Abstract
The present disclosure is directed to a branched endoprosthesis comprising a graft component and at least one support component. In various embodiments, the branched endoprosthesis comprises a body portion and a plurality of leg portions, wherein the legs are in an aligned configuration for ease of cannulation. In various embodiments, at least one leg is in an open configuration for ease of cannulation. Cannulation methods are also taught.
Claims20
A method comprising:
- providing a branched endoprosthesis comprising a body, a first leg, and a second leg;
- delivering the endoprosthesis to a position within a vessel in a delivery configuration;
- deploying the endoprosthesis to a partially deployed state;
- maintaining the first leg in alignment with the second leg with a restraint that restrains movement of the first leg relative to the second leg while the endoprosthesis is in the partially deployed state;
- cannulating the second leg while the restraint maintains alignment of the first leg with the second leg;
- and
- releasing the restraint between the first and second legs such that the first and second legs are free to angle apart.

A method comprising:
- providing an endoprosthesis that includes a body portion and a plurality of legs that are biased to be angled apart, the endoprosthesis having a removable restraint coupled thereto that overcomes the bias and aligns the plurality of legs;
- delivering the endoprosthesis to a position with a vessel while the the bias of the first and second legs is overcome by the removable restraint;
- partially deploying the endoprosthesis by removing a constraining sheath disposed about a first one of the plurality of legs;
- cannulating the first one of the plurality of legs after partially deploying the endoprosthesis and while the bias of the first and second legs remains overcome by the removable restraint;
- and
- removing the removable restraint such that the bias of the plurality of legs causes the plurality of legs to angle apart.
