Patent ID: 6877713

Claim:
An occluder for occluding at least one collapsible tube comprising: an occluding member; and a force actuator constructed and positioned to bend the occluding member from a first configuration to a second configuration, the occluding member in the first configuration being essentially non-compliant to forces applied to the occluding member along at least one direction and the occluding member in the second configuration being compliant with respect to said forces; wherein at least one end of the occluding member is pivotally attached to a support structure; wherein two ends of the occluding member are pivotally attached to the support structure, and wherein the force actuator is constructed and positioned to apply a force to a surface of the occluding member such that the force is applied at at least one point intermediate said two ends; wherein one of said two ends is pivotally and slidably connected with an occluder blade that is constructed and positioned to occlude the collapsible tube when the occluding member is not subjected to a bending force, and to open the tube allowing fluid flow therethrough when the occluding member is subjected to a bending force.
