Delivery system, method, and anchor for medical implant placement
First Claim
1. An anchor for a medical implant, the anchor having a deployed configuration wherein the anchor comprises:
- a base member having an axis and first and second ends in oppositely-disposed first and second directions, respectively, along the axis of the base member;
a plurality of arms radially projecting from the first end of the base member, each arm having a first portion extending in the first direction from the first end of the base member and a second portion extending in the second direction from the first portion thereof; and
a plurality of legs radially projecting from the second end of the base member, each leg having a first portion extending in the second direction from the second end of the base member and a second portion extending in the first direction from the first portion thereof;
means for securing the medical implant to the base member so that at least a portion of the implant is between the first and second ends of the base member; and
means for connecting the anchor to a connector;
wherein the arms and legs terminate at extremities that are opposing but not aligned with each other.

Abstract
An anchor for a medical implant, a method of manufacturing an anchor, and a delivery system and method for delivering a medical implant, such as for monitoring physiological parameters, for example, for diagnosing and/or monitoring and/or treating cardiovascular diseases, such as CHF and CHD. The anchor includes a base member, arms, legs, features for securing the medical implant to the base member, and features for connecting the anchor to a connector. The anchor has a deployed configuration in which the arms radially project from a first end of the base member and the legs radially project from an opposite end of the base member. When deployed, the arms and legs terminate at extremities that are opposing but not aligned with each other.

24. A delivery system for a medical implant, the delivery system comprising:
-
a catheter assembly comprising a catheter; an anchor comprising a base member having first and second ends in oppositely-disposed first and second directions, arms and legs extending from the first and second ends, respectively, of the base member, and means for securing the medical implant to the base member; and means for connecting the anchor to the catheter, the connecting means comprising a joint that enables articulating movement of the anchor relative to the catheter in directions transverse to an axis of the catheter. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. A method of delivering a medical implant, the method comprising the steps of:
-
coupling an anchor to an end of a catheter and securing the medical implant to the anchor, the anchor having an axis that is coaxial with the catheter; passing the catheter with the anchor coupled thereto through a sheath; placing an end of the sheath through an internal wall of a human body by moving the sheath in a first direction; with the anchor positioned within the sheath within the internal wall, moving the sheath in a second direction opposite the first direction to release a plurality of arms from the anchor that engage a distal surface of the internal wall; and further moving the sheath in the second direction to release a plurality of legs from the anchor that engage a proximal surface of the internal wall. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56)
