1. A method of constructing an anastomosis between a first vessel and a second vessel comprising:
- providing a device comprising an electrode for creating an opening in a vessel and a seal having a plurality of seal members for sealing the opening in the vessel;
positioning the electrode adjacent a wall of the first vessel;
applying sufficient energy to the electrode to form an opening in the first vessel;
delivering the seal into the opening in the first vessel wherein the plurality of seal members are in a stacked first configuration;
rotating a handle coupled to a shaft and to the seal members in a first direction to radially spread the plurality of seal members about an axis of the opening into a fanned-out second configuration to seal the opening;
attaching the second vessel to the first vessel to form the anastomosis;
rotating the handle in a second direction to arrange the plurality of seal members in the stacked first configuration; and
removing the seal from the opening.

6. A method of constructing an anastomosis between a first vessel and a second vessel comprising:
- providing a sealing assembly comprising a seal and a shaft wherein the seal includes a plurality of seal members;
positioning the shaft so that at least a portion of the shaft is positioned within the second vessel;
creating an opening in the first vessel;
inserting the seal through the opening wherein the plurality of seal members are in a stacked first configuration;
rotating a handle coupled to the shaft and to the seal members in a first direction to radially spread the plurality of seal members about an axis of the opening into a fanned-out second configuration to seal the opening;
attaching the second vessel to the first vessel to form the anastomosis;
