Patent ID: 7704239

Claim:
A catheter hub for a catheter to be implanted, for securing extension tube assemblies to a proximal end thereof for fluid communication with respective lumens of the catheter, comprising: a generally annular body having: a first port; a second port at which the catheter hub is connectable to the catheter proximal end, the second port fluidly communicating with the first port through a first conduit, wherein fluid flowing into the first conduit from the first port turns within the annular body at an angle of greater than approximately 135 degrees between the first port and the second port; a third port fluidly communicating with the second port through a second conduit, wherein fluid flowing into the second conduit from the third port turns within the annular body at an angle of greater than approximately 135 degrees between the third port and the second port; and a fourth port fluidly communicating with the second port, wherein the fourth port and the second port are generally co-axial, wherein the first, second, third and fourth ports have respective lengths just sufficient to enable connection thereof to respective ends of the catheter and extension tube assemblies, whereby the body may be compact in size.
