Market Opportunities
Heart disease is the leading cause of death in the United States. Heartdisease can often lead to heart failure, which affects about 5.7 million peoplein the United States. When a heart transplant is not an option, which occursfrequently, a left ventricular assist device is used. Left ventricular assistdevices are attached via a graft from the device to a major artery. End-to-sideanastomosis is the surgical connection of this tubular graft end to the side ofa blood vessel that allows for the flow of blood between the graft and thevessel. Currently, the graft is attached via a suture hand sewn by the surgeon.This not only requires a lengthy procedure through large surgical openings in the patient, but also a skilledand experienced surgeon. Complications resulting from this include bloodclotting and dead vessel tissue. A clear need for a less invasive, lower riskprocedure is present. This technology addresses these issues by eliminating theneed for sutures in order to attach the graft to the blood vessel. This mayfacilitate quicker graft attachment and make minimally invasive options nowplausible.
Technology
Left ventricular assist devices are used in order to assist the heart topump blood through the cardiovascular system. This technology improves uponexisting technologies in that it may not require any sutures in order to beimplemented. Researchers at the University of Louisville have developed thistechnology in order to be minimally invasive and easily adaptable. A surgicaladhesive adheres the system together. In research, it was demonstrated that thenon-suture technology may provide secure attachment withstanding physiologicalblood pressures and flows with comparable leak rates
with the hand sewn suture approach.Technology Status
