Horizon 3.0 TMS Therapy System is indicated for the treatment of Major Depressive Disorder in adult patients who have failed to achieve satisfactory improvement from prior antidepressant medication in the current episode, as well as an adjunct for the treatment of adult patients suffering from Obsessive-Compulsive Disorder (OCD).

The Horizon® 3.0 TMS Therapy System is a computerized, electromechanical medical device that produces and delivers non-invasive, magnetic stimulation rapidly alternating, or pulsed, magnetic fields to induce electrical currents directed at spatially discrete regions of the cerebral cortex. This method of cortical stimulation by application of brief magnetic pulses to the head is known as Transcranial Magnetic Stimulation. ("TMS"). The Horizon® 3.0 TMS Therapy System is a non-invasive tool for the stimulation of cortical neurons for the treatment of Major Depressive Disorder in adult patients who have failed to achieve satisfactory improvement from prior antidepressant medication in the current episode, as well as an adjunct for the treatment of adult patients suffering from Obsessive-Compulsive Disorder (OCD). The Horizon® 3.0 TMS Therapy System is used for patient treatment by prescription only under the supervision of a licensed physician. It can be used in both inpatient settings, including physicians' offices, clinics, and hospitals. Horizon® 3.0 TMS Therapy System is an integrated system consisting of a combination of hardware, software, and accessories.

The Magstim D702 coil is a stimulating coil intended for use with the Magstim® 2002 Stimulating Unit or the Magstim® Rapid2 Stimulating Unit for the purpose of peripheral nerve stimulation for diagnostic purposes. The coil is an accessory to the Magstim ® 2002 Stimulating Unit, and the coil is an accessory to the Magstim® Rapid2 Stimulating Unit.

The Magstim D702 coil is designed for use with the Magstim 2002 stimulator or the Magstim Rapid2 stimulator. The Magstim D70 coil provides a method of non-invasively delivering its output to a target such as the peripheral nerves. Discharge current through the coil generates a brief, high intensity magnetic pulse. When the coil is applied to a conductive medium such as the human body, eddy currents are produced in the medium by electromagnetic induction. This stimulation method enables deep and otherwise inaccessible nerves to be stimulated easily and relatively painlessly. In addition, no skin preparation is required and stimulation can be achieved through clothing. The coil is a non-sterile reusable device intended for multipatient use. The coil is transportable and is intended to be used in a laboratory, consulting room or equivalent environment. The coil is intended for short-term patient contact where single or cumulative contact does not exceed 24 hours.

The Neurosign Avalanche nerve monitor is intended to help surgeons locate, identify, and preserve cranial motor nerves during surgery. The intended uses of the Neurosign Avalanche Motor Nerve Monitor is: 2 channel thyroidectomy and parathyroidectomy, mastoidectomy parotidectomy, mastoidectomy, skull-base 4 channel

The Neurosign Avalanche Motor Nerve Monitor is a 2 or 4 channel nerve monitor for intraoperative use in general surgery, skull-base surgery and ENT. The Neurosign Avalanche Motor Nerve Monitor allows the user to detect motor nerves and to check their integrity by acquiring the compound muscle action potentials at the target muscles. The acquired signals are processed by the monitor and displayed as waveforms on the monitor screen and played back acoustically via the built in audio amplifier and loudspeaker. The Neurosign Avalanche Motor Nerve Monitor provides additional information to the user, helping the surgeon to locate nerves by using an electrical stimulator. The sound is independent from the waveform display on the monitor's screen. The displayed waveforms can be printed along with the patient information via the built in thermal array printer, or as a generated report in Word format.

The Magstim® Double 70mm Air Film™ Coil is a stimulating coil solely intended for use with the Magstim® Rapid2 Stimulating Unit for the purposes of peripheral nerve stimulation. The coil is an accessory of the Magstim® Rapid2 Unit.

The Magstim Double 70mm Air Film Coil is an air-cooled coil intended for peripheral stimulation of the nerves. This coil enables deep, and otherwise inaccessible, nerves to be stimulated easily and relatively painlessly. Additionally, no skin preparation is required and stimulation can be achieved through clothing. The Magstim Double 70mm Air Film Coil is for use by, or under the supervision of, a medical practitioner only.

Non-invasively monitoring of the laryngeal nerves during thyroid surgery, and of the Xth cranial nerve during skull-base surgery.

The Neurosign® Laryngeal Electrode, which was specially developed for use with the Neurosign® 100, 400 and 800 models, consists of: a single-use electrode constructed from medical-grade inks suspended in a polyester substrate; a connector made of polypropylene; and a cable assembly. The electrode is available in two sizes to suit different sexes and age groups. The 6/7mm electrode should be used with a 6 or 7mm endotracheal tube; the 8/9mm electrode should be used with an 8 or 9mm tube. The cable assembly is available separately and will have a long life if it is not abused and is stored appropriately. Using the laryngeal electrode lowers the risk of damage to the laryngeal or Xth cranial nerve (the Vagus nerve) during thyroidectomy or parathyroidectomy and, since it is noninvasive, it also lessens the risk of infection during the monitoring procedure.

This submission is being made because the Magstim Company, referred to as Magsimil, has mounted the device marked under K992911 to replace the external laptop interfaced with the main system via a computer with an embedded interest. Previously, a laptop interfaced with the main bespoke touch-screen display moduler. The new system architecture means that unnt via the I CNCD I V or of also ove controlling the system, resulting in it no longer there is dedicated, in-nouse, so Microsoft Windows operating environment.

To locate and identify cranial motor nerves during ENT and intra-cranial procedures.

The Neurosign 400 is an EMG machine and nerve stimulator. The machine consists of a central control unit to which a pre-amplifier pod and intramuscular, or surface, electrodes are attached for EMG recordings. Additionally, connected to the main unit is a stimulator pod to which a stimulating probe, which delivers current to nerve tissue, may be connected. The Neurosign 400 is intended to monitor and to stimulate cranial motor nerves. Cranial motor nerves are monitored by detecting EMG activity in the muscles they innervate.

To locate and identify cranial and peripheral motor nerves during surgery, including spinal nerve roots.
