摘要：
A device and method for deploying a mechanical closure device for closing a passagewayin a body, for example a patent foramen ovale (PFO) in a heart. The deployment devicehas a first tubular structure having proximal and distal ends. A second tubularstructure is substantially coaxial to and slideably engaged within the firsttubular structure. The second tubular structure has a first substantially linearshape when constrained within the first tubular structure, and a second curvilinearshape when telescopically extended from the distal end of the first tubular structure.A third tubular structure is substantially coaxial to and slideably engagedwithin the second tubular structure. The third tubular structure is configuredto provide sufficient rigidity to push the mechanical closure device from thedistal end of the second tubular structure, and provide sufficient flexibilityto assume a curvilinear shape when deflected by the second tubular structure.
