A device for reducing foreign body response in a subject caused by an electrode implanted in a subject's tissue. A base is secured to the subject, having a base aperture in proximity to the target site. The base can receive and align a body thereon. A body contains a chamber extending between a chamber aperture, aligned with the base aperture, at one end and a chamber opening at an opposite end. The chamber contains an acoustic coupling medium, such as polyvinyl alcohol cryogel, transmits acoustic vibrations from a transducer without altering their frequency. The transducer is mounted to the device and is configured to transmit acoustic vibrations into the chamber and through said acoustic coupling medium to the subject tissue at the target site, creating an acoustic field in the target site sufficient to reduce foreign body response in the subject where the electrode contacts the target tissue.

In some embodiments, an electrical probing stimulation pattern is delivered to the brain of a subject. A response to the electrical probing is analyzed, and used to determine a type of predicted seizure. The type of predicted seizure may be used to determine a treatment electrical stimulation pattern that may be administered to prevent onset of the predicted seizure. In some embodiments, a predicted seizure metric is calculated, which, in some implementations, acts as an indicator of “distance” (e.g., probability distance) to the predicted seizure. Furthermore, a subject model may be trained to assist with determining the type of predicted seizure, and determining the treatment electrical stimulation pattern.

Electrode devices are provided having certain thin film components, including at least one thin film contact and a temperature sensor associated with the contact. The temperature sensor can be used to monitor the temperature during use of the electrode device, including during electrical stimulation or ablation. Further, the temperature sensor can be used to identify the most effective temperature for stimulation or ablation.

The invention comprises an elongated device adapted for insertion, including self-insertion, through the body, especially the skull. The device has at least one effector or sensor and is configured to permit implantation of multiple functional components through a single entry site into the skull by directing the components at different angles. The device may be used to provide electrical, magnetic, and other stimulation therapy to a patient's brain. The lengths of the effectors, sensors, and other components may completely traverse skull thickness (at a diagonal angle) to barely protrude through to the brain's cortex. The components may directly contact the brain's cortex, but from there their signals can be directed to targets deeper within the brain. Effector lengths are directly proportional to their battery size and ability to store charge. Therefore, longer angled electrode effectors not limited by skull thickness permit longer-lasting batteries which expand treatment options.

A method produces a device adapted to be implanted into the human body for purposes such as neural stimulation, sensing or the like. The method includes: providing a stretchable layer or membrane of an insulating material; forming on the layer or membrane at least one stretchable conductive path; depositing at least one small bolus of a soft and conductive paste or material onto pre-defined areas or portions of the at least one conductive path, and inserting a first end portion of a conductive element 71 into the at least one bolus of soft conductive paste or material. A second end portion of the conductive element opposite to the first end portion is not inserted into the at least one bolus.

Systems and methods for stimulating the sensory cortex of an individual by obtaining a neuronal stimulation signal adapted to provide a movement cue for the individual and transmitting the neuronal stimulation signal to an electric contact of a neuronal stimulation electrode that is already implanted into the brain of the individual for a purpose different from providing the movement cue. Proprioceptive information is communicated to the individual by obtaining information about the body posture of the individual and applying a neuronal stimulation signal to an afferent axon targeting a sensory neuron in the cortex of the individual. The neuronal stimulation signal is determined based on the obtained body posture information and corresponds to the proprioceptive information. A first neuronal stimulation signal providing the movement cue and a second neuronal stimulation signal providing the proprioceptive information may be applied together to the cortex of the individual.

An implantable device includes a flexible cable, a circuit chip, a fluid adhesion layer, and a vapor deposited layer. The flexible cable includes a lead-in part, a stimulation part and a connection part connected between the lead-in part and the stimulation part. The circuit chip is fixed to a surface of one side of the lead-in part, and is electrically connected to the lead-in part. The fluid adhesion layer is adhered to an outer side of the circuit chip and an outer side of the lead-in part. The vapor deposited layer (4) is directly deposited on an outer side of the fluid adhesion layer.

Various embodiments of a system and method for the treatment of brain cancer using a subdurally-implanted alternating electric field generation apparatus are disclosed herein.

A method for creating artificial vision with an implantable visual stimulation device. The method comprises receiving image data comprising, for each of multiple points of an image, a depth value, performing a local background enclosure calculation on the image data to determine salient object information, and generating a visual stimulus to visualise the salient object information using the implantable visual stimulation device. Performing the local background enclosure calculation is based on a subset of the multiple points of the input image, and the subset of the multiple points is defined based on the depth value of the multiple points.

Methods and apparatus for improving cognitive function within a human. The invention utilizes an implanted device, such as an implantable signal generator or an implantable pump, to affect tissue elements within a Papez circuit of the human brain as well as tissue upstream or downstream from the Papez circuit. The implanted device delivers treatment therapy to thereby improve cognitive function by the human. A sensor may be used to detect various symptoms of the cognitive disorder. A microprocessor algorithm may then analyze the output from the sensor to regulate delivery of the stimulation and/or drug therapy.
