  • MODULAR MEDICAL INJECTION SYSTEM
    Publication number: 20140288501
    Abstract: A medical injection system includes an elongate injection apparatus and an actuator apparatus. The actuator apparatus includes a fitting for coupling the actuator apparatus to a delivery catheter and a reversible gripping means to grip the injection apparatus; the gripping means is included in a plunger that is slideably engaged with the fitting and directs the injection apparatus through a fitting lumen and through a catheter lumen, when the fitting is coupled to the catheter.
    Type: Application

  • Carbonaceous material with high micropore and low macropore volume and process for producing same
    Patent number: 5071820
    Abstract: A method which minimizes macropore formation while producing microporous carbon comprises a two stage process. Firstly, the carbon is heated to a temperature in the range of about 150.degree. to about 200.degree. C. in the presence of oxygen for a time in the range of about forty-five to about seventy-five minutes, then purging the reaction environment of oxygen at this temperature with nitrogen. In the second stage, the carbon is heated to a temperature in the range of about 750.degree. to about 900.degree. C. under a stream of nitrogen for a time in the range of about fifteen to forty-five minutes. The process is repeated a number of times, the number being dependent on the extent of microporosity desired.
