ABSTRACT:
A multipurpose ointment (MPOc) in a semisolid-semiliquid form and a multipurpose particle (MPPc) in a solid soft particulate form are prepared by combining a matrix base in a aqueous solution with a liquid oil base and added modifiers and medications to form either an ointment or suspension of particles for endovascular disposition for embolizing abnormal microvascular beds or nidi. The ointment or particles are formed from a albumin (human serum or chicken egg) matrix or equivalent material or combination of the same in an aqueous solution, typically contrast-medium solution, which has been emulsified with a radiopaque oil base such as ETHIODOL, and then heated to modify the mobility, viscosity, deformability, elasticity, surface tension and friction along with the inclusion of medications and modifiers for the desired physical characteristics and biological end effects.
