摘要:
The device relates to a neurostimulator lead extraction tool, which aids in the safe and minimally invasive extraction of an anchored neurostimulator lead. The device is characterized by a handle, barrel, and cutting surface, in that the inner surface of the barrel is advanced over the outer surface of a neurostimulator lead thereby guiding the cutting barrel of the tool through body tissues until the cutting surface is against anti-migration tines of the neurostimulator lead. The device is rotated axially in order to engage the cutting surface. As each set of tines is cut, the cutting surface can be advanced up to the next tine until all the tines are severed. The device and the neurostimulator lead are then removed along the same path of entry, preventing the cutting tool and the lead from migrating into surrounding nerves, blood vessels, and organs thereby avoiding damage to the same.
