1. A manifold for coupling a pressure/suction source and a plurality of diagnostic or therapeutic substance sources to a medical device adapted for use of the diagnostic or therapeutic substances, the manifold comprising:
- a housing including a plurality of ports including a first port, the first port in fluid communication with a bifurcated bore including a first branch and a second branch, wherein the first branch of the bifurcated bore includes a check valve; and
valve means having a first position, a second position, and a third position, wherein the first position is adapted for infusing a first substance to the medical device, the second position is adapted for flushing the manifold, and the third position is adapted for draining fluid from the medical device.

Abstract
A number of devices are illustrated for providing a manifold that can simply and selectively couple a number of different therapeutic and diagnostic elements to a catheter or other medical device. Some examples include devices having sliding actuators, rotary actuators, button actuators, or combinations thereof, for easily changing the valve scheme and fluid pathways within a manifold.

9. A manifold for controlling which of several ports is coupled to a medical device, the manifold comprising:
-
a port for coupling to a pressure/suction device; a port for coupling to a diagnostic or therapeutic substance source; a port for coupling to a saline/waste line; a port for coupling to the medical device; and a main valve including a rotating actuator having a number of bores therethrough and a housing providing a number of bores between the ports and the rotating actuator; wherein the rotating actuator and the bores selectively provide; a first fluid path coupling the pressure/suction port to the substance source port and the medical device port when the rotating actuator is in a first position for infusing the substance into the medical device, wherein the first fluid path further includes a first check valve for preventing aspiration from the medical device; a second fluid path coupling the pressure/suction port to the saline/waste line port when the rotating actuator is in a second position for flushing the manifold and pressure/suction device; and a third fluid path coupling the pressure/suction part to the medical device port when the rotating actuator is in a third position for aspirating fluid from the medical device, wherein the third fluid path includes the first check valve and wherein the rotating actuator is moved from the first position to the third position such that the first check valve, when in the third fluid path, operates to prevent injection of fluid to the medical device. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A manifold for selectively controlling fluid communication of several ports with a medical device, the manifold comprising:
-
a housing having a plurality of ports and a plurality of bores, wherein a first port is in fluid communication with a first bore, a second port is in fluid communication with a second bore, and a third port is in fluid communication with a bifurcated third bore, wherein a first branch of the bifurcated third bore includes a check valve and a second branch of the bifurcated third bore is without a check valve; and an actuatable valve for selectively controlling fluid communication among the plurality of bores. - View Dependent Claims (19)
