1. A therapy head comprising:
- an enclosure having a window, said enclosure adapted to be manipulated by hand;
at least one directional energy applicator suspended within said enclosure; and
a positioner programmed to maneuver the energy applicator within said enclosure, the positioner, comprising;
a first motor connected to a first traveler rod, the first traveler rod mechanically engaged to a first actuator;
a second motor connected to a second traveler rod, the second traveler rod mechanically engaged to a second actuator wherein the actuators are arranged to form an intersection between said first and second actuator, the directional energy applicator being movably positioned at the intersection of said first and second actuator;
wherein the positioner maneuvers the energy applicator to emit radiant energy through the window in order to deliver a precise energy dosage to patient tissue adjacent the window, and wherein the positioner is adapted to maneuver the energy application along a first axis controlled by said first motor and along a second axis controlled by said second motor, the second axis being perpendicular to the first axis.

Abstract
A therapy head for use in HIFU procedures is described. The therapy head has an enclosure with a window, an energy applicator and a means of moving the energy applicator within the enclosure. The therapy head uses motors and actuators to move the energy applicator, usually an ultrasound transducer, inside the enclosure. A controller is provided either internally or externally that allows the therapy head to identify and distinguish locations where the therapy head should be to radiate energy into a patient. The controller uses the motors and actuators to move the energy applicator into the desired locations.

16. A method of delivering ultrasound energy to a body surface, said method comprising:
-
engaging a hand held enclosure against a body surface; positioning the enclosure manually over one location on the body surface; and controlling a first motor and a second motor connected to a first actuator and a second actuator, respectively, to control the movement of an energy applicator according to a predetermined program within the hand held enclosure while the enclosure remains stationary relative to the body surface, wherein controlling the first motor controls the movement of the energy applicator along a first axis and controlling the second actuator controls the movement of the energy applicator along a second axis perpendicular to the first axis. - View Dependent Claims (17)
