Device and method for loading a luminal graft for endoluminal delivery
View Patent ↗An endoluminal graft is wrapped axially upon itself to form a low profile, which facilitates endoluminal delivery. Apparatus and systems for making and using such grafts are also disclosed.
1. A rolled graft and a delivery system, comprising a generally tubular graft flattened against itself and rolled onto itself into a cylindrical configuration, wherein said graft includes a larger diameter main section and two smaller diameter sections that terminate the main section at an axial end of said larger diameter section, wherein the two smaller diameter sections are both disposed within the terminated axial end of the main section to enable a length of said rolled graft to be shortened during delivery by the delivery system inside a body lumen, in combination with an expansion element disposed axially within said rolled graft, further comprising a temporary covering surrounding and restraining said graft in said cylindrical configuration, wherein said temporary covering is configured to be released when the rolled graft is within the delivery system.
2. The rolled graft of claim 1 further comprising an aperture extending along an axis of said cylindrical rolled graft.
3. The rolled graft of claim 1 wherein said graft is rolled onto an axial member.
4. The rolled graft of claim 1 wherein said temporary covering is absorbed after delivery into a body lumen.
5. A rolled graft and a delivery system, comprising a generally tubular graft flattened against itself and rolled onto itself into a cylindrical configuration, wherein said graft includes a larger diameter main section and two smaller diameter sections that terminate the main section at an axial end of said larger diameter section, wherein the two smaller diameter sections are both disposed within the terminated axial end of the main section to enable a length of said rolled graft to be shortened during delivery by the delivery system inside a body lumen, further comprising a temporary covering surrounding and restraining said graft in said cylindrical configuration, wherein said temporary covering is configured to be dissolved or absorbed when the rolled graft is within the delivery system.
