ABSTRACT:
A medical stapling device in which open staples are moved along a track between two grooved rails by a drive member having spaced lugs. Upon activation of the device, the lugs are moved into engagement with the staples and advance them along the track so that the leading staple will be formed around an anvil at the end of the track and can suture living tissue adjacent the anvil. The portions of the staple that enter the tissue are smoothly curved so that they will enter like a surgeon's needle and provide a predetermined amount of gathering of the tissues, and the closed staple is shaped so that its maximum inner dimension is parallel to its central portion to restrict rotation of the staple due to tension across the suture.
