摘要:
Biomaterials, such as hydrogels, can be mechanically secured to electrodes of an implantable device, such as electrodes made of noble metals. The hydrogel can be mechanically secured via anchoring features of the electrode. Anchoring features can include apertures, voids, textures, or other patterns created in or on the electrode. The hydrogel can incorporate into the anchoring features to mechanically hold the hydrogel against the electrode. The anchoring features, by being located in or on the electrode, can further increase the surface area of the electrode that is exposed to the hydrogel, which can facilitate the conduction of electrical signals between the electrode and surrounding biological tissue. The substrate supporting the electrode can include additional anchoring features that further assist in mechanically securing the hydrogel.

An electrostimulation device includes a computer generating an electrostimulation generator control signal and outputting a music signal, a transcutaneous electrostimulation generator, an electronic signal conduit, and an electrode coupler. The generator receives the generator control signal and the music signal, generates a nerve electrostimulation signal dependent upon the generator control signal, and outputs the nerve electrostimulation signal at the stimulation output and the music signal at an audio output. The coupler fits in an ear canal, has a speaker connected to the audio output to output the music signal into the ear canal when worn, and has electrostimulation electrodes conductively connected to the stimulation output through the electronic signal conduit to receive the nerve electrostimulation signal and positioned to contact tissue within the canal to transcutaneously apply the nerve electrostimulation signal thereto. The coupler supplies the nerve electrostimulation signal while music outputs from the speaker.

One aspect of the present disclosure includes a delivery tool configured to deliver a neurostimulator into a pterygopalatine fossa of a subject. The neurostimulator can include a body connected to an integral stimulation lead having one or more stimulating electrodes. The delivery tool can comprise a handle, an elongated shaft extending from the handle, a hub portion, and a double barrel sheath. The hub portion can be located between the shaft and a spine member that extends axially away from the hub portion. The hub portion can be sized and dimensioned to releasably mate with the neurostimulator. The double barrel sheath can be connected to the spine member. A central lumen can extend through at least a portion of the shaft and the hub portion. The central lumen can be adapted to receive a lead ejector for selective deployment of the stimulation lead from the double barrel sheath.

The present invention is in the field of induction of lucid dreams by Transcranial Alternating Current Stimulation (TACS). Lucid dreaming refers to a well-documented and scientifically accepted phenomenon that may occur during natural sleep. Lucid dreaming is characterized by awareness of the fact that one is dreaming, an increased chance of control over the events that are occurring within the dream and increased logical or rational thought during the dream.

An implantable head-mounted unibody peripheral neurostimulation system is provided for implantation in the head for the purpose of treating chronic head pain, including migraine. The system may include an implantable pulse generator (IPG) from which multiple stimulating leads may extend sufficient to allow for adequate stimulation over multiple regions of the head, preferably including the frontal, parietal and occipital regions. A lead may include an extended body, along which may be disposed a plurality of surface metal electrodes, which may be sub-divided into a plurality of electrode arrays. A plurality of internal metal wires may run a portion of its length and connect the IPG's internal circuit to the surface metal electrodes. The IPG may include a rechargeable battery, an antenna, and an application specific integrated circuit. The IPG may be capable of functional connection with an external radiofrequency unit for purposes that may include recharging, diagnostic evaluation, and programming.

A device for controlling operation of a nerve-modulating implant unit from a location external to the body of the subject is provided. The device may include a flexible substrate configured for removable attachment to a subject's skin, a primary antenna disposed on the flexible substrate, and at least one processing device. The processing device may be configured to cause generation of a modulation control signal and application of the modulation control signal to the primary antenna in order to wirelessly transmit the modulation control signal to a secondary antenna on the implant unit to cause modulation of at least one nerve using energy transmitted wirelessly from the primary antenna to the secondary antenna, and cause a plurality of predetermined alterations of at least one characteristic of the modulation control signal over successive applications of the modulation control signal during a therapy period.

Embodiments described herein generally relate to devices and methods for stimulation or recording of accommodation of an eye. Accommodation of an eye naturally occurs through contraction of the ciliary muscle. Embodiments described herein can deliver electrostimulation to the ciliary muscle through a pair of electrodes which deliver power over an area of the sclera which is both positioned above and over an area which is substantially equivalent to the surface area of the ciliary muscle. In further embodiments, electrical impulses produced by the ciliary muscle can be received by one or more electrodes positioned proximate the ciliary muscle. Thus, by embodiments described herein, accommodation of the eye can be reproducibly achieved by external stimulation of the ciliary muscle or measured based on electrical impulses generated by or in conjunction with the ciliary muscle.

A sleep apnea treatment device may include a flexible carrier configured to be implanted in a body of a subject. The device may also include at least one electrode disposed on the flexible carrier, the at least one electrode being configured to modulate nerve fibers of the subject. A flexible antenna may be disposed on the flexible carrier, the flexible antenna electrically connected to the at least one electrode in a manner permitting at least some energy received by the flexible antenna to be transferred to the at least one electrode. The flexible antenna may include: at least a first conductive trace arranged on a first side of the flexible carrier, the at least a first conductive trace defining at least a first elongated space between portions thereof: and at least a second conductive trace arranged on a second side of the flexible carrier, the at least a second conductive trace defining at least a second elongated space between portions thereof, wherein the at least a first conductive trace is at least partially offset from the at least a second conductive trace such that portions of the first conductive trace overly the at least a second elongated space and wherein portions of the second conductive trace underlay the at least a first elongated space.
摘要:
An electrode that functions alone, in clusters or arrays can be used to measure and/or deliver voltages through skin covered with hair by achieving reliable skin contact. In one form, a composite metal electrode has several raised points capable of passing through hair to contact the skin directly between hairs. Electrode points are distributed evenly over a flat circular or curved base to create a composite electrode or cluster in which all electrode points electrically couple to one another and to an output device. In another form of the invention, each electrode point is connected by a separate conductor wire to a selector that evaluates the signal during use and determines which of the electrode points are to be coupled to an output device.
