  • Publication number: 20050064210
    Abstract: The inventive coating may be employed to deliver a pharmaceutical agent to a selected body area that is involved within the insertion or application of a medical device. Such medical devices may include silicone based urinary catheters and other medical implants as well as other silicone based devices having deformable portions which could benefit from the release of a pharmaceutical agent from its surface. The coating allows the introduction of the pharmacological additive having a release rate that is within acceptable pharmacokinetic criteria. The release rate is adjusted by utilizing different salt forms of the additive and adjusting the concentration of urethane and RTV silicone. The coating incorporates additive compounds such as anti-microbial, anti-fungals and other organic compounds. Methods are also provided for the manufacture of the subject coating and for the application of the same to surfaces of medical devices.

  • 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.
