Methods and devices for providing acoustic hemostasis

A method for producing remote hemostasis within a patient body, the method comprising:

• identifying a site at which it is desired to promote hemostasis;
• targeting a therapy region adjacent to the site;
• generating focused therapeutic ultrasound energy;
• and
• applying the focused therapeutic ultrasound energy from a radiating surface to a target within the therapy region.

A method for producing remote hemostasis within a patient body, the method comprising:

• identifying a site at which it is desired to promote hemostasis;
• introducing an ultrasound hemostasis enhancement agent to the site;
• generating and emitting therapeutic ultrasound energy from a radiating surface;
• and
• focusing the emitted therapeutic ultrasound energy to activate the hemostasis agent adjacent to the site.

An apparatus for producing remote hemostasis comprising:

• a radiating surface which applies focused therapeutic ultrasound energy to a target volume to produce remote hemostasis, the target volume being separated from the radiating surface;
• a sensor which identifies a site at which it is desired to induce hemostasis;
• and
• a registration mechanism coupled to the sensor and the radiating surface to align the target volume and the site.

An apparatus for producing remote hemostasis comprising:

• a pulsed ultrasound imaging transducer which images a site at which it is desired to promote hemostasis;
• an ultrasound radiating surface which focuses therapeutic energy at a target volume to produce remote hemostasis;
• and
• a display coupled to the imaging transducer and to the radiating surface, the display indicating the relative positions of the target volume and the site at which it is desired to promote hemostasis.
