Current methods for joining peripheral vessels involves expensive microscopes, takes 30-60 minutes per attachment thus increasing the cost and risk to the patient, results in a poor outcome 10% of the time, requires additional training and expertise of the performing surgeons.
Microsurgical Innovations (MSI) has developed a Vascular Coupling Device (VCD) that works for both arteries and veins. It can rapidly connect the two vessel ends together in a watertight seal without leaving any foreign material in the lumen to come in contact with flowing blood. Currently there are no devices available for automated arterial anastomosis and the currently available venous anastomosis device does not work well with arteries. Our device has similarities to the currently available venous anastomosis device; however, it does not have any metallic parts, will be supplied in non-biodegradable and biodegradable versions, can be used easily and more rapidly for both arteries and veins. Our approach will reduce the time required in the surgery suite, reduce costs associated with surgery, and reduce the likelihood of failure of the anastomosis by minimizing human error and stenting open the vessel. We have manufactured prototype devices using non-biodegradable PEEK and HDPE, biodegradable poly(lactic acid-co-caprolactone (PLACL (95% PLA and 5% caprolactone)) in multiple sizes to accommodate varying vessel size in a range of vascular repair scenarios and have performed a number of animal surgeries in addition to numerous leakage and tensile bench-top tests using cadaver vessels.
