About The Customer
Medtronic is one of the world’s premier medical technology and services companies, known for its leadership in both RF and microwave ablation technologies. The company focuses on delivering procedural solutions that alleviate pain, restore health, and extend life. With a dedicated team of around 40 staff members in the Early Technologies unit of Medtronic’s Minimally Invasive Therapies Group (MITG), the company is committed to advancing ablation technology. Medtronic's mission is to provide innovative medical solutions that improve patient outcomes and enhance the effectiveness of medical procedures. The company leverages advanced technologies and simulation software to develop new ablation probes and optimize their performance.
The Challenge
Physicians rate predictability as their number one concern with ablation performance. The higher the level of predictability, the easier it is for a physician to plan a treatment procedure that will be safer, more effective, and less time-consuming. RF ablation procedures face challenges due to varying electrical conductivities of tissues and the rapid decrease in electrical conductivity as tissue temperature approaches 100°C. This makes it difficult to generate temperatures high enough to cause cell breakdown. MW ablation technology attempts to overcome these limitations by using an EM field radiated into the tissue. However, tissue type and vaporization of water during ablation cause the size and shape of the EM field to vary, affecting predictability.
The Solution
Medtronic’s latest innovation, the Emprint™ ablation system with Thermosphere™ technology, offers more predictable and repeatable results than other techniques and devices. Thermosphere™ technology enables precise control of an EM field independent of the surrounding tissue environment, allowing clinicians to accurately predict the boundaries and characteristics of the ablation zone. The team is using COMSOL Multiphysics® software to develop new ablation probes to achieve even higher levels of predictable performance and effectiveness. One development-stage project aims to optimize the design of these probes to create a more precise ablation zone and provide real-time feedback using radiometers. Radiometers measure EM radiation and enable the characterization of the spatial distribution of an EM field, giving clinicians real-time feedback about the ablation zone. This allows fine-tuning of the zone during the procedure, ensuring targeted tissue destruction while minimizing effects on surrounding healthy tissue.

Hospital Inventory Management
The hospital supply chain team is responsible for ensuring that the right medical supplies are readily available to clinicians when and where needed, and to do so in the most efficient manner possible. However, many of the systems and processes in use at the cancer center for supply chain management were not best suited to support these goals. Barcoding technology, a commonly used method for inventory management of medical supplies, is labor intensive, time consuming, does not provide real-time visibility into inventory levels and can be prone to error. Consequently, the lack of accurate and real-time visibility into inventory levels across multiple supply rooms in multiple hospital facilities creates additional inefficiency in the system causing over-ordering, hoarding, and wasted supplies. Other sources of waste and cost were also identified as candidates for improvement. Existing systems and processes did not provide adequate security for high-cost inventory within the hospital, which was another driver of cost. A lack of visibility into expiration dates for supplies resulted in supplies being wasted due to past expiry dates. Storage of supplies was also a key consideration given the location of the cancer center’s facilities in a dense urban setting, where space is always at a premium. In order to address the challenges outlined above, the hospital sought a solution that would provide real-time inventory information with high levels of accuracy, reduce the level of manual effort required and enable data driven decision making to ensure that the right supplies were readily available to clinicians in the right location at the right time.

Driving Digital Transformations for Vitro Diagnostic Medical Devices
Diagnostic devices play a vital role in helping to improve healthcare delivery. In fact, an estimated 60 percent of the world’s medical decisions are made with support from in vitrodiagnostics (IVD) solutions, such as those provided by Roche Diagnostics, an industry leader. As the demand for medical diagnostic services grows rapidly in hospitals and clinics across China, so does the market for IVD solutions. In addition, the typically high cost of these diagnostic devices means that comprehensive post-sales services are needed. Wanteed to improve three portions of thr IVD:1. Remotely monitor and manage IVD devices as fixed assets.2. Optimizing device availability with predictive maintenance.3. Recommending the best IVD solution for a customer’s needs.

Harnessing real-time data to give a holistic picture of patient health
Every day, vast quantities of data are collected about patients as they pass through health service organizations—from operational data such as treatment history and medications to physiological data captured by medical devices. The insights hidden within this treasure trove of data can be used to support more personalized treatments, more accurate diagnosis and more advanced preparative care. But since the information is generated faster than most organizations can consume it, unlocking the power of this big data can be a struggle. This type of predictive approach not only improves patient care—it also helps to reduce costs, because in the healthcare industry, prevention is almost always more cost-effective than treatment. However, collecting, analyzing and presenting these data-streams in a way that clinicians can easily understand can pose a significant technical challenge.
