Intended Use

The Stryker Intradiscal RF Generator is intended for the coagulation and decompression of disc material to treat symptomatic patients with annular disruption of contained herniated discs. The Stryker Intradiscal RF Generator will be used with the previously cleared Stryker RF Intradiscal Adapter and catheters such as Smith & Nephew Spinecath™ & Acutherm™ catheters.

Device Story

Stryker Intradiscal RF Generator is a radiofrequency lesion generator used for coagulation and decompression of intervertebral disc material. Device operates by delivering RF energy through a compatible intradiscal catheter (e.g., Smith & Nephew SPINECATH or ACUTHERM) to treat contained herniated discs. Used in clinical settings by physicians; device serves as power source for catheters previously cleared for percutaneous lumbar discectomy. Output is controlled thermal energy; clinical benefit is decompression of disc material to alleviate symptoms of herniation. Device requires use of Stryker RF Intradiscal Adapter.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on technological characteristics and operating principles compared to the predicate device.

Technological Characteristics

Radiofrequency lesion generator; delivers energy for tissue coagulation/decompression. Operates via connection to compatible intradiscal catheters and specific RF adapter. Class II device (21 CFR 882.4400).

Indications for Use

Indicated for symptomatic patients with annular disruption of contained herniated discs requiring coagulation and decompression of disc material. Contraindicated for patients with pain originating from structures other than contained herniated discs, free fragments, severe bony/spinal stenosis, or severely degenerative/disrupted discs. Special consideration required for patients with pacemakers, steroids, lupus, gout, uncontrolled diabetes, Ehlers-Danlos syndrome, autoimmune disease, or compromised immune systems.

Regulatory Classification

Identification

A radiofrequency lesion generator is a device used to produce lesions in the nervous system or other tissue by the direct application of radiofrequency currents to selected sites.

Use of the SPINECATH™ Intradiscal Catheter is not appropriate for treating patients who present pain that is suspected to originate from structures other than contained herniated discs, or when free fragments or severe bony stenosis are present. In addition, patients presenting severely degenerative or disrupted discs should be excluded.

Use of the Decompression Catheter is not appropriate for treating patients who present pain that is suspected to originate from origins other than herniated discs, or when free fragments or severe spinal stenosis are present. In addition, patients presenting with severely degenerative or disrupted discs should be excluded.

Use of the Smith & Nephew SPINECATH™ Intradiscal Catheter and ACUTHERM TM Decompression Catheter is appropriate for treating patients with herniations of intervertebral discs who would typically undergo automated or laser percutaneous lumbar discectomy.

Use of the Smith & Nephew SPINECATH™ Intradiscal Catheter and ACUTHERM ™ Decompression Catheter is appropriate for treating patients with herniations of intervertebral discs who would typically undergo automated or laser percutaneous lumbar discectomy.

Precautions: Patients taking steroids and patients with pacemakers, lupus, gout, uncontrolled diabetes, Ehlers-Danlos syndrome, prior open capsular procedures, autoimmune disease, or etiologies where their immune systems are compromised require special consideration.

## Substantial Equivalence

The Stryker Intradiscal RF Generator has the same intended (SE) Rational: use as the Smith & Nephew ElectroThermal 20S Spine Generator (K033981). This device and the predicate device have the same technological characteristics, the same
