SmartEP is an evoked response testing and diagnostic device, that is capable of eliciting, acquiring, and measuring auditory, somatosensory, and visual evoked potential data, as well as providing nerve stimulation and monitoring.
The intended use of the SmartEP device is to objectively record evoked responses from patients of all ages upon the presentation of sensory stimuli. The product is indicated for use as a diagnostic aid and adjunctive tool in sensory related disorders (i.e., auditory, somatosensory, visual) and in surgical procedures for inter-operative nerve monitoring.
SmartEP is an evoked response system that is capable of eliciting, acquiring, and measuring auditory, somatosensory, and visual evoked potential data, as well as providing nerve stimulation/monitoring.
The feature modifications described in this 510(k) are to incorporate additional/expanded indications to the SmartEP device for somatosensory evoked potential, visual evoked potential, and nerve stimulation testing to the previously FDA cleared indications for auditory evoked potential testing. Specifically, additional hardware and software features have been added to the original SmartEP device system to objectively acquire somatosensory/visual evoked potentials upon the presentation of a somatosensory/visual stimulus, and to provide nerve stimulation/monitoring functionality.
The provided text describes a 510(k) premarket notification for the SmartEP device, seeking expanded indications for Somatosensory Evoked Potential (SEP), Visual Evoked Potential (VEP), and Nerve Stimulation/Monitoring. The core of the information regarding acceptance criteria and supporting studies is based on demonstrating substantial equivalence to predicate devices.
Here's a breakdown of the requested information:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria are implicitly defined by the equivalence of key specifications and intended use to legally marketed predicate devices. The "reported device performance" is a demonstration that the SmartEP's characteristics meet or are comparable to those of the predicate devices. The tables provided (Table E-1 and Table E-2) serve as the primary evidence for this.
