Abstract

Polymeric compositions, methods, and delivery devices for inhibiting bleeding are disclosed. The method includes applying a dried material topically to a wound site, where the material may include a cross-linked biologically compatible polymer which forms a hydrogel when exposed to blood and where the material may not include an active agent such as thrombin. A spring-loaded delivery device as described herein may be used to apply the dried material.
