1. A method for removing blood clots from a patient'"'"'s intracranial space using ultrasound energy, the method comprising:
- forming at least one aperture in the patient'"'"'s skull;
advancing an ultrasound device having a visualization feature through the aperture to a target location within the intracranial space;
transmitting ultrasound energy at frequencies between 1 KHz and 20 MHz from the ultrasound device; and
removing blood clots outside the patient'"'"'s head.

20. A method for removing blood clots from a patient'"'"'s intracranial space caused by hemorrhage, comprising the step of advancing an ultrasound device into the patient'"'"'s head, identifying blood clots with a visualization feature, transmitting ultrasound energy at frequencies between 1 KHz and 20 MHz, and removing blood clots outside the head.
- 21. A method for removing tissue from a patient'"'"'s intracranial space comprising the step of advancing an ultrasound device into the patient'"'"'s head, identifying tissue to be removed using a visualization feature, transmitting ultrasound energy at frequencies between 1 KHz and 20 MHz, and removing tissue outside the head.

23. A method for removing tissue from a patient'"'"'s intracranial space comprising the step of advancing a visualization device into the patient'"'"'s head to identify tissue to be removed, placing an ultrasound device into the treatment area, transmitting ultrasound energy at frequencies between 1 KHz and 20 MHz, and removing tissue outside the head.
-
24. A method for removing blood clots from a patient'"'"'s intracranial space using a therapeutic apparatus, the method comprising:
-
forming at least one aperture in the patient'"'"'s skull; advancing a therapeutic apparatus having a visualization feature and an ultrasound feature through the aperture to a target location within the intracranial space; identifying blood clots; transmitting ultrasound energy from the ultrasound device; and removing blood clots outside the patient'"'"'s head. - View Dependent Claims (25)
