Patient carries device during screening period to manage stimulation parameters for chronic intractable pain. Features larger LCD for parameter display; RF transformer replaces previous antenna/receiver coil; relocated user interface controls. Physician programs device; patient uses during trial to assess therapy efficacy for pain management. ## Clinical Evidence No clinical data provided; substantial equivalence based on functional and electrical similarity to predicate devices. ## Technological Characteristics Portable external screener; RF transformer-based signal transmission; LCD interface; pushbuttons/switches for parameter control. Functionally equivalent to combined Model 3627/3210 units. ## Regulatory Identification An implanted spinal cord stimulator for pain relief is a device that is used to stimulate electrically a patient's spinal cord to relieve severe intractable pain. The stimulator consists of an implanted receiver with electrodes that are placed on the patient's spinal cord and an external transmitter for transmitting the stimulating pulses across the patient's skin to the implanted receiver. ## Predicate Devices - Model 3627 Screener ([K955291](/device/K955291.md)) - Model 3210 Transmitter ([K955291](/device/K955291.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Box 1250 Minneapolis, MN 55440-9087 (612) 572-5000 1-800-328-0810 FAX: (612) 572-5078 MAY 17 1996 Medtronic November 15, 1995 RE: 510(k) Notification: Medtronic Model 3628 Screener In order to comply with the Safe Medical Devices Act of 1990, this page will provide safety and effectiveness information to interested persons. SUMMARY OF SAFETY AND EFFECTIVENESS The Medtronic Model 3628 Screener is indicated for use in trial screening for SCS and PNS for chronic intractable pain of the trunk or limbs, as is the Model 3627 Screener and the Model 3210 Transmitter. The Model 3628 Screener is a combination of the Model 3627 Screener and the Model 3210 Transmitter. Electrically and functionally, it is the same as the two current products combined. The new Screener allows the patient to carry one unit rather than two during the screening period. There are only minor differences between the Model 3628 Screener and the commercially available Model 3627/3210 units, which are as follows: 1. A larger liquid crystal display (LCD); used to display parameter information. 2. The antenna and receiver coil in the current products have been replaced with a RF transformer. 3. Several items (pushbuttons, switches, etc.) have been relocated for improved ease of use. Therefore, the Model 3628 Screener is substantially equivalent to current Model 3627/3210 units.
