Systems for treating an obese patient include one or more sensors configured to sense one or more physical parameters of the patient and one or more implanted stimulators configured to apply a stimulus to the stomach in response to the sensed parameters. Methods of treating an obese patient include sensing one or more physical parameters of the patient and applying a stimulus to the stomach with one or more implanted stimulators in response to the sensed parameters.

Methods for selecting stimulation parameter sets guide a clinician towards an effective set(s) of stimulation parameters. The clinician first evaluates the effectiveness of a small number of trial stimulation parameters sets from a Measurement Table comprising for example, four stimulation parameter sets, measuring the perception threshold and maximum threshold levels. The maximum comfortable step size and desired field shift resolution are determined, and are used along with the measured threshold levels to determine an appropriate step size to use in the current steering process. In order to maintain paresthesia at a relatively constant level during the steering process, a Superposition Equalization (SEQ) algorithm is used to compensate for the physical characteristics of the lead array, i.e., electrode separation and size. A multiplier is determined and a modifying function is used to apply this multiplier to the electrode energy output during transition to maintain a relatively constant current density.

An adjustable writing board includes a planar member having a front face, a rear face opposed to the front face, two side edges slidably engaged with a first station and a second station respectively; a selective third station slidably engaged with a middle portion of the planar member; a selective remote control panel electrically connected with the first station, the second station, and/or the third station to control operations thereof; wherein each of the first station, the second station, and/or the third station comprises a locking mechanism having a slide guiding rail, a wheel roller slidably received in the slide guiding rail, and a plurality of stoppers, which can retract and contract to block and release the wheel roller.

A spinal cord stimulation (SCS) system includes multiple electrodes, multiple, independently programmable, stimulation channels within an implantable pulse generator (IPG) which channels can provide concurrent, but unique stimulation fields, permitting virtual electrodes to be realized. The SCS system includes a replenishable power source (e.g., rechargeable battery), that may be recharged using transcutaneous power transmissions between antenna coil pairs. An external charger unit, having its own rechargeable battery can be used to charge the IPG replenishable power source. A real-time clock can provide an auto-run schedule for daily stimulation. An included bi-directional telemetry link in the system informs the patient or clinician the status of the system, including the state of charge of the IPG battery. Other processing circuitry in the IPG allows electrode impedance measurements to be made. Further circuitry in the external battery charger can provide alignment detection for the coil pairs.

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. Further, the DBS system allows up to two electrode arrays (30, 30′) to be attached to the implantable pulse generator (20), thereby eliminating the requirement for implanting two independent implantable pulse generators for bilateral stimulation of deep brain structures.

摘要:
An operating room connector is used in conjunction with a multiple electrode SCS system which can easily detach and connect to an external trial stimulator (ETS). By connecting the electrode SCS system to a stylet handle, and then locking the stylet handle within a slot of the connector platform, a user is able to minimize the required steps in connecting the ETS to the implanted SCS lead system. The ETS can then be used to readjust the position of the electrode array(s) previously implanted to deliver an optimal stimulation therapy.
摘要:
The invention is a system and method for detecting the status of a rechargeable battery included within an implantable medical device. The medical device can incorporate a status indicator which signals the user concerning the battery status, e.g., low battery level. The signal may be audible or it may arise from an electrical stimulation that is perceptually distinguished from the operative, therapeutic stimulation. The external programmer may also incorporate a second battery status indicator that is visual, audible, or physically felt. Battery status data may be conveyed on visual displays on the external programmer by uploading this information from the medical device using a bidirectional telemetry link. Such battery status data are helpful to the user to indicate when the battery should be recharged and to the clinician to monitor patient compliance and to determine end-of-useful life of the rechargeable battery.
