Retrieval devices for anchored cardiovascular sensors
First Claim
1. A retrieval device configured to retrieve a cardiac anchoring device from a position deployed in a wall of an organ within a patient, the retrieval device comprising:
- a retrieval head comprising a proximal end region, a distal end, and a plurality of grasping hooks extending from the distal end;
a ribbon attached to the proximal end region of the retrieval head, wherein the ribbon is configured to extend from a retrieval location within a patient to a location outside of the patient; and
wherein the grasping hooks are configured to engage a proximal ring of a proximal anchor, wherein the retrieval head further comprises a distal ring near the distal end, a proximal retrieval head ring, and a plurality of helical legs extending between the proximal retrieval head ring and the distal ring, and wherein the grasping hooks extend distally from the distal ring.

Abstract
An anchoring device and a delivery method thereof can effectively provide a means for securing an implant to a wall of an internal organ within a patient in a variety of clinical applications. In one embodiment, an anchoring device used to retain a cardiac pressure measurement device is provided. The device is implanted in the body by deforming it to a small cross section profile, sliding it through a low profile delivery device and ejecting from the delivery device at a targeted site. The anchoring mechanism, when ejected from the delivery device, reverts back to pre-formed configuration and engages opposite sides of an organ wall, thereby anchoring the implant in the organ wall.
