Intended Use

The maxmorespine Bipolar Electrodes are indicated for the coagulation of soft tissue during open or minimally invasive surgical procedures when used in conjunction with a compatible radio frequency generator. The maxmorespine Bipolar Electrodes have not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures and should not be used for these procedures.

Device Story

The maxmorespine Bipolar Electrodes are electrosurgical accessories used for soft tissue coagulation. The device consists of a reusable handle and shaft, and a sterile, single-use flexible electrode. The device is connected to a compatible radio frequency (RF) generator via a flat plug. During surgery, the physician operates the device using a footswitch to deliver RF energy to the tissue through the electrode tip. The device is used in open or minimally invasive surgical procedures. The output is the coagulation of soft tissue, which assists in achieving hemostasis. The device benefits patients by providing a controlled method for tissue coagulation during surgical interventions.

Clinical Evidence

No clinical data. Bench testing only. Performance evaluated via tissue testing (muscle, kidney, liver) demonstrating equivalence to the predicate. Biocompatibility testing per ISO 10993-1, electrical safety per IEC 60601-1 and IEC 60601-2-2, and sterilization validation per ISO 11135 (SAL 10^-6) were successfully completed.

Technological Characteristics

Bipolar electrosurgical accessory. Components: reusable stainless steel handle/shaft, sterile single-use flexible electrodes. Energy source: external RF generator. Connectivity: flat plug connection. Sterilization: Ethylene Oxide (EO) per ISO 11135. Packaging: ISO 11607-1. No software.

Indications for Use

Indicated for soft tissue coagulation during open or minimally invasive surgery. Contraindicated for tubal sterilization or tubal coagulation for sterilization procedures.

## VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

The maxmorespine Bipolar Electrodes shares indications for use and design principles with the predicate device: joimax Electrosurgical Instruments predicate device (K161378); a Class II medical device that was cleared for marketing in the United States under K161378. The design principles of the maxmorespine Bipolar Electrodes device and the joimax Electrosurgical Instruments predicate device (K161378) are substantially equivalent, consisting of sterile, single use, detachable, flexible electrodes of various lengths, reusable stainless steel guide cannula / shaft that facilitates the flexible electrode to pass through the shaft of the cannula, and a reusable handle that attaches to the guide cannulas on one end and the generator on the opposite end. The subject device and the predicate device also share the same design feature a detachable electrode and cannula / shaft that mount to the handle; both designs allowing for the use of various electrode lengths depending on the physician's needs / surgical approach. Furthermore, the maxmorespine Bipolar Electrodes device and the joimax Electrosurgical Instruments (K161378) predicate device share substantially equivalent design principals of providing a single use, sterile, 'pencil' design in which the electrode is permanently mounted on a fixed male fitting that plugs into the handle; which is connected to a generator that provides power to the electrode.

The performance of the maxmorespine Bipolar Electrodes have been evaluated with tissues of various density (muscle, kidney, and liver) and have been shown to be substantially equivalent to the predicate device.

## VII. CONCLUSIONS

Performance testing on various tissue types (muscle, kidney, liver) has demonstrated that the performance of the maxmorespine Bipolar Electrodes are substantial equivalent to the predicate device (K161378). The nonclinical testing demonstrate that the subject device is safe and substantially equivalent to the predicate device. The performance testing and nonclinical testing demonstrate that the maxmorespine Bipolar Electrosurgical Instruments are substantially equivalent to the predicate device and do not raise new questions regarding the safety and effectiveness as compared to the predicate device (K161378).
