System and method for positioning a stent graft

A stent graft can be held in place on the outside of the thoracic arch by a hypodermic needle tube which passes through a bore of the stent graft and back to the user. A center tube tethered to the stent graft at an end distal to the user is employed to hold the stent graft within the pulsatile bloo...

Zusammenfassung:	A stent graft can be held in place on the outside of the thoracic arch by a hypodermic needle tube which passes through a bore of the stent graft and back to the user. A center tube tethered to the stent graft at an end distal to the user is employed to hold the stent graft within the pulsatile blood flow, preventing the stent graft from collapsing during deployment. The position of both the hypodermic needle tube and the center tube can be controlled by the user by a control handle.
