Abstract
The present disclosure relates to a medical device and methods of using the same. In embodiments, the medical device may be a buttress formed of nucleophilic buttress components and electrophilic buttress components which react to both form the buttress and provide the buttress with self-sealing capabilities after a staple or some other fixation device is placed therethrough, thereby enhancing its hemostatic properties. In other embodiments, the medical device is a hernia patch formed of a fibrous substrate, nucleophilic precursor components and electrophilic precursor components.
