Multiple valve single port manifold
First Claim
1. A medical device, comprising:
- a catheter having a plurality of lumens anda manifold wherein the manifold includesa conduit having an entry port;
a plurality of means for connecting the conduit to the plurality of catheter lumens, such that each catheter lumen is capable of being in fluid communication with the entry port;
a plurality of means for controlling access from the conduit to the plurality of catheter lumens, such that each controlling means is capable of independently regulating access from the conduit to its corresponding catheter lumen.

Abstract
The present invention relates to a multiple valve single port manifold for use with a multiple lumen catheter. The inventive manifolds comprise a conduit with an entry port; a plurality of means for connecting the conduit to a plurality of catheter lumens, such that each lumen is capable of being in fluid communication with the entry port; and a plurality of means for controlling access from the conduit to the plurality of catheter lumens, such that each controlling means independently regulates access from the conduit to its corresponding catheter lumen. Because each catheter lumen is independently accessible from the same manifold port, the inventive devices are useful in any medical context where a need exists to independently control access to spatially proximal sites within a patient'"'"'s passageway. For example, practice of the present invention allows a fluid to be delivered to any combination of spatially proximal vessel sites, or more typically, allows multiple balloons mounted on a catheter to be independently inflated and/or deflated during angioplasty procedures.

3. A manifold for use with a multiple lumen catheter comprising:
-
a conduit having an entry port; an elongated shaft for containing a catheter shaft therein; and
,a plurality of valves disposed within the conduit, wherein at least two of the valves have an opened position and a closed position, and include a first channel and second channel formed therein, the first channel aligning with the conduit to provide access through the valve when the valved is placed in the closed position, and the second channel aligning with the conduit to provide access through the valve as well as to fluidly couple the conduit to the elongated shaft when the valve is placed in the opened position. - View Dependent Claims (4, 5, 6, 7, 8, 9)

18. An apparatus for selectively coupling a single supply of fluid to separate first, second and third lumens of a catheter comprising:
-
an intake conduit connectable to the fluid supply; an elongated shaft for containing a catheter shaft therein; a first valve located in the intake conduit and being movable between a closed and opened position, wherein in the closed position, fluid is permitted to pass through the first valve to the downstream side of the intake conduit but is prevented from entering the first lumen and wherein in the opened position, fluid is permitted to pass through the first valve to the downstream side of the intake conduit as well as entering the first lumen; a second valve located in the intake conduit downstream from the first valve and being movable between a closed and opened position, wherein in the closed position, fluid is permitted to pass through the second valve to the downstream side of the intake conduit but is prevented from entering the second lumen and wherein in the opened position, fluid is permitted to pass through the second valve to the downstream side of the intake conduit as well as entering the second lumen; and a third valve located in the intake conduit downstream from the third valve and being movable between a closed and opened position, wherein in the closed position, fluid is prevented from entering the third lumen and wherein in the opened position, fluid is permitted to enter the third lumen. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
