1. A method of making a tissue buttress comprising the steps of:
- applying a hydrogel comprising an electrophilic component and a nucleophilic component to at least one of a first jaw and a second jaw of a surgical stapler,allowing the electrophilic component and the nucleophilic component to react to form the hydrogel; and
lyophilizing the hydrogel disposed on at least one of the first jaw and the second jaw of the surgical stapler to form a tissue buttress.
