As discussed in Dexter Magnetic Technologies’ whitepaper, “Hermetic Sealing of Magnets in Implantable Medical Devices,” hermetic sealing is a critical component in ensuring the safety and longevity of implantable medical devices that incorporate magnets. These magnets, often made from neodymium-iron-boron (NdFeB), are highly susceptible to corrosion when exposed to moisture, which can compromise the functionality and biocompatibility of the device.
Magnets play an essential role in modern implantable devices, enhancing MRI compatibility, improving drug delivery systems, and enabling advanced sensing capabilities. However, their effectiveness depends on the use of biocompatible hermetic sealing materials and advanced sealing techniques that prevent exposure to bodily fluids. Proper hermetic packaging not only ensures device longevity but also meets stringent medical safety standards such as ISO 10993, which governs biocompatibility testing.
