An implantable prosthesis for repairing an anatomical defect, such as a soft tissue and muscle wall defect. The prosthesis is configured to reduce the likelihood that an applied force at the repair site, such as due to intraabdominal pressure or tissue shrinkage, can lead to detrimental effects associated with tension at the anchoring locations between the prosthesis and host tissue and/or contraction of the prosthesis. In this regard, the prosthesis may be configured to limit the amount of tension at the anchoring locations caused by the application of a force or pressure to the prosthesis and/or contraction of the prosthesis. Alternatively, the prosthesis may be configured to compensate for contraction of the prosthesis due to tissue shrinkage at the repair site. The prosthesis may be configured to both limit tension at the anchoring locations and compensate for tissue shrinkage. The prosthesis may facilitate a reduction in postoperative discomfort, a recurrence of the defect, or the creation of a new defect associated with tension and/or prosthetic contraction.

A perforation blade according to claim 17, wherein said perforation teeth extend from said burst protection gap to the second end of said base. 19. A perforation blade according to claim 17, wherein said perforation teeth are uniformly spaced. 20. A perforation blade according to claim 17, wherein said perforation teeth have a uniform length. 21. A perforation blade according to claim 17, wherein said base defines a height greater than a length of said first perforation tooth. 22. A perforation blade according to claim 17, wherein said base is formed of spring steel. 23. In combination with a bag cutting device used for cutting a perforated tear line in a bag to form an easy-open corner portion, the corner portion being removable to define a pourer through which contents of the bag are dispensed, the bag having first and second walls with joined opposing side edges, opposing end edges, and a seal line proximate one of the end edges for sealing closed an end of the bag, the improvement comprising a perforation blade mounted within said bag cutting device, said perforation blade comprising: (a) a base formed to span the corner portion of the bag, said base having a first end adapted to extend to the end edge of the bag proximate the seal line, and a second end adapted to extend to one side edge of the bag; (b) a series of closely spaced perforation teeth formed with sa
