3D Guidance medSAFE

Medically Compliant: Class 1, Type CF, Defib Proof

Electronics unit with multiple sensor and transmitter options

Guide Medical Instruments with Passive DC Magnetic Sensors

Track multiple miniaturized sensors simultaneously.

Localize in 3D without ionizing radiation.

Guide flexible tools without line-of-sight restrictions.

No "power-line" noise interference.

Navigate catheters, probes, and scopes with low

cost, disposable sensors.

Multiple transmitter options enable use in medical environments

once unsuitable for magnetic tracking.

medSAFE's miniaturized sensors are

routinely deployed in medical

instruments and catheters for

safer and less intrusive tracking

and localization. Here a 1.3 mm

sensor is seen protruding from the

working channel of a bronchoscope.

Sensors with sub-millimeter diameters are available to extend

the reach of catheters and scopes deep into the periphery of

organs and vessels.
