A method of making a suture needle having a bendable region includes obtaining a suture needle made of a martensitic alloy having an austenitic transition temperature. The suture needle has a proximal section, a distal section with a sharpened tip, and a bendable region located between the proximal and distal sections. The method includes heating the suture needle to a first temperature that is greater than the austenitic transition temperature of the martensitic alloy and quenching the suture needle to room temperature to harden the martensitic alloy, After heating and quenching, the bendable region of the suture needle is heated locally to a second temperature that is above 800 degrees Celsius, but below the austenitic transition temperature of the martensitic alloy so that the bendable region is softened and made more flexible relative to the proximal and distal sections of the suture needle.

The disclosure includes a vein ablation system, comprising a catheter having an elongated body. In some embodiments, the vein ablation system comprises an ablation device at a distal portion of the elongated body. According to some embodiments, the vein ablation system comprises a control device at a proximal portion of the elongated body. The control device may comprise an input mechanism configured to simultaneously control at least two of a longitudinal translation of the ablation device through a target vessel, a rotation of the ablation device about a central longitudinal axis, and an infusion of a chemical agent into the target vessel.

A suture system can comprise a first and a second curved double arm needle, and a needle docking device configured to maintain the first and the second curved double arm needles in alignment with and parallel to one another and at predetermined orientations relative to the needle docking device. The system can include a needle manipulating instrument having a distal portion configured to engage the first and the second curved double arm needles while the first and second curved double arm needles are in the needle docking device, and to maintain the needles in predetermined orientations.

The present disclosure generally pertains to methods and kits for preparing an ACL repair surgical implant, the method including drilling femoral and tibial bone plugs of a tendon graft to create medial to lateral holes, and passing a braided suture around the tendinous portion of the tibial end, through soft tissue, and out the tibial end. Next, an anterior to posterior femoral hole is drilled, and a flat-braided suture is passed through the femoral medial to lateral hole and, using a bent needle, passed through junctions of the femoral bone plug and the tendinous portion and out through junctions of the tibial bone plug and the tendinous portion on both sides of the graft. Ends of the flat-braided suture are crisscrossed through the medial to lateral tibial hole. A bone-to-bone fixation suture assembly is passed through the anterior to posterior femoral hole.

A stitching device includes an end effector having first and second jaw members and first and second pins, a stationary cam, and a rotary cam. The first pin is supported on the first jaw member and the second pin is supported on the second jaw member. The stationary cam defines a first cam slot, and the rotary cam defines a second cam slot. The first and second cam slots receive the first and second pins and are configured to releasably secure one of the first or second jaw members to the rotary cam such that the first and second jaw members rotate about the stationary cam in alternating fashion. During each revolution of the rotary cam, the one of the first or second jaw members rotates with the rotary cam a substantially full revolution while the other of the first or second jaw members remains stationary.

An endoscope device including an endoscope body, a suture device, and a needle. The endoscope body has a proximal portion and a distal portion opposite each other and includes a working channel. The suture device includes a first arm and a second arm opposite each other. The working channel connects the proximal portion and the distal portion. The first arm and the second arm extend toward a distal direction. At least one of the first arm and the second arm are pivotally connected to the distal portion and can be opened or closed with respect to the other. The operation method thereof is also provided.

Devices and methods of endolumenal formation of gastric sleeves are described. Some embodiments allow templating of a gastric sleeve by a gastric bougie, exposing a selected amount of tissue for suturing access, while maintaining sufficient internal working space for suturing within the template lumen.
