Fitting for receiving and fixing a sleeve for enforcing the end of a hollow organ

Abstract

A fitting for receiving and fixing at least one sleeve for enforcing an end of a hollow organ so that said end of the hollow organ can be connected with a further end of the hollow organ, the fitting having a cylindrically shaped body, said body being configured to receive and hold two sleeves with turned-over hollow organ ends so that inner sides of the hollow organ ends make contact with one another.

1 . A fitting for receiving and fixing at least one sleeve for enforcing an end of a hollow organ so that said end of the hollow organ can be connected with a further end of the hollow organ, the fitting comprising:
 a cylindrically shaped body, and   said body being configured to receive and hold two sleeves with turned-over hollow organ ends so that inner sides of the hollow organ ends make contact with one another.   
     
     
         2 . The fitting according to  claim 1 , wherein the body is completely or partially slit in a longitudinal direction in order to allow or to facilitate the insertion of the two sleeves. 
     
     
         3 . The fitting according to  claim 1 , wherein the body is a ring that is completely or partially slit in a longitudinal direction and comprises a fenestration that permits observation of the ends of the hollow organs introduced into the fitting. 
     
     
         4 . The fitting according to  claim 2 , wherein the fit of said sleeve for enforcing the end of the hollow organ and of the fitting for accommodating two sleeves allows a press fit, an interference fit or a push fit. 
     
     
         5 . The fitting according to  claim 1 , wherein the body has a curved profile or a U-profile along a longitudinal axis so as to encompass two sleeves with turned-over hollow organ ends over their entire lengths, wherein the inner sides of the hollow organ ends make contact with one another. 
     
     
         6 . The fitting according to  claim 1 , wherein the body is configured to receive and hold a sleeve having a cylindrical shape and being configured to be pushed over the end of the hollow organ and for turning-over the end of the hollow organ projecting from the sleeve around an end of the sleeve, wherein the sleeve has an adjustable diameter. 
     
     
         7 . The fitting according to  claim 1 , wherein the body is configured to receive and hold a sleeve that is formed by an expandable material mesh configured to allow adjustment of a diameter of the sleeve by application of an external pressure. 
     
     
         8 . The fitting according to  claim 7 , wherein the sleeve is composed of fine metallic or nonmetallic filaments forming a cylindrical mesh with an adjustable diameter. 
     
     
         9 . The fitting according to  claim 1 , wherein the body is configured to receive and hold a sleeve that is configured so that it reduces in diameter or collapses when a radial pressure is applied, and returns to its original diameter when the pressure is removed or to a reduced diameter if a reduced pressure is exerted. 
     
     
         10 . The fitting according to  claim 1 , wherein the body is configured to receive and hold a sleeve that comprises a region having a reduced diameter and at least one other region which comprises a larger diameter. 
     
     
         11 . The fitting according to  claim 10 , wherein a radial pressure is exerted on the sleeve region having a reduced diameter and wherein no pressure or less radial pressure is exerted on the at least one other sleeve region which comprises a larger diameter. 
     
     
         12 . The fitting according to  claim 10 , wherein the region having a reduced diameter includes one end of the sleeve where a hollow organ end is folded back on the sleeve, wherein the pressure is exerted by the folded back hollow organ end.
