Abstract
A urinary catheter is described that can be retained inside the body for extended periods. A catheter mating device can connect to the catheter to move the catheter inside of the body or remove it from the body. The catheter includes one or more of: (1) a retention portion having an outer cover, an inner cavity, and at least one structure in the inner cavity that exerts outward force on the outer cover, and (2) an extendable flap at the catheter's distal end. The retention portion and/or extendable flap each are configured to retain the catheter in the proper position inside of a user's body.
