A device for assisting in anastomosis of tubular structures. The basic device has a generally cylindrical shape with a pair of insertion arms and a central depression that provides a space for the needle to move through within the tubular structures while simultaneously providing support so that the suture needle thrust does not collapse the tubular structure wall. The depression may be configured to guide the path of the needle. A bridge connects the arms and prevents the needle from inadvertently coming in contact with the wall opposite that of the wall being sutured. The method includes an initial suture to join the sutures, inserting the device into the openings of the two structures, placing sutures in the walls adjacent to the depression, optionally rotating the device so the depression is aligned with each suture as it is being placed, removing the device, and tightening the sutures to complete the anastomosis.

Device and method for the surgical anastomasis of tubular structures

A device for assisting in anastomosis of tubular structures. The basic device has a generally cylindrical shape with a pair of insertion arms connected by a bridge and two or more depressions that provide space for the needle to move through within the tubular structures. The device aids in preventing the needle from inadvertent contact with the wall opposite that of the wall being sutured. The method includes an initial suture to join the structures, inserting the device into the openings of the two structures, placing sutures in the walls adjacent to a depression, optionally rotating the device so one of the depressions is aligned with each suture as it is being placed, removing the device, and tightening the sutures to complete the anastomosis.
