Systems and methods of controlling a device using detected changes in a neural-related signal of a subject are disclosed. In one embodiment, a method of controlling a device or software application comprises detecting a first change in a neural-related signal of a subject, detecting a second change in the neural-related signal, and transmitting an input command to the device upon or following the detection of the second change in the neural-related signal. The neural-related signal can be detected using a neural interface implanted within a brain of the subject.

Systems and methods for providing neural stimulation and recording on a subject using flexible complementary CMOS probes are provided. Disclosed systems can include a flexible probe adapted for insertion into a portion of a brain of the subject, the flexible probe comprising a tail portion and a head portion. The tail portion can include a plurality of electrodes configured to be coupled to the brain and a plurality of front-end amplifiers. Each of the plurality of front-end amplifiers can be configured to amplify a signal received from a corresponding electrode of the plurality of electrodes. The head portion can include one or more inductors configured to enable two-way communication with a wireless reader through a near-field inductive link.

A transition microelectrode (108) can include a micro well array (104) having a plurality of microwells. The transition microelectrode (108) can further include a plurality of neuronal soma oriented within the plurality of microwells. A bioerodible probe guide (106) can be oriented over the microwell array (104). An electrode (103) can be electrically connected with the plurality of microwells. A transition microelectrode array (116) can include an electrode array having a plurality of the transition microelectrodes (108).

In one embodiment a medical tracking system, including a catheter to be inserted into blood vessels of a body-part of a living subject, and including a flexible shaft having a deflectable distal end, and a location tracking transducer in the distal end configured to output a signal indicative of a location of the transducer, a tracking subsystem to track locations of the distal end over time responsively to the signal, a display, and processing circuitry to add the tracked locations of the distal end to a movement log, and render to the display an image of at least part of the body-part with a representation of a length of the shaft of the catheter in at least one blood vessel of the body-part, with respective positions along the length of the shaft being located in the image responsively to respective ones of the tracked locations from the movement log.

In one example, the disclosure describes a method comprising receiving, by processing circuitry, information indicative of one or more evoked compound action potential (ECAP) signals. The one or more ECAP signals are sensed by at least one electrode carried by a medical lead. The processing circuitry determining that at least one characteristic value of the one or more ECAP signals is outside of an expected range. Responsive to determining that the at least one characteristic value of the one or more ECAP signals is outside of the expected range, the processing circuitry performs a lead integrity test for the medical lead.

In some examples, a processor of a system evaluates a therapy program based on a score determined based on a volume of tissue expected to be activated (“VTA”) by therapy delivery according to the therapy program. The score may be determined using an efficacy map comprising a plurality of voxels that are each assigned a value. In some examples, the efficacy map is selected from a plurality of stored efficacy maps based on a patient condition, one or more patient symptoms, or both the patient condition and one or more patient symptoms. In addition, in some examples, voxels of the efficacy map are assigned respective values that are associated with a clinical rating scale.

An implantable device and method of manufacture include a substantially hermetic polychlorotrifluoroethylene (PCTFE) enclosure with closely-spaced wires extending through a slit in the enclosure. A method for manufacturing the implantable device includes cutting a slit in a piece of polymer and extending a plurality of insulated wires through the slit. Each of the insulated wires are parallel to a neighboring wire of the insulated wires. The piece of polymer is thermally bonded around each wire of the plurality of insulated wires such that the piece of polymer is sealed around insulation of each wire with a portion of each wire extending through the piece of polymer.
