    摘要: The invention relates to an elongated torque tube for use in medical applications. The torque tube comprises an elongated tubular structure having a cylindrical cross section and defining a longitudinal axis and a circumferential axis, the elongated tubular structure including a helical cut having a finite thickness and extending along the length of the elongated tubular structure, the helical cut being aligned with the circumferential axis and including a plurality of protrusions extending along the longitudinal axis, the protrusions defined by discontinuous cuts aligned with the longitudinal axis.

    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.
