Method for making a multi-lumen epidural-spinal needle and tip and stock configuration for the same

摘要

The present invention discloses a method for producing a multi-lumen needle suitable for administrating spinal anesthesia. The method will provide a needle that will allow the simultaneous administration of spinal and epidural anesthetic from a single site. A preferred needle made by this method can optionally be made with a stock configuration which has means for holding a catheter during the insertion of a spinal needle and is configured so as to provide gripping sites to assist in positioning the needle. The preferred needle of the present invention has a lumen which can serve as a spinal introducer. The introducer lumen sheaths the spinal needle until the spinal needle is in the epidural space. This assures that the spinal needle will not be bent or fractured in use by impingement with bone or hard tissue.
