TRI-CURVE ELONGATE MEDICAL DEVICE

摘要

An embodiment of an elongate medical device may comprise a shaft body having a distal end portion and a proximal end portion and three or more deflection wire assemblies, each deflection wire assembly comprising a flat wire coupled to the distal end portion and configured to deflect the distal end portion. Each flat wire may have a respective length defining a respective deflection radius, wherein each deflection radius is different.
