Abstract
A transducer assembly for providing ultrasound may include a shaft operatively connected to a motor. A housing may include a receptacle for receipt of at least a portion of the shaft therein, two spaced-apart therapy elements, and an imaging element positioned between the therapy elements. The imaging element and the therapy elements may be spatially oriented in a confocal beam configuration. The assembly may be sized and shaped to pass through a trocar port.
Claims15
A transducer assembly for providing ultrasound, the assembly comprising:
- a shaft operatively connected to a motor;
- and
- a housing including a receptacle for receipt of at least a portion of the shaft therein, two spaced-apart therapy elements, and an imaging element positioned between the therapy elements, the imaging element and the therapy elements being spatially oriented in a confocal beam configuration and being configured to emit ultrasound energy to a targeted area,
- wherein the assembly is sized and shaped to pass through a trocar port.
A method for treating a targeted area of tissue, the method comprising:
- providing a transducer assembly sufficiently small to pass through a trocar port, the assembly including two spaced-apart therapy elements and an imaging element positioned between the therapy elements, the imaging element and the therapy elements being spatially oriented in a confocal beam configuration;
- and
- delivering 30 W of acoustic power to a targeted area of tissue via the transducer assembly.
The method according to claim 11, further comprising:
- calculating power density capacity (Pi) as follows:
- Pi=E2ωkt2Qm∈T33,
- wherein “E” is the electric field in rms voltage per unit thickness, “ω” is the radian frequency, 2πf, “kt” is the thickness coupling factor, “Qm” is the thickness mechanical quality factor, and “∈” is the dielectric constant.
A system for providing ultrasound comprising:
- a trocar including a port;
- a housing sufficiently small to pass through the port of the trocar;
- a shaft having a first end operatively connected to a motor and an opposing second end operatively connected to the housing;
- two spaced-apart therapy elements comprising multiple crystals from a surface of a spherical disk;
- and
- an imaging element positioned between the two therapy elements,
- wherein the imaging element and the therapy elements being spatially oriented in a confocal beam configuration,
