Thrombosis in a blood vessel is prevented in a patient's body by the steps of positioning an electrically conductive member in an expanded portion of the blood vessel, at a site where the body is exposed to blood platelets, and disposing an electronegative potential generator in or adjacent to the patient's body and connected to the conductive member for maintaining a negative bias on the conductive member. One form of generating the negative bias is by passing microwaves through the patient's body to contact an embedded diode which generates the negative potential. The current density is maintained at about 50 milliamps per square centimeter. |
