SYSTEM FOR DEPLOYING A CAPACITIVE SHAPE MEMORY CATHETERIZATION DEVICE AND METHODS FOR USE THEREWITH

摘要

A system for deploying a shape memory catheterization device within a patient, includes a catheter for endovascular insertion of the shape memory catheterization device. A heat source heats the shape memory catheterization device above the transition temperature. A transformation data generator includes a circuit driver for driving a circuit that includes at least one capacitive element of the shape memory catheterization device and a detection circuit for generating transformation data based on a capacitance of the at least one capacitive element, wherein the transformation data indicates a shape transformation of the shape memory catheterization device from a catheterization shape to a transformed shape.
