Additional Contraindication: The Medtronic Models 3873 1 x 8 and the 3874 1 x 8 Compact Test Stimulation Leads are contraindicated for long-term implantation. The lead MUST BE REMOVED within ten (10) days of implant. ## Device Story Test stimulation lead kits consisting of thin, insulated wires with distal metal electrodes; intended for temporary connection to external neurostimulator (ENS) and screening cable. Device delivers electrical stimulation to block pain signals in target areas. Used in clinical settings by healthcare providers for short-term trial periods (max 10 days) to assess patient response to neurostimulation before permanent implant. Output is electrical current; clinical decision-making relies on patient feedback during trial to determine efficacy of pain management. Benefits include identifying suitable candidates for permanent spinal cord stimulation systems. ## Clinical Evidence Bench testing only. No clinical data provided. In vitro testing confirmed device met all design and performance requirements. Biocompatibility testing performed in compliance with ISO 10993-1. ## Technological Characteristics Thin wire lead with insulative coating and distal metal electrodes. Designed for temporary use (max 10 days). Sterilized via 100% Ethylene Oxide (EtO). Materials assessed for biocompatibility per ISO 10993. No software or active electronic components within the lead itself; functions as a passive conduit for electrical stimulation from an external neurostimulator. ## 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 3862 Verify Temporary Screening Lead ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

1 x 8 Compact Test Stimulation Leads | |-----------------|-----------------------------------------------------------------------------------| | Common Name: | Trialing Leads | | Classification: | Class II | | Product Code: | GZB | #### Predicate Devices The predicate device for the Medtronic Model 3873 1 x 8 Test Stimulation Leads and the Model 3874 1 x 8 Compact Test Stimulation Leads is the currently available Model 3862 Verify Temporary Screening Lead. #### Device Description The Model 3873 1 x 8 and the Model 3874 1 x 8 Compact are test stimulation lead kits. A test stimulation lead is a thin wire covered by an insulative coating, which is intended to be connected to a screening cable and an external neurostimulator (ENS). The lead has small metal electrodes near its tip through which the ENS delivers electrical stimulation to an area where pain signals will be blocked. #### Intended Use The Model 3873 1 x 8 and Model 3874 1 x 8 Compact Test Stimulation Leads are indicated as an aid is indicated as an aid in the management of chronic, intractable, unilateral or bilateral pain associated with the following: - Failed Back Syndrome or Low Back Syndrome or Failed Back; ● Image /page/0/Picture/16 description: The image shows the Medtronic logo.

Below the word "Medtronic" is the word "Confidential". {1}------------------------------------------------ - Radicular Pain Syndrome or Radiculopathies resulting in pain secondary to . Failed Back Syndrome; - Post Laminectomy Pain; ● - Unsuccessful Disk Surgery; ◆ - Degenerative Disk Disease (DDD/ Herniated pain refractory to conservative . and surgical interventions; - Peripheral Causalgia; . - Epidural Fibrosis; . - Arachnoiditis or Lumbar Adhesive Arachnoiditis; . - Complex Regional Pain Syndrome (CRPS) or Reflex Sympathetic Dystrophy . (RSD) or Causalgia; and, - Multiple Back Surgeries . Additional Contraindication: The Medtronic Models 3873 1 x 8 and the 3874 1 x 8 Compact Test Stimulation Leads are contraindicated for long-term implantation. The lead MUST BE REMOVED within ten (10) days of implant. #### Summary of Studies In Vitro testing was performed to support substantial equivalence to the predicate device. The Model 3873 1 x 8 and the Model 3874 1 x 8 Compact Test Stimulation Lead Kits met all specified design and performance requirements. #### Sterilization The Medtronic Model 3873 1 x 8 and the Model 3874 1 x 8 Compact Test Stimulation Lead Kits are labeled STERILE. The Model 3873 1 x 8 and the Model 3874 1 x 8 Compact Test Stimulation Lead Kits will be sterilized using the same 100% Ethylene Oxide (EtO) sterilization process as the predicate device. #### Biocompatibility All device materials / components were assessed for biocompatibility consistent with ISO- 10993, "Biological Evaluation of Medical Devices Part 1: Evaluation and Testing". All materials were found to be biocompatible and in compliance to ISO 10993-1. #### Conclusion Through data and information presented, as well as similarity to legally marketed devices, Medtronic, Inc. considers the Model 3873 1 x 8 and the Model 3874 1 x 8 Compact Test Stimulation Lead Kits to be substantially equivalent to legally marketed predicate devices.
