Mechanism for releasably engaging an implantable medical device for implantation
First Claim
Patent Images
1. A method for removing an implantable medical device from an implantation site, the method comprising:
- releasably engaging the implantable medical device at an implantation site by inserting jaw members of a retrieval apparatus through an aperture in the implantable medical device such that the jaw members engage an inner surface of the aperture, wherein the jaw members extend distally from an elongate, tubular body of the retrieval apparatus;
coupling the retrieval apparatus to the implantable medical device by advancing an actuating member through the body and positioning a distal end portion of the actuating member at a location proximate distal tip portions of the jaw members to prevent inward deflection of the jaw members; and
retracting the body such that the retrieval apparatus and the engaged implantable medical device are removed from the implantation site.

Abstract
An apparatus for releasably engaging an implantable medical device during delivery includes an elongate, tubular body having an open distal end a plurality of deflectable jaw members extending distally from the distal end of the body and terminating in distal tip portions, and an actuating member slidably disposed within the body and including a distal end portion operable to prevent inward deflection of the jaw members when positioned proximate the distal tip portions. The jaw members are adapted to releasably engage an engagement feature of the implantable medical device.

13. A method for delivering or relocating an implantable medical device including an aperture, the method comprising:
-
releasably engaging the implantable medical device by inserting jaw members of a retaining element through the aperture in the implantable medical device such that the jaw members engage an inner surface of the aperture, the jaw members extending distally from an elongate, tubular body of the retaining element; advancing an actuating member through the body and positioning a distal end portion of the actuating member at a location proximate the distal tip portions of the jaw members to prevent inward deflection of the jaw members; positioning the implantable medical device as desired, retracting the actuating member to a location proximal to the jaw members; and retracting the body relative to the implantable medical device to retract the jaw members from the aperture. - View Dependent Claims (14)
