Localization and therapy system for treatment of spatially oriented focal disease
First Claim
1. A visualization and treatment transducer assembly comprising:
- a transducer housing having a main section and a detachable enclosure;
movable visualization transducer means disposed within said enclosure;
movable treatment transducer means disposed within said enclosure;
first drive means providing rotary motion to said visualization transducer means in two degrees of freedom;
second drive means providing rotary motion to said treatment transducer means in two degrees of freedom;
said visualization transducer means and said treatment transducer means having generally coaxial focal axes; and
said first and second drive means being operable independently of each other.

Abstract
A transducer assembly for visualization and treatment of transcutaneous and intraoperative sites includes in combination a visualization transducer and a treatment transducer, each of which are movable with both linear and rotary degrees of freedom. Movement of each transducer is by various motor and geared drive arrangements wherein certain degrees of freedom for one transducer are separate and independent from the degrees of freedom for the other transducer. At least one degree of freedom for each transducer is common and the transducers are moved concurrently.
One arrangement of the transducer combination is for prostate treatment and includes a specific shape and configuration for anatomical considerations and a control unit which is operable external to the patient to control both transducers and a reflective scanner which are inserted into the patient as part of the ultrasound probe.
