Patent number: 6666833Abstract: Systems and methods for focussing an ultrasound energy beam transmitted from an array of transducer elements located outside the body through a non-uniform tissue medium, such as a skull, to a location (e.g., a tumor) located inside the body by monitoring a signal representing reflected portions of the beam at a desired focal point or zone through a portion of the medium that does not significantly distort the reflected signal. In one embodiment, a focussed ultrasound system includes a plurality of transmitting transducer elements configured to deliver respective energy waves from locations outside the skull to a focal zone within the skull, the energy waves collectively comprising an energy beam. The system further includes an ultrasound detector having a fixed position relative to the transmitting elements, the detector configured to receive a signal comprising a reflected portion of the beam along a line-of-sight axis through a portion of the skull.Type: GrantFiled: November 28, 2000Date of Patent: December 23, 2003Assignee: Insightec-TxSonics LtdInventors: Zvi Friedman, Dov Maor

Patent number: 6645162Abstract: Cells are destroyed within a subcutaneous tissue region using a transducer disposed externally adjacent to a patient's skin. The transducer emits acoustic energy that is focused at a linear focal zone within the tissue region, the acoustic energy having sufficient intensity to rupture cells within the focal zone while minimizing heating. The transducer may include one or more transducer elements having a partial cylindrical shape, a single planar transducer element coupled to an acoustic lens, or a plurality of linear transducer elements disposed adjacent one another in an arcuate or planar configuration. The transducer may include detectors for sensing cavitation occurring with the focal zone, which is correlated to the extent of cell destruction. A frame may be provided for controlling movement of the transducer along the patient's skin, e.g., in response to the extent of cell destruction caused by the transducer.Type: GrantFiled: June 11, 2001Date of Patent: November 11, 2003Assignee: Insightec - Txsonics Ltd.Inventors: Zvi Friedman, Dov Maor, Shuki Vitek

Patent number: 6613004Abstract: A system for performing a therapeutic procedure using focused ultrasound includes a transducer array including a plurality of transducer elements, drive circuitry coupled to the transducer elements, and a controller coupled to the drive circuitry. The controller controls the drive circuitry to alternatively provide sets of the transducer elements with respective drive signals. Each of the sets of transducer elements are alternatively driven with the respective drive signals for a predetermined duration during a sonication, while substantially continuously focusing ultrasonic energy produced by the transducer elements of each set at a desired focal zone. The controller also controls a phase component of the respective drive signals to provide a predetermined size, shape, and/or location of the focal zone, and thereby necrose a target tissue region at the focal zone.Type: GrantFiled: April 21, 2000Date of Patent: September 2, 2003Assignee: InSightec-TxSonics, Ltd.Inventors: Shuki Vitek, Dov Maor

Patent number: 6613005Abstract: A focused ultrasound system includes a transducer array including a plurality of sub-arrays, each sub-array defining an acoustic emission surface and including a plurality of transducer elements thereon. A mechanical controller is coupled to the sub-arrays that includes actuators for moving the sub-arrays to adjust an orientation of the acoustic emission surfaces of respective sub-arrays to facilitate steering of acoustic energy emitted by the transducer elements towards a target tissue region. Drive circuitry provides drive signals to the transducer elements, whereby the transducer elements emit acoustic energy from their respective acoustic emission surfaces to ablate the target region, such as a tumor within a patient's brain.Type: GrantFiled: November 28, 2000Date of Patent: September 2, 2003Assignee: InSightec-TxSonics, Ltd.Inventors: Zvi Friedman, Dov Maor
