Abstract:
1. A method of facilitating vascular treatment via a vascular wall defining a vascular lumen, the method comprising: inserting a first intravascular device into the vascular lumen, the first intravascular device including an elongate member defining a device lumen, the first intravascular device having a distal intramural portion with expandable lateral projections, wherein each lateral projection, when in an expanded state, defines a concave shape facing the vascular lumen and extending from a periphery of the lateral projection furthest from the elongate member to a side of the elongate member between a proximal end and a distal end of the lateral projection, and wherein the lateral projection, when in the expanded state, includes structure at the proximal end of the lateral projection contacting the elongate member, at the distal end of the lateral projection contacting the elongate member, and at a point between the proximal and distal ends contacting the elongate member, wherein the lateral projection includes a portion located radially away from the elongate member at a location between the proximal end and the point between the proximal and distal ends; positioning the intramural portion in the vascular wall; and moving the intramural portion within the vascular wall in a circumferential direction.
