Abstract
A focused ultrasound system includes an ultrasound transducer device forming an opening, and having a plurality of transducer elements positioned at least partially around the opening. A focused ultrasound system includes a structure having a first end for allowing an object to be inserted and a second end for allowing the object to exit, and a plurality of transducer elements coupled to the structure, the transducer elements located relative to each other in a formation that at least partially define an opening, wherein the transducer elements are configured to emit acoustic energy that converges at a focal zone.
Claims35
A focused ultrasound system configured for treatment of a body part, comprising:
- an ultrasound transducer device having a ring configuration and forming an opening sized to allow a portion of the body to pass through and exit the opening, the ultrasound device having a plurality of transducer elements positioned at least partially around an inward facing surface of the ring configuration;
- and
- a controller for operating the transducer elements to focus ultrasound waves transmitted by the transducer elements,
- wherein the transducer elements are arranged at an angle in a slanted orientation to form a partial conical configuration so as to prevent the transmitted ultrasound waves from damaging any of the transducer elements during operation.
A method of treating body tissue with ultrasound energy, comprising:
- passing a portion of a body part through an ultrasound transducer device having a ring configuration forming an opening, the ultrasound transducer device having a plurality of transducer elements positioned at least partially around an inward facing surface of the ring configuration;
- and
- at least one of configuring or operating the transducer elements to transmit ultrasound waves focused at a location outside a volume surrounded by the ring configuration so as to prevent damage to any of the transducer elements during operation.
A focused ultrasound system configured for treatment of a body part, comprising:
- an ultrasound transducer device having a ring configuration and forming an opening sized to allow a portion of the body to pass through and exit the opening, the ultrasound device having a plurality of transducer elements positioned at least partially around an inward facing surface of the ring configuration;
- and
- a controller for operating the transducer elements to focus ultrasound waves transmitted by the transducer elements,
- wherein the transducer elements are positioned and spaced so as to not oppose one another in a fixed arrangement, such that the transmitted ultrasound waves are prevented from damaging any of the transducer elements.
