  • Insulated skull pins
    Patent number: 6379362
    Abstract: A skull pin has a ceramic insulating portion between a titanium driving portion and a titanium tip portion. The driving portion of the skull pin terminates in a sleeve, and the ceramic insulator with a solid cylindrical shape is received such as with a press fit in the sleeve. The preferred ceramic material is zirconia. The tip portion has an opposing outer sleeve which receives the distal end of the ceramic insulator such as with a press fit. The ceramic insulator is believed to reduce or eliminate a burning sensation felt by patients during Magnetic Resonance Imaging (MRI), which may be caused by transmission of high (radio) frequency electrical signals through the prior art skull pins.
    Type: Grant
