  • Method to stabilize TDMAC heparin coating
    Patent number: 5441759
    Abstract: A medical device is coated with a solution of TDMAC heparin and then allowed to air dry. Thereafter, the coated medical device is exposed to gamma ray radiation. The gamma radiation strengthens the bond of the TDMAC to the material of the medical device. In a variation of this method, TDMAC heparin coated and gamma ray irradiated medical device is heated for an extended period of time. This heating has been found to further strengthen the bond of the TDMAC heparin to the medical device.
