SENTIO™ MMG
Defining a new era through a first of its kind digital Nerve Assessment Technology, that offers a solution to the challenges of EMG for intraoperative neuromonitoring.1-4
SENTIO™ MMG is intended for use in surgical procedures to assist in locating and mapping motor nerves through the use of mechanomyographic (MMG) signals and electrical stimulus of nerves. The device provides information directly to the surgeon to help assess a patient’s neurophysiologic status by measuring and comparing MMG signals throughout a surgical procedure.
SENTIO™ MMG provides:
- The ability to assess real-time nerve status.
- Accelerometer-based sensors, eliminating the risk of needle stick injury.
- A direct relationship between stimulation current and distance to the nerve.5
- Confirmation of nerve location with a high degree of Sensitivity and Specificity (97.1 Sensitivity and 84.1 Specificity). 6
- Improved procedural efficiency, while reducing overall cost of care.6,7
Features & Benefits
Sensor Technology
- SENTIO MMG sensors are simple and fast; no skin preparation is required.6
- Sensors have a peel-and-stick application and require fewer procedural steps than needle electrodes.6
- Sensor preparation does not require the patient to be under anesthesia, which facilitates sensor application in the pre-operative setting.
- Sensors eliminate patient discomfort and the healthcare risk associated with needle electrodes.1
Surgeon Driven Technology
- SENTIO MMG is a surgeon-directed technology that can be controlled from the sterile field and does not require a technician for interpretation of results.3
- The user-friendly display allows for real-time surgeon interpretation. Since SENTIO MMG is surgeon-directed, there is no hand-off of information. The surgeon is in control.
Signal to Distance Relationship
- MMG can indicate the presence of a nerve within 2 mm with a high level of confidence (>97.1% sensitivity and 84.1% specificity).5
- MMG can confirm the absence of nerves within 6 mm with a high level of confidence (97.9% NPV).5
High Signal to Noise Ratio
SENTIO MMG is less susceptible to electrical noise, with a high signal-to-noise ratio, ultimately reducing the likelihood of false-positive events commonly associated with EMG technology.3
Decompression Analysis
- SENTIO MMG is creating a new category with “Decompression analysis”.
- SENTIO MMG gives surgeons the ability to quantify the level of decompression performed through software analytics.
Small Footprint
SENTIO MMG technology employs a tablet that virtually eliminates the need for OR floor space often consumed by traditional IONM technologies and carts.
