Percutaneous endovascular apparatus for repair of aneurysms and arterial blockages
First Claim
1. An endovascular apparatus comprising:
- a tubular sleeve having a central lumen with a cranial end portion longitudinally separated from a caudal end portion, the cranial end portion including a cranial end opening and the caudal end portion including at least one caudal end opening;
a first expandable attachment device having a first expandable attachment device circumference extending circumferentially around the cranial end portion of the tubular sleeve;
a second expandable attachment device having a second expandable attachment device circumference; and
at least one support column having cranial and caudal column ends separated by a column body, the caudal column end being attached to the first expandable attachment device and the cranial column end being attached to the second expandable attachment device, the column body extending longitudinally between the first and second expandable attachment devices to longitudinally space the second expandable attachment device entirely cranially apart from the first expandable attachment device;
wherein at least one support column contains an adhesive in an interior cavity of the column body, the support column including at least one aperture for selective release of the adhesive from the interior cavity.

Abstract
An endovascular apparatus is provided for treating the effects of vascular disease including aneurysms and arterial blockages using a percutaneous, minimally invasive technique. In one embodiment the endovascular apparatus includes a tubular sleeve having a cranial end, a first caudal branch, and a second caudal branch such that the tubular sleeve is shaped like an upside down “Y.” The apparatus further—includes at least one expandable attachment device attached to the tubular sleeve for securing the endovascular apparatus to an interior wall of a vessel. The at least one expandable attachment device includes a plurality of telescoping segments similar to the telescoping segments of a presentation pointer. Accordingly, during percutaneous insertion of the endovascular apparatus into a patient the attachment device can be collapsed into a small profile. Once positioned at the site of the aneurysm the telescoping attachment device can be expanded to hold the endovascular apparatus in place.
