摘要:
A leadless pulse generator is disclosed herein. The leadless pulse generator has a body, a helical anchor, an electrode, and a sleeve. The body includes a distal end and a proximal end opposite the distal end. The helical anchor distally extends from the distal end. The electrode is at the distal end. The sleeve distally extends from the distal end and has a proximal face and a distal face opposite the proximal face. The proximal face is adjacent the body. The sleeve coaxially extends about the helical anchor and further has a biased state wherein the distal face is near a distal tip of the helical anchor. The sleeve is configured to compress such that the distal face displaces proximally towards the proximal face upon the distal face being forced against the cardiac tissue in the course of the helical anchor screwing into the cardiac tissue.
