• Device Name: LAMITRODE LEADS
• Applicant: Advanced Neuromodulation Systems
• Product Code: GZB · Neurology
• Decision Date: Jun 3, 1999
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 882.5880
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

Advanced Neuromodulation Systems, Inc.'s Lamitrode Leads are intended to be used with Advanced Neuromodulation Systems extensions and/or receivers, transmitters, and antennae to electrically stimulate spinal cord fiber tracts for treatment of chronic pain of the extremities and/or trunk. The proposed device modification does not affect the original intended use of the legally marketed device.

Device Story

Lamitrode leads are implantable spinal cord stimulator leads consisting of spaced electrodes connected by wires within a cover sheath. Leads are introduced into the epidural space via hemilaminectomy, positioned superior to the spinal segment responsible for pain impulse transmission. The device connects to an external or implanted radio-frequency (RF) receiver or pulse generator to deliver electrical stimulation to spinal cord fiber tracts. Used by physicians to treat chronic pain of the trunk and limbs. The device serves as a conduit for electrical signals; it does not process data or contain software. Benefits include pain management through electrical neuromodulation.

Clinical Evidence

Bench testing only. Biostability testing of polyurethane and silicone materials provided in manufacturer's Master File. Comparative bond strength testing demonstrated that the polyurethane lead insulator to platinum-cured paddle bond is superior to the current product.

Technological Characteristics

Implantable multi-electrode catheter; Platinum/Iridium electrodes; Stainless Steel 304 contact terminals; Polyurethane lead insulator; Braided wire cable; 4, 8, or 16 electrode configurations; 58-80 cm length; Sterile, prescription-only; No software or electronic processing components.

Indications for Use

Indicated for treatment of chronic pain of the trunk and limbs, either as sole mitigating agent or as adjunct to other therapies in multidisciplinary approach. Intended for use with ANS extensions, receivers, transmitters, and antennae.

Regulatory Classification

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

• ANS spinal cord stimulator systems (K853643, K905255, K960728)
• Medtronic spinal cord stimulator systems (K884948, K811655, K905407)

## Non-clinical Testing:

Biostability testing of the polyuethane and silicone material is provided in the manufacturer's Master File. Master File biocompatibility information demonstrates that the change to polyurethane and platinum cured silicone raises no significant safety or effectiveness questions relating to biocompatibility.

Comparative testing of product bond strength indicates that the polyurethane lead insulator to the platinum cured paddle has a better bond strength than the current product.
