MULTI-LUMEN EPIDURAL-SPINAL NEEDLE The needle of the present invention is a multi-lumen needle and preferably a dual-lumen epidural-spinal needle. The needle of the present invention is provided with a hub, which allows for attachment of a syringe to one or more of the lumina, or alternatively the attachment of an adapter to which a syringe can be attached. Preferably the lumina have different cross sectional areas. The smaller of the lumina should be of sufficient size to allow a spinal needle, guide wire, or micro-catheter to be inserted through the lumen. The larger of the two lumina should preferably be of sufficient size to allow an epidural catheter, spinal needle or guide wire to be introduced. The needle of the present invention has applications in regional anesthesia, chronic and post operative pain management, cricothyroid puncture, intracerebroventricular puncture and, access and drainage of concealed fluid collections within the body. |
