First Claim
1. A catheter device insertable into a body lumen and incorporating combined ultrasound ablation and balloon dilation apparatus, said device comprising:
- an elongate catheter body having a proximal end, a distal end and an outer surface;
a dilation balloon disposed on the outer surface of said catheter body;
at least one balloon inflation lumen fluidly connecting the proximal end of said catheter body to said dilation balloon to permit injection of inflation fluid into said dilation balloon; and
an ultrasound transmission member extending longitudinally through said catheter body, said ultrasound transmission member having a proximal end and a distal end, the proximal end of said ultrasound transmission member being connectable to an ultrasound transducer such that ultrasonic energy will pass through said ultrasound transmission member to the distal end thereofsaid ultrasound transmission member being connected to the distal end of said catheter body such that the distal end of the catheter body will undergo ultrasonic vibratory movement concurrently with said ultrasound member.

Abstract
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.
