Abstract
An ultrasonic catheter includes a body and an ultrasound transmission member disposed in the body. A head is coupled to the ultrasound transmission member, wherein a gap separates the head from a body distal end. A guidewire tube extends through the body and the head. A proximal end connector assembly includes a hub and an absorber member. The hub has a bore coupled to and in fluid communication with the body. The absorber member is disposed within the bore around the ultrasound transmission member. A sonic connector is disposed between the ultrasound transmission member and a separate generator.
Claims20
An ultrasonic catheter, comprising:
- a body having a body distal end and a catheter body lumen, the catheter body lumen defined by an interior wall;
- an ultrasound transmission member disposed in the body;
- a head coupled to the ultrasound transmission member, wherein a gap separates the head from the body distal end;
- an anchor member connected to the head and the interior wall of the body;
- a guidewire tube extending through the body and the head;
- and
- a proximal end connector assembly comprising:
- a hub with a bore coupled to and in fluid communication with the body;
- an absorber member disposed within the bore around the ultrasound transmission member;
- and
- a sonic connector disposed between the ultrasound transmission member and a separate generator.
An ultrasonic catheter, comprising:
- a body;
- a side aperture disposed in the body;
- an ultrasound transmission member disposed in the body having a distal tapered region and a polymeric coating;
- a head coupled to the ultrasound transmission member, wherein a gap separates the head from a body distal end, wherein the distal tapered region of the ultrasound transmission member is proximal of the head;
- an anchor member connected to the head and connected inside the body adjacent the distal tapered region;
- a proximal end connector assembly comprising:
- a hub with a bore coupled to and in fluid communication with the body;
- an absorber member disposed within the bore around the ultrasound transmission member;
- and
- a sonic connector disposed between the ultrasound transmission member and a separate generator,
- wherein the ultrasound transmission member extends proximally from the body through the bore, and the generator produces vibrations between 20 kHz and 40 kHz;
- and
- a guidewire tube extending through the body and the head and connected inside the body.
