摘要： A catheter device incorporating combined ultrasound ablation and balloon dilation components. The catheter device generally comprises an elongate catheter body having proximal and distal ends and an outer surface. Disposed on the outer surface of the catheter body is a dilation balloon. At least one balloon inflation lumen fluidly connects the proximal end of the catheter body to the dilation balloon to permit injection of inflation fluid into the dilation balloon. Extending longitudinally through the catheter body is an ultrasound transmission member having a proximal end and a distal end, with the proximal end being connectable to an ultrasound transducer such that ultrasonic energy will pass through the ultrasound transmission member to the distal end thereof. In alternative embodiments of the present invention, there are provided catheter devices incorporating combined ultrasound ablation and laser ablation components as well as combined ultrasound ablation and atherectomy ablation components.

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.

摘要翻译： 用于将超声换能器附接到超声导管的连接器具有形成在超声换能器上的支撑构件，用于支撑设置在超声导管近端的导管联接器的至少一部分。 支撑构件优选地包括可滑动地设置在超声换能器上的套环，以便从非支撑位置移动，其中套环邻近导管联接设置到支撑位置，其中套环围绕并与导管联接器接合。 支撑导管联接件的至少一部分通过减小施加到其近端的机械应力来缓解超声传输构件断裂的发生。
