Implantable hernia mesh patches (10) have double like size layers (42, 44) of inert mesh material (46), with an internally positioned loop (72) of a resilient monofilament fiber. One of the layers (42, 44) has a transverse slit (66) for the insertion of a surgeon's finger to facilitate positioning. Also the layers (42, 44) optionally have aligned holes (59) around their peripheries, inside of the resilient monofimalent fiber to prevent sliding or migration. Also, suturelss mesh tabs (62) are formed at spaced locations about the peripheries of the layers to retain the patch in place. Also, the free edges (57) of the top layer (42) are folded back in opposite directions and sewn in place near the fold (56), while still leaving extending free sutureless mesh tabs (62). Also, anchoring spikes (82) made of resilient monofilament fiber are formed about the loop (72), serving an attaching. The layers of the patch can be a 'Gortex' material.
