Project Overview

Transcatheter aortic valve implantation is rapidly become a mainstay treatment of Aortic valve stenosis especially in patients who are too high risk for a surgical procedure.

Several prosthetic valves are available for such procedure.

One of the challenges faced by operators performing this procedure is the short time window within which the balloon delivery system must be inflated to position the valve.

Often times the heart needs to be paced at very high rates to reduce its output so that the out flow from the ventricle does not displace the valve away from desired position.

The aim is to develop a fenestrated balloon delivery system which allows blood flow through the aortic valve while fully expanded.

Such balloon deployment system will eliminate the need for pacing the heart and is expected to increase the time window within which the operator must deploy the prosthetic aortic valve.
