TAVI Smart Inflation Programmed Material and Process Properties

Abstract: in some embodiments, a method includes providing a prosthetic heart valve including a collapsible and expandable stent having struts and a valve assembly coupled to the stent, the valve assembly having a plurality of leaflets and a cuff, providing a delivery device including a catheter extending between a proximal end and a distal end, an inflatable balloon, a handle coupled to the catheter, and a memory for storing data disposed within the handle, recording at least one of part-to-part noise factors and process variation factors and storing it in the memory, calculating an adjusted inflation parameter based on the at least one of part-to-part noise factor and process variation factor, advancing the delivery device to a native aortic valve of a patient while the prosthetic heart valve is disposed about the inflatable balloon, and inflating the balloon according to the adjusted inflation parameter.
