Abstract
A kit and method for causing tissue death within a tissue site is disclosed. The kit includes a media with a light activated drug activatable upon exposure to a particular level of ultrasound energy. The kit also includes a catheter with a lumen coupled with a media delivery port through which the light activated drug can be locally delivered to the tissue site. The ultrasound transducer is configured to transmit the level of ultrasound energy which activates the light activated drug with sufficient power that the ultrasound energy can penetrate the tissue site.
Claims20
A kit for causing tissue death within a tissue site, comprising:
- a media including a light activated drug activatable upon exposure to a sufficient level of ultrasound energy;
- and
- a catheter having an elongated catheter body with at least one axial lumen therethrough, the catheter comprising,
- at least one ultrasound assembly coupled to the elongated catheter body, comprising at least one ultrasound transducer coupled to an energy source, wherein the at least one ultrasound transducer generates the sufficient level of ultrasound energy;
- at least one temperature sensor located adjacent to the at least one ultrasound transducer, wherein the at least one temperature sensor provides a measurement of a temperature adjacent to the at least one ultrasound transducer;
- and
- at least one media delivery port in fluid communication with the at least one axial lumen for delivery of the media.
