Abstract
An endovascular sleeve which can be utilized to navigate a pair of guidewires to a bifurcated body passageway such that, once in place, the guidewires are substantially untwisted or untangled. This greatly facilitates delivery of the bifurcated stent to the bifurcated artery.
Claims36
An endovascular sleeve for delivering a pair of guidewires to a bifurcated body passageway of a patient, the sleeve comprising
- a first tubular passageway and a second tubular passageway fixed with respect to one another, each tubular passageway configured to deliver a respective one of the pair of guidewires;
- the first tubular passageway comprising a first distal end and a first proximal end, the second tubular passageway comprising a second distal end and a second proximal end;
- the first distal end extending distally beyond the second distal end to define a junction which is configured to abut against a crotch in the bifurcated body passageway of the patient, the second distal end being fixed to said first tubular passageway at said junction;
- and
- the second tubular passageway having a length such that the second proximal end extends from the patient.
