Abstract
Exemplary embodiments of the present invention comprise a stent graft having a first section and a second section, wherein the first section comprises a first longitudinal profile and a first flow lumen and the second section comprises a second longitudinal profile and a second flow lumen. In exemplary embodiments, a hinged connection between the first and second sections is structurally and/or materially configured to isolate or otherwise not transfer bending forces between the first and second sections.
Claims18
An endoprosthesis comprising:
- a single, continuous graft component having an uninterrupted outer surface combined with a plurality of support components, the combination comprising:
- a first section having a first longitudinal profile and a first flow lumen;
- a second section having a second longitudinal profile and a second flow lumen;
- and
- a hinged connection free of the support components and between the first section and the second section;
- wherein the first flow lumen and the second flow lumen are opened during a deployment of the endoprosthesis and remain open during actuation of the hinged connection such that the first longitudinal profile is bent with respect to the second longitudinal profile.
An endoprosthesis comprising:
- a single, continuous graft component combined with a plurality of support components, the combination comprising:
- a first section having a first longitudinal profile and a first flow lumen;
- a second section having a second longitudinal profile and a second flow lumen;
- and
- a hinged connection between the first section and the second section, the hinged connection isolating bending forces between the first and second sections;
- wherein the first flow lumen and the second flow lumen are opened during a deployment of the endoprosthesis and remain open during actuation of the hinged connection such that the first longitudinal profile is bent with respect to the second longitudinal profile, and wherein the first and second flow lumens exhibit diameter differential and adjacent ends of the first and second flow lumens telescope relative to one another.
A method for maintaining flow lumens of an endoprosthesis substantially open comprising:
- deploying an endoprosthesis at a treatment site, the treatment site comprising a turn and the endoprosthesis comprising:
- a single, continuous graft component having an uninterrupted outer surface combined with a plurality of support components, the combination comprising:
- a first section having a first longitudinal profile and a first flow lumen;
- a second section having a second longitudinal profile and a second flow lumen;
- and
- a hinged connection free of the support components and between the first section and the second section;
- wherein the first flow lumen and the second flow lumen are kept open when the hinged connection is actuated about the turn.
