Device Facts

• Record ID: K991784
• Device Name: RENEW LEAD EXTENSION
• Applicant: Advanced Neuromodulation Systems
• Product Code: GZB · Neurology
• Decision Date: Jun 24, 1999
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 882.5880
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

ANS Renew Lead Extensions are indicated for the treatment of chronic pain of the trunk and limbs, either as the sole mitigating agent, or as an adjunct to other modes of therapy used in a multidisciplinary approach. Lead extensions are intended to be used with Advanced Neuromodulation Systems, leads, receivers, transmitters, and antennae.

Device Story

Renew Lead Extensions are implantable accessories designed to increase the length of spinal cord stimulation leads. The device consists of a silicone connector body, Platinum/Iridium contacts, and a braided wire cable within a polyurethane sheath. It is used to connect a lead to a receiver or to externalize the connection for a trial stimulation period (up to 30 days). The device is implanted by a physician; it functions as a passive electrical conduit to facilitate signal transmission from the stimulator system to the spinal cord. By extending the reach of the lead, it allows for flexible placement of the receiver or external trial components, aiding in the management of chronic pain.

Clinical Evidence

Bench testing only. Verification testing included insulation resistance, conductor resistance, system impedance, dielectric strength, accelerated contact resistance, connector pull test, lead body flex life, strain relief flex life, stiffness, and setscrew block retention. All acceptance criteria were met.

Technological Characteristics

Materials: Platinum/Iridium contacts, polyurethane sheath, silicone connector body. Design: Braided wire cable, 10-30 cm length. Connectivity: Passive electrical extension for spinal cord stimulation leads. Sterilization: 100% ETO (SAL 1x10^-6).

Indications for Use

Indicated for patients with chronic pain of the trunk and limbs requiring spinal cord stimulation, either as a primary therapy or as an adjunct in a multidisciplinary approach.

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

• One Step Connect™ Leads (K960728)
• Octrode Neurostim Receiver (K930536)

#### Predicate Device:

Advanced Neuromodulation Systems, Inc., currently markets One Step Connect™ Leads under 510(k) # K960728 and Octrode Neurostim Receiver under 510(k) # K930536.

#### Device Description:

The Renew Lead Extension consists of a silicone connector body, with Platinum/Iridium contacts, and braided wire cable inside a polyurethane sheath. Lead extensions are designed to be implanted to add additional length to the lead for connection to a receiver or externalized for use during a trial stimulation period not to exceed 30 days.

#### Intended Use:

ANS Renew Lead Extensions are indicated for the treatment of chronic pain of the trunk and limbs, either as the sole mitigating agent, or as an adjunct to other modes of therapy used in a multidisciplinary approach. Lead extensions are intended to be used with Advanced Neuromodulation Systems, leads, receivers, transmitters, and antennae.

#### Comparison To Predicate Device:
