A surgical kit includes a stapling device and a securing ring. The stapling device includes a reload including a trocar member and an anvil assembly including an anvil and an anvil shaft detachably couplable to the trocar member of the reload for unitary movement. The securing ring is selectively securable about the anvil shaft. The securing ring has an annular profile defining an aperture. The securing ring includes first and second portions and an intermediate portion. The first and second portions adjustably overlap each other. The first portion includes a first tab. The second portion includes a hook. The intermediate portion includes a second tab and defines slots to receive the hook of the second portion. When the first and second tabs are displaced relative to each other, the aperture is transitionable from a first state having a first diameter to a second state having a second diameter.

A surgical system, method, and apparatus for suturing a first anatomical structure to a second anatomical structure of a subject includes an endoscope tube for being advanced through a lumen of the first anatomical structure to a surgical site near the second anatomical structure. A manipulator arm extends through the endoscope tube to the surgical site, and includes a first concentric tube manipulator with an end effector configured to grasp and manipulate a suture at the surgical site. A needle arm extends through the endoscope tube to the surgical site, and includes a second concentric tube manipulator with a needle tip configured to pierce the tissue of the first and second anatomical structures. The needle arm is also configured to grasp the suture and to retract and pull the suture through the pierced tissue so that the suture extends through and forms stitching that stitches together the first and second anatomical structures.

The invention comprises a system, method, and apparatus for securing two ends of a ruptured or partially ruptured tendon in the hand or wrist during a repair, recession, or revision procedure. During this tenorrhaphy, anchoring material is inserted into the proximal ruptured surface of the tendon by an apparatus comprising multiple needles of at least two different types. Connecting material spans the site of tenorrhaphy of a ruptured tendon, or a multiplicity of ruptured tendons. In some embodiments, interlocking patterns of loop and helical suture are inserted by straight and helical needles, respectively.

The present disclosure provides tissue wrap devices with embedded three dimensional attachment features, methods of manufacturing three-dimensional attachment features for tissue wrap devices, and methods of using a nerve wrap device to protect a damaged nerve. Tissue wrap devices of the present disclosure may include a sheet of biocompatible material, the sheet having a first side, a second side, a middle portion, a first outer portion, and a second outer portion, the first side of the first outer portion being configured to overlap and interface with the second side of the second outer portion when the sheet is transitioned to a rolled configuration; wherein the first side of the first outer portion comprises a plurality of three dimensional attachment features; and wherein the plurality of three dimensional attachment features are configured to engage with the second side of the second outer portion to maintain the sheet in the rolled configuration.

A vascular anastomosis device includes a vascular jaw unit and a first vascular fastening component, wherein the vascular jaw unit is provided with a vascular anastomosis ring assembled on the first vascular fastening component. The first vascular fastening component includes a first tube provided with a first opening and a first guiding rail, a vascular positioning member connected with the first tube, a second tube arranged in the first tube, a vascular supporting unit assembled on the second tube and disposed near to the vascular positioning member, an advancing member arranged in the first tube, and a third tube arranged in the advancing member and provided with a cross rod and a guiding rod, wherein the vascular supporting unit includes a vascular supporting body and a vascular spreading member.

An apical cuff axial compression assembly including a ring member for coupling an apical cuff of a Ventricular Assist Device pump, to left ventricular apical tissue. Tissue anchors are employed to engage with the ring member and the apical cuff to exert direct or axial compression of the ring member to the apical cuff and to the left ventricular apical tissue. A first variant includes an axial compression ring and a plurality of openings to accommodate the tissue anchors. A second variant includes a segmented axial compression ring composed of a plurality of arcuate members, which may be contiguous or joined to each other or not. Each of the plurality of arcuate members has at least one tissue anchor opening passing there through.

The present invention relates to a complex surgical device for carrying out an anastomosis in the intestine including: a- a protective device (5) comprising an anchor element consisting of a stent (1) and a flexible outer sheath (2), and b- an introducer (10) comprising at least a first deformable guide tube (12), characterized in that the downstream end of said outer sheath is connected to said first guide tube (12) or to a first connecting piece (11), said outer sheath (2) being folded inside said first deformable guide tube (12), said stent being held in radial compression inside said first deformable guide tube.

Methods and apparatuses for applying tensile force to one or more tissue regions within a body. Illustratively, an implant ball including a spherical side wall is received within a tubular organ, and tensile sutures extend through the implant ball for applying a tensile force to facilitate elongation of the tubular organ.

The present invention relates to an egg-shaped stapler for intestinal anastomosis, the stapler including: an anvil head having an oval bottom inner circumferential surface; a rear head which has an oval bottom inner circumferential surface that comes into contact with the bottom inner circumferential surface of the anvil head and which includes a staple receiving port for receiving a staple along the oval bottom inner circumferential surface thereof; and a handle part, one end of which is coupled to the rear head and the other end of which extends backwards so as to operate at least one of the anvil head and the rear head.

This document relates to the apparatus and methods used in the minimally invasive creation of arteriovenous fistula (AVF). In particular, the invention relates to the creation of an AVF using catheters and an alignment methodology that is based upon detection of asymmetric electric fields. The invention finds particular application in vascular access (VA) in the hemodialysis (HD) population.
