A method and system are provided for visualizing a surgical path for a surgical tool. In one embodiment, roles, document types, and permissions are stored in a 3-D model, such as a matrix or table. The manifold has a number of input openings in a first ordered arrangement at one end connected by passageways to a number of output openings in a second ordered arrangement at the opposite end. Also provided are methods of preparing a graft device and connecting the graft between a first body space and a second body space, such as the aorta and a location on an occluded coronary artery, distal to the occlusion. The elastic member and the guide member are disposed in or substantially the same plane orthogonal to the optical axis, or disposed in planes orthogonal to the optical axis and differing in the direction of the optical axis. The present invention is also directed to methods for making the high protein foodstuff, optionally with a high protein coating.
