1. A graft closure system for closing a portion of a graft comprising:
a graft having a tubular portion, a lumen and a circumference;
a closure mechanism including at least one closure element extending around the circumference of the tubular portion and attached to the tubular portion, the at least one closure element comprising a resiliently deformable material and having a first, biased, configuration in which the closure element has a generally annular profile and a second, unbiased, configuration in which the closure element has a substantially linear profile; and
a release element engaged with the closure element;
wherein in the first, biased, configuration the closure element holds the tubular portion lumen in an open configuration and in the second, unbiased, configuration the closure element holds the tubular portion lumen in a closed configuration; and
wherein the release element is configured to disengage from the closure element to move the closure element from the first, biased configuration to the second, unbiased configuration and closes the lumen.
