iCE-SG Subcutaneous Electrode Arrays
iCE-SG Subcutaneous Electrode Arrays are intended for temporary (
The iCE-SG Subcutaneous Electrode Arrays are intended for use with recording and monitoring equipment for the purpose of recording electroencephalograph (EEG) signals. The subject device allows for continuous EEG monitoring in the subcutaneous space. The iCE-SG Subcutaneous Electrode Arrays can connect to commonly used electrophysiology systems. The subject device is provided sterile and for single patient use in hospitals by healthcare professionals (HCPs).
A kit includes the following components:
- Preparation box
- Insertion kit box
- Two iCE-SG electrode boxes
Here's an analysis of the acceptance criteria and supporting study for the iCE-SG Subcutaneous Electrode Arrays, based on the provided document:
1. Table of Acceptance Criteria and Reported Device Performance
The document does not explicitly state "acceptance criteria" in a quantitative, measurable format for device performance. Instead, it details various tests to demonstrate safety and equivalence to a predicate device. The "results" column below reflects the outcomes reported for these tests, which were deemed sufficient for demonstrating substantial equivalence.
