Abstract
A catheter for delivering medication from a fluid source to an anatomical site of a patient is provided. The catheter comprises an elongated tube having an outer wall extending between an open proximal end and a closed distal end of the elongated tube and an inner wall coaxially disposed within the outer wall. The inner wall has an inner surface to define a lumen. A plurality of openings are defined in the walls to discharge the fluid from the lumen to the anatomical site. A plurality of ribs having different configurations are disposed on the inner surface to reinforce the catheter to provide kink resistance and to prevent the blockage of fluid flow within the lumen.
