  • Method of preparing a biological glue able to coagulate simply by addition of calcium ions
    Patent number: 5985315
    Abstract: By placing a blood plasma in contact with a blood coagulation contact phase activator, before or during preparation of a fibrinogen-based biological glue, a preactivated biological glue is obtained which does not coagulate spontaneously but which is capable of coagulating in less than 5 minutes simply by the addition of calcium ions, without the addition of thrombin. The process has application to the field of surgery.
    Type: Grant
    Filed: December 30, 1997
    Date of Patent: November 16, 1999

  • Device for producing a supernatant of activated thrombocytes, method for implementing the device and supernatant obtained
    Patent number: 5618663
    Abstract: A method for preparing platelet factors features a liquid that contains a suspension of thrombocytes being passed over a filter capable of retaining the thrombocytes. Thrombocytes are activated by an activating solution that is administered to the thrombocytes retained on the filter. A filtrate containing platelet factors in solution is separated by filtration while the thrombocytes are retained on the filter.
