Abstract
The present invention is directed toward an improved catheter introducer needle capable of introducing a catheter into a body at a deflection angle in the range of 40-75° from the axis of the needle. This invention provides for a continuous perineural placement of a catheter. The present invention is also directed toward an introducer needle/catheter system comprising the needle of the present invention and a catheter extending through the needle such that it extends out beyond the tip of the needle at an angle of deflection in the range of 30-75° from the axis defined by the catheter within the main channel of the needle. This invention is useful in delivering pharmacological agents, such as local anesthetics, to nerves in various regions of the body including, but not limited to, the arms and shoulders.
