Drainage Catheter with One-Way Valve
First Claim
1. A medical device that drains bodily fluid, said device comprising:
- a proximal end and a distal end;
a lumen connecting between the proximal end and the distal end, the lumen adapted to drain fluid from the distal end to the proximal end, the lumen having a fluid inflow port at the lumen'"'"'s distal end and a fluid drain coupling at the lumen'"'"'s proximal end; and
a unidirectional valve adapted for insertion and placement in the lumen, said unidirectional valve that allows for fluid passing from the distal end to the proximal end and obstructs fluid from passing from the proximal end to the distal end.

Abstract
Systems and methods that serve to drain a bodily fluid are provided The medical device includes a lumen connecting between the proximal end and the distal end The lumen is preferably adapted to drain fluid from the distal end to the proximal end The device may also include a pressure sensitive valve adapted for insertion and placement in the lumen The pressure-sensitive valve may be pressure sensitive wherein, when pressure at the inflow port rises to a predetermined threshold, the pressure-sensitive valve opens The lumen may also be configured whereby, when pressure at the inflow port drops to a second predetermined threshold, the pressure-sensitive valve closes In some embodiments, the valve may be unidirectional and not sensitive to any substantial pressure threshold but may open at any substantially non-zero pressure applied in the appropriate direction.

8. A medical device for collection of urine, said device comprising:
-
a receptacle to collect urine; an inlet connected to the receptacle, configured to permit the passage of mine therethrough; and drainage tubing comprising a proximal end and a distal end, the proximal end connecting to the inlet, the distal end comprising a catheter connector, the catheter connector for connecting the drainage tubing to a fluid drain coupling of a Foley catheter, the drainage tubing further comprising a unidirectional valve, said unidirectional valve that allows fluid to pass from the distal end to the proximal end and obstructs fluid from passing from the proximal end to the distal end. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A medical device that drains bodily fluid, said device comprising:
-
a proximal end and a distal end; a lumen connecting between the proximal end and the distal end, the lumen adapted to drain fluid from the distal end to the proximal end, the lumen having a fluid inflow port and a fluid drain coupling; and a pressure-sensitive valve adapted for insertion and placement in the lumen, said pressure-sensitive valve characterized such that, when pressure at the inflow port rises to a predetermined threshold, the pressure-sensitive valve opens, and when pressure at the inflow port drops to a second predetermined threshold, the pressure-sensitive valve closes.
