The present invention is directed to gastrointestinal or enteric (including biliary) anastomosis and the like. The anastomotic device of the invention is a three dimensional woven tube of wire. The outer loops or ends of the tube fold or loop back on deployment in a manner which holds the luminal interface of the anastomotic site into apposition at the deployment site. The woven tube is deployed using a protective sleeve and nose assembly. Adjustment of the wire diameter and/or material properties of the wire can cause the anastomotic device to remain in place permanently or, for example, in the case of the intestine to slough through the two apposing walls of the lumen resulting in the device safely passing through the intestine leaving a naturally healed, properly functioning anastomosis.
A method of deploying an anastomosis device, comprising mounting a woven tube of wire having a first end and a second end inside a protective sleeve, inserting the device into a body cavity through a trochar or tube to a predetermined puncture site of a first segment either proximal or distal to a desired anastomotic site, advancing the device intraluminally to the anastomotic site either manually or with the aid of a guide wire, bringing a second tissue segment into close apposition to the first segment at the anastomotic site, piercing a wall of the first segment and a wall of the second segment and into a lumen of the second segment, deploying the tube from the protective sleeve at a juncture of apposing puncture holes created by the device, and forming a petal configuration wherein the first end and the second end of the tube form interdigitated petals at the anastomotic site to hold the two segments in apposition.
A method of deploying an anastomosis device, comprising mounting a woven tube of wire having a substantially constant diameter between a first end and a second end inside a protective sleeve, inserting the device into a body cavity through a trochar or tube to a predetermined puncture site of a first segment either proximal or distal to a desired anastomotic site, advancing the device intraluminally to the anastomotic site either manually or with the aid of a guide wire, bringing a second tissue segment into close apposition to the first segment at the anastomotic site, piercing a wall of the first segment and a wall of the second segment and into a lumen of the second segment, deploying the tube from the protective sleeve at a juncture of apposing puncture holes created by the device, and forming a petal configuration wherein the first end and the second end of the tube form interdigitated petals at the anastomotic site to hold the two segments in apposition.
