Beschreibung
Zusammenfassung:	The invention provides an endovascular torquing device for a rotational fastener and a system and method for endovascular delivery of a rotational fastener to a treatment site within a patient. The torquing device comprises a flexible body portion having a guidewire lumen extending longitudinally there through. A coupling portion formed on a distal end of the body portion interfaces with a rotational fastener positioned within a vessel. The system comprises a guide catheter, at least one guidewire, at least one rotational fastener disposed on the guidewire, and a torquing device. The guide catheter is positioned adjacent to a treatment site, and the rotational fastener and guidewire are delivered through the guide catheter to the treatment site. The torquing device, which has a guidewire lumen extending longitudinally through at least a portion of the device, tracks over the guidewire to engage and rotate the fastener.
