Abstract
A stent graft provides for a fenestration to be created by a side branch fenestration creation device. A kit comprises a side branch fenestration creation device and a stent graft in which a fenestration may be created thereby.
Claims15
A method for forming a fenestration through a stent graft at a location where a main vessel in which said stent graft is placed branches into a side branch vessel, said method including:
- c. placing a side branch vessel stent in said side branch vessel so that at least a portion of said side branch vessel stent protrudes into the lumen of said main vessel;
- and
- d. deploying the stent graft in the main vessel, so that:
- i. at least said portion of the side branch vessel stent punctures the stent graft from the outside at the location where the main vessel branches into the side branch vessel;
- or
- ii. the side branch vessel stent marks the location where the fenestration is to be formed, so that additional means may be inserted or may in advance have been inserted to aid in the creation of the fenestration.
A method for treating a medical condition in a main vessel that is in close proximity of the branching of the main vessel to a side branch vessel, including the following steps:
- a) placing a side branch vessel stent in the side branch vessel, so that at least a portion of said side branch vessel stent protrudes into the lumen of the main vessel;
- and
- b) deploying a stent graft in the main vessel,
- whereby either:
- i) the stent graft is punctured by the side branch vessel stent from the outer side of the stent graft;
- or
- ii) a puncture point is marked in the stent graft by the side branch vessel stent and additional means are used to aid in puncturing the stent graft at the puncture point.
A stent graft in which a fenestration is created, from the outside, by the side branch vessel fenestration creation device once the stent graft is deployed in an artery.
