Title:
USE OF ABSORPTION MATERIAL TO REDUCE RADIO FREQUENCY-INDUCED HEATING IN EXTERNAL FIXATION DEVICES
Document Type and Number:
WIPO Patent Application WO/2016/126288
Kind Code:
A3
Abstract:
The present invention in general provides methods for reducing RF-induced heating in an external fixation device including at least two bars, at least two clamps and at least two pins; and external fixation devices with significantly lower RF heating at the pins' tips when compared to other external fixation devices.
