Abstract: A method of and apparatus for sealing access openings into blood vessels using an expandable member in the blood vessel on a control member that extends out through the access opening and an applicator which inserts a preformed sealing material into the access opening over the control member to keep the control member and expandable member centered in the access opening and withdrawing the collapsed expandable member back through the sealing material after the access opening is sealed.

Abstract: 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.

Abstract: A method of repairing a blood vessel having a narrowed portion therein comprising the steps of expanding the narrowed portion of the blood vessel so that the diameter of the blood vessel after expansion is enlarged; and then maintaining an electronegative potential on the interior surface of the expanded narrowed portion of the blood vessel to at least as great as any electropositive potential generated by the blood vessel as a result of the injury to the blood vessel caused by the expansion thereof.

Abstract: A syringe injector for injecting liquids into patients comprising a syringe barrel with a slidable piston therein and a driver slidably extending into the barrel bore from the open end thereof behind the piston, where the driver includes a power supply and drive means operated by the power supply to cause at least a portion of the driver to move relative to the barrel to engage and propel the piston toward the discharge opening in the syringe barrel.

Abstract: A system for injecting fluid into a patient and monitoring the blood pressure of the patient comprising an injector for incrementally injecting the fluid through a delivery tube into the vascular system of the patient at selected prescribed rates with display means and rate indicator means generating an output indicative of the rate of fluid injection connected to the display means for visually displaying the rate at which the fluid is being injected; a blood pressure monitor including transducer means communicating with the vascular system of the patient through the delivery tube on the injector for providing an output indicative of the patient's blood pressure and pressure detector means responsive to the output of the transducer means to generate an output indicative of the systolic and diastolic blood pressures of the patient; and mounting means for selectively mounting the blood pressure monitor on the injector and including connector means connecting the output of the pressure detector means in the bloo

Abstract: Method and apparatus for injecting fluids into patients at a controlled rate from an ampule with a tubular side wall closed at one end with a penetrable plug and a sliding piston in the side wall to force the fluid through an opening in the penetrable member using either a long duration injector with an expelling means to move the ampule piston, drive means for operating the expelling means, and control means for incrementally and successively connecting and disconnecting the drive means to the expelling means or a short duration injector with a spring drive or a fluid pressure drive to move the ampule piston and meter the fluid through a metering device.
