Intended Use

The ISIS MER System / Elekta MER System is intended to be used during neurosurgery to record and stimulate brain motor and sensory neurons to aid in the placement of depth electrodes.

Device Story

The ISIS MER System / Elekta MER System is a neurosurgical device used for extracellular recording and deep brain stimulation. It features an integrated neurostimulator that delivers impulses to brain tissue; it supports simultaneous recording and stimulation across up to five channels, with a sixth channel available for EMG recording for patient surveillance. The system is operated by neurosurgeons during neurosurgical interventions to assist in the precise placement of depth electrodes. By providing real-time feedback on neuronal activity and allowing for stimulation, the device aids the surgeon in identifying target brain regions, thereby facilitating accurate electrode positioning and potentially improving surgical outcomes.

Clinical Evidence

No clinical data provided; substantial equivalence is based on technological characteristics and functional comparison to predicate devices.

Technological Characteristics

The system is a multi-channel neurophysiological recording and stimulation device. It supports up to five channels for MER (microelectrode recording) and stimulation, plus one EMG channel. It functions as a depth electrode interface. Technical details regarding materials, specific software architecture, or sterilization are not provided in the source document.

Indications for Use

Indicated for use during neurosurgery to record and stimulate brain motor and sensory neurons to aid in the placement of depth electrodes.

Regulatory Classification

Identification

A depth electrode is an electrode used for temporary stimulation of, or recording electrical signals at, subsurface levels of the brain.

Predicate Devices

• Axon Guideline System 3000A (K970943)
• Keypoint / Leadpoint system (K944574)
