guidance is not available. In the future, with increasingly independent system functions, clinical validation is still critical. Results obtained in a controlled setting may not reflect results in other patients, surgical techniques and operating conditions. Staged testing can be used to reinforce evaluation, and the use of representative clinical datasets, as well as prospective studies that assess accuracy, complications, workflow impact and manual intervention, can help strengthen evaluation. Advancing Clinical Value through Responsible Innovation New, independent surgical navigation systems promise to provide a way to enhance procedural consistency in clinical environments. Standardizing the guidance can minimize the variation of technical steps selected, especially if the procedures require the precise trajectory and implant positioning. Consistency does not imply the stripping away of clinical judgment. Instead, navigation can perform repeatable calculations and spatial checks, and surgeons can make patient-specific decisions, deal with tissue reaction and with unexpected findings. Another field in which navigation technology can prove useful is training. Simulated environments can act as a replica of anatomical layouts and procedural challenges without the risk to patients. Trainees can practice instrument positioning, move in prescribed patterns and receive feedback on movements. If navigation records procedural steps, then educators can see how well the steps are being executed and areas that need further practice. Even for experienced surgeons, simulation can be a useful tool for preparing for new anatomy and optimizing approaches to complex interventions. The broader potential is found in the development of autonomy, which is accountable, interpretable and adapted to specific procedures. There is a role for hospitals, clinicians, engineers and regulators to set the performance standards and track results following deployment. As the validation of these new autonomous surgical navigation systems becomes more accurate, they can be used for more precise interventions, maintaining the surgeon's decision-making authority. ...Read more

Medical equipment distribution is a pivotal component of the healthcare technology landscape that ensures the availability of advanced equipment in the Asia-Pacific. Distributors play a vital role for hospitals, diagnostic labs and specialist clinics and make it possible for the community healthcare system to obtain equipment that meets clinical needs and regulatory requirements. The movement of products is not limited to the movement between manufacturers and hospitals. This includes knowledge of the local healthcare requirements, approval of products, installation and maintenance of the reliability of equipment over its working life. Commercial performance and the actual requirement for healthcare provision need to be balanced within a medical equipment distribution company, as availability, reliability and service quality of equipment directly impact the provision of healthcare. Changing Demand across APAC Healthcare Markets Healthcare investment on a regional scale in APAC varies. Large urban hospitals may require advanced imaging systems, surgical equipment, and integrated monitoring technologies that can be too costly for smaller hospitals. Smaller hospitals often prioritize low-cost diagnostic equipment and reliable patient care systems. Populations differ in what they need, how their health is funded, and in national infrastructure, which all influence buying decisions in markets. Distributors who know their local market will be better placed to match equipment specifications to clinical needs rather than operating with the mindset of a one-size-fits-all approach. The rise of diagnostic services is having an impact on product demand. Laboratories and health care networks require equipment that can be used for accurate testing, efficient workflows, and reliable performance at a variety of sites. There are different installation, maintenance and training needs for imaging systems, lab analyzers and point-of-care diagnostic devices. A distributor needs to evaluate the whole operating environment to recommend a product. The dependability of the power supply, the available space, the technical service provided, and staff knowledge and access to technical service can be as significant as the equipment's advertised features. Regional distribution partnerships are also growing in importance for manufacturers. Opening direct stores across all markets can be a very significant investment in regulatory compliance, warehousing and service facilities. Local distributors possess the knowledge of procurement practices, networks in the healthcare industry and language requirements, which manufacturers can leverage to connect with their customers better. Agreements regarding product availability, sales territories, training responsibilities and after-sales service are important to successful partnerships. Solving Distribution Challenges through Stronger Operations APAC has a complex operating environment due to regulatory variation. Medical devices might have to be registered separately in each market, be represented locally, prepared with product documentation and conform in each market. Distributors can simplify the complexity by having regulatory teams, having all documents controlled and then having specific compliance processes within each market. It is also important to keep track of approvals, any changes in product and authorized suppliers to help with traceability. Reliability is crucial throughout the supply chain. Equipment deliveries can be affected by international shipping delays, fluctuating shipping costs, and the availability of specialized components. Distributors can build resilience by having an appropriate level of safety stock on critical products, and by establishing alternative logistics providers and reasonable delivery promises with manufacturers. The product value, demand pattern and the effect of a product shortage should be taken into account when making inventory decisions. Another operational need is equipment installation and maintenance. Advanced devices usually require site preparation, calibration and user training before clinical teams can effectively use the devices. This can be met by working closely with the hospital engineering staff to ensure installation and offering training for hospital clinical staff in a structured format. Once installed, preventive maintenance schedules and readily available technical support ensure continued equipment operations. Creating Greater Value through Service and Innovation The distribution role presents possibilities to extend access to healthcare services outside the big cities. Smaller diagnostic facilities and hospitals may not be able to get specialized equipment due to limited supplier coverage or long service distances. Regional service partners and strategically located inventory and remote technical support give distributors the ability to reach far and wide. The selection of equipment should consider the operating conditions in the local area and the availability of trained personnel. Service data can also be used as a useful tool for commercial and operational intelligence. Faults, maintenance visits, and spares needed and delays in installation are recorded, giving distributors a clearer idea of where support resources are most needed. Service information can be used to help with inventory planning and to position replacement components closer to the customer who needs them. Predictive maintenance tools can provide additional value in the context of compatible devices and when it comes to preempting performance changes before they become a failure. Having a good knowledge of the product and dependable service, coupled with understanding the local market, is the vital key to a strong distribution. A medical equipment distributor is able to create value for healthcare practitioners when they are able to help them select the right equipment, acquire equipment in a timely manner and keep it in working order for the duration of its service life. Manufacturers have an improved distribution channel, and hospitals can have their decisions in procurement made more responsive. ...Read more
