Abstract
A catheter has a distal tip having a primary opening formed as the distal opening formed along the axis of the catheter. One or more secondary openings are formed through a side wall of the catheter proximal of the distal opening. A dissolvable portion made up of a resorbable material is disposed within the one or more secondary openings and aligned with the outer surface of the catheter so that the outer surface of the catheter and outer surface of the dissolvable portion combine to present a substantially smooth outer surface. When the catheter distal tip is arranged in a patient's blood vessel, the resorbable material dissolves, so that the fluid delivered by the catheter can exit the catheter through the primary and secondary openings. In some embodiments the secondary openings can be contiguous with the primary opening.
