摘要： A connector for attaching an ultrasound transducer to an ultrasound catheter has a support member formed on the ultrasound transducer for supporting at least a portion of a catheter coupling which is disposed at the proximal end of ultrasound catheter. The support member preferably comprises a collar slideably disposed upon the ultrasound transducer so as to move from a non-supporting position wherein the collar is disposed adjacent the catheter coupling to a supporting position wherein the collar is disposed around and engages the catheter coupling. Supporting at least a portion of the catheter coupling mitigates the occurrence of ultrasound transmission member breakage by reducing mechanical stress applied to the proximal end thereof.

摘要： 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.

摘要： 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.

摘要： An ultrasonic angioplasty device includes a catheter and a connector assembly for interconnecting an ultrasound transmission member to an ultrasound transducer. A rotation control device is provided that prevents the ultrasound transmission member from rotating relative to the catheter. Rotation is prevented by a fastener aligning the connector assembly with the elongated catheter body, or a key member that fits in a correspondingly shaped slot in a proximal shaft portion of the catheter, for preventing rotation of the connector assembly relative to the catheter.
