SAGE
SAGE near-field low-frequency electromagnetic technology is a cost effective, accurate, and easy to use 3D tracking and navigation platform for placement of catheters, stylets, guidewires, needles, and other medical devices.
SAGE employs one or more microcoils incorporated into a medical device, which are electrically driven to create a low-frequency magnetic field. A sensor module containing an array of magnetic field sensors is located outside the patient, and plugged into a laptop or other computer system with a display. Measurements from the sensors are fed into a complex algorithm that calculates the position and orientation of the medical device, and the location information is displayed and updated in realtime.
The low-frequency signal from the SAGE coil is essentially immune to interference from nearby metals or other magnetic materials, allowing movement of the sensor module or patient without any recalibration of the system.
SAGE is easy to implement – a small SAGE coil is placed in or on the device to be tracked, and a sensor module is placed on the patient. The sensor module plugs into a laptop or other computer driven display system via USB. SAGE can be added to a variety of devices, including catheters, stylets, guide wires, probes, needles, and other devices.
SAGE Features & Benefits
- SAGE is an Electromagnetic Navigation platform for precise, real-world targeting: The 3D location of one or more SAGE coils can be tracked in real-time. Tracing depths of up to 30 cm are possible with emitter coils as small as .010″ diameter.
- Accuracy: The SAGE System delivers high-accuracy tracking in distorted environments, enabling reliable navigation to small, hard-to-reach targets—particularly in the lung and other soft tissue applications. By combining a distortion-resistant EM system with miniaturized, flexible SAGE coils, it extends navigation deeper into the anatomy than conventional systems allow.
- Multiple Targets: A key differentiator is simultaneous multi-target tracking—allowing physicians to track tools, targets, and reference points at the same time. The Sage system can track multiple coils (up to 8) in real time. Allowing the use of reference coils for better visualization. SAGE emitter coils can be as small as 0.01″ diameter.
- Interference Free: Due to the low frequency system, there is virtually no interference from external metal (ferrous and non-ferrous) objects or magnetic sources. It can even function inside of a needle!
- Movement: Sensor module (detector) can be moved while the system is in use without requiring re-calibration.
- Interface: USB Interface from sensor module to display (laptop, tablet, phone). Capable of wireless connection between the disposable medical device and the sensor module.
- No calibration required at bedside before or during the procedure.
- Cost: The SAGE system is more cost effective than any other navigation systems currently available. The emitter coils in the disposable device are significantly lower cost than any other EM navigation system and are designed for high volume manufacturing.
- Multiple Applications: SAGE technology can be applied to catheters, stylets, guidewires, probes, needles, and other medical devices or tools.
- Potential Uses: SAGE tracking could be useful in PICC and CVC placements; GI tube and device placements; Peripheral Lung Navigation; Interventional Oncology; Needle Guidance; Vascular Navigation; Nerve-block anesthesia; biopsy; endoscopy, cardiology device placement, orthopedics, and other procedures.
