Abstract
Methods for making bioprosthetic devices made of collagen-based material having collagen amine groups and collagen carboxyl groups are provided. The methods include blocking at least a portion of the collagen amine groups with a blocking agent, activating at least a portion of the collagen carboxyl groups after blocking at least a portion of the collagen amine groups to form activated carboxyl groups, and contacting the activated collagen carboxyl groups with a polyfunctional spacer to crosslink the collagen-based material.
