• Attributes: Therapeutic

Intended Use

The Spinecath Intradiscal Catheter is intended for use for the coagulation and decompression of disc material to treat symptomatic patients with annular disruption of contained herniated discs. The Acutherm Decompression Catheter is intended for use for the coagulation and decompression of disc material to treat symptomatic patients with contained herniated discs.

Device Story

System comprises Spinecath Intradiscal Catheter and Acutherm Decompression Catheter; used in Intradiscal Electrothermal Therapy (IDET) and Targeted Disc Decompression (TDD) procedures. Introducer needle transects disc annulus for catheter placement in intradiscal space. System connects to ORA-50S or Smith & Nephew Electrothermal 20S Spine System generators; generators deliver radiofrequency energy to catheters; energy converts to thermal energy for tissue coagulation/decompression. Used by surgeons in clinical settings. Output is thermal energy applied to disc material; intended to treat symptomatic contained herniated discs.

Clinical Evidence

Bench testing only; performance and biocompatibility testing demonstrate substantial equivalence to predicate devices.

Technological Characteristics

Electrosurgical cutting and coagulation device; radiofrequency energy delivery; consists of Spinecath and Acutherm catheters used with external electrothermal generators.

Indications for Use

Indicated for symptomatic patients with contained herniated discs, including those with annular disruption, requiring coagulation and decompression of disc material.

Regulatory Classification

Identification

An electrosurgical cutting and coagulation device and accessories is a device intended to remove tissue and control bleeding by use of high-frequency electrical current.

Predicate Devices

• Nucleotomy Catheter (K013622)
• Spinecath Intradiscal Catheter (K993967)

#### Device Description:

The proposed Intradiscal Catheter System, consisting of the Spinecath Intradiscal Catheter and the Acutherm Decompression Catheter, is used as part of the Intradiscal Electrothermal Therapy (IDET) and Targeted Disc Decompression (TDD) procedures. The procedures require the use of an introducer needle and the ORA-50S Electrothermal Spine System Generator or the Smith & Nephew Electrothermal 20S Spine Generator. The introducer needle transects the disc annulus and assists the surgeon in the placement of the catheters in the intradiscal space. The ORA-50S Electrothermal Spine System Generator or the Smith & Nephew Electrothermal 20S Spine System delivers radiofrequency energy to the catheters where the energy is converted to thermal energy.

### Intended Use:

The Spinecath Intradiscal Catheter is intended for use for the coagulation and decompression of disc material to treat symptomatic patients with annular disruption of contained herniated discs.

The Acutherm Decompression Catheter is intended for use for the coagulation and decompression of disc material to treat symptomatic patients with contained herniated discs.

### Technological Characteristics:

The proposed Intradiscal Catheter System is identical to the oredicate Nucleotomy Catheter (K013622) and Spinecath Intradiscal Catheter (K993967) w

### Substantial Equivalence Information:

Performance testing of the proposed Intradiscal Catheter System demonstrates that it performs identically to the predicate Nucleotomy Catheter (K013622) and Spinecath Intradiscal Catheter (K993967). Biocompatibility testing of the proposed device demonstrates that like the predicate devices, the proposed Intradiscal Catheter System does not pose a substantial biocompatibility risk to patients who undergo an IDET or a TDD procedure. The results of all performance and biocompatibility testing are enclosed.

Dear Mr. Robbins:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls.
