    摘要： A device 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.

    摘要： This invention relates to devices for navigating passageways in a body, and in particular, to a steerable catheter that can be used to navigate the tortuous anatomy of a body's vasculature. In one embodiment of the invention the deflectable catheter comprises an inner catheter body having a first strut spine member and a cantilevered second strut tang member. An outer catheter body is cooperatively associated with the second strut tang member and an actuator is cooperatively associated with the first strut spine member. The actuator is slideably engaged within the outer catheter body.

    摘要： The present invention is a method and device for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart, and related methods of using such closure devices for closing the passageway. The closure device includes a closure line having a first and a second end. A first expandable device is connected to the first end of the closure line. A second expandable device is located along the second end of the closure line, and is capable of sliding along the closure line in one direction while preventing sliding movement in the opposite direction. Alternatively the second closure line is fixed along the second end of the closure line.
