Abstract
The present disclosure is directed to a branched endoprosthesis comprising a graft component and at least one support component.

In various embodiments, at least one leg is in an open configuration for ease of cannulation. Cannulation methods are also described.
Claims20
A medical device comprising:
- a stent graft including a graft component and a support component, the stent graft having a body portion, a first leg, and a second leg, wherein the first leg and the second leg are structurally biased to angle apart from one another;
- and
- a restraint aligning the first and second legs to couple together and maintain alignment of the first and second legs by temporarily overcoming the bias to assist in cannulation of the second leg during deployment of the stent graft, wherein the restraint is configured to be removed after deployment such that first and second legs are free to angle apart from one another.
A medical device comprising:
- a stent graft having a graft component and a support component, the stent graft having a body portion, a first leg and a second leg, the stent graft having a collapsed configuration for endoluminal delivery and an expanded configuration larger than the collapsed configuration;
- a removable restraint having a first portion and a second portion extending from the first portion;
- and
- an outer sheath for releasably retaining the stent graft toward the collapsed configuration, the outer sheath having opposite sides releasably held together by the first portion of the removable restraint;
- wherein
- the second portion of the removable restraint extends between the first and second legs to couple together and maintain alignment of the first and second legs as the first portion is actuated to release the opposite sides of the outer sheath.
