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.

Abstract: A foldable retractor is provided. The retractor includes an arcuate deformable frame that is defined from a first arm extending through a first portion of an outer circumference of the frame, and a second arm that defines a remaining portion of the outer circumference. The first and second arms each include opposite first and second end portions, wherein the respective first end portions and the respective second end portions are hingedly connected together. The first and second arms of the frame are biased toward a first configuration wherein the combined first and second arms are aligned substantially continuously through the combined first and second end portions and the frame extends through substantially a single plane.
