1. A fluid channel sealing device, comprising:
a fluid channel including a flexible tube with internal walls for conveyance of a fluid;
a blocking element, at least a portion of which is sealingly engaged with the internal walls;
the blocking element being reconfigurable from a first configuration free of any open channels such that fluid is prevented from flowing through the fluid channel; and
a second configuration in which an open channel is established and allows fluid to pass wherein the second configuration is established by applying a deforming force on the blocking element to open a hole in the blocking element, a patency of the hole being maintained while the second configuration is maintained, wherein
the blocking element has first and second parts that remain connected in said second configuration, and
the blocking element is a solid of rotation with an axis of the blocking element aligned with an axis of the fluid channel, and the blocking element is reconfigurable by applying the deforming force crosswise to the axis of the blocking element, between the first and second parts.
