Benefits of technology

The device effectively closes bodily organ holes by securing the loop of suture and mesh with staples, ensuring a tight seal and reducing the likelihood of reopening, while the augur-shaped blade aids in tissue engagement and staple placement.

Problems solved by technology

Conventional methods for creating and closing the gastrotomy are time consuming and increase the possibility of undesirable reopening of the gastrotomy.
However, the Welch '927 patent does not have a suture entrapped by a circle of staples deployed by a circular stapler that acts as a purse string, and has further drawbacks of lacking an augur-shaped blade.
However, the Myers '239 patent does not have a suture entrapped by a circle of staples deployed by a circular stapler that acts as a purse string, and additionally does not have an augur-shaped blade.
However, the Gingold '648 patent does not have a suture entrapped by a circle of staples deployed by a circular stapler that acts as a purse string, and cannot does not have an augur-shaped blade.
2007 / 0021759 patent application publication does not have a suture entrapped by a circle of staples deployed by a circular stapler that acts as a purse string, and has the additional deficiency of lacking an auger-shaped blade.
However, the Green 2004 / 0217146 patent application publication does not have a suture entrapped by a circle of staples deployed by a circular stapler that acts as a purse string, and further lacks an auger-shaped blade.
However, the Ahn '507 patent does not have a suture entrapped by a circle of staples deployed by a circular stapler that acts as a purse string, and has the additional deficiency of lacking an augur-shaped blade.

Embodiment Construction

[0038]In the present application, the term “proximal” refers to a direction that is generally towards a physician during a medical procedure, while the term “distal” refers to a direction that is generally towards a target site within a patient's anatomy during a medical procedure.

[0039]Referring now to the drawings, and particularly to FIGS. 1-8, a current embodiment of the viscerotomy closure device and method of use of the present invention is shown and generally designated by the reference numeral 10.

[0040]In FIG. 1, a new and improved viscerotomy closure device and method of use 10 of the present invention for closing a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure is illustrated and will be described. More particularly, the viscerotomy closure device and method of use 10 has a loop of suture 12 with a Roeder knot 14 attached to a circular mesh 16. The loop of suture 12 may be attached to the mesh 16 by weaving it through or...

Abstract

Viscerotomy closure devices and methods of use close a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure. A mesh with a hole in its center and an attached loop of suture having a Roeder knot is mounted on the protruding rod of an end-to-end anastomosis stapler between the anvil and the staple carrying member. The mesh covers the staple receiving slots. When rotated when in contact with tissue, an augur-shaped blade attached to the anvil's exterior self-feeds the tissue through a notch in the anvil's base into the space between the anvil and the staple carrying member. After the stapler is fired to staple the mesh to the tissue and create a viscerotomy, a knot pusher cinches the loop of suture and subsequently tightens the Roeder knot to maintain the cinch.

Description

RELATED APPLICATIONS[0001]The present patent document is a continuation of application Ser. No. 12 / 152,329, filed May 14, 2008, which claims the benefit of the filing date under 35 U.S.C. §119(e) of Provisional U.S. Patent Application Ser. Nos. 61 / 001,427 filed Nov. 1, 2007 and 60 / 930,284 filed May 15, 2007. All of the foregoing applications are hereby incorporated by reference.FIELD[0002]The present invention relates to a viscerotomy closure device and method of use for use in connection with closing a hole created during surgery. The viscerotomy closure device and method of use has particular utility in connection with closing a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure.BACKGROUND[0003]Viscerotomy closure devices and methods of use are desirable for closing a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure. At the inception of transgastric surgery, a gastrotomy is created ...
