Prosto Medical

Prosto Medical is designing a low-cost negative pressure wound therapy technique for surgeries that happen everyday. Traditional negative pressure therapy uses expensive vacuums to remove unwanted fluid from the wound bed. While it has been shown to radically reduce the rate of infection and healing in complex, hard to heal wounds, its prohibitively expensive for smaller wounds. Prosto Medical thinks that the same amazing results can be brought to post-surgical incisions after orthopedic, c-sections and other common surgeries to massively reduce hospital acquired infections. Using simple, cheap concepts and components, we have created The Low Cost Solution for negative pressure wound therapy over surgically created wounds. 


Epixys develops a suite of devices designed to improve the ophthalmic patients’ ability to adhere to a prescribed eye medication regimen. At the core of the Epixys platform is an ergonomic pen-sized device which stores multiple eye medications simultaneously for delivery as an aerosolized mist. The device alerts the patient when it’s time to deliver medication and tracks patient behavior in order to proactively address any care gaps. The result is an end-to-end solution that solves the main drivers of poor ophthalmic medication compliance, with the potential to drastically improve patient outcomes.


Thousands of people every year suffer accidental ureteral injury during pelvic and colorectal surgeries. These errors carry a significant cost for the patient and the broader health system. UroProx aims to dramatically reduce the rate of ureteral injury by employing a proximity sensing system to allow surgeons to more precisely localize and avoid the ureter. The system is composed of a low-cost magnetic intra-ureteral stent that is detected by a Hall-Effect sensor integrated into the tips of laparoscopic tools. The system can be calibrated to give the surgeon multimodal feedback on ureter position at distances of up to 8 cm. We anticipate that the precise, real-time feedback on ureter position given by the UroProx system will provide surgeons with the safeguard they need to avoid accidental ureteral injury.


Our invention is a portable device used to monitor muscle activity for such purposes as physical rehabilitation, athletic performance, and targeted muscle training. The device includes sensors encased in a wearable material that forms to a user’s skin, and transmits accurate data regarding specific muscle activity. The data is then stored, mined and displayed for users in real time. Trac allows users to make comparisons between their healthy arm and an arm in recovery, for example, as well as gives trainers and physical therapists the ability to track progress and tailor exercise regimens.


Vesperia believes that all individuals should enjoy the sports that they love while having their health and futures safeguarded from preventable head injuries. For athletes at risk of traumatic brain injury, our product, One Brain, offers rapid and objective concussion detection at the site and time of impact. Through the use of our multimodal technology, we provide a decisive concussion assessment at the sideline to help protect athletes both in the game and well after play concludes. One Brain. One Test. One Answer.

Thermal Imaging to Detect Surgical Bleeding

Surgical bleeding that is missed intra-operatively can require re-operation and contribute to patient morbidity and mortality and procedural costs.  For cardiac surgery, the re-operation rate due to missed surgical bleeding is estimated to be 2.4%.  Currently, the only method that is widely used to detect bleeding intra-operatively is unaided visual inspection, which is limited by the difficulty in focusing on the whole field at all times and distinguishing fresh new blood from pooled old blood.  Thus, a new technology is needed to detect surgical bleeding that can monitor the whole field in real-time, alert the surgeon to the presence of new blood, and direct the surgeon to the location from which the bleeding originates.  Thermography with real-time image processing and display has the potential to fulfill this need.  If successful during open surgery, this technology could potentially be extended to other such as laparoscopic surgery and endoscopy.


As an obese patient undergoes laparoscopic surgery, the increased size of their abdominal wall severely limits the range of motion of the surgeon's instruments, causing both conversions to open surgery and the introduction of additional laparoscopic ports. These factors contribute to additional complications and additional costs. Quivious has developed an advanced trocar that utilizes a novel compression mechanism to reduce the size of the abdominal wall during surgery, restoring the reach of the laparoscopic surgeon and allowing for safer, more cost effective procedures.
