The housing defines a throughbore which is dimensioned to receive a tubular member. The at least one clamp member is configured to move between a first position in which the clamp member is positioned externally of the throughbore to allow fluid to flow through a tubular member positioned within the throughbore and a second position in which the clamp member extends into the throughbore and into contact with a tubular member to obstruct fluid flow through the tubular member positioned within the throughbore. ## Claims ### Claim 1 A clamping assembly comprising: a housing including a proximal end portion and a distal end portion, the housing defining a throughbore dimensioned to receive a tubular member; and at least one clamp member pivotally coupled to the housing, the at least one clamp member being configured to move between a first position positioned externally of the throughbore to allow fluid flow through a tubular member positioned within the throughbore and a second position extending into the throughbore and into contact with a tubular member to obstruct fluid flow through the tubular member positioned within the throughbore. ### Claim 2 (depends on 1) The clamping assembly of claim 1, wherein the clamp member is pivotally connected to the distal end portion of the housing. ### Claim 3 (depends on 1) The clamping assembly of claim 1, wherein the clamp member is pivotally connected to the proximal end portion of the housing. ### Claim 4 (depends on 1) The clamping assembly of claim 1, wherein the clamp member is pivotally connected between the proximal and distal end portions of the housing. ### Claim 5 (depends on 1) The clamping assembly of claim 1, wherein the housing further comprises a stop to prevent over-rotation of the clamp member within the throughbore. ### Claim 6 (depends on 1) The clamping assembly of claim 1, wherein the throughbore includes a central segment extending along a portion of the housing which divides into two branch segments. ### Claim 7 (depends on 6) The clamping assembly of claim 6, wherein two clamp members are pivotally connected to the housing such that each of the two branch segments has one of the two clamp members associated therewith for independent movement of the clamp members between the first and second positions to control fluid flow through a portion of a y-shaped tubular member positioned within the respective branch segment of the throughbore. ### Claim 8 (depends on 1) The clamping assembly of claim 1, further comprising a clamp actuator for moving the clamp member between the first and second positions. ### Claim 9 (depends on 8) The clamping assembly of claim 8, wherein the clamp actuator is monolithically formed with the clamp member. ### Claim 10 (depends on 8) The clamping assembly of claim 8, wherein the clamp actuator includes a contoured outer surface to facilitate gripping of the clamp actuator. ### Claim 11 (depends on 8) The clamping assembly of claim 8, wherein the clamp actuator is disposed within a slot formed in a sidewall of the housing. ### Claim 12 (depends on 1) The clamping assembly of claim 1, wherein the housing is a hub of a catheter. ### Claim 13 A fluid control system comprising: a tubular member defining a channel extending therethrough for passage of a fluid; a housing defining a throughbore dimensioned to receive the tubular member; and a clamp member pivotally connected to the housing, the clamp member being positioned and configured to rotate into the throughbore of the housing to compress the tubular member when the tubular member is positioned therein and to rotate out of the throughbore of the housing to uncompress the tubular member when the tubular member is positioned therein. ### Claim 14 (depends on 13) The fluid control system of claim 13, wherein the clamp member is positioned to rotate into the throughbore to a position which is substantially transverse to a longitudinal axis of the throughbore. ### Claim 15 (depends on 13) The fluid control system of claim 13, wherein the clamp member is positioned to rotate out of the throughbore to a position which is substantially parallel to a longitudinal axis of the throughbore. ### Claim 16 (depends on 13) The fluid control system of claim 13, further comprising a clamp actuator for rotating the clamp member into and out of the throughbore of the housing. ### Claim 17 (depends on 16) The fluid control system of claim 16, wherein the clamp actuator is a lever attached to the clamp member. ### Claim 18 (depends on 13) The fluid control system of claim 13, wherein the tubular member is an extension tube of a catheter assembly.
