no. 1 approach

[0044] According to a first embodiment, the anastomosis device according to the invention makes it possible to bring the first tissue part 12 and the second tissue part 14 to be formed into the anastomosis 16 close together and against each other. In particular, the anastomosis device 10 can be used in a method for performing an anastomosis in the alimentary canal, preferably endoluminally. Alternatively, however, the stapling device 10 can be used in partially or fully laparoscopic or conventional surgical techniques.

[0045] Figure 30 An exploded view of a preferred embodiment of the anastomotic device 10 is shown, wherein the abutment portion is indicated by reference numeral 18 and the locking portion is indicated by reference numeral 20 . With particular reference to the use of the anastomotic device 10 in a method for performing a gastrojejunal (G-J) anastomosis or similar method, the abutment portion 18 may also be defined as an intestinal portion and the locking por...

Embodiment approach

[0047] According to a common embodiment of the present invention, the locking portion 20 and the abutment portion 18 are connectable or coupled to each other by pulling the first tissue portion and the second tissue portion together so as to retain the first tissue portion and the second tissue portion of mutual combination. More specifically, the locking portion 20 and the abutment portion 18 can be mutually locked in at least two locking positions corresponding to different pressure levels of the first tissue portion and the second tissue portion.

[0048] According to a preferred embodiment, the abutment portion 18 comprises at least one pin 22 capable of passing through the first tissue portion 12 and the second tissue portion 14 and into the housing 24 of the locking portion 20 in order to cooperate therewith. Preferably said pin 22 is capable of snap fitting within the housing 24 of the locking portion 20 and is locked therein. The snap fit is performed, for example, by...

Abstract

An anastomotic device (10) is suitable for approximating and keeping close to each other a first tissue portion (12) and a second tissue portion (14) intended to form an anastomosis. The anastomotic device (10) comprises an abutment portion (18) suitable for the abutment against a surface of the first tissue portion (12) and a locking portion (20) suitable for being placed opposite the abutment portion (18) with respect to the first and second tissue portion (12, 14). The locking portion (20) and the abutment portion (18) are mutually connectable through the first and second tissue portions approximated, to keep them connected. The anastomotic device (10) is suitable for being connected to a guide means comprising at least one guide wire (A, B).

Description

technical field [0001] The present invention relates generally to devices employed in methods of performing anastomoses in the digestive tract. In particular, the device is capable of performing anastomoses endoluminally, even in partially or completely laparoscopic or traditional surgical techniques. [0002] According to a first aspect, it is an object of the present invention to provide an anastomosis device which is able to bring a first tissue part and a second tissue part to be anastomosed into close proximity and keep them close together. The anastomotic device described above is particularly suitable for intraluminal application and can even be used in partially or completely laparoscopic or conventional surgical techniques. [0003] According to another aspect, the invention relates to an assembly further comprising positioning means for placing at least a part of an anastomotic device capable of bringing together a first tissue portion and a second tissue portion to...
