Patent ID: 8721707

Claim:
A first tubular percutaneous intra-luminal device having a luminal surface defining an interior comprising: a collapsible diamond shaped cell having a pair of opposing side arms that span a distance between a first end and a second end of the cell, said cell having a collapsed state and an expanded state, wherein in said collapsed state said opposing side arms are generally straight and disposed generally parallel to each other and wherein in said expanded state said opposing side arms are bent and extend generally laterally away from one another due to diamond foreshortening, thus forming the diamond shape of the cell; and a centrally disposed strut extending between the first end and the second end of the cell, the strut being configured to deform out of the plane of the luminal surface of the first percutaneous intra-luminal device in a radially inward direction to form a protrusion when the cell is expanded due to diamond foreshortening, the protrusion configured to be mateable with a second frame based intra-luminal device for non-traumatic holding of the second intra-luminal device a barb member extending from the strut, such that the barb member is housed within the cell in the collapsed state and extends beyond the outer diameter of the first percutaneous intra-luminal device in the expanded state to facilitate anchoring.
