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.

L'invention concerne des cathéters à débit élevé ainsi que des procédés de placement et de fabrication associés utiles pour la dialyse et d'autres opérations. Selon l'invention, un cathéter comprend un embout (900) et un conduit (100) généralement allongé. Ce conduit (100) comprend une paroi (400) sensiblement continue et lisse. Ce conduit (100) définit au moins une lumière (500) et comprend une longueur s'étendant de son extrémité proximale (11) à son extrémité distale (15). L'extrémité proximale (11) est couplée à un embout (900) et l'extrémité distale (15) présente une ouverture (200) communiquant avec cette lumière (500). Ce conduit (100) est en forme de cône qui se resserre sur la longueur.
