METHOD AND APPARATUS FOR CLOSING OFF A PORTION OF A HEART VENTRICLE

摘要

Apparatus and methods to reduce ventricular volume are disclosed. The device takes the form of a transventricular anchor, which presses a portion of the ventricular wall inward, thereby reducing the available volume of the ventricle. The anchor is deployed using a curved introducer that may be inserted into one ventricle, through the septum and into the opposite ventricle. Barbs or protrusions along the anchor body combined with a mechanical stop and a sealing member hold the device in place once deployed.

主权项

1. A method of performing ventricular reconstruction of a heart, the method comprising:
passing a needle from outside the heart through a wall of the heart; passing the needle through a septum of the heart; inserting an anchor through the wall and through the septum of the heart, the anchor being coupled with a distal end of a tension member that extends from the anchor through the wall and septum of the heart; placing a sealing member over the tension member, the sealing member being unconnected from the anchor and being slidable distally along the tension member toward the anchor, wherein an interaction between the sealing member and the tension member resists movement of the sealing member along the tension member away from the anchor; tensioning the tension member to engage the wall and the septum; and securing the wall and septum in the engaged position via the interaction between the sealing member and the tension member.
