Claim 6:
7. A method for rotatable selection of sites for cannulation through skin of a patient for subcutaneous vascular access, the cannulation site selection method comprising steps of:
subcutaneously implanting an arteriovenous access graft in a body of a patient, the graft including an access region defined by a raised surface on the graft;
providing a template having an inner surface and an outer surface, the template defining an opening for a plurality of zones, each of the plurality of zones configured for receiving a plurality of simultaneous cannulations accessing the graft;
marking the outer surface of the template, the marking defining each of the plurality of zones for use as cannulation sites along the graft;
positioning the template on the skin of the patient adjacent the graft such that the opening aligns with the graft; and
using the marking for selecting a first zone for a cannulation site into the graft such that the cannulation site in the first zone is spaced from and not adjacent to a second zone used for cannulation immediately previously to the first zone.
