Anchor for medical implant placement and method of manufacture
First Claim
1. An anchor for a medical implant, the anchor comprising:
- a central body comprising an annular-shaped body and having an axis, a bore for receiving the medical implant, and first and second ends in oppositely-disposed first and second axial directions, respectively, along the axis of the central body, the bore having an opening at the first end of the central body for receiving the medical implant in the second axial direction;
means for retaining the medical implant within the bore of the central body;
a plurality of arms and a plurality of members extending from the central body;
a first ring spaced axially from the annular-shaped body in the second axial direction, the members extending radially from the first ring;
a second ring between the first ring and the annular-shaped body; and
struts securing the second ring to the annular-shaped body, the medical implant being disposable within the annular-shaped body and the struts and securable therein by the retaining means;
the anchor having a deployed configuration wherein;
the arms extend substantially radially from the first end of the central body, each of the arms having a distal portion extending in the second axial direction relative to the central body; and
the members extend radially from the central body, each of the members defining a leg extending in the first axial direction toward the distal portions of the arms.

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.

32. An anchor for a cardiovascular implant, the anchor comprising:
-
a central body in which the cardiovascular implant is received, the central body having an axis and first and second ends in oppositely-disposed first and second axial directions, respectively, along the axis of the central body; a plurality of arcuate arms extending from the first end of the central body; a first ring spaced axially from the second end of the central body; a plurality of arcuate members extending from the first ring toward the central body; a second ring spaced axially from the second end of the central body and located between the central body and the first ring; and means for securing the second ring to the central body; wherein the cardiovascular implant is disposed within the central body and the securing means so that an axial end thereof axially abuts the second ring, and the anchor has a deployed configuration wherein the arcuate arms extend substantially radially from the first end of the central body, each of the arcuate arms has a distal portion extending in the second axial direction relative to the central body, the arcuate members extend radially from the second end of the central body, and each of the arcuate members defines a leg extending in the first axial direction toward the distal portions of tile arcuate arms. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)
