Abstract:
1. An intravascular laser catheter configured for laser ablation, comprising: a cylindrical outer electrode arranged on an outer surface of the intravascular laser catheter; a cylindrical inner electrode arranged within at least a portion of the cylindrical outer electrode; a strain sensitive material arranged between the cylindrical outer electrode and the cylindrical inner electrode; at least three electrical separators arranged in the strain sensitive material configured to spatially separate the cylindrical outer electrode, the cylindrical inner electrode, and the strain sensitive material, wherein the spatially separated cylindrical outer electrode, the cylindrical inner electrode and the strain sensitive material are configured as at least three separate pressure sensors and configured to provide spatial resolution of a pressure distribution during a laser ablation procedure; an inner lining creating an inner lumen, wherein the inner lining is disposed radially inward of the cylindrical inner electrode; and a plurality of optical fibers arranged between the inner lining and the cylindrical inner electrode.
