High flow diffusion catheter
First Claim
1. A catheter for use in the withdrawal and/or delivery of a fluid to a patient, comprising:
- a) an elongate tube body including a wall having inner and outer surfaces, the inner surface forming an axial passageway extending through the body in between a proximal end and a distal end;
b) the distal end of tube body having a rounded tip with a primary port and a plurality of secondary ports, the secondary ports extending through the wall at locations in the body spaced from the primary port and from each other, the primary port and the secondary ports being located within a radius of approximately 180 degrees of the circumference of the distal end;
c) a visual indicator located on at least the distal end in order to indicate the angular position of the distal end of the catheter.

Abstract
A catheter for use in the withdrawal and/or delivery of a fluid to a patient. The catheter has an elongate tube body including a wall having inner and outer surfaces. The inner surface forms an axial passageway extending through the body in between a proximal end and a distal end. The distal end of the tube body has a rounded bolus tip with a primary port and plurality of secondary ports. The secondary ports extend through the wall at locations in the body spaced from the primary port and from each other. The primary port and the secondary ports are located within a radius of approximately 180 degrees of the circumference of the distal end. A visual indicator is located on at least the proximal end in order to indicate the angular position of the distal end of the catheter.

17. A method for positioning a distal end of a venous catheter within the superior vena cava of a patient in a selected angular position, the method comprising:
-
a) guiding a distal end of the catheter to position within the superior vena cava using a preloaded wire stylet, the distal end of the catheter having a rounded tip with a primary port and a plurality of secondary ports, the primary port and the secondary ports located generally within a top half of the catheter; and
b) using the stylet and a visual indicator located along at least the distal end of the catheter to adjust the angular position of the distal end of the catheter adjacent a wall in the superior vena cava with the primary port facing away from the wall in the superior vena cava. - View Dependent Claims (18, 19, 20)
