Prosthesis for repairing heart wall defects

Abstract

Abstract The prosthesis consists of a circular component made from a supple material with a shape memory effect, able to occupy three different positions. In the first position (2) it is extended lengthwise to form a small cylinder which can be introduced through a catheter, with its proximal end closed by a valve (4). In a second position the two compartments (8,10) are inflated separately so that they are deployed on opposite sides of the ruptured wall, while in the third position the compartments are squeezed together to form a double patch on the wall. The prosthesis has a radio-opaque marker (6) between the two compartments which allows its progress through the patient's body to be monitored.
