摘要：
A staple for attaching a sheet-like implantto tissue or bone may include first and second arms, andfirst and second flukes. In some embodiments, the firstarm has a proximal end and a distal end, and the secondarm has a proximal end and a distal end. A bridge extendsfrom the proximal end of the first arm to the proximal endof the second arm. The first fluke has a proximal endabutting the distal end of the first arm, and the first flukeextends distally from the first arm. The first fluke has alateral extent larger than a lateral extent of the first armand is mounted eccentrically thereto. The first fluke includesa proximal surface projecting at an outward anglein a proximal direction away from the distal end of thefirst arm to engage the tissue or bone when inserted therein.The second fluke has similar features. This arrangementcauses the first and second flukes to rotate in responseto a pullout force on the bridge. Methods for attachinga sheet-like implant to a target tissue are also disclosed.
