1. A manifold comprising:
- a main lumen having proximal and distal ends, a primary injection line connected to the proximal end of the main lumen, a port connected to the main lumen between the proximal and distal ends thereof, a check valve permitting flow from the primary injection line to the main lumen while selectively preventing back flow from the main lumen to the primary injection line and permitting flow from the port to the primary injection line while preventing back flow from the primary injection line to the port.

Abstract
A manifold is disclosed which includes a manifold body that defines a main lumen, a primary injection line and a port. A check valve system is also provided which permits flow from the primary injection line to the main lumen while selectively preventing back flow from the main lumen to the primary injection line and, simultaneously, permitting flow from the port to the primary injection line while preventing back flow from the primary injection line to the port.

22. A fluid manifold comprising:
-
a main lumen having proximal and distal ends, a primary injection line connected to the proximal end of the main lumen, a port connected to the main lumen between the proximal and distal ends thereof, a dual check valve comprising a first check valve disposed in-line between the primary injection line and the main lumen for permitting flow from the primary injection line to the main lumen while preventing back flow from the main lumen to the primary injection line and a second check valve disposed in-line between the primary injection line and the port permitting flow from the port to the primary injection line while selectively preventing back flow from the primary injection line to the port. - View Dependent Claims (23, 24, 25, 26, 27)

28. A manifold comprising:
-
a main lumen having proximal and distal ends, a primary injection line connected to the proximal end of the main lumen, a port connected to the main lumen between the proximal and distal ends thereof, a body comprising a first lumen at least partially disposed in the main lumen and a second lumen connected to the first lumen to form a T-connection and extending at least partially into the port, and a dual check valve comprising a first check valve disposed in the body and between the primary injection line and the main lumen and a second check valve disposed in the body and between the primary injection line and the port. - View Dependent Claims (29, 30, 31, 32)

33. A manifold comprising:
-
a main lumen having proximal and distal ends, a primary injection line connected to the proximal end of the main lumen, a port connected to the main lumen between the proximal and distal ends thereof, a dual check valve comprising a check valve element disposed between the port and both the primary injection line and the main lumen, the dual check valve further comprising a movable body comprising a secondary lumen, the movable body being movable between a first position where flow from the port to the primary injection line causes the valve element to engage the movable body and permit flow from the port to the primary injection line while isolating the main lumen from fluid flow from the primary injection line and the port, the movable body further being movable to a second position where the movable body engages the valve element and isolates the port from fluid flow from both the primary injection line and the main lumen and further where the secondary lumen is in-line with the main lumen and the primary injection line thereby permitting fluid flow between the primary injection line and the main lumen, the port further comprising a second check valve that prevents flow from the main lumen or primary injection line to the port. - View Dependent Claims (34, 35, 36, 38, 39, 40)

41. A manifold comprising:
-
a manifold body, a main lumen extending through the manifold body, the main lumen having proximal and distal ends, a primary injection line connected to the proximal end of the main lumen, a port connected to the main lumen between the proximal and distal ends thereof, a rotatable valve body comprising a first lumen, a second lumen connected to the first lumen to form a T-connection and a third lumen, a first check valve disposed in the first lumen of the valve body and a second check valve disposed in the second lumen of the valve body, the valve body being connected to the manifold body and rotatable between three positions including;
a first position wherein the first lumen is disposed in-line between the primary injection line and main lumen and the second lumen is disposed in-line with port line with the first check valve permitting flow from the primary injection line to the main lumen while preventing back flow from the main lumen towards the primary injection line and the second check valve permits flow from the port to the primary injection line while preventing back flow from the primary injection line and main lumen to the port, a second position wherein the second lumen is disposed in-line with the primary injection line and the first lumen is disposed in-line with the port with the first and second check valves permitting flow from the primary injection line to the port while preventing back flow from the port to the primary injection line, and a third position wherein the third lumen is disposed in-line between the primary injection line and the main lumen. - View Dependent Claims (42, 43, 44)
