Abstract
A system for treating a vascular region includes an elongate catheter shaft having a distal end region, with an inner lumen formed in the elongate shaft and a fluid delivery lumen formed in the elongate shaft adjacent to the inner lumen. A treatment core is disposable within the inner lumen, and has a plurality of ultrasound transducers that are adapted to move between a straight configuration and a helical configuration and to provide constructive interference when in the helical configuration.
Claims20
A system for treating a vascular region, the system comprising:
- an elongate catheter shaft having a distal end region, the elongate catheter shaft defining an inner lumen extending through the elongate catheter shaft and a fluid delivery lumen extending adjacent to the inner lumen;
- and
- a treatment core disposed within the inner lumen, the treatment core including a plurality of ultrasound transducers that are adapted to provide constructive interference.
An ultrasonic catheter system, comprising:
- a multi-lumen catheter shaft having a central lumen and a plurality of fluid delivery lumens;
- and
- an ultrasound catheter core disposed within the central lumen, the ultrasound catheter core including a plurality of ultrasound transducers adapted to move between a straight configuration and a helical configuration;
- wherein the plurality of ultrasound transducers are adapted to provide constructive interference when in the helical configuration;
- and
- wherein the central lumen is adapted to allow for a cooling media to pass therethrough when the ultrasound catheter core is disposed within the central lumen.
A system for treating a vascular region, the system comprising:
- an elongate catheter shaft having a distal end region, the elongate catheter shaft defining an inner lumen extending through the elongate catheter shaft and a fluid delivery lumen extending adjacent to the inner lumen;
- and
- a treatment core disposed within the inner lumen, the treatment core including two or more ultrasound radiating members, each of the two or more ultrasound radiating members adapted to provide constructive interference when in the helical configuration.
