Latest Patents

One of Johnston's latest patents is the "Electromagnetic acceleration transducer for implantable medical device." This invention features an electromagnetic accelerometer that includes a rigid shell with a cavity housing two fixed magnets and one movable magnet. The design allows the movable magnet to be suspended between the fixed magnets by magnetic forces. When the accelerometer experiences acceleration, the displacement of the movable magnet induces an electrical current in a surrounding coil of wire. This voltage is proportional to the acceleration, making the accelerometer particularly useful in implantable pacemakers or defibrillators. Additionally, it generates its own voltage in response to acceleration, which can serve as a power source.

Another notable patent is the "Steerable endocardial lead using magnetostrictive material." This invention utilizes magnetically alterable materials, such as magnetostrictive materials, in combination with a suitable substrate and magnetic field. The result is a stylet and lead assembly that can curve in response to a magnetic field, enhancing the functionality of medical leads.
