SYSTEMS AND METHODS FOR REMOVING OBSTRUCTIVE MATTER FROM BODY LUMENS AND TREATING VASCULAR DEFECTS
First Claim
1. A method for increasing flow of a body fluid through an obstructed body lumen, the method comprising:
- inserting a catheter system into the body lumen in a collapsed configuration, the system comprising (i) an outer shaft having a lumen, sidewall, and a longitudinal window in the sidewall, (ii) an inner shaft disposed within the lumen, and (iii) an expandable member having a first end coupled to the outer shaft and a second end coupled to the inner shaft through the window;
positioning the expandable member adjacent to a target region while in the collapsed configuration; and
expanding the expandable member from the collapsed configuration to an expanded configuration by relative movement of the outer shaft and the inner shaft.

Abstract
A catheter system can be used to remove obstructions, deliver implantable devices or substances, and/or restore flow through body lumens. The system can include an outer shaft having a lumen, sidewall, and a longitudinal window in the sidewall, an inner shaft disposed within the lumen, and an expandable member having a first end coupled to the outer shaft and a second end coupled to the inner shaft through the window. The expandable member can be positioned adjacent to a target region while in the collapsed configuration. The expandable member can be expanded to an expanded configuration by relative movement of the outer shaft and the inner shaft.

13. A method for increasing flow of a body fluid through an obstructed body lumen, the method comprising:
-
inserting a catheter system into the body lumen in a collapsed configuration, the system comprising a first component, a second component, and an expandable member having a first end coupled to the first component and a second end coupled to the second component; positioning the expandable member adjacent to a target region while in the collapsed configuration; and moving the expandable member to an expanded configuration by proximally withdrawing the first component relative to the second component. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
