Abstract

Universal endovascular grafts are provided for evaluation and repair of damaged or aneurismal blood vessels. More particularly, the present invention relates to universal fenestrated and universal branched endografts for repair of blood vessels with branches, methods for implanting the endografts in the vessel and for making connection with one or more branches. The universal fenestrated endografts have a body with a first end, a second end, a first wall, a second wall, and an interior passage or lumen. The body further includes openings in communication with the passage at the first and second ends and one or more lateral fenestrations in communication with the lumen. The body further has a necked portion between the ends and a cannulation member. The universal branched endografts have a tubular body with a main lumen and four branch lumens. A large branch extends from the body. The four lumens are positioned about a circumference of the tubular body.

Core Innovation

The invention relates to universal endovascular grafts for off-the-shelf repair of aneurysmal or damaged vessels that include branches. A universal fenestrated endograft includes an expandable tubular body extended along a longitudinal axis, with a first end and a second end and an interior passage between an internal surface and an external surface. The body includes a first opening and a second opening in communication with the interior passage at the first end and the second end, and the first opening and the second opening are substantially transverse to the longitudinal axis.

The universal fenestrated endograft further includes a universal fenestration in communication with the interior passage and between the first end and the second end. Three independent cannulation members extend from the universal lateral fenestration, and each independent cannulation member engages an internal surface of the body at an attachment point. Each independent cannulation member includes a first orifice and a second orifice defining a length therebetween, and the first and second orifices of each independent cannulation member are disposed within the interior passage.

In described embodiments, universal sizing and orientation concepts are emphasized for the universal fenestration and corresponding cannulation members, including selective internal and external orifice geometry such as flared orifices and multiple cannulation members associated with a single universal fenestration. The disclosure also describes universal branched endografts having a tubular main body with a main lumen and multiple radially distributed branch lumens, including a large branch, with the branch lumens sized and stacked within the main cylinder to connect to target branch arteries.

Claims Coverage

The independent claim identified is directed to a universal fenestrated endovascular graft with three independent cannulation members extending from a universal lateral fenestration, where the cannulation members have first and second orifices disposed within the interior passage and engage an internal surface at attachment points. The independent claim includes multiple inventive features centered on the expandable body, transverse end openings, a universal fenestration, and the three specific cannulation-member structures.

Across the identified inventive features, the claim coverage centers on an expandable endovascular graft body with transverse openings, a universal fenestration, and three independent cannulation members extending from the universal fenestration. The cannulation members engage the internal surface at attachment points and include first and second orifices disposed within the interior passage, thereby defining a cannulation length within the graft.
