A new vascular Endostaple: a technical description.

Abstract

The purpose of this report is to describe a new vascular Endostapling system. The vascular Endostapling system can be passed through a 13F insertion sheath that is inserted through the femoral artery. An optical fiber and overlying Endostaple will penetrate a previously inserted endoprosthesis and the aortic wall at whatever points are desired. Once the optical fiber is withdrawn, the Endostaple assumes its preformed shape and acts like a through-and-through wire suture. As tissue ingrowth proceeds, the long-term security and stabilization of the coiled coil mechanism are likely to increase. We think Endostaples can be useful in preventing endograft migration and in treating endoleak at the site of the aortic neck-proximal endograft interface.
