Abstract:
1. A catheter, comprising: an elongate tubular body with an exterior surface, wherein a distal end portion of said tubular body has an outer diameter of less than about 5 French for advancement through a small blood vessel, said tubular body defining a delivery lumen extending longitudinally therethrough and terminating in an exit port at a distal tip; a hypotube configured to be slidably received within said delivery lumen; a hollow cylindrical ultrasound radiating crystal coupled to a distal end portion of said hypotube, wherein said hypotube is positioned through the hollow cylindrical ultrasound radiating crystal, and wherein said hypotube is advanceable through said delivery lumen in said tubular body and out through said exit port for placement of said ultrasound radiating crystal at a treatment site; a potting material that covers at least a portion of (a) a radial surface of the ultrasound radiating crystal and (b) an end surface of the ultrasound radiating crystal, thereby forming a potted ultrasound radiating crystal; and a pair of wires extending longitudinally through an inner lumen in said hypotube for providing an electrical signal to said ultrasound radiating crystal.
