Abstract
Inventive concepts relate generally to the field of implantable urological devices, and more particularly to compositions that inhibit crystallization of urine components. Described are implantable urological devices including a surface and a crystallization inhibitor composition, the crystallization inhibitor composition including: (a) an inhibitor of urine component crystallization in combination with a biodegradable polymer, or a polyalkene homopolymer or copolymer, or (b) a biodegradable polymer that includes an inhibitor of urine component crystallization, wherein the crystallization inhibitor composition provides controlled release of the inhibitor of urine component crystallization from the surface of the device into a subject. Methods of making the implantable urological devices are also described.
