1. An apparatus comprising:
- a supply assembly configured to maintain and selectively dispense a first precursor functionalized with a first click reactive member and a second precursor functionalized with a second click reactive member, the first and second click reactive members capable of covalently bonding with each othera mixing assembly configured to mix the first and second precursors in a mixing cavity, and,at least one source of UV radiation positioned to irradiate the mixed first and second precursors within the mixing assembly, wherein the at least one source of UV radiation comprises a mixing element comprising a lamp which extends longitudinally through the mixing assembly and the mixing element further includes blades extending radially outward along a length of the lamp.

Abstract
Cross-linked compositions include a first precursor functionalized with a first reactive member and a second precursor functionalized with a second reactive member, the first and second reactive members covalently bonding with each other when exposed to UV radiation. The compositions are useful in a variety of surgical and wound treatment applications.
