Intended Use

The Stryker RF Multi-lesion Generator, in combination with the Stryker RF Electrodes and Cannulae are intended for coagulation of soft tissues in orthopedic, spinal, and neurosurgical applications. Examples include, but are not limited to: Facette Denervation, Percutaneous Chordotomy/Dorsal Root Entry Zone (DREZ) Lesion, Trigeminus Neuralgia, Peripheral Neuralgia and Rhizotomy. The Stryker RF Multi-Lesion Generator in combination with a Smith & Nephew SPINECATH™ & Acutherm™ catheters are intended for coagulation and decompression of disc material to treat symptomatic patients with annular disruption of contained herniated discs.

Device Story

Bipolar and monopolar high-frequency electrosurgical system; utilizes RF generator, electrodes, cannulae, and footswitch. Device delivers temperature-controlled RF energy to targeted tissue, inducing cellular necrosis for coagulation or decompression. Enables concurrent treatment of multiple tissue areas to reduce procedure time. Used in clinical settings by physicians for pain management and neurosurgical applications. Output allows clinicians to create defined lesions on nerve fibers or tissue; clinical decision-making guided by real-time thermal treatment monitoring. Benefits include targeted tissue ablation and reduced procedure duration.

Clinical Evidence

No clinical data provided; substantial equivalence based on technological comparison to predicate devices.

Technological Characteristics

Bipolar and monopolar high-frequency electrosurgical generator. Features temperature-controlled RF energy delivery. System includes RF generator, footswitch, electrodes, cannulae, neutral electrodes, and adapters. Connectivity includes specialized cables for electrodes and intradiscal catheters.

Indications for Use

Indicated for patients requiring soft tissue coagulation in orthopedic, spinal, and neurosurgical procedures (e.g., denervation, chordotomy, neuralgia, rhizotomy) and patients with symptomatic contained herniated discs with annular disruption.

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.
