Intended Use

The Technomed Europe Kartush disposable surgical stimulators are indicated for tissue dissection and stimulation of cranial and peripheral motor nerves for location and identification during surgery, including spinal nerve roots.

Device Story

Kartush disposable surgical stimulators are invasive, single-patient-use instruments designed for tissue dissection and monopolar nerve stimulation. The device consists of a tip, tapered shaft, handle, and connection pin, typically constructed from stainless steel. It connects to external nerve monitoring equipment via a detachable lead wire with a safety DIN 42802 connector. During surgery, the clinician uses the device to physically dissect tissue while simultaneously delivering electrical stimulation to locate and identify cranial, peripheral motor, or spinal nerve roots. The output is the delivery of electrical current to the target tissue, which helps the surgeon avoid nerve damage by identifying nerve locations. The device is used in a surgical setting by a physician or surgical team. Benefits include improved nerve identification and preservation during dissection procedures.

Clinical Evidence

Bench testing only. Testing included dimensional measurements for current density, impedance tests of tips in saline, material comparison, and dielectric strength testing of shaft and handle insulation. Results confirmed performance equivalence to the predicate device.

Technological Characteristics

Materials: Stainless steel. Energy: Electrical stimulation (monopolar). Form factor: Various tip shapes (needle, elevator, ring dissector, sickle knife, hook) with tapered shaft and handle. Connectivity: Detachable lead wire with DIN 42802 safety connector. Sterilization: Sterile, single-use. Design: Integrated 1-piece material construction for tip, shaft, handle, and pin.

Indications for Use

Indicated for tissue dissection and stimulation of cranial and peripheral motor nerves for location and identification during surgery, including spinal nerve roots, in patients undergoing surgical procedures.

Regulatory Classification

Identification

A surgical nerve stimulator/locator is a device that is intended to provide electrical stimulation to the body to locate and identify nerves and to test their excitability.

Predicate Devices

• Medtronic Xomed Stimulus/Dissection Instruments, Ball-Tip Probes (K031003)

Reference Devices

• Disposable subdermal needle electrode (K990015)
