A device and method for forming an anastomotic joint between two parts of a body

Abstract

A device and method for forming an anastomotic joint between two parts of a human or animal body having a hollow connector with at least two proximal arms biased towards an open position; and at least two distal arms biased towards an open position, wherein in use when pressure is applied to the proximal arms to overcome the bias into a position in which the proximal arms are closer to each other; similarly pressure is applied to the distal arms to overcome the bias into a position in which the distal arms are closer to each other; the distal end can be pushed into a passage in the first human or animal body part until the distal arms are located in the first lumen of the first body part and released allowing the distal arms to move to the biased position to urge against the first lumen of the first body part; and the proximal end can be pushed into a passage in the second human or animal body part until the proximal arms are located in the second lumen of the second body part and released allowing the proximal arms to move to the biased position to urge against the second lumen of the second body part.

Description

[0001] This application claims the benefit of US Provisional Patent Application No. 61 / 759,642, filed February 1, 2013, the entire contents of which are incorporated herein by reference for all purposes. technical field [0002] The present invention relates to an apparatus or method for forming an anastomotic joint between two body parts. Background technique [0003] An anastomotic joint is a connection between two body tube bundles that allows fluid to pass between the two body tube bundles. Essentially, an anastomotic joint is a communicating opening. Examples of natural anastomotic joints include the junction between the bladder and urethra, between blood vessels, and the junction of different segments of the gastrointestinal tract. [0004] A surgical anastomosis is an artificial connection between two body structures. It usually means creating connections between tubular structures such as blood vessels, the curvature of the intestine, or the gastrointestinal tract....

AI Technical Summary

Problems solved by technology

Although, many attempts have been made to improve sutures by using nonabsorbable suture materials (cotton, nylon, stainless steel); absorbable sutures (gut, polyglycolic acid, polydioxanone, polyglactin), or Atraumatic needles reduce damage to the wall, but it is difficult to minimize wall damage

Currently, the only way to reduce or minimize damage is through the skill of the surgeon, which is highly individual and cannot be completely ruled out in this way
