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 adjacent the inner lumen wall.

Claims

1-18. -18. (canceled)

19. 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.

20. The endovascular apparatus of claim 19, wherein the caudal end portion of the tubular sleeve includes a first caudal branch laterally separated from a second caudal branch, the first and second caudal branches each including a branch opening oriented in a caudal direction.

21. The endovascular apparatus of claim 20, wherein at least one of the first and second caudal branches includes a branch expandable attachment device extending circumferentially therearound and attached thereto.

22. The endovascular apparatus of claim 19, wherein the caudal end opening includes a caudal end expandable attachment device extending circumferentially around the caudal end portion of the tubular sleeve.

23. The endovascular apparatus of claim 19, wherein the support column is a telescoping support column having a plurality of incrementally sized column segments in slideable contact with one another, and at least one selected column segment contains an adhesive in an interior cavity thereof, the selected segment including at least one aperture for selective release of the adhesive from the interior cavity.

24. 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; and

an expandable attachment device extending circumferentially around the cranial end portion of the tubular sleeve, the expandable attachment device including

a plurality of fixation components positioned about the perimeter of the expandable attachment device, and

a plurality of circumferentially extending arms, each arm being used to attach each fixation component to a circumferentially adjacent fixation component, and

at least one selected arm containing an adhesive in a cavity thereof, the selected arm including at least one aperture for selective release of the adhesive from the cavity.

25. The endovascular apparatus of claim 24, wherein the caudal end portion of the tubular sleeve includes a first caudal branch laterally separated from a second caudal branch, the first and second caudal branches each including a branch opening oriented in a caudal direction.

26. The endovascular apparatus of claim 25, wherein the expandable attachment device is a first expandable attachment device, and wherein at least one of the first and second caudal branches includes a branch expandable attachment device extending circumferentially therearound and attached thereto.

27. The endovascular apparatus of claim 26, wherein each branch expandable attachment device includes:

a plurality of fixation components positioned about the perimeter of the expandable attachment device, and

a plurality of circumferentially extending arms, each arm being used to attach each fixation component to a circumferentially adjacent fixation component, and

at least one selected arm containing an adhesive in a cavity thereof, the selected arm including at least one aperture for selective release of the adhesive from the cavity.

28. The endovascular apparatus of claim 24, wherein the expandable attachment device is a first expandable attachment device, and wherein the caudal end opening includes a caudal end expandable attachment device extending circumferentially around the caudal end portion of the tubular sleeve.

29. The endovascular apparatus of claim 28, wherein the caudal end expandable attachment device includes:

a plurality of fixation components positioned about the perimeter of the expandable attachment device, and

a plurality of circumferentially extending arms, each arm being used to attach each fixation component to a circumferentially adjacent fixation component, and

at least one selected arm containing an adhesive in a cavity thereof, the selected arm including at least one aperture for selective release of the adhesive from the cavity.

30. The endovascular apparatus of claim 24, wherein the arms of the expandable attachment device are selectively collapsible in the circumferential direction to selectively and reversibly reduce a total circumference of the expandable attachment device from an expanded apparatus condition to a collapsed apparatus condition.

31. The endovascular apparatus of claim 27, wherein the arms of the branch expandable attachment device are selectively collapsible in the circumferential direction to selectively and reversibly reduce a total circumference of the expandable attachment device from an expanded apparatus condition to a collapsed apparatus condition.

32. The endovascular apparatus of claim 29, wherein the arms of the caudal end expandable attachment device are selectively collapsible in the circumferential direction to selectively and reversibly reduce a total circumference of the expandable attachment device from an expanded apparatus condition to a collapsed apparatus condition.

33. The endovascular apparatus of claim 24, wherein at least one circumferentially extending arm of the expandable attachment device is a telescoping arm having a plurality of segments in slideable contact with one another, and at least one selected segment contains an adhesive in an interior cavity thereof, the selected segment including at least one aperture for selective release of the adhesive from the interior cavity.
