1. An extracorporeal valve manifold assembly for use in association with a perfusion pump in percutaneous transluminal angioplasty procedures, the manifold assembly comprising:
- a housing, a fluid passageway defined within the housing;
a plurality of openings disposed in said housing, each of the openings communicating with the fluid passageway and said fluid passageway extending within said housing in a loop to interconnect all of said openings together, one of said openings constituting an inlet to said manifold assembly and another, opposite one of said openings constituting an outlet from said manifold assembly;
said manifold assembly further containing a plurality of discrete valve assemblies, said valve assemblies being disposed in said housing along said fluid passageway such that each said valve assembly is disposed generally between adjoining openings of said housing;
each of said valve assemblies forming an individual check valve to define a plurality of discrete fluid pathways, whereby flow of fluid directed into said manifold assembly via said inlet is directed through said fluid passageway to a fluid receiving component, and flow of fluid from a fluid providing component to the manifold assembly is directed through said fluid passageway and out of said manifold assembly via said outlet.

Abstract
A check valve manifold assembly contains multiple inlet and outlet ports extending through a housing into a fluid passageway. The fluid passageway interconnects the various ports, and the housing further contains multiple check valves, one such valve being associated with each of the ports. When used with an active perfusion pump, the manifold system permits easy and proper perfusion of the patient at high pressures.

- 10. Manifold apparatus for channeling flow of body fluids, such as blood, from an inlet to an outlet of said manifold apparatus while passing the fluid through at least one pumping means of multiple pumping means associated with the apparatus, said manifold apparatus comprising a housing having an inlet, an outlet and two ports disposed in said housing between said inlet and outlet thereof, each of said ports being adapted for fluid communication with one of said multiple pumping means, said housing further having an interior fluid chamber defining a fluid flowpath, the fluid chamber having a plurality of valve assemblies disposed therein such that one valve assembly is located along said fluid flowpath between adjoining ones of said housing inlet, outlet and ports, said valve assemblies each defining a check valve, said check valves operating in response to a pressure differential within said manifold apparatus created by said multiple pumping means to separate said fluid flowpath into two, separate fluid subflowpaths in fluid communication between said housing inlet and outlet, each of said fluid subflowpaths being in fluid communication with at least one of said ports and one of said multiple pumping means associated therewith.
- 13. A check valve manifold assembly for use in an active perfusion pumping system having at least two perfusion pumps, the manifold assembly comprising an inlet, an outlet and at least two interconnecting ports which allow for the passage of body fluids in and out of said manifold assembly to and from the perfusion pumps, the inlet being adapted to receive a connection from a blood supply source, the outlet being adapted to receive a connection from a treatment catheter inserted into the patient, the manifold assembly having a fluid passageway which interconnects said inlet, said outlet and two pumping ports together in fluid communication, said manifold assembly further including a plurality of check valves disposed at predetermined locations along said fluid passageway said check valves being located in said fluid passageway between adjoining ones of said inlet, outlet and pumping ports, said check valves cooperating to define distinct fluid flowpaths of equal extent extending between said inlet and said outlet, each of said fluid flowpaths intersecting and communicating with one of said two pumping ports to thereby permit body fluid flow into said manifold assembly via said inlet and out of said manifold member via said outlet, while preventing body fluid flow out of said manifold assembly via said inlet.
