DEVICE: Cobra® (B006LTE7003PSD52)

A sterile hollow cylinder intended to be inserted orally or nasally into the trachea to provide an unobstructed airway to convey gases and vapours to and from the lungs during anaesthesia, resuscitation, and other situations where the patient is not properly ventilated. The device also has a conducting strip in its distal portion to function as an electrode to monitor the electromyographic (EMG) activity of the laryngeal and vocal cord musculature. The device has a ventilator tube connector, radiopaque strip, and is connected to an appropriate EMG measuring/recording device. This is a single-use device.

A hand-held surgical instrument intended to function as an electrical conductor to locate a nerve during open surgery, and for diagnostic purposes [electromyography (EMG), cortical mapping], by delivering controlled electrical impulses to a specific body site for the measurement of a neural response. It may be in the form of a needle probe or surgical forceps which is attached to an electrical pulse generator. This is a single-use device.

A sterile electrical conducting device designed to be inserted percutaneously into muscle or nerve tissue to detect bioelectrical signal activity. It is a needle-like device (a needle electrode with an electrical connector at the proximal end) that is connected to an electromyograph (EMG) with a dedicated cable/lead. The EMG records the electrical signals and converts them into a readable graph format; it is not primarily intended for nerve stimulation. This is a single-use device.
