Ultrasound assembly for use with light activated drugs

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 an ultrasound transducer that 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. The method includes providing the media comprising a light activated drug, delivering the media systematically into a patient's body, providing sufficient time for the light activated drug to localize within the tissue site, and directing ultrasound energy to the light activated drug within the tissue site to thereby activate the light activated drug.

1 . A method for treating a tissue site, comprising:
 providing an aqueous solution comprising a light activated drug;   delivering systematically the aqueous solution into a patient's body;   providing sufficient time for the light activated drug to localize within the tissue site; and   directing ultrasound energy to the light activated drug within the tissue site to thereby activate the light activated drug.
