For this purpose, in an advantageous embodiment of the invention, a securing element, which is adapted on the end side to connect to a corresponding connection element in the dental implant part, particularly preferably which can be screwed into a thread of the dental implant part by the end side, and to which a distribution element for a cleaning fluid as well as an electrical contact element can be attached, which distribution element can be connected to an external media reservoir via a media channel, and via which electrical contact element, a power source that is connectable to an external power source can be electrically connected to the dental implant part.

The present disclosure provides a computer-implemented method for enhancing vision for a vision impaired user. The method comprises, for a point in an input image, determining (210) a weight for the point based on visual importance of the point in the input image; comparing (220) the weight for the point to a threshold; and if the weight for the point meets the threshold, determining (230) a first output value for an imaging element of a vision enhancement apparatus so that a difference between the first output value and an intensity level of a portion of the input image neighbouring the point increases with the weight, wherein the difference is at least one Just-Noticeable-Difference of the vision enhancement apparatus, such that when the first output value is applied to the imaging element of the vision enhancement apparatus to create a first visual stimulus, the first visual stimulus is substantially perceivable by the vision impaired user.

Bacteria, cancer cells, fungus and other harmful cells located beneath the surface of a mammal body can be effectively destroyed by passing an electrical current through the area to be treated. Electrodes are positioned on either side of the area to be treated, for example, gums, fingers, arms, legs, feet and torso, and an electric current is caused to flow between the electrodes and through the area to be treated. The electric current will destroy the bacteria, cancer cells, fungus or other harmful cells.

Electrical stimulation of specific facial and lingual nerves creates a more sustained pulsatility activity compared to stimulation of other cranial nerves. Pulsatility of arteries has intrinsic time constraints related to the time for vasodilation/constriction and time to return to baseline (T.sub.BL) after electrical stimulation which may affect the pulsatility response. Control of temporal patterning and the stimulation waveform maximizes the physiological response to cerebral pulsatility and its resulting effects on cerebral spinal fluid penetration into the brain parenchyma for a multitude of therapeutic uses including clearing misfolded proteins and/or administered pharmacological agents, diluting endogenous neurochemical concentrations within the brain, and reducing non-synaptic coupling.

The invention relates to a flexible electrode (8) made of a metal base material (10) with a coating (18) made of polycrystalline doped electrically conductive diamond and an intermediate layer (20) between the base material (10) and the coating (18), wherein the base material (10) is in the form of a needle or wire, wherein at least one circumferential, circular or spiral groove (12) is formed in the base material (10) about a longitudinal axis (17) of the base material (10).

A system for providing non-invasive neuromodulation to a patient includes a mouthpiece and a controller. The mouthpiece includes an elongated housing, a printed circuit board, and control circuitry mounted within the elongated housing. The controller includes an elongated u-shaped element, an electronic receptacle, and a microcontroller. A method for providing non-invasive neurorehabilitation of a patient including connecting a mouthpiece to a controller, transmitting a numeric sequence to the mouthpiece, generating a first hash code, transmitting the first hash code to the controller, generating a second hash code, comparing the second hash code with the first hash code, enabling electrical communication between the mouthpiece and the controller only if the first hash code matches the second hash code, contacting the mouthpiece with the patient's intraoral cavity, and delivering neurostimulation to the patient's intraoral cavity.

A system for treating obstructive sleep apnea (OSA) is described. The system may include a locking device having a size and shape selected to couple to skin along a jaw of a patient. The locking device may be configured to receive at least one of a needle or an introducer for insertion into a tongue of the patient for lead placement of a lead for OSA treatment, and lock at least a portion of the at least one of the needle or introducer in place to reduce movement of the needle or introducer within the tongue.

A device for electrical stimulation of one or more components of the periodontal complex and surrounding tissue of a tooth, for uses such as reducing orthodontic pain and encouraging tooth movement, has electrodes of a rigid, electrically conductive material in a fixed spatial relationship configured for application to oral mucosa and attached gingiva adjacent to, and along a periodontal ligament of, a root structure of a single tooth. An electrical circuit is configured for electrical connection to the at least two electrodes. The electrical circuit has an output providing a subsensory electrical stimulus comprising a waveform in accordance with predetermined stimulation parameters. After the electrodes are applied to the oral mucosa and attached gingiva adjacent to, and along the periodontal ligament of, a root structure of the tooth, a switch, when activated, activates the electrical circuit to output the electrical stimulus through the at least two electrodes.

An oral appliance for the treatment of obstructive sleep apnea includes a mouthpiece configured for being received in an oral cavity of a user. The mouthpiece may include a pulse oximeter, a pressure sensor, an airflow sensor, an actigraphy sensor, a noise detector, and at least one stimulator for providing stimulation to a user's tongue in the event of decreased oxygen saturation levels, increased pressure applied to occlusal surfaces of the user's dentition, decreased actual airflow levels and/or increased noise levels. A microprocessor receives data from the oxygen sensor, pressure sensor, airflow sensor, actigraphy sensor and noise detector, and activates the at least one stimulator.

An oral care implement herein may be embodied as an oral device for placement in the oral cavity. The device may include an insert configured for placement in the oral cavity in contact with a wearer's teeth and an activating member configured for placement in the oral cavity and selectively attachable to the insert.
