Abstract

A surgical stapler includes a head in which a plurality of staples are stored. The head includes a facing surface. The stapler also includes an anvil having an anvil surface shaped and dimensioned for forming the staples upon actuation of the surgical stapler, the anvil including a facing surface opposed to the facing surface of the head for mating engagement therewith. The facing surface of the head is obliquely oriented relative to a longitudinal axis of the head creating an elliptical staple line when the head is brought into contact with anvil during actuation of the surgical stapler.

Description

technical field [0001] The present invention relates to surgical staplers for anastomosis. More particularly, the present invention relates to endoluminal surgical staplers that form an elliptical profile during an anastomosis. Background technique [0002] Surgical staplers have long been known in the surgical field as a quick and efficient method of joining or repairing tissue. Stapling has become an acceptable alternative to suturing. In some types of surgery, the use of surgical staples has become the preferred method of joining tissue, and specially configured surgical staplers have been developed for these applications. [0003] Endoluminal or circular staplers have been developed for use in the surgical procedure known as anastomosis. An example of an endoluminal surgical stapler for use in performing anastomoses is disclosed in US Pat. No. 5,104,025, which is incorporated herein by reference. [0004] Conventional endoluminal surgical staplers typically include a...
