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.
本发明公开了一种用于在组织部位内引起组织死亡的工具和方法。该工具包括一种介质,该介质带有一种光激活药物,当接受到特定
水平的超声能量时可被激活。该工具还包括一种导管,该导管的腔室与介质输送口相连,通过该输送口可以将光激活药物局部输送到组织部位。超声换能器被配置为传输足以穿透组织部位的超声能量
水平,以激活光激活药物。
