Patent ID: 8579933

Claim:
A medical device for deploying a mechanical closure device to facilitate closing a passageway in a body comprising: a first tubular structure having proximal and distal ends, the distal end being tapered to a sharp edge sufficient to penetrate tissue, the first tubular structure being sufficiently flexible and configured to be delivered transluminally through the body to the passageway; a second tubular structure substantially coaxial to and slideably engaged within the first tubular structure, the second tubular structure comprising a shape memory material and being configured to assume a first substantially linear shape when constrained within the first tubular structure, and resume a second pre-determined curvilinear shape to change the orientation of the second tubular structure relative to the first tubular structure when telescopically extended from the distal end of the first tubular structure, the second tubular structure being tapered to a sharp edge sufficient to penetrate tissue; and a third tubular structure substantially coaxial to and slideably engaged within the second tubular structure, the third tubular structure having luminal and abluminal surfaces, the luminal surface forming an internal chamber, the internal chamber being configured to accept at least a porting of the mechanical closure device, the third tubular structure further configured to provide sufficient rigidity to push the mechanical closure device from the distal end of the second tubular structure, and provide sufficient flexibility to assume a curvilinear shape when deflected by the second tubular structure.
