Abstract
A reinforcement device for reinforcing tissues having one or more structural deficiencies includes a longitudinally-extending reinforcing layer for treating the structural deficiency, a plurality of spiked naps distributed across the reinforcing layer and projecting therefrom for adhering to the tissue, and a dissolvable matrix layer covering at least a portion of the reinforcing layer and a portion of the plurality of spiked naps. The matrix layer increases the time before the spiked naps substantially adhere to the tissue, thereby allowing the practitioner additional time to position the reinforcement device.
