Abstract:
A methodology and system for lysing adipose tissue including directing ultrasonic energy (10) at a multiplicity of target volumes (12) within the region, which target volumes (12) contain adipose tissue, thereby to selectively lyse the adipose tissue in the target volumes (12) and generally not lyse non-adipose tissue in the target volumes (12) and computerized tracking (44) of the multiplicity of target volumes (12) notwithstanding movement of the body.
Abstract:
An ultrasonic medical device comprising an ultrasonic probe (25) and a collet assembly for probe attachment and detachment, and a method of removing occlusions in blood vessels using the ultrasonic medical device. The probe (25) detachability allows insertion, manipulation and withdrawal independently of a device body. The collet assembly (5) comprises a compression clamp (10) capable of releasably receiving the probe (25), and a compression housing (14) that initiates a minimal area "line-contact" between the collet assembly segments upon engagement. A line-contact lip (21) ensures consistent and repeatable contact between the compression clamp (10) and the compression housing (14) at a pre-determined location to provide a consistent closing force on the probe (25) for any selected tightening torque. The line- contact between the collet assembly segments provides efficient ultrasonic energy transfer from an ultrasonic energy source (30) to the probe (25) thereby increasing probe efficiency during tissue ablation.
Abstract:
A transverse mode ultrasonic probe (6) is provided which creates a cavitation area along its longitudinal length, increasing the working surface of the probe. Accessory sheaths (104, 107, 108, 111, 121) are also provided for use with the probe to enable a user to select from features most suited to an individual medical procedure. The sheaths provide acoustic enhancing and aspiration enhancing properties, and/or can be used as surgical tools or as medical access devices, protecting tissue from physical contact with the probe.
Abstract:
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.
Abstract:
A method for destructing, reducing or removing mammalian tissue with an ultrasonic device is disclosed, comprising contacting the tissue with a transverse mode ultrasonic probe, and transmitting ultrasonic energy to the probe, until the tissue is fragmented by emulsification. The probe can be used with acoustic and/or aspirations sheaths to enhance destruction and removal of an occlusion and in combination with an imaging device to effect remodeling of human tissue in medical and cosmetic surgical procedures.
Abstract:
A device is described that can be used by surgeons to provide quick and accurate face-lifting maneuvers that minimize the amount of tissue that has to be removed. The device is comprised of a shaft with a relatively planar but possibly lenticulate and even slightly curved tip that can divide and energize various tissue planes causing contraction especially via the fibrous tissues. Various forms of energy can be delivered down the shaft to heat and cause desirable tissue contraction. The device can also include a temperature sensor that can be used to control power output.
Abstract:
A hand-held ultrasonic surgical apparatus (10) with a focusing lens (18) for fragmenting or emulsifying a predetermined volume of a medium located generally near a focal length (26) from a concave surface (19) of the focusing lens (18) without significant heating of the medium, includes a housing (11) to be held, manipulated by a surgeon or physician, and an acoustic assembly (20) mounted within the housing (11). The acoustic assembly (20) has a resonant vibratory frequency that is primarily determined by the length of the acoustic assembly, and an axis (15) along which the ultrasonic vibratory energy is directed. The preferred range for the resonant vibratory frequency to achieve sufficient focusing, and sufficient ultrasonic power to fragment or emulsify tissue is between 100 kHz and 250 kHz. The acoustic assembly (20) includes an ultrasonic motor (12), a rear driver (16), a front driver (17), a compression fastener (28), and a focusing lens (18).

Abstract:
An apparatus for treating adipose tissue located beneath a patient's skin includes a main body portion that houses an ultrasound transducer that outputs transverse ultrasound waves to be applied to a patient's skin. The apparatus also includes a semisphere portion provided at a distal end of the apparatus and that is configured to contact the patient's skin when the patient is being treated with the apparatus. The apparatus further includes an intermediate portion provided between the main body portion and the semisphere portion, in which a connector that provides the ultrasound waves from the ultrasound transducer to the semisphere portion is housed. The intermediate portion is disposed substantially perpendicular to the main body portion.
