Neurological stimulation lead extension
First Claim
1. A medical lead extension comprising:
- a proximal end configured for attachment to a neurological device;
a distal end formed to receive an implanted medical lead and electrically couple the implanted medical lead to the neurological device, wherein the distal end forms a laterally accessible channel sized to receive the implanted medical lead; and
a set of electrical contacts disposed within the channel to electrically couple to corresponding electrical contacts disposed along a major axis of an inserted end of the implanted medical lead, wherein the laterally accessible channel allows the medical lead to be laterally placed in the channel such that the set of electrical contacts electrically couple to the corresponding electrical contacts disposed along a major axis of the inserted end of the medical lead when the medical lead is mechanically secured within the channel.

Abstract
The invention is directed to neurological lead extensions without set screws, set screw blocks, or set screw inserts. Such elimination of set screws, blocks and inserts can reduce the amount of metal and ferromagnetic material in the extension. The neurological lead extension may include a proximal end configured to couple to a neurological device and a distal end configured to couple to an implanted neurological lead. A set of electrical contacts are disposed in proximity to the distal end to provide electrical contact to an inserted end of the implanted neurological lead. Various elements and structures are described which can mechanically secure the inserted end of the implanted neurological lead to the distal end of the extension.
