Devices for providing acoustic hemostasis |
摘要 |
Methods and apparatus for the remote coagulation of blood using high-intensity focused ultrasound (HIFU) are provided. A remote hemostasis method comprises identifying a site of internal bleeding and focusing therapeutic ultrasound energy on the site, the energy being focused through an intervening tissue. An apparatus for producing remote hemostasis comprises a focused therapeutic ultrasound radiating surface and a sensor for identifying a site of internal bleeding, with a registration means coupled to the radiating surface and the sensor to bring a focal target and the bleeding site into alignment. The sensor generally comprises a Doppler imaging display. Hemostasis enhancing agents may be introduced to the site for actuation by the ultrasound energy.
