1. A system for rotatable selection of sites for cannulation for subcutaneous vascular access, the cannulation site selection system comprising:
an arteriovenous access graft to be subcutaneously implanted in a body of a patient, the graft including an access region defined by a raised surface on the graft;
a template having an inner surface and an outer surface, the template defining an opening for a plurality of zones, each zone of the plurality of zones defining a cannulation site and configured for receiving a plurality of simultaneous cannulations accessing the graft; and
a plurality of visible markings on the outer surface of the template, the markings defining each zone of the plurality of zones for use as cannulation sites along the graft,
wherein the access region of the arteriovenous access graft has a shape that is accessible through the opening of the template and the template is flexible and the opening in the template is ovular such that the template is adapted to be disposed adjacent the arteriovenous access graft after implantation of the arteriovenous access graft with the access region accessible through the opening in the template, and
wherein the markings are used for selecting a first zone from the plurality of zones as a first cannulation site into the graft through the access region such that the first cannulation site in the first zone is spaced from and not adjacent to a second zone of the plurality of zones used for a second cannulation site immediately previously to the first zone.
