    摘要： Valve prosthesis systems and methods/systems for placement of such valve prostheses are provided that facilitate efficient, reliable and minimally invasive delivery modalities. The placement systems and methods permit remote manipulation and positioning of the valve prosthesis such that desirable placement relative to anatomical structures, e.g., the heart annulus, may be achieved. The valve prosthesis includes a resilient ring, a plurality of leaflet membranes mounted with respect to the resilient ring, and a plurality of positioning elements movably mounted with respect to the flexible ring. The delivery system includes a first elongate element that terminates at the valve prosthesis and is manipulable by an operator to remotely rotate the positioning elements relative to the flexible ring. A second elongate element terminates at the valve prosthesis and is manipulable by an operator to remotely advance the valve prosthesis downward into an anatomical annulus. The second elongate element may be manipulated to remotely advance the valve prosthesis into the anatomical annulus to assume a position for supporting post-implantation function of the valve prosthesis in situ. The first elongate element may be further manipulated to remotely rotate the positioning element relative to the flexible ring to cause the positioning element to engage tissue associated with the anatomical annulus and to thereby maintain the post-implantation position of the valve prosthesis in situ. Methods for valve prosthesis deployment are also provided.

    摘要： A valve assembly is provided for permitting the introduction of a surgical instrument into a patient's body while providing a substantial seal about the instrument. The valve assembly includes a sealing gasket assembly providing a fluid tight seal before instrument insertion, and is configured and dimensioned for accommodating an instrument and providing a substantial fluid tight seal after insertion of an instrument. The valve assembly may further include a deformable sealing member having a substantially central aperture for accommodating the instrument. The sealing member provides a substantial seal about the instrument when the instrument is passed therethrough impeding the egress of fluids and gasses through the valve assembly.

    摘要： An apparatus is disclosed for automatically locking an obturator housing to a cannula housing of a trocar assembly when the obturator is advanced to a predetermined distal position. Two latch devices are mounted for pivotal movement within the obturator housing with each having at least one latch positioned at one end thereof. The pivoting latch devices are automatically pivoted into locked engagement with partial apertures or indentations in the cannula housing such that the obturator housing is secured to the cannula housing. Biasing springs are provided to automatically pivot the pivoting latch devices out of engagement with the cannula housing when the obturator is withdrawn to its proximal position.
