The summary describes a simple electrical probe for nerve stimulation and explicitly states "Mentions AI, DNN, or ML: Not Found".
No
The device is used to assist in locating and identifying motor nerves during surgery, which is a diagnostic or intraoperative monitoring function, not a therapeutic treatment.
No
The device is a nerve stimulating probe used to provide an electrical path for stimulation, assisting in locating and identifying motor nerves during surgery. It is not depicted as diagnosing a condition, but rather as an accessory to a nerve monitoring unit.
No
The device is described as physical probes (surface electrodes) used to stimulate nerves, which are hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood and tissue donations, derived from the human body, solely or principally for the purpose of providing information concerning a physiological or pathological state, or concerning a congenital abnormality, or to determine the safety and compatibility with potential recipients, or to monitor therapeutic measures.
- Device Function: The Kirwan 41-34XX Series of Disposable Nerve Stimulating Probes are used to stimulate nerves in vivo (within the living body) during surgical procedures. They provide an electrical path to the patient's nerves.
- Lack of Specimen Examination: The device does not examine any specimens derived from the human body. It directly interacts with the patient's nerves.
Therefore, the intended use and function of this device clearly fall outside the scope of In Vitro Diagnostics.

Intended Use / Indications for Use
The Kirwan 41-34XX Series of Disposable Nerve Stimulating Probes are intended to be connected to a nerve monitoring unit, such as the Neurosign 100 Nerve Monitor, which requires a standard 1.5mm DIN 42802 touch proof connector, in order to provide an electrical path by which electrical impulses may pass from the monitoring unit to the patient, thus effecting nerve stimulation to assist its user in locating and identifying motor nerves.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Technological safety and effectiveness is established by the fact that these probes do not contain any new technological risks or characteristics when compared to legally marketed devices offered here as predicates. Their design, materials and function were intended to be, and are virtually identical to the predicates. The exceptions being the handle grip pattern and the probe insulation (where applicable), both were selected to enhance the design without compromising their substantial equivalence in regards to intended use, technological safety and effectiveness and performance. Testing to current dielectric strength and biocompatibility requirements assured that there was no compromise. Their energy source is of course identical. They are manufactured according to established standards with the technological characteristics of each probe listed on its labeling.
There are no applicable performance standards listed for these devices under Section 514 of the Food, drug and Cosmetic Act. Nonetheless, Kirwan 41-34XX Series of Disposable Nerve Stimulating Probes have been tested and manufactured in accordance with prevailing standards and guidelines in order to assure safety and efficacy. Kirwan Disposable Nerve Stimulating Probes have been found to comply with the requirements of the applicable sections within the following standards and guidelines;
- . ISO 10993-1, Biological evaluation of medical devices - Part 1: Guidance on the selection of tests.
- IEC 60601-1, Medical electrical equipment.
- IEC 60601-2-10, medical electrical equipment, Part 2; particular . requirements for the safety on nerve and muscle stimulators.
- ISO 11137 -1/2, Sterilization of health care products requirements for B validation and routine control-radiation sterilization.
Safety and hazard analysis has determined that the hazard conditions for the 41-34XX Series of Disposable Nerve Stimulating Probes range in the low-tomoderate level and for this reason are acceptable.
