Disclosed are a lead method of suturing an acutely ruptured Achilles tendon and a device used in it. The suturing device includes a suture line, guide lines, a clamping instrument and suture needles. As performing suturing, the clamping instrument is inserted into the fascia sheath of Achilles tendon to clamp Achilles tendon, the suture line and the guide lines are made to penetrate Achilles tendon and skin through the threading hole on the clamping instrument by the suture needle, wherein the suture line is located far away from Achilles tendon rupture; the guide lines are used to guide the suture line, so that both ends of the suture line can penetrate Achilles tendon in turn along the guide lines, and the suture line is tightened and knotted on the two ruptured Achilles tendons.

A repaired tendon includes a proximal tendon section having a free end, and a distal tendon section having a free end that opposes the free end of the proximal tendon section. Four bidirectional barbed sutures are implanted in the repaired tendon for approximating the free end of the proximal tendon section with the free end of the distal tendon section. Each of the four bidirectional barbed sutures includes a proximal section having proximal barbs that engage the proximal tendon section, a distal section having distal barbs that engage the distal tendon section, and a stop located between the proximal and distal barbs that engages the approximated free ends of the proximal and distal tendon sections. The bidirectional barbed sutures have first suture bites and second suture bites that are shorter than the first suture bites.

A method for anastomosing an alimentary tract according to a first aspect of the invention includes a first step of inserting an endoscope into an alimentary tract through a natural opening in a state where a distal end part of a tube body is coupled to an outer periphery of a distal end part of the endoscope; a second step of making a hole in a tract wall of the alimentary tract; a third step of inserting the tube body through the hole; a fourth step of grasping the distal end part of the tube body disposed through the hole; a fifth step of separating the tube body from an outer periphery of the distal end part of the endoscope; and a sixth step of delivering the treatment part up to the hole after the fifth step.

Devices, systems, and methods described herein relate to affecting an internal diameter of a body lumen, and, in many examples, of a pylorus. A silk-based bulking agent may be injected in a pyloric tissue so as to reduce an effective inner diameter of the pylorus. A multi-part occluding agent may be injected into a pylorus on the surface of the pyloric tissue to occlude the pylorus alone or in combination with the silk-based bulking agent.

A surgical instrument that includes an elongated shaft that defines defining a central axis. The elongated shaft may have a distal end portion that is configured to operably support a circular staple cartridge therein. A tissue acquisition shaft may be axially movable within the elongated shaft such that a distal end portion of the tissue acquisition shaft may be distally advanced beyond the distal end portion of the elongated shaft. At least one tissue acquisition member may be pivotally attached to the distal end portion of the tissue acquisition shaft such that at least one tissue acquisition member is selectively pivotable about a corresponding acquisition axis that is substantially parallel to the central axis from a retracted position to deployed positions upon application of a deployment motion thereto. Various embodiments include an annular cutting member that is supported by the distal end of the elongated shaft for selective axial travel relative thereto.

A tissue clipping device and system, and method for clipping tissue are disclosed. The tissue clipping device includes a clip with clip arms that is slidably disposed within a channel of a lock tube. The clip is designed to move between an open configuration in which distal ends of the clip arms are separated from each other for receiving tissue therebetween, and a closed configuration in which the distal ends of the clip arms are closer to each other than in the open configuration for clipping the tissue received therebetween. The tissue clipping system further includes a delivery device for delivering and deploying the tissue clipping device. The delivery device is releasably coupled to the tissue clipping device.

An apparatus for irrigating the vas deferens in connection with a vasectomy reversal is described. The apparatus comprises a fluid delivery device having a first portion that connects to the vas deferens, the fluid delivery device connecting such that a catheter tip inserts into the vas deferens and is held in stable position relative thereto and such that fluid enters the vas deferens through the catheter tip.

Disclosed is a medical device that is capable of grasping multiple sites of one object or multiple objects simultaneously. The medical device includes a platform and a plurality of pincer sets that are attached to the platform. The plurality of pincer sets extend from the platform at varied lengths and at individually operable. Accordingly, a plurality of surgical sites are grasped simultaneously and independently using multiple pincer sets.

An electrosurgical instrument for making an end-to-end anastomosis between two hollow organ sections includes two tools movable relative to each other and each including an HF electrode by which the hollow organ sections can be fusion-welded to each other. The two tools are substantially sleeve-shaped or can at least be brought into sleeve shape so that a first tool can enclose a first hollow organ section and a second tool can enclose a second hollow organ section. Each of the electrodes is formed on an end face of each sleeve-shaped tool around which the respective hollow organ section can be everted inside out, and the two tools are movable relative to each other so that the electrodes are aligned and can clamp the everted hollow organ sections therebetween.
