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.

Abstract: An ultrasound system has an ultrasound transducer having a transducer housing and a horn provided at the distal end of the transducer housing, an ultrasound transmission member, a sonic connector that is connected to the horn and the proximal end of the ultrasound transmission member, and a catheter knob having a proximal end that is coupled to the distal end of the transducer housing. The catheter knob has a proximal bore that houses the sonic connector. The system also includes a nesting piece that is retained inside the proximal bore of the catheter knob. The nesting piece can be moved from a first position where the sonic connector is received inside the nesting piece to a second position where the sonic connector is separated from the nesting piece when ultrasound energy is being propagated through the ultrasound transmission member.

Abstract: An ultrasonic system includes an ultrasound transducer housing, an ultrasonic catheter, and a transducer mechanism. The ultrasound transducer housing contains a transducer horn configured to be connected to a signal generator. The ultrasonic catheter includes an ultrasound transmission member having a proximal end and disposed in the lumen, a sonic connector that connects the proximal end of the ultrasound transmission member with the transducer horn, a control ring, and a nesting piece configured to selectively receive the sonic connector. The control ring is operatively coupled to the nesting piece to move the nesting piece. The transducer mechanism is configured to move from a first position to a second position, and wherein the transducer mechanism is configured such that movement of the transducer mechanism from the first position to the second position engages the control ring on the catheter to move the nesting piece.

Abstract: Ultrasound catheter devices and methods provide enhanced disruption of blood vessel obstructions. Generally, an ultrasound catheter includes an elongate flexible catheter body with one or more lumens. An ultrasound transmission member or wire extends longitudinally through the catheter body lumen and, in many embodiments, a guide wire tube also extends through the same lumen. A distal head is fixed to or otherwise mechanically coupled with the distal end of the ultrasound transmission member or wire and is positioned adjacent the distal end of the catheter body. Although the distal end of the catheter body overlaps the distal head, the distal head is not directly affixed to the distal end of the catheter body. Thus, the distal tip may move freely, relative to the distal end of the catheter body when ultrasonic energy is applied through the ultrasound transmission member. Such a freely floating distal head enhances the efficiency of an ultrasound catheter, enabling the catheter to ablate calcific occlusions and increasing the useful life of the ultrasound transmission member and catheter.
