A tubular tissue transformer (TTT) for a tubular tissue structure. The tubular tissue transformer has a plurality of leaves and a plurality of retainers on each of the plurality of leaves. Each retainer retains the tubular tissue structure on the respective leaf. Also provided are a coupling system to coupling tubular tissue structures together and tools and methods for attaching and widening otubular tissue structures.

Technologies are generally provided for a tissue removal device for removing tissue protrusions extending from a wall of intestines. The tissue removal device may be a bell shaped tube configured to slide over an inflamed diverticulum that has been inverted to extend into interior space of the colon. The tissue removal device run be slid over the inverted diverticulum with a portion of the tissue removal device having a widest diameter oriented near the colon wall and a portion having a narrowest diameter oriented near a tip of the diverticulum. A pressure gradient may be induced along the walls of the tissue removal device such that the point of highest pressure at the narrowest opening may cause the walls of the diverticulum to be pinched together to induce necrosis and removal of the diverticulum, while promoting healing of the colon walls over the region of decreasing pressure.

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.

A tissue pressing tool includes: a shaft that extends in one direction; a tissue pressing part that is a rod-like or belt-like member having a rigidity enough to hold a shape thereof even when pressed against a tissue; and a passive bending part that is arranged between the tissue pressing part and the shaft so that the tissue pressing part is capable of bending in all direction around an axis line of the shaft so as to keep an inverted state of the tissue by the tissue pressing part pressing the tissue linearly

Various embodiments of the present disclosure include an apparatus comprising a clip which includes a first side including a first ring configured to pass over an end of a first vessel, the first ring configured to engage the first side with the first vessel, and a second side coupled to the first side, the second side including a second ring configured to pass over an end of a second vessel, the second ring being configured to engage the second side with the second vessel. The first and second sides, when in a closed position, are configured to maintain the first and second vessels in substantially end-to-end contact.

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.

Disclosed embodiments include apparatuses, systems, and methods for facilitating surgical anastomosis between bodily passages. In an illustrative embodiment, an eversion mechanism is configured to partially evert a distal portion of an opening of a receiving passage and further configured to leave a proximal portion of the opening of the receiving passage in a non-everted position. A donor support mechanism is configured to partially evert a distal portion of an opening at an end of a donor passage and further configured to leave a first proximal portion of the end of the donor passage in a non-everted position. The donor support mechanism is further configured to form a passage juncture at the end of the donor passage and the opening of the receiving passage. A suturing mechanism is configured to motivate a filament through a generally helical path around the passage juncture to suture the donor passage to the receiving passage.

An everter device includes a handle and at least one eversion tip. The handle has a first end and a second and each of the at least one eversion tip is coupled to a respective end of the handle. Additionally, the at least one eversion tip has a respective distal end, a respective proximal end, and a respective eversion surface. A sizing device includes a handle and at least one sizing guide. The handle has a first end and a second end. Each of the at least one sizing guide is coupled to a respective end of the handle. Additionally, the at least one sizing guide has a plurality of sizing apertures and associated sizing indicators. The everter device and the sizing device may be provided together as a kit.

Disclosed embodiments include apparatuses, systems, and methods for facilitating anastomosis between bodily passages. In an illustrative embodiment, an eversion mechanism is configured to engage a first external surface of a receiving passage adjacent a first opening in the receiving passage in order to create a receiving flange presenting a first interior face. A donor support mechanism is configured to support a donor passage with an opening in an end in an everted position that forms a donor flange presenting a second interior face. The donor support mechanism is further configured to present the second interior face of the donor flange against the first interior face of the receiving flange to present a passage juncture. A suturing mechanism is configured to motivate a filament through a helical path around the passage juncture to suture the second interior face of the donor passage to the first interior face of the receiving passage.
