Devices, systems and methods for fixation of tendon to bone are described. An exemplary surgical implant is a modified bone anchor that is able to grasp the tendon and hold it firmly in a bone tunnel. Once deployed, the anchor delivers lateral compression to the tendon, providing direct tendon to bone compression to facilitate healing. The anchor has different versions which allow it to be attached to the tendon prior to insertion into the bone tunnel, or be inserted between tendon arms when the surgical procedure dictates. The resulting tendon to bone compression allows for the firm fixation in a manner markedly simpler than traditional techniques. A modification of this anchor can also allow the anchor to grasp and hold suture. This variation facilitates the technique for knotless rotator cuff repair.

A sanitary napkin for placement in a crotch portion of an undergarment of a wearer having a longitudinal axis and being further characterized by having a preferential bending zone extending obliquely in relation to the longitudinal axis, each preferential bending zone being located solely in an end region and does not extend into a central region of the napkin. The preferential bending zone may be created by mechanically embossing the surface of the sanitary napkin to locally densify the absorbing materials of the article. The preferential bending zone causes the end regions of the sanitary napkin to resist lateral compression forces exerted by the thighs of the wearer and thereby prevents bunching of the article on the undergarment. The central region 70 of the sanitary napkin conforms to the wearer's body providing greater comfort for the wearer of the napkin.
