Abstract

An ultrasound medical system includes an ultrasound end effector and at least one non-ultrasound tissue-property-measuring sensor. The ultrasound end effector includes a medical ultrasound transducer assembly having at least one medical-treatment ultrasound transducer. The at-least-one non-ultrasound tissue-property-measuring sensor is supported by the ultrasound end effector and is positionable in contact with patient tissue.

Claims

1. An ultrasound medical system comprising:

an ultrasound end effector, wherein the ultrasound end effector includes a sheath having an exterior surface, and wherein the ultrasound end effector is an ultrasound interstitial end effector which is interstitially insertable into patient tissue;

at least one non-ultrasound tissue-property-measuring sensor, wherein the at-least-one non-ultrasound tissue-property-measuring sensor is attached to the ultrasound interstitial end effector and is fixedly disposed substantially flush with the exterior surface; and

a medical ultrasound transducer assembly having at least one medical-treatment ultrasound transducer, wherein the medical ultrasound transducer assembly including the medical-treatment ultrasound transducer is surrounded by the sheath;

wherein the at-least-one non-ultrasound tissue-property-measuring sensor is supported by the ultrasound interstitial end effector and is disposable in contact with patient tissue; and

wherein the exterior surface includes at least one balloon portion which is expandable and contractible and which is expandable against patient tissue to provide at least some stabilization of the ultrasound interstitial end effector with respect to patient tissue, wherein a first balloon portion surrounds the medical ultrasound transducer assembly and acts as an acoustic window and longitudinally overlaps the medical-treatment ultrasound transducer, and wherein an acoustic coupling medium is disposable between the medical ultrasound transducer assembly and the first balloon portion.

2. The ultrasound medical system of claim 1, wherein the ultrasound interstitial end effector includes a longitudinal axis, wherein the at-least-one non-ultrasound tissue-property-measuring sensor includes a first non-ultrasound tissue-property-measuring sensor and a second non-ultrasound tissue-property-measuring sensor, and wherein the at-least-one medical-treatment ultrasound transducer is disposed longitudinally between the first and second non-ultrasound tissue-property-measuring sensors.

3. The ultrasound medical system of claim 1, wherein the at-least-one non-ultrasound tissue-property-measuring sensor measures tissue temperature.

4. The ultrasound medical system of claim 1, wherein the at-least-one non-ultrasound tissue-property-measuring sensor measures tissue electric impedance.

5. The ultrasound medical system of claim 1, wherein the exterior surface includes a second balloon portion longitudinally spaced apart from the medical ultrasound transducer assembly.

6. The ultrasound medical system of claim 1, also including a handpiece operatively connected to the ultrasound interstitial end effector, wherein the ultrasound interstitial end effector has a longitudinal axis and a shaft, wherein the medical ultrasound transducer assembly is supported by the shaft, and wherein the shaft is rotatable with respect to the handpiece about the longitudinal axis.

7. An ultrasound medical system comprising:

an ultrasound interstitial end effector, wherein the ultrasound interstitial end effector includes a sheath having an exterior surface;

at least one non-ultrasound tissue-property-measuring sensor, wherein the at-least-one non-ultrasound tissue-property-measuring sensor is deployable to extend away from the exterior surface into patient tissue to provide at least some stabilization of the ultrasound interstitial end effector with respect to patient tissue and is retrievable to retract back toward the exterior surface; and

a medical ultrasound transducer assembly having at least one medical-treatment ultrasound transducer, wherein the medical ultrasound transducer assembly including the medical-treatment ultrasound transducer is surrounded by the sheath;

wherein the at-least-one non-ultrasound tissue-property-measuring sensor is supported by the ultrasound interstitial end effector and is disposable in contact with patient tissue; and

wherein the exterior surface includes at least one balloon portion which is expandable and contractible and which is expandable against patient tissue to provide at least some stabilization of the ultrasound interstitial end effector with respect to patient tissue, wherein a first balloon portion surrounds the medical ultrasound transducer assembly and acts as an acoustic window and longitudinally overlaps the medical-treatment ultrasound transducer, and wherein an acoustic coupling medium is disposable between the medical ultrasound transducer assembly and the first balloon portion.

8. The ultrasound medical system of claim 7, wherein the at-least-one non-ultrasound tissue-property-measuring sensor is storable inside the exterior surface.

9. The ultrasound medical system of claim 7, wherein the ultrasound interstitial end effector includes a longitudinal axis, wherein the at-least-one non-ultrasound tissue-property-measuring sensor includes a first non-ultrasound tissue-property-measuring sensor and a second non-ultrasound tissue-property-measuring sensor, and wherein the at-least-one medical-treatment ultrasound transducer is disposed longitudinally between the first and second non-ultrasound tissue-property-measuring sensors.

10. The ultrasound medical system of claim 7, wherein the at-least-one non-ultrasound tissue-property-measuring sensor measures tissue temperature.

11. The ultrasound medical system of claim 7, wherein the at-least-one non-ultrasound tissue-property-measuring sensor measures tissue electric impedance.

12. The ultrasound medical system of claim 7, wherein the exterior surface includes a second balloon portion longitudinally spaced apart from the medical ultrasound transducer assembly.

13. The ultrasound medical system of claim 7, also including a handpiece operatively connected to the ultrasound interstitial end effector, wherein the ultrasound end effector has a longitudinal axis and a shaft, wherein the medical ultrasound transducer assembly is supported by the shaft, and wherein the shaft is rotatable with respect to the handpiece about the longitudinal axis.
