Abstract:

A device and method for deploying a mechanical closure device for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart. The deployment device has a first tubular structure having proximal and distal ends. A second tubular structure is substantially coaxial to and slideably engaged within the first tubular structure. The second tubular structure has a first substantially linear shape when constrained within the first tubular structure, and a second curvilinear shape when telescopically extended from the distal end of the first tubular structure. A third tubular structure is substantially coaxial to and slideably engaged within the second tubular structure. The third tubular structure is 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.
