1. An implantable device, comprising:
- a proximal anchor comprising a proximal ring, a distal ring, and at least one helical leg extending from the proximal ring and the 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.

33. A system for diagnosing and/or treating a condition in a patient, the system comprising:
-
an implant configured to be implanted within a patient; a proximal anchor comprising at least one helical leg configured to expand from a compressed state to a relaxed state, the at least one helical leg comprising a proximal base and a distal end; a distal anchor comprising at least one distal leg configured to expand from a compressed state to an expanded state; wherein the proximal anchor and the distal anchor are configured to sandwich an atrial septum wall between the distal end of the at least one helical leg and the at least one distal anchor leg and to support the implant in the septum wall; and a delivery catheter configured to deploy the implant, the proximal anchor, and the distal anchor in the septum wall. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63)
