The rotation of the blade (16), assisted by the compression from the spring force (86), causes the cutter blade (16) to cut through the tissue (26). Three different methods for creating anastomosis for locating bypass grafts are disclosed. In each method, a bypass graft material (200) is placed on the tissue punch (10) and then sutured together. Depending on the method, the tissue (26) is punched before or after the suturing.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
