Abstract:
1. A modular stent graft system comprising a first stent graft comprising a first tubular body of biocompatible graft material, a proximal end, a distal end and a first interface region having an internal surface and an external surface at the distal end; a first self-expanding locking stent secured to the internal surface of the first interface region, the first locking stent comprising a series of proximal apices and a series of distal apices, a proximal end having a first diameter and a distal end having a second diameter greater than the first diameter, wherein the first locking stent is secured to the internal surface of the first interface region only at the distal stent apices; a second stent graft comprising a second tubular body of biocompatible graft material, a proximal end, a distal end and a second interface region having an internal surface and an external surface at the proximal end configured to at least partially overlap with the first interface region; a second self-expanding locking stent secured to the external surface of the second interface region, the second locking stent comprising a series of proximal apices, a series of distal apices, a proximal end having a first diameter and a distal end having a second diameter greater than the first diameter, wherein the second locking stent is secured to the external surface of the second interface region only at the proximal stent apices; wherein the first locking stent is configured to receive the second locking stent in an interlocking relationship.
