  • Patent number: 5336233
    Abstract: An annuli pair provide an anastomotic clamp. Each operatively associated, opposed face of the annuli pair has a plurality of serrated impaling pins and tang-containing apertures that lockingly associated in assembly for anastomosis. The back surface of each annulus is substantially recessed about each aperture whereby to accommodate all or substantially all of the impaling pin extending past the locking tang. The annuli have alignment indicator means integral therewith to facilitate handling and assembly.
    Type: Grant

    Date of Patent: August 9, 1994
    Inventor: Fusen H. Chen
  • Patent number: 5250057
    Abstract: An anastomotic device of a pair of telescopically and frictionally locked annuli which each have a plurality of spaced retaining pins that each project from a respective outer wall of the annuli and are adapted to pierce a lumen wall to be joined, extend axially within said lumen wall and into the body of the opposed lumen wall.
    Type: Grant

    Date of Patent: October 5, 1993
    Inventor: Fusen H. Chen
  • Patent number: 5131906
    Abstract: Urethral blockage means for urinary incontinence has a centrally disposed member which may be either a solid rod or of a tubular configuration. A truncated spherical shell, fabricated of a flexible, resilient, silastic material of a predetermined stiffness and memory, depends from one end of the member. A plurality of elastic bands are uniformly spaced about and depend from the truncated end of said shell and connect to a centrally disposed, aperture-defining periphery of an insertion-limiting cap through which the member extends.

  • Patent number: 5123908
    Abstract: An anastomotic device of a pair of telescopically and frictionally locked annuli which each have a plurality of spaced retaining pins that each project from an inner wall of the annuli and are adapted to pierce a lumen wall to be joined, extend axially withiun said lumen wall and into the body of the opposed lumen wall.

  • Patent number: 5089008
    Abstract: The structure of either elongated strips or annuli for linear or tubular surgical joiner are male and female members that lock at their distal ends; have abutting planar faces at their intermediate sections for stabilizing purposes; are configured to form a void at their proximal portions for accommodating inflammation and swelling of the surgically joined parts; and have suturing pins that are each annularly slotted at their distal ends and project from a proximal edge face of one of the members, extend through partially everted parts to be surgically joined and through securing panel means formed in the opposed proximal part of the second of the members; the panel edges releasably locking into a selected annular slot for controlling clamp pressure.

  • Patent number: 4997439
    Abstract: Elongated, flexible strip, for linear or tubular surgical joinder has pluralities of primary retaining pins that extend in opposed directions and are substantially parallel to the strip face. The pins are adapted to pierce a respective tissue, extend therealong, and then extend into the opposed tissue of a surgical opening. Short retaining pins extending normal to the strip are adapted to inhibit withdrawal of the primary retaining pins. Apertures at one end of the strip operatively associate with end ones of the short pins to configure the strip for anastomosis.

  • Patent number: 4930502
    Abstract: An anastomosis device for interconnecting the ends of two tubular organs has, in a preferred embodiment, two circular members, each member having an outer region engagable against the contact surface of the outer region of the other member. When so engaged, both members are concentrically disposed about a common axis. Both members also have an inner region disposed concentrically within the outer region and including a concentric opening for receiving the end of a tubular organ. Both members also have a series of pins mounted in the inner region, disposed around the periphery of the opening and nearly parallel to the common axis so that the exposed ends of the pins approximately define a plane, for holding the ends of the tubular organ inserted into concentric opening.
