Mechanical Properties of Polymeric Emboli for Occlusion of Blood Vessels

Investigations of the formation of solid emboli in an aqueous medium of biocompatible solutions of polymers were carried out. Approaches to the production of solid samples for tensile and compression tests were developed and their mechanical properties were studied. It is shown that the ultimate compressive and tensile strength of emboli formed in an aqueous medium slightly decreases with increasing time of aging in water and increases markedly with increasing polymer concentration in the embolizing solution. All the tested compounds exhibit strength sufficient to not be destroyed by the action of blood flow.
