Method and anchor for medical implant placement, and method of anchor manufacture
First Claim
1. A method of placing a medical implant, the method comprising the steps of:
- inserting a medical implant (12) through an opening (17) in a body portion (16) of an anchor (10) from which a set of arms (22) extend;
coupling at least a first guidewire (40) to a first portion (32) of the anchor (10) and coupling at least a second guidewire (42) to a second portion (34) of the anchor that is disposed between the body and first portions (16,32) of the anchor (10), the anchor having an axis that is coaxial with the first and second guidewires;
placing an end of a delivery catheter (44) through an internal wall of a human body;
inserting the anchor in the delivery catheter with the first and second guidewires so as to place the anchor within the internal wall, cause the arms (22) of the anchor to protrude in a first direction from the end of the delivery catheter, and then cause the arms (22) to extend substantially radially from the anchor;
retracting the first and second guidewires through the delivery catheter in a second direction opposite the first direction, the first and second guidewires being retracted so that the arms (22) of the anchor contact a first side of the internal wall;
retracting the delivery catheter to release a plurality of members (24) coupled to the first portion (32) of the anchor (10), wherein releasing the members (24) causes the members (24) to extend substantially radially from the anchor (10), causes a leg (28) of each of the members (24) to move in the first direction into contact with an oppositely-disposed second side of the internal wall so as to secure the anchor and the medical implant received therein to the internal wall, and causes the first portion (32) of the anchor with the first guidewire (40) coupled thereto to travel toward the second portion (34) of the anchor;
decoupling the first guidewire (40) from the first portion (32) of the anchor; and
thendecoupling the second guidewire (42) from the second portion (34) of the anchor.

Abstract
An anchor and procedure for placing a medical implant, such as for monitoring physiological parameters. The anchor includes a central body in which a medical implant can be received. Arms and members extend radially from first and second ends, respectively, of the central body. Each member defines a leg extending toward distal portions of the arms to provide a clamping action. The anchor and its implant are placed by coupling first and second guidewires to first and second portions of the anchor, placing an end of a delivery catheter in a wall where implantation is desired, inserting the anchor in the catheter with the guidewires to locate the anchor within the wall, deploying the arms of the anchor at one side of the wall followed by deployment of the members at the opposite side of the wall, and thereafter decoupling the guidewires from the anchor.
