Patent ID: 7520885

Claim:
A system for preparing a graft vessel for anastomosis, comprising: a functional package comprising a tray in which at least one recess is defined, wherein at least one said recess is configured to hold a biocompatible fluid, and wherein a channel is defined in said tray; an assembly held in at least one said recess, said assembly comprising a crown having a lumen therein and an anastomosis device connected to said crown, said anastomosis device including one or more tines; and a poke-through tool including a membrane and a tensioning member wherein the tensioning member tensions the membrane in a substantially flat configuration; wherein said channel is generally longitudinally aligned with said crown, wherein said poke-through tool is slidable along said channel relative to said anastomosis device to penetrate said tines through said membrane and thereby push the graft vessel onto said tines, and wherein said membrane retains substantially the same shape during penetration of said tines through said membrane; and wherein, when said poke-through tool is positioned in said channel, said membrane is oriented substantially perpendicular to the longitudinal centerline of said anastomosis device, and said channel constrains motion of said poke-through tool to translation parallel to said longitudinal centerline of said anastomosis device.
