Abstract:
1. A method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein, the method comprising: inserting a guidewire or crossing device into the vascular lumen; positioning a distal portion of the guidewire or crossing device in the vascular wall; advancing an intravascular device over the guidewire or crossing device, the intravascular device defining a tubular body and a lumen, and having a distal portion including a side port and lateral projections, wherein each of the lateral projections includes a delivery configuration and a deployed configuration, wherein the lateral projections are formed from a single tubular member and are completely external the lumen in both the delivery and the deployed configurations; positioning the distal portion of the intravascular device in the vascular wall; directing the lateral projections laterally within the vascular wall such that the lateral projections are in the deployed configuration; causing the intravascular device to assume an arbitrary one of two possible orientations relative to the vascular lumen, the two possible orientations comprising a first orientation in which the side port is directed toward the vascular lumen and a second orientation in which the side port is directed about 180 degrees away from the vascular lumen; advancing a distal end of a reentry device through the side port and determining which of the first orientation and the second orientation is the current orientation of the intravascular device; and advancing the distal end of the reentry device into the vascular lumen if it is determined that the current orientation of the intravascular device is the first orientation.
