Abstract:
1. A stent-graft delivery system comprising: an outer tubular shaft having a proximal shaft segment attached to a distal shaft segment having a tubular textile component consisting of a fabric or cloth for flexibility, a distal end of the proximal shaft segment being attached to a proximal end of the tubular textile component by an attachment mechanism, wherein the proximal shaft segment is of a polymeric tubing that has a substantially greater resistance to bending than the tubular textile component and wherein the tubular textile component is non-compliant; an inner shaft that extends through an entire length of the outer tubular shaft; a distal tip component attached to the inner shaft, wherein a hub component is attached to a distal segment of the tubular textile component to provide radial support thereto, the hub component having an inner diameter that is sized to receive a proximal end of the distal tip component, and wherein the hub component includes a polymeric inner support tube and a polymeric outer support tube between which the distal segment of the tubular textile component is disposed; and a self-expanding stent-graft positioned around a distal portion of the inner shaft and constrained by the tubular textile component in a compressed delivery configuration, wherein retraction of the outer tubular shaft proximally slides the tubular textile component over the stent-graft to expose and deploy the stent-graft.
