A suture clip applier for applying a suture around a tubular tissue adjacent to an open lumen. The suture clip applier includes an elongated body having a tissue clinching mechanism at one end of the body. The tissue clinching mechanism comprises two arms that are movable between open and clinched positions. The suture clip applier includes a plurality of deformable suture clips mounted along a longitudinal length of the elongated body, wherein each suture clip is configured to be detachably positioned within an interior of the two arms and to be deformed between open and clinched positions in response to the two arms being moved between the open and clinched positions. The suture clip applier further includes a length of suture comprising a pre-formed adjustable fastening and a loop extending from the pre-formed adjustable fastening, the loop extending between the two arms.

A surgical stapler for applying a suture to tissue includes a first jaw and a second jaw configured to receive a cartridge. An actuation mechanism translates a drive member distally through the first and second jaws to apply staples to tissue such that a suture, in combination with the staples, forms a purse string when the stapler activated. The cartridge includes a first upper portion and a second lower portion.

A ligation clip includes first and second beams that are movable in relation to each other from an open position to a clamped position to define an opening that is dimensioned to be received about end portions of vessel portions to be joined together during an anastomosis procedure to secure the end portions to an anvil shaft and/or an anvil retainer of a circular stapling device. The use of ligation clips to perform this function obviates the need to form a purse suture in the end portions of the vessel portions during the anastomosis procedure and reduces the amount of time required to perform an anastomosis procedure.

A purse string suture passing device includes a clamp member and a suture passer housing assembly. The clamp member is dimensioned to be received within a guide channel of the suture passer housing assembly and includes two jaws that each define a longitudinal passage. The suture passer housing assembly includes two needles that are supported within the guide channel and are received within the longitudinal passages of the clamp member as the clamp member is inserted through the guide channel. Each of the needles receives a suture passer that includes a distal portion that is configured to engage a suture after the clamp member is received within the guide channel. When the suture is attached to the suture passers, the clamp member can be removed from the guide channel to apply a purse string suture to the tissue.

A method for delivery and deployment of a prosthetic mitral valve into a heart includes inserting an introducer sheath having a prosthetic mitral valve disposed therein in a collapsed configuration into the left atrium of a patient's heart, through a gap between the native mitral valve leaflets, the left ventricle and apex of the heart. An epicardial pad device coupled to the prosthetic valve via a tether is moved distally out of the sheath. The introducer sheath is withdrawn into the left atrium of the heart. An inner delivery sheath is extended distally from within the introducer sheath and disposed within the left atrium. The prosthetic mitral valve is moved distally out of the inner delivery sheath and assumes a biased expanded configuration. The valve is positioned within the mitral annulus of the heart, and secured in place via the tether and epicardial pad device.

A computer-implemented method for controlling a surgical stapling instrument for stapling tissue includes advancing an anvil assembly in relation to a staple cartridge to a first position defining a tissue gap between the staple cartridge and the anvil assembly and clamping tissue, the clamped tissue including a suture, measuring a first force of tissue compression of the tissue clamped within the tissue gap with the anvil assembly at a first time point, determining whether the measured first force is greater than a threshold, measuring a second force of tissue compression of the tissue clamped within the tissue gap at a second time point in response to the determination that the first force is greater than the threshold, determining whether the suture failed based on the measured second force being an amount less than the measured first force, and stopping the advancing of the anvil assembly based on the determined suture failure.

A purse string suture instrument includes an end effector with first and second jaws disposed at a distal portion of an elongate tubular shaft. The first and second jaws are pivotably coupled to each other and to the elongate tubular shaft. The first and second jaws are spaced apart and define a gap therebetween. First and second pluralities of teeth extend perpendicularly from the first and second jaws respectively, and the first plurality of teeth is longitudinally offset from the second plurality of teeth. The first and second jaws are transitionable between open and approximated configurations. The approximated configuration is adapted to clamp tissue in the gap between the first and second jaws, thereby displacing sections of tissue outwardly between the first and second pluralities of teeth.

A surgical staple cartridge is disclosed comprising a strip of staples removably stored within the surgical staple cartridge. The strip of staples comprises a plurality of staples, a base strip, and a plurality of connector portions joining the staples to the base strip.

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.
