Abstract
The present embodiments describe a multi-component endograft having a first endograft with first and second wall openings, a second endograft with a third wall opening, a third endograft with a fourth wall opening, where during an adjustment state the second and third endografts are independently adjustable, both vertically along a longitudinal axis and rotationally relative to the longitudinal axis, (1) while keeping the perimeter of the third wall opening primarily encompassed by the perimeter of the first wall opening and (2) while keeping the perimeter of the fourth wall opening primarily encompassed by the perimeter of the second wall opening.
Claims20
A multi-component endograft, comprising:
- a first endograft comprising,
- a first tubular main body portion having a first proximal end with a first proximal opening, a first distal end with a first distal opening, and a first lumen extending therebetween along a longitudinal axis,
- first and second wall openings through a wall of the first tubular main body portion and having first and second perimeters, respectively, in fluid communication with the first lumen;
- a second endograft comprising,
- a second tubular main body portion having a second proximal end with a second proximal opening, a second distal end with a second distal opening, and a second lumen extending therebetween,
- a third wall opening through a wall of the second tubular main body portion having a third perimeter in fluid communication with the second lumen;
- a third endograft comprising,
- a third tubular main body portion having a third proximal end with a third proximal opening, a third distal end with a third distal opening, and a third lumen extending therebetween,
- a fourth wall opening through a wall of the third tubular main body portion having a fourth perimeter in fluid communication with the third lumen;
- and
- wherein the first, second, and third endografts are constructed and dimensioned such that in an adjustment state where the second and third endografts are both within the lumen of the first endograft, the second and third endografts are independently adjustable, both vertically along the longitudinal axis and rotationally relative to the longitudinal axis, while keeping the third perimeter of the third wall opening primarily encompassed by the first perimeter of the first wall opening and while keeping the fourth perimeter of the fourth wall opening primarily encompassed by the second perimeter of the second wall opening.
