Systems and methods for management of thrombosis
First Claim
1. A method for aspirating material from a patient comprising:
- providing an elongate tubular member having a distal end configured to be inserted into the vasculature of a subject, a proximal end configured to extend externally from the subject, and a lumen extending from the proximal end to the distal end, the lumen having a first diameter adjacent the distal end;
providing an aspiration catheter having a proximal end and a distal end and configured to be inserted through the lumen of the elongate tubular member, the aspiration catheter comprising;
a tubular aspiration member having a proximal end, a distal end, and an aspiration lumen extending between the proximal end and the distal end of the tubular aspiration member, the tubular aspiration member configured to at least partially extend out of the lumen of the elongate tubular member at the distal end of the elongate tubular member and into the vasculature of the subject;
an elongate support member coupled to the tubular aspiration member and extending between the proximal end of the aspiration catheter and the proximal end of the tubular aspiration member; and
at least one annular sealing member coupled to the tubular aspiration member and configured to seal against the first diameter of the lumen of the elongate tubular member;
placing the distal end of the elongate tubular member into the vasculature of the subject;
inserting the aspiration catheter into the lumen of the elongate tubular member;
extending the distal end of the tubular aspiration member out of the distal end of the elongate tubular member such that the distal end of the tubular aspiration member is adjacent a target area within the vasculature of the subject and the at least one annular sealing member is aligned with the first diameter of the lumen of the elongate tubular member; and
applying a vacuum from a vacuum source to the lumen of the elongate tubular member at the proximal end of the elongate tubular member such that material adjacent the target area is aspirated through the tubular aspiration member from its distal end to its proximal end and into the lumen of the elongate tubular member.

Abstract
A method for aspirating material from a patient includes providing an elongate tubular member having a lumen having a first diameter adjacent its distal end, providing an aspiration catheter including a tubular aspiration member having an aspiration lumen and configured to at least partially extend out of the lumen of the elongate tubular member, an elongate support member coupled to the tubular aspiration member, and at least one annular sealing member coupled to the tubular aspiration member and configured to seal against the first diameter, placing the distal end of the elongate tubular member into vasculature, inserting the aspiration catheter into the lumen of the elongate tubular member, extending the distal end of the tubular aspiration member out of the distal end of the elongate tubular member such that the at least one annular sealing member is aligned with the first diameter of the lumen of the elongate tubular member, and applying a vacuum to the lumen of the elongate tubular member at the such that material is aspirated through the tubular aspiration member and into the lumen of the elongate tubular member.
