Abstract: A tissue access and closure system for piercing through biological tissue and providing access to internal structures; particularly, intra-abdominal structures, and closing an opening in the tissue. The system includes a suture passer sub-system that is adapted to releasably secure sutures and insert the sutures into and through the tissue, and a suture guide sub-system that is adapted to cooperate with the suture passer sub-system, the cooperation including engaging and retaining sutures releasably secured to the suture passer sub-system after the sutures are inserted into and through the tissue with the suture passer sub-system, the suture passer sub-system and sutures are advanced into the suture guide sub-system, and the suture passer sub-system and sutures are subsequently withdrawn out of the suture guide sub-system.

Abstract: A suture passer includes a shaft having an axis, a first jaw mounted to the shaft in alignment with the axis, the first jaw being configured to releasably support a length of suture thereon; a second jaw movably mounted to the shaft, and a needle movably mounted to the shaft, the needle having a hook and being configured to reciprocate in alignment with the axis so that the hook can selectively pass by the second jaw and engage suture releasably supported on the first jaw, wherein the first jaw comprises a spring for selectively binding the suture to the first jaw, and further wherein the spring comprises a recess for receiving the suture therein.

Abstract: A system for passing suture through biological tissue using a cannula, introducer or other minimally invasive means, to approximate, ligate, fixate, and/or close biological tissue. The system includes a hand actuator mechanism, an elongated tubular member housing a deformable tubular needle therein in operative communication with the hand actuator mechanism, and a jaw mechanism disposed on the tubular member distal end.

Abstract: A trocar wound closure system includes a suture passing needle and a guide for directing the needle through the wound site. A distal portion of the needle includes a capture rod with a slot. An obturator tube with a cutout section can be axially actuated to align the cutout section with the slot, and then moved out of alignment so as to capture the suture. The guide includes at least two tracks for directing the needle through the tissue track. A suture catcher is located adjacent to the exit of each track and configured to be actuated from a radially extended configuration to a retracted configuration so as to capture the suture section inserted through each loop. Radially expandable arms at distal section are movable between an expanded configuration and a slender configuration.

Abstract: A system for piercing through biological tissue and providing access to internal structures; particularly, intra-abdominal structures, and closing an opening in the tissue. The system includes a suture guide sub-system having a tissue positioning sub-system for engaging segments of tissue disposed proximate the tissue opening and a suture passer sub-system that slideably engages the suture guide sub-system. The suture passer sub-system includes suture deployment and capture means that is configured to removably secure a suture thereto and deliver the suture to the segments of tissue disposed proximate the tissue opening.

Abstract: A dual functioning instrument set, comprising a needle and guide, has not only the capabilities to enter and insufflate the abdominal cavity but also the ability of a suture passer to carry and retrieve suture for closure of the incision sites at the end of the procedure. The needle contains a deployable snare that is used to pass and retrieve suture. The guide is used to repeatedly locate the needle relative to the inner abdominal wall allowing for consistent placement of sutures. For insufflation purposes, obturator tips having different distal structures are provided for shielding the sharp needle tip after insertion through a body wall.
