Replace the minitrocar partially, stopping 1 cm. short of full insertion. Aim the minitrocar and catheter toward the left inguinal ligament, and angle the minitrocar to a plane as close as possible to that of the abdominal wall. Advance the catheter over the minitrocar down into the abdominal cavity without advancing the minitrocar itself until the catheter meets firm resistance, or until the wings or suture points descend to the skin surface.
