A surgical device, or a portion of a surgical device, that places purse string sutures in tissue within a body (e.g., intra-peritoneal space). The surgical device includes, or an end effector for a surgical device includes, a jaw assembly, staple cartridges, and a suture.

Laparoscopic purse string suture device

A circular stapling device is described that is particularly suited for creating stomas. The circular stapling device includes two tool assemblies. The first tool assembly is adapted to create a reinforced incision in tissue, e.g., the rectus sheath, through which a vessel portion, e.g., colon, small intestine, etc. can be pulled through during a surgical procedure. The second tool assembly is adapted to attach a stomal sleeve within the vessel portion such that the stomal sleeve extends from the stoma.

Circular stapling device and method of use

Side bite surgical suturing instruments or portions thereof for endoscopic, laparoscopic, endoluminal, and/or transluminal suturing facilitate the use of larger needles to get a bigger bite while suturing.

Surgical suturing instruments

A tool assembly includes a cartridge assembly or a heating assembly along with an anvil assembly, and a drive assembly. The drive assembly includes a working member and a laser probe that is pivotally supported on the working member and emits a laser beam. The laser probe is positioned between the cartridge and anvil assemblies such that the laser beam extends across a tissue gap of the tool assembly when the tool assembly is in the clamped position.

An endoluminal pursestring device is provided and includes a handle assembly, a shaft, an elongated fork, a plurality of surgical fasteners disposed with the shaft, and a suture engaged with the surgical fasteners. The suture is secured to a head of each of the surgical fasteners, and extends proximally through the handle assembly. In use, a distal end of the endoluminal pursestring device is positioned adjacent tissue surrounding a lumen, and the handle assembly is rotated to cause the distal-most surgical fastener to be rotated into the tissue. The following surgical fasteners are also rotated into other portions of the tissue surrounding a lumen. The suture connecting each of the surgical fasteners is then pulled such that the surgical fasteners are pulled together, thereby closing the lumen.

Endoluminal pursestring device

The presently disclosed stapling device includes a stomal sleeve secured to an anvil assembly of a tool assembly of the stapling device. The stomal sleeve has a tubular configuration having a first end portion secured to a tissue contact surface of the anvil assembly and a second end portion secured to a distal face of an anvil head of the anvil assembly. In use, the stapling device is fired to secure the first end portion of the stomal sleeve to dermal and intestinal tissue within a stoma and to separate the first end portion of the stomal sleeve from the anvil assembly. When the stapling device is withdrawn from the stoma, the second end portion of the stomal sleeve is withdrawn from the stoma and subsequently disengaged from the anvil head of the anvil assembly such that the second end portion of the stomal sleeve is positioned externally of the stoma.

Device and method for attachment of a stomal sleeve

A stomal diverter device includes a catheter, a stoma rod, and a bracket. The catheter includes a first tube having an open end, a second tube spaced from the first tube having a closed end, and a drain tube. The stoma rod is positioned between the first and second tubes and includes structure to releasably attach the stoma rod to the abdomen of the patient. The bracket is supported on the catheter and the stoma rod and defines a locking feature that is configured to engage a mating feature of the stoma rod to secure the catheter between the stoma rod and the bracket.

A surgical suturing instrument includes first and second jaw members each defining a hole for detachable receipt of opposite ends of a curved needle. The first jaw member is rotatable relative to the second jaw member to move and transfer the curved needle between the jaw members. A first elongate locking element is slidable within the first jaw member between non-locking and locking positions. When the first elongate locking element is in the locking position and the curved needle is disposed within the hole of the first jaw member, a portion of the first elongate locking element is received in a notch defined in an end of the curved needle to selectively secure the curved needle to the first jaw member.

A surgical suturing apparatus includes an end effector including a jaw assembly and a needle assembly. The jaw assembly includes first and second jaws movable between open and closed positions. Each of the first and second jaws includes a tissue facing surface having an elongated rail and a longitudinal row of teeth. Each tooth of the longitudinal rows of teeth of the first and second jaws includes a needle channel extending therethrough. The elongated rails and the longitudinal rows of teeth of the first and second jaws are disposed in opposed relation relative to each other. The needle assembly includes a first needle, a second needle, and a suture coupled to the first and second needles. The first needle is slidable through the needle channels of the first jaw and the second needle is slidable through the needle channels of the second jaw.

A method for accessing matter within an intestine, includes creating an opening extending through an abdominal wall of an abdominal cavity, accessing an intestinal end segment of an intestine within the abdominal cavity, positioning the intestinal end segment of the intestine in registration with the opening extending through the abdominal wall, attaching the intestinal end segment to cutaneous tissue surrounding the opening to establish fluid communication between a lumen of the intestine and the opening through the abdominal wall, securing an access device adjacent the opening through the abdominal wall and connecting a receptacle to the access device configured to be in fluid communication with the lumen of the intestine to collect matter within the intestine.
