Abstract
A tissue punch which is configured to operate by utilizing a spring force to compress tissue between a rotatable cutter blade and a tissue piercing element. The tissue punch is configured such that once the spring force is applied, the cutter blade can be selectively rotated by the user. The rotation of the blade, assisted by the compression from the spring force, causes the cutter blade to cut through the tissue. Three different methods for creating an anastomosis for locating a bypass graft are disclosed. In each method, bypass graft material is installed on a tissue punch and then sutured. Depending on the method, the tissue is punched either before or after the suturing.
