Abstract
An injectable embolization and occlusion solution for the selective closure of organs, their duct systems, or blood vessels, comprises a solution of a prolamine such as zein in a physiologically compatible solvent such as ethanol. The solution is injected into the site to be treated where the prolamine quickly precipitates in the body fluids to occlude the site area.
Claims15

An injectable embolization and occlusion solution comprising prolamine in a physiologically compatible solvent and from 5 to 45 percent by weight of an emulsified, physiologically compatible oil.
An injectable embolization and occlusion solution comprising prolamine in a physiologically compatible solvent and an X-ray contrast medium.
An injectable embolization and occlusion solution comprising prolamine in a physiologically compatible solvent and a radioactive tracer substance.
An injectable embolization and occlusion solution comprising prolamine in a physiologically compatible solvent and a cytostatic agent.
An injectable embolization and occlusion solution comprising prolamine in a physiologically compatible solvent and an antimicrobial compound.
An injectable embolization and occlusion solution comprising prolamine in a physiologically compatible solvent and a specific pancreas inhibitor.
A method for occluding the vascular or duct system of a living organ by injecting into the organ at the site to be occluded a solution comprising 5 to 45 percent by wt/volume of zein in 50 to 96 percent by volume aqueous ethanol at a pH of about 6.5 to 6.8.
