Abstract
Abstract A method and device for efficiently and effectively stapling an opening in an anatomical structure such as veins, arteries, organs, and other body members within a living body is disclosed. The opening may be from a deliberately placed incision, as from an invasive surgical procedure, or caused by other damaging events. The device includes a stapling mechanism having a main body with a handle, a trigger for activating the staples, and a central passage through which a balloon catheter may pass. The balloon catheter supports the artery and helps position the stapling mechanism properly on the artery. Alternatively, the device may have a main body that has an inflatable member attached to it and extending from it. The main body provides a passage through which a pressurized media such as saline can be supplied to the inflatable member. In either case, the main body may advantageously include a flashback lumen through which blood or other fluid may flow as an indication of the position of the device within the anatomical structure.
