ABSTRACT:
An epidural catheter which combines the benefits of the open-end and closed-end three lateral holes type catheters. The epidural catheter of the present invention is designed to include an end hole and a plurality of lateral holes epidural catheter. The combined end and multiple lateral holed epidural catheter of the present invention includes seven holes within a 1.5 cm head. The holes are positioned along the head such that one hole is provided at the tip, three lateral holes are circumferentially arranged about the head at approximately 1 mm from each other, and three additional holes are axially displaced from one another by approximately 4 mm. All the holes are within the 1.5 cm from the tip. The radius of each of the lateral holes is the same, thus, the anesthetic solution stream is the same from each hole.
