Claim 0:
1. An indwelling, urinary catheter, comprising:
a) a urinary catheter tip, comprising:
i) an elongated portion, comprising: parallel sides, a tip end, and a boundary with a lower portion and, further comprising:
A a profile with a non-linear slope from the tip end to the boundary, wherein the slope near the tip end is concave and the slope near the boundary is convex;
B a drainage port comprising: a circumference and a concave indentation that disrupts the continuity of the circumference thereof, the drainage port being centered at the end of the catheter tip, extending through the lower portion, and running parallel to a second lumen; and,

ii) the lower portion, comprising parallel sides, wherein the sides of the lower portion are parallel to the sides of the elongated portion;

b) a tubular urinary catheter body, comprising:
i) a first body end that is in contact with the lower portion of the catheter tip and, comprising: sides that are parallel with one another and with the sides of the elongated and lower portions of the urinary catheter tip;
ii) a second body end;
iii) a first lumen that connects the second body end to the drainage port;
iv) an inflatable, anchor balloon located near and circumscribing the first body end of the tubular catheter body; and,
v) the second lumen that connects the balloon to the second body end;

c) a funnel drainage port that is in liquid communication with the drainage port via the first lumen, the funnel drainage port, further comprising:
i) a check-valve, fitted into the funnel drainage port, the valve comprising:
C a tapered housing having an inside and an outside, comprising:
a) a proximal inlet having a diameter;
b) a distal outlet having a diameter that is wider than the diameter of the proximal inlet; and,
c) opposing notches located on the inside of the housing near the outlet;

D a valve sphere having a diameter larger than the inlet; and,
E an arrester bar that is in contact with the opposing notches of the housing; and,

d) a balloon port that is in liquid communication with the balloon of the tubular catheter body via the second lumen of the tubular body and is configured to receive liquid to inflate the balloon;
wherein:
the balloon is capable of being inflated to a final volume of from 5-75 cc;
the length of the catheter tip is from 4-8 mm as measured from the end of the tip to the balloon, when inflated; and,
the catheter is configured to be an indwelling, urinary catheter.
