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.
Claims8
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.
