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. The buttress material is retained and provides an improved seal between the joined tissue sections. 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 an anastomoses. Methods of use and preparation of the buttress material are also described.
