Abstract
A combination medical device comprising a circular stapler instrument () and one or more portions of preformed buttress material () adapted to be stably positioned upon the staple cartridge () and/or anvil () components of the stapler () prior or at the time of use. Positioned buttress material(s) () are delivered to a tissue site where the circular stapler () is actuated to connect previously severed tissue portions. An embodiment of the invention allows tissue portions to be joined without the use of sutures. The buttress material () is made up of two regions, one of which serves primarily to secure the buttress material () to the stapler () prior to actuation, and one of which serves primarily to form the improved seal. The former region is severed and discarded upon activation of the circular stapler () to form anastomoses, while the remaining material secures and seals the newly connected tissue. Methods of use and preparation of the buttress material () are also described.
