US 2018/0021029 A1 · LAPAROSCOPIC PORT SITE CLOSURE TOOL

Abstract

A device is provided to assist in closing an incision through body tissue that comprises a tubular body sized for introduction through the incision and carrying a plurality of stabilizer elements at the distal end thereof. The stabilizer elements are configured to be deployed within the body cavity to engage the lowermost tissue layer. In one method, the device is pulled with the stabilizer elements deployed to retract the body tissue away from adjacent body structure. In another method, a plurality of needle tips carrying sutures are guided through the body tissue to a retention device at the ends of the stabilizer elements. With the needle tips captured in the retention devices, the device is withdrawn from the incision so that the sutures form ligatures that can be tied off to close the incision.

Dependent claims

A device for assisting in closure of an incision in tissue layers of a patient, the device comprising:

a cylindrical body defining a longitudinally extending side wall for introduction through the incision, the cylindrical body having a distal end portion, a proximal end portion, and a length between the distal end portion and the proximal end portion;
and
at least one wing element movably supported at the distal end portion, the at least one wing element being selectively movable between a retracted position to permit insertion of the cylindrical body through the incision, and a deployed position where the at least one wing element extends laterally away from the cylindrical body to permit contact with an interior surface of the tissue layers,
wherein the cylindrical body defines at least one guide channel extending from the proximal end portion to the distal end portion for directing a needle carrying a suture to an opening defined by the at least one wing element such that at least a portion of the suture passes through the opening of the at least one wing element.
