A trocar for insertion of catheters into a body wall is described. The trocar comprises a bivalved type tapered tip with a handle attached to each portion of the tapered tip, a tubular member adapted to encircle the rearward portion of the tapered tip and a stylet which is adapted to fit inside both the tubular member and the bivalved tapered tip. This device permits insertion of a flexible tubing catheter into a body member wall for prolonged intermittent access to a cavity beyond the body wall. This device is particularly useful in insertion of cuffed catheters into the abdominal wall. |
