Abstract
A system for retrieving an implantable medical device includes a delivery sheath that houses an inflatable balloon catheter and a retrieval device. The retrieval device includes a first support rod and a second support rod and a helix extending between distal ends of the first support rod and the second support rod. The inflatable balloon catheter is translatable into a position between the implantable medical device and a wall of a patient blood vessel. The balloon is inflated to force the device away from the wall. The helical member of the retrieval device is expanded radially be translating the second support rod distally. The helical member is moved over the balloon catheter and the medical device, where rotation of the first support rod will cause the helical member to radially compress to trap the balloon catheter and medical device therein for subsequent retrieval from the body.
