    摘要： Methods and devices for separating plaque from vessel walls using everting membranes. Everting tubes disposed on catheters are used in one embodiment of the invention to separate plaque from blood vessel walls. One embodiment of the invention utilizes a single everting membrane including a fixed portion, a leading edge, and an advancing portion. The everting tube can have an interior which can be pressurized to propel the everting tube distal edge distally onward, so as to separate the plaque from the vessel inner wall. One device has double everting membranes fixedly attached to a tubular member and having facing advancing membrane portions which may be proximally fixed relative to one another, but are preferably both free to travel distally. The outermost tube can be laid down over the vessel inner wall and the innermost tube laid down over the plaque, with the advancing surfaces of each everting membrane facing each other. Fluid can be supplied under pressure to fill the interior of the everting tubes and thereby distally advance the tube leading edges. The present invention may be used in conjunction with distal emboli capturing filter or distal occlusion devices.

    摘要： A catheter assembly is disclosed. This assembly may include a first elongate member having an internal lumen and a distal portion, a second elongate member, slidable within the first elongate member, and a spacer positioned between the second elongate member and the first elongate member. In this example, the spacer may be positioned at bendable portions of the first elongate member and the second elongate member such that the spacer maintains a substantially uniform spacing between the second elongate member and the first elongate member when the first elongate member and the second elongate member are in a curved orientation.
