Abstract
A stretchable buttress assembly includes a planar fabric layer and a biocompatible adhesive layer. The planar fabric layer is configured to stretch along a stretch axis. The planar fabric layer includes extensible fibers and non-extensible fibers. The extensible fibers are arranged in a repeatable pattern. The extensible fibers are oriented along respective paths that are each parallel to the stretch axis. The non-extensible fibers are arranged in a repeatable pattern and engaged with the extensible fibers. The adhesive layer is applied to the planar fabric and is configured to removably adhere the planar fabric layer to an end effector of a surgical stapler.
Claims9
A stretchable buttress assembly for reinforcing the mechanical fastening of tissue by surgical staples that are deployable from a surgical stapler, the buttress assembly comprising:
- (a) a planar fabric layer having a first side and a second side opposite the first side, wherein the planar fabric layer is configured to stretch along a stretch axis, wherein the planar fabric layer comprises:
- (i) a plurality of extensible fibers arranged in a repeatable pattern, wherein the extensible fibers are oriented along respective paths that are each parallel to the stretch axis, and
- (ii) a plurality of non-extensible fibers arranged in a repeatable pattern and engaged with the extensible fibers;
- and
- (b) a biocompatible adhesive layer, wherein the adhesive layer is applied to the first side of the planar fabric and is configured to removably adhere the planar fabric layer to an end effector of a surgical stapler.
