1. A composition comprising:

  • a biocompatible polymer comprising;

    a first monomer selected from a group consisting of aminopropyl methacrylamide, aminoethyl methacrylamide, aminoethyl methacylate, aminopropyl methacylate, N-(3-methylphridine)acrylamide, N-(2-(4-aminophenyl)ethylacrylamide, N-(4-aminobenzyl)acrylamide, N-(2-4-imidazolyl)ethyl)acrylamide, and combinations thereof; and

    a second monomer including an acrylate, acrylamide, a derivative thereof, or a combination thereof;

    a solution with a non-physiological pH; and

    a visualization agent;

    wherein the biocompatible polymer is soluble in the solution and insoluble at a physiological pH at a treatment site;

    wherein the visualization agent is an iodinated compound, barium sulfate, tantalum, superparamagnetic iron oxide, gadolinium molecules or a combination therefore.
