摘要：
#$%^&*AU2010200618B220120621.pdf#####39 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 5 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 10 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.11/14 -fleS on
