Device for treating the sensory capacity of a person and method of treatment with the help of such a device
First Claim
1. A system for treating at least one sensory capacity of a person with a help of a stimulation device comprising an electronic converter for converting a sensory signal into an electronic signal for controlling at least one transducer for emitting signals that are images of the sensory signal, the system being characterized in that the stimulation device is a device for direct ultrasound stimulation of a sensory cortex of a patient'"'"'s brain, the ultrasound stimulation device comprising:
- at least one support that is adapted to be implanted in a patient'"'"'s skull and that includes at least one internal wall; and
at least one ultrasound transducer carried by the support (2) and adapted for emitting ultrasound waves (U) through the internal wall of the support towards a determined zone of the sensory cortex of the patient'"'"'s brain in order to generate modulation of a brain activity in the cortex, the ultrasound transducer being driven by the electronic converter to emit ultrasound signals that are images of the sensory signal;
wherein the ultrasound stimulation device is provided with a flap presenting an internal face through which ultrasound waves are emitted, wherein the flap is designed to be slid between hemispheres of the patient'"'"'s brain;
wherein the flap is concave and semi-rigid and the implanted support comprises an internal face through which ultrasound waves are emitted, and the flap has ultrasound waves also emitted therethrough.

Abstract
A system for treating at least one sensory capacity of a person with the help of a stimulation device comprises an electronic converter of a sensory signal into an electronic signal for controlling at least one transducer for emitting signals that are images of the sensory signal. The stimulation device for direct ultrasound stimulation of the sensory cortex of a brain comprises at least one support that is implantable in a skull and that includes at least one internal wall and at least one ultrasound transducer carried by the support. Means for emitting focused ultrasound waves through the internal wall of the support towards a determined zone of the sensory cortex of the patient'"'"'s brain in order to generate modulation of the brain activity in the cortex are provided. The ultrasound transducer is driven by the electronic converter to emit focused ultrasound signals that are images of the sensory signal.

12. A method of treatment comprising using ultrasound waves emitted in a cranium of a patient in order to stimulate a determined zone of a sensory cortex of a patient'"'"'s brain using a treatment system, wherein the method further comprises:
-
forming a craniectomy hole in the patient'"'"'s cranium in register with a zone of a primary visual cortex of the brain; opening dura mater; sliding a flap of an ultrasound stimulation device between the brain hemispheres; and emitting ultrasound waves through an internal face of the flap;
wherein the treatment system comprises;an electronic converter for converting a sensory signal into an electronic signal for controlling at least one transducer for emitting signals that are images of the sensory signal, the treatment system being characterized in that the ultrasound stimulation device is a device for direct ultrasound stimulation of the sensory cortex of the patient'"'"'s brain, the ultrasound stimulation device comprising; at least one support that is adapted to be implanted in the patient'"'"'s skull and that includes at least one internal wall; and at least one ultrasound transducer carried by the support and adapted for emitting ultrasound waves through the internal wall of the support towards the determined zone of the sensory cortex of the patient'"'"'s brain in order to generate modulation of a brain activity in the cortex, the ultrasound transducer being driven by the electronic converter to emit ultrasound signals that are images of the sensory signal;
wherein the ultrasound stimulation device is provided with the flap presenting an internal face through which ultrasound waves are emitted, wherein the flap is designed to be slid between hemispheres of the patient'"'"'s brain and is used after the support has been mounted in the patient'"'"'s skull in register with the zone for treatment of the sensory cortex of the brain;wherein the flap is concave and semi-rigid and the implanted support comprises an internal face through which ultrasound waves are emitted, and the flap has ultrasound waves also emitted therethrough. - View Dependent Claims (13, 14, 15)
