  • Publication number: 20010056230
    Abstract: A computerized modeling tool that is used to form displayable images, which allow a user to assess the fit of a cardiac assist device within a prospective surgical patient's chest cavity. The computerized modeling tool includes a processing device that receives (i) a plurality of two-dimensional cross sectional digitized images representative of the prospective patient's chest cavity, and (ii) at least one data file representative of a three-dimensional model of the exterior of the cardiac assist device. The processing device processes this information to form a first composite displayable image of the cardiac assist device positioned within the chest cavity with selected anatomical segments displayed in uniquely associated colors presented on a display, to allow a user to view the displayable image to assess possible positions of the cardiac assist device within the chest cavity.

  • Patent number: 5084064
    Abstract: A vascular connector has a rough surfaced skirt which is trimmed to a size for surgical attachment, and a smooth central tube centrally extending through the skirt to a point upstream of the rough surface. A collar centrally affixed to the skirt releasably engages the tube, which in turn may be fabricated as a permanently attached input conduit of a total artificial heart. For installing the connectors, a skeletal frame fixture secures the central tubes or collars of plural connectors in defined positions corresponding to the attachment ports of the intended pump device.

  • Patent number: 4930674
    Abstract: A stapler for the anastomosis of blood vessels includes a vessel gripping structure, and an outwardly directed anvil head structure, and a stapler head structure adjustably positioned opposite each other. A first vessel is everted to form a cuff over one head structure, and the cuff is inserted into the end of, or into a fenestration of, a second vessel. The stapler is then activated to staple the two vessels. In a tong-like embodiment with a pair of linear anvils, a pair of sutures at openings between ends of ranks of staples completes the anastomosis. In a cylindrical embodiment with an enlarged head portion, a circular staple cartridge within the head forms a complete closure ring. In both cases the staples do not communicate with the vessel interior. Methods of end-to-end and end-to-side anastomosis are described. In one stapler instrument the vessel gripping structure is a pair of tongs with opposed outwardly-directed anvils on its jaws.
