A shape sawing system for sawing lumber pieces from a curved cant. The modules include a top, product conveying surface and a bottom, sprocket-driven surface. A plurality of particles are distributed in the host material, with at least one particle disposed with an effective mass and a radius that minimize scattering of the electrical charge carriers for the at least one prespecified Fermi level energy of peak charge carrier mobility. Vessel occlusion fasteners may occlude the target blood vessel prior to the anastomosis procedure. The devices provide for releasable yet reliable connection between the fishing-pole mount and the jigging mechanism and allow communication of movement of the jigging mechanism to be communicated to the fishing-pole mount and, thus, to the fishing line.
