Abstract

A modular catheter system. The modular catheter system may include a first tubular member, a first catheter tubing, a second tubular member, a second catheter tubing and a plurality of concentric seals. The first catheter tubing may be disposed within an interior portion of the first tubular member while the second catheter tubing may be disposed within an interior portion of the second tubular member. The first tubular member and the second tubular member are removably attachable to each other. The plurality of concentric seals may encircling the first catheter tubing and the second catheter tubing, and the first catheter tubing and the second catheter tubing form a continuous path when the first tubular member and the second tubular member are removably attached to each other. The catheter system may also be formed as a dual lumen catheter.
