Devices and methods for reconnecting or supporting torn, damaged or weak tissue are disclosed. The disclosed embodiments can be used on long slender tissue such as ligaments, tendons, nerves, vessels, intestines, muscles, bones, appendages and any other elongate tissue within the body, of both humans and other animals. The devices can wrap around elongate tissue and is capable of supporting the tissue or keeping two severed ends in close proximity to one another. The devices can be used in addition to or in lieu of sutures. The devices can function similar to a Chinese Finger Trap and are capable of decreasing in diameter upon extension, thus constricting upon the tissue. The multiple coils of the devices can make sufficient surface contact on the ligament or tendon, using friction to keep the device in place, while also allowing access for diffusion of oxygen and nutrients.

A slide slot type multi-arm clamp includes a handle, a catheter, a clamping portion, a spring tube and a control line. In practical applications, a surgical operator applies an axial thrust and a pulling force to the handle to drive the control line to move, so as to open/close and lock the clamping portion. Moreover, side clamp arms and a clamp base in the clamping portion can be easily separated from the catheter or the spring tube to stay in a human body so as to achieve the functions of hemostasis and tissue suture. The side slot type multi-arm clamp can achieve the effect of minimizing the length of the instrument retained in the human body by the cooperation between the side clamp arms and the clamp base.

Systems and methods introduce and prosthesis into a blood vessel or hollow body organ by intra-vascular access. The prosthesis is secured in place by fasteners which are implanted by an applier that is also deployed by intra-vascular access. The applier is configured to permit controlled, selective release of the fastener in a step that is independent of the step of implantation.

A surgical implant comprising a receiver member and deployment member for clamping and sealing tissue of variable thickness, a corresponding applicator tool and surgical system for connecting, sealing, fastening and/or attaching tissue to itself, to other tissue and/or to non-tissue structures, and/or sealing the flow of fluid at and/or between structures such as tissue and vessel structures.

A device for treating tissue includes a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough, the capsule releasably coupled to a proximal portion of the device and clip jaws, proximal ends of which are slidably received within the channel of the capsule so that the clip jaws are movable between an open configuration and a closed configuration. Clip jaws are configured so that a distance between the distal ends of the clip jaws in an open configuration is between 15 and 18 millimeters. Clip jaws further include barbs extending from a distal portion thereof.

A device and system are described that are capable of isolating at least one targeted tissue and forming an anastomosis between two internal body structures though a completely endoscopic procedure. Further, the device and system described generally comprise two tubular members that are capable of moving in a telescopic fashion relative to one another. Additionally, a method is described for using the device and/or system to bypass the duodenum from digestion.

A surgical clip includes a first clamping leg and a second clamping leg, the two clamping legs, when in use, being movable towards each other such that they squeeze a blood vessel shut and are linked to each other via a connecting piece which applies a closing force forcing the two clamping jaws towards each other, with two additional springs being provided in addition to the connecting piece which functions as the main spring and amplifying the closing force, the additional springs being arranged in parallel to the main spring and acting in opposite directions.

A clip device for an endoscope of the present invention comprises an outer tubular body 70; an inner tubular body 80 provided in the outer tubular body 70; a line member 50 placed in the inner tubular body 80; and a pinching part 20, for holding an indwelling clip, connected to a distal side of the line member 50; wherein the pinching part 20 has two pinching base plates 30a and 30b, a blade part 40a is provided at a distal end of the pinching base plate 30a and formed toward an inside of the pitching base plate 30a, a blade part 40b is provided at a distal end of the pinching base plate 30b and formed toward an inside of the pinching base plate 30b, a Young's modulus of the blade part 40a is smaller than that of the pinching base plate 30a, and a Young's modulus of the blade part 40b is smaller than that of the pinching base plate 30b.

A device for treating tissue includes a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough, the capsule releasably coupled to a proximal portion of the device and clip jaws, proximal ends of which are slidably received within the channel of the capsule so that the clip jaws are movable between an open configuration and a closed configuration. Clip jaws are configured so that a distance between the distal ends of the clip jaws in an open configuration is between 15 and 18 millimeters. Clip jaws further include barbs extending from a distal portion thereof.

Devices, systems and methods are disclosed for the formation of an arteriovenous fistula in the limb of the patient. Embodiments include an apparatus for the creation, modification and maintenance of a fistula, including the modification of an existing dialysis fistula; and a method of supplying oxygenated blood to the venous circulation of a patient. A kit of anastomotic implants is described which supports a broad base of patient anatomies and fistula locations. The devices, systems and methods can be used to treat patients with one or more numerous ailments including chronic obstructive pulmonary disease, congestive heart failure, hypertension, hypotension, respiratory failure, pulmonary arterial hypertension, lung fibrosis and adult respiratory distress syndrome.
