Abstract
An apparatus having an implantable ultrasound generating treating device to induce brain disorder treatment, suitable for implantation in or under the skull bone of a patient, includes several ultrasound generating transducers, which are connectable by a common electrical connection circuit to a generator, and wherein the ultrasound generating transducers each have one or several operating frequencies. The transducers include the group of transducers having several transducers driven by a same electrical drive signal, and connected to the generator system by a common electrical connection circuit, where the electric drive signal serves both as power signal and as a control signal for operating selectively, within said group, at least one or the other of a first transducer or sub-group of transducers, and of a second transducer or sub-group of transducers. The apparatus is also used to treat brain disorders.
Core Innovation
The invention relates to an implantable ultrasound generating treating device for the treatment of brain disorders by emission of ultrasound waves. The device is implanted in or under a skull bone and includes an ultrasound emitting grid with several ultrasound generating transducers held by a common holder.
The transducers extend along a surface of extension and are arranged as at least one group of several transducers connected to a generator. Within each transducer group, the ultrasound generating transducers each have one or several operating frequencies and are connectable by a common electrical connection circuit to the generator delivering electric drive signals.
The electric drive signal serves both as a power signal and as a control signal for operating selectively at least one or the other of a first transducer or sub-group and a second transducer or sub-group within the group. An implanted switch is connected upstream to the common electrical connection circuit and downstream separately to several distinct sub-groups, and the switch is mounted on the holder.
The generator and implanted switch arrangement includes clock-signal-based switching from the electric drive signal. The implantable switch comprises a clock signal generator to generate a clock signal from the electric drive signal, and the disclosure describes that switching may be clocked to activate distinct sub-groups. An electrical connection network includes a connection receiver with a rigid casing having a plug, where the casing is distinct from the common holder and has an upper flange of larger diameter than a lower portion of the casing.
Claims Coverage
The disclosed independent claim covers an implantable ultrasound apparatus for treatment of brain disorders, featuring a grouped ultrasound emitting grid controlled by an implanted switch. The claim includes five inventive features related to common electrical connection, power/control dual-use of an electric drive signal, selective operation of transducer sub-groups, clock signal generation, and a specific connection receiver/casing geometry.
Implantable ultrasound emitting grid for brain disorder treatment
An implantable ultrasound generating treating device implanted in or under a skull bone, comprising an ultrasound emitting grid with several ultrasound generating transducers held by a common holder extending along a surface of extension for inducing brain disorder treatment by emission of ultrasound waves.
Grouped transducer common electrical connection circuit
At least one group of several ultrasound generating transducers connectable by a common electrical connection circuit to a generator delivering electric drive signals driving ultrasound generation from the transducers, wherein the transducers each have one or several operating frequencies.
Electric drive signal as both power and control for selective transducer/sub-group operation
An implanted switch connected upstream to the common electrical connection circuit and downstream separately to several distinct sub-groups of one or several ultrasound generating transducers, where the group consists of several transducers commonly driven by a same electrical drive signal and the electric drive signal serves both as a power signal and as a control signal for operating selectively a first transducer or sub-group versus a second transducer or sub-group.
Clock signal generator generating clock signal from electric drive signal
An implanted switch mounted on the holder that comprises a clock signal generator to generate a clock signal from the electric drive signal.
Connection receiver with rigid casing and flange geometry distinct from common holder
An electrical connection network comprising a connection receiver having a rigid casing with a plug located within the casing, where the casing is distinct from the common holder and has an upper flange of larger diameter than a lower portion of the casing.
Overall, the claim set centers on an implantable ultrasound emitting grid whose transducer sub-groups are selectively activated via an implanted switch controlled using an electric drive signal that functions as both power and control, with clock-signal generation derived from the electric drive signal, and with defined electrical connection receiver hardware geometry.
