Abstract: An implantable pulse generator includes a current steering capability that allows a clinician or patient to quickly determine a desired electrode stimulation pattern, including which electrodes of a group of electrodes within an electrode array should receive a stimulation current, including the amplitude, width and pulse repetition rate of such current. Movement of the selected group of electrodes is facilitated through the use of remotely generated directional signals, generated by a pointing device, such as a joystick. As movement of the selected group of electrodes occurs, current redistribution amongst the various electrode contacts takes place. The redistribution of stimulus amplitudes utilizes re-normalization of amplitudes so that the perceptual level remains fairly constant. This prevents the resulting paresthesia from falling below the perceptual threshold or above the comfort threshold.

Abstract: A communication device (CD) exchanges messages with an implantable infusion pump via telemetry such that commands are supplied thereto and operational information is obtained therefrom. The CD is controlled, at least in part, by a processor IC according to a software program operating therein and provides feedback to a user via a visual display, an audio alarm, and a vibrational alarm, and allows input from the user via a touch sensitive keypad. Certain input functions are restricted by password. The visual display includes an icon and fixed element display region and a bitmap display region. The fixed element display region includes time and date displays, battery and drug level displays that decrement, and a moving delivery state display. Various screens allow operational or log information to be displayed and/or user entry of commands. Program features when disabled are removed from a series of screen options that can be scrolled through.

Abstract: A deep brain stimulation (DBS) system (10) provides a multiplicity of stimulation channels through which electrical stimuli may be delivered deep within the brain of a patient. The DBS system is powered by a rechargeable battery (27) . In one embodiment, the system has four channels driving sixteen electrodes (32). The DBS system is easily programmed for use by a clinician using a clinician programming system (60), and further affords a simple but highly advanced hand held programmer (50) control interface through which the patient may easily change stimulation parameters within acceptable limits. The DBS system (10) includes a small, implantable pulse generator (20) that is small enough to be implanted directly in the cranium of the patient, thereby eliminating the long lead wires and tunneling procedures that have been used in the past. The implantable pulse generator provides electrical stimuli in an open-loop fashion as defined by the stimulation parameters.

Abstract: An implantable connector, implantable lead assemblies, and implantable lead assembly kits are provided. The connector comprises an electrically insulative receptacle having a port configured for receiving an electrical lead body portion that carries an electrical terminal, and an electrical spring clip contact mounted within the receptacle. The electrical contact includes a collar and opposing lever arms. The collar is configured for being placed between an expanded state for receiving the terminal therein when the lead body portion is received within the port, and a collapsed state to firmly engage the terminal. The opposing lever arms are configured for being displaced using a tool to correspondingly place the collar between the expanded state and the collapsed state. The implantable connector can be incorporated into a lead and used to receive another lead to form the lead assembly. A tool can be provided with the connector to provide the lead assembly kit.
