Abstract

A coupling pad can be used with a transducer element. Ultrasound produced by the transducer element can be propagated through the coupling pad to a patient. In one arrangement, the pad is a pouch containing a pliant substance. In other arrangements, the pad is a somewhat solid member formed of a material that transmits ultrasound waves efficiently. The pad may be configured to fit between a patient'"'"'s skin and a transducer element so that output from the transducer element passes through the pad to a treatment site of the patient.

Claims

1. A pad for use with a therapeutic ultrasonic treatment device configured to apply ultrasonic energy to a patient'"'"'s head, comprising:

a pouch defining a chamber; and

an ultrasonic coupling media disposed within the chamber of the pouch;

wherein the pad is configured to fit between a patient'"'"'s skin and a transducer element of the treatment device.

2. The pad of claim 1, wherein the pad is pliant and conforms to the topology of the patient'"'"'s skin.

3. The pad of claim 1, wherein the ultrasonic coupling media comprises gel.

4. The pad of claim 1, wherein the pad is configured to provide a gap between the transducer element and the patient'"'"'s skin.

5. The pad of claim 1, the treatment device comprises a headset configured for ultrasound treatment of a patient'"'"'s head.

6. The pad of claim 5, wherein the headset comprises a pair of transducers.

7. The pad of claim 1, wherein the pad is a disposable pad suitable for at least one ultrasound treatment.

8. A system for outputting an ultrasound field to a person'"'"'s head, comprising:

a transducer element configured to produce an ultrasound field into a treatment site in a person'"'"'s head; and

a pad including a covering containing an ultrasonic coupling agent, the pad being sized and configured to separate the transducer element and the skin of the patient'"'"'s head.

9. The system of claim 8, further comprising a second transducer element and a second pad, the second pad including a covering containing a coupling agent, the second pad being sized and configured to separate the second transducer element and the skin of the patient'"'"'s head.

10. The system of claim 9, further comprising a headset configured to hold the first and second transducer elements about the person'"'"'s head such that the first and second pads are compressed between the corresponding transducer elements and the patient.

11. The system of claim 8, wherein the coupling agent comprises an ultrasound gel.

12. A method of delivering ultrasound to a patient'"'"'s head, the method comprising:

positioning an ultrasound transducer element relative to a treatment site of a patient;

positioning a pliant pad between the transducer element and the patient, the pliant pad acoustically coupling the transducer to the patient;

delivering an clot removing agent to the treatment site; and

delivering ultrasound from the transducer element through the pad to the treatment site.

13. The method of claim 12, further comprising:

positioning a plurality of ultrasound transducer elements relative to the treatment site of a patient; and

positioning a corresponding pliant pad between each of the transducer elements and the patient.

14. The method of claim 12, further comprising compressing the pliant pad between the transducer element and the patient'"'"'s skin.

15. The method of claim 12, wherein the pad comprises a bag containing gel.
