1. A medical implant, comprising:
- an anchor portion comprising a first plurality of arms adapted to engage a face of an atrial septum of a body and a second plurality of arms adapted to engage an opposing face of the atrial septum, wherein the anchor portion is configured such that at least one of the arms of the first plurality does not have an entirely overlapping arm in the second plurality on the opposing face of the atrial septum, and wherein the anchor portion does not penetrate the atrial septum; and
an opening portion adapted to define an opening for blood flow through the atrial septum, when the anchor portion engages the atrial septum.

22. A medical implant, comprising:
-
an anchor portion adapted to attach to an atrial septum of a body without penetrating the atrial septum, the anchor portion comprising a plurality of arms adapted to be located on opposite sides of the attachment to the atrial septum by including parts adapted to be located on opposite sides of the atrial septum; and an opening portion adapted to define an opening for blood flow when deployed within the body, which opening has a length of less than 3 millimeters, in which blood passing through the opening comes in contact with the implant. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
