Abstract
An endovascular stapler for securing an endograft to a vessel is disclosed. The stapler includes a staple housing adapted for storing at least one staple therein, the staple housing having an exit area for discharge of the at least one staple therethrough, an actuating assembly adapted for discharging the at least one staple through the exit area, and a displacement mechanism in operative association with the staple housing near the exit area. The displacement member is operative for pushing the exit area against the endograft when discharging the at least one staple therethrough. The discharged staple forms a plurality of opposed loops connected by a central element upon discharge. Also disclosed are staples and displacement mechanisms adapted for use with surgical instruments such as the present endovascular staplers. The staples may be formed from memory metal or other metal. The displacement mechanisms disclosed include balloons and rigid offsetting devices.
