Cardiovascular anchoring device and method of deploying same
First Claim
1. An implantable device, comprising:
- a proximal anchor having at least one helical leg extending between a proximal ring and a distal ring;
a distal anchor having at least one leg; and
an implant configured to be supported by the proximal and distal anchors, wherein the proximal and distal anchors are configured to be movable between a collapsed delivery position and an expanded position in which the proximal and distal anchors secure the implant to a wall of an organ within a patient.

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.
