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 portion having a longitudinal axis and comprising first and second longitudinal ends in oppositely-disposed first and second longitudinal directions, respectively, of the anchor, and a cage between the first and second longitudinal ends;
a coupler portion connected to and spaced apart from the second longitudinal end of the base portion in the second longitudinal direction of the anchor;
a plurality of flexible arms radially projecting away from the first longitudinal end of the base portion and axially projecting toward the second longitudinal end of the base portion, each arm having a span portion terminating in a distal portion of the arm, the distal portion having a semispherical shape that defines a convex surface facing the second longitudinal direction; and
a plurality of flexible legs connected to the coupler portion and to the second longitudinal end of the base portion, each leg projecting radially away from the longitudinal axis of the anchor and axially projecting toward the first longitudinal end of the base portion, each leg having a first span portion adjoining the second longitudinal end of the base portion, a second span portion adjoining the coupler portion, and an intermediate portion therebetween, the intermediate portion having a semispherical shape that defines a convex surface facing the first longitudinal direction; and
means for securing the medical implant within the cage of the base portion so that at least a portion of the implant is between the first and second longitudinal ends of the base portion.

Abstract
An anchor for a medical implant, methods of manufacturing the anchor, and procedures for placing a medical implant, such as for diagnosing, monitoring and/or treating cardiovascular diseases. The anchor has a base portion with first and second longitudinal ends and a cage therebetween. The anchor further has flexible arms, flexible legs, features for securing the medical implant within the cage of the base portion, and a coupler portion connected to and spaced apart from the second longitudinal end of the base portion. The anchor is adapted to have a deployed configuration in which the arms and legs radially project away from the base portion, the arms axially project toward the second longitudinal end of the base portion, and the legs axially project toward the first longitudinal end of the base portion. Convex surfaces of the arms and legs are adapted to clamp the anchor to a wall.
