Abstract

High flow rate catheters, and related methods, are useful in dialysis and other procedures. A catheter according to the invention comprises a hub (900) and a generally elongated conduit (100). The conduit (100) has a substantially continuous and smooth wall (400).
The conduit (100) also defines at least one lumen (500) and has a length extending from a proximal end (11) to a distal end (15) of the conduit (100). The proximal end (11) is coupled to a hub (900) and the distal end (15) has an opening (200) in communication with the lumen (500). The conduit (100) has a conical shape which tapers along the length.
