Anvil Delivery Device Accessory

Abstract

An anvil delivery system includes an anvil assembly, a flexible tube, and a fitting. The fitting is coupled to the flexible tube and includes a body having a proximal end portion and a distal end portion and a tip disposed on the distal end portion. The proximal end portion of the body is adapted to attach the body to the flexible tube. The tip is configured for insertion into a body lumen. The anvil delivery system may further include a plurality of protrusions disposed on the proximal end portion of the body of the fitting.

       7 . The anvil delivery system of  claim 6 , wherein the anvil assembly include an anvil, the anvil pivotable with respect to the flexible tube. 
   
   
       8 . The anvil delivery system according to  claim 6 , further comprising a bore extending through the distal end portion to receive a suture. 
   
   
       9 . The anvil delivery system according to  claim 6 , further comprising an adapter configured to releasably secure the first end portion of the flexible tube to the anvil assembly. 
   
   
       10 . The anvil delivery system according to  claim 9 , further comprising a suture extending between the adapter and anvil assembly. 
   
   
       11 . A kit, comprising:
 a flexible tube having a distal end and an open proximal end;   an adapter configured to be releasably secured to the flexible tube;   a fitting configured to be attached to the flexible tube after the distal end of the flexible tube has been cut, the fitting having a body having a proximal end portion configured to attach to the flexible tube and a distal end portion.   
   
   
       12 . The kit according to  claim 11 , wherein the proximal end portion of the body is dimensioned to be supported within the flexible tube. 
   
   
       13 . The kit according to  claim 11 , wherein the distal end is configured for insertion into a body lumen. 
   
   
       14 . The kit according to  claim 11 , further comprising a plurality of protrusions disposed on the proximal end portion of the body, the plurality of protrusions being adapted to operatively attach the body of the fitting to the flexible tube. 
   
   
       15 . The kit according to  claim 11 , wherein the fitting includes a bore extending through the distal end portion of the body. 
   
   
       16 . The kit according to  claim 11 , further comprising an anvil assembly configured to be attach to the flexible tube. 
   
   
       17 . The kit according to  claim 12 , wherein the anvil assembly, the flexible tube, and the adapter are fastened together with a suture. 
   
   
       18 . The kit according to  claim 11 , further comprising a casing encompassing at least the adapter, the flexible tube, and the fitting. 
   
   
       19 . A method of performing a surgical procedure comprising:
 providing an anvil assembly having an anvil head and a flexible tube having a first end portion extending from the anvil assembly;   cutting a second end portion of the flexible tube, the second end portion being disposed on an opposite end of the tube from the first end portion;   attaching a fitting to the second end portion of the flexible tube, the fitting having an insertion tip; and   inserting the second end portion of the flexible tube into a body;   positioning the anvil assembly within the body using the flexible tube;   detaching the flexible tube from the anvil assembly while the anvil assembly is positioned within the body.   
   
   
       20 . The method of  claim 19 , wherein the fitting includes a bore to receive a suture and the inserting step includes the step of grasping the suture to pull the insertion tip to advance the fitting, flexible tube and anvil assembly.
