1. A medical device for open surgery, comprising:
- an elongate member having a proximal end and a distal end;
an elongate tubular member having a proximal end, a distal end, and a lumen therebetween adapted to receive the elongate member;
a filter slideably received within the lumen of the elongate tubular member, the filter having a generally conical shape having a base and an apex, the base being coupled to the elongate member, wherein an axis of the filter extends perpendicular to an axis of the elongate member; and
an obturator tip carried by the filter at the apex of the filter and shaped to rest against the distal end of the elongate tubular member when the filter is within the lumen of the elongate tubular member.

Abstract
An endoluminal device having an elongate tubular member and a filter slideably received within a lumen of the tubular member. An obturator tip is carried by the filter and shaped to rest against the distal end of the elongate tubular member when the filter is within the lumen of the tubular member. Methods of using the obturator and the introducer for introducing the filter into a vessel, such as an aorta, are also disclosed.

12. A method for open surgery, comprising the steps of:
-
providing an elongate member having a proximal end and a distal end, an elongate tubular member having a proximal end, a distal end, and a lumen adapted to receive the elongate member, a filter slideably received within the lumen, wherein the filter has a generally conical shape having a base and an apex, the base being coupled to the elongate member, and wherein an axis of the filter extends perpendicularly to an axis of the elongate member, and an obturator tip carried by the filter at the apex of the filter;
inserting the obturator tip and distal end of the elongate tubular member into a vessel;
advancing the filter and obturator tip beyond the distal end of the elongate tubular member; and
deploying the filter in the vessel. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
