Embodiment approach

[0045] According to an alternative embodiment, the proximal part 26 comprises a hole 40, for example for a suture to be passed therethrough, which can be used to separate the proximal part from the distal part.

[0046] According to an alternative embodiment, the distal part 28 comprises a head 42 and a stem 44 formed along the longitudinal axis 30 , preferably manufactured in one piece.

[0047] The head 42 preferably has a frusto-conical shape and according to an alternative embodiment comprises a hole 46 for a suture to be passed therethrough, which can be used, for example, to connect the distal part to the proximal Parts separated.

[0048] According to an alternative embodiment, the rod 44 preferably has a cylindrical configuration and its free end, ie the end opposite the head 42 , is widened to form a preferably annular base 48 .

[0049] Channel 50 extends along longitudinal axis 30 from the end of head 42 to base 48 and is adapted to receive therein Figure 4 or th...

Abstract

An apparatus for drawing tissue together and forming an anastomosis, comprising a main guide wire (66, 86) adapted to receive and approximate a portion (A; B) of tissue to be joined by an anastomosis. The main guide wire (66, 86) is adapted to be shaped as an open loop passing through the portion (A, A'; B, B') of tissue to be joined by anastomosis, the main guide wire (66, 86) ends are different and distinguishable from each other. The main guidewire (66, 86) has a tubular or hollow structure adapted to receive at least one needle for perforating tissue by pushing or radio frequency.

Description

technical field [0001] The present invention generally relates to devices and methods for obesity treatment. In particular, the present invention relates to a device for drawing together tissue suitable for use in a method for performing an anastomosis in the canal of the alimentary canal. [0002] The invention also relates to a method for performing an anastomosis in the canal of the alimentary canal. Background technique [0003] Currently, surgical anastomoses are difficult to perform through endoluminal access. In practice, most anastomoses are formed by using open or laparoscopic surgical techniques. [0004] Accordingly, no effective surgical instrument is available to provide the guidance and control needed to properly draw tissue surfaces together and / or connect surfaces and passages through a body cavity (anastomosis). Contents of the invention [0005] The central problem of the present invention is to provide a device that can draw tissue together and that c...
