Abstract
Polymeric compositions are described comprising a biocompatible polymer including a biodegradable linkage to a visualization agent and a non-physiological pH solution; wherein the biocompatible polymer is soluble in the non-physiological pH solution and insoluble at a physiological pH. Methods of forming the solutions and polymers are disclosed as well as methods of therapeutic use.
Claims15
A polymer including:
- a biodegradable linkage to a visualization agent wherein the visualization agent is formed from a monomer having at least one aromatic ring and at least one polymerizable moiety,
- wherein the polymer is substantially stable and wherein the polymer is soluble in a non-physiological solution and insoluble in a physiological solution,
- wherein substantially stable is where the polymer is greater than 90% intact after about 1 month after an implantation procedure.
