    摘要: A method for electrostatic coating of medical devices such as stents and balloons is described. The method includes applying a composition to a polymeric component of a medical device which has little or no conductivity. The polymeric component could be a material from which the body or a strut of the stent is made or could be a polymeric coating pre-applied on the stent. The polymeric component could be the balloon wall. A charge can then be applied to the polymeric component or the polymeric component can be grounded. Charged particles of drugs, polymers, biobeneficial agents, or any combination of these can then be electrostatically deposited on the medical device or the coating on the medical device. One example of the composition is iodine, iodine, iodide, iodate, a complex or salt thereof which can also impart imaging capabilities to the medical device.

    摘要: A system and method for coating an expandable member of a medical device comprises providing a dispenser in fluid communication with a fluid source with the dispenser having at least one outlet to dispense fluid of the fluid source therefrom. The outlet(s) of the dispenser is positioned proximate a surface of an expandable member, with relative movement between the outlet(s) and the surface of the expandable member established along a coating path, and fluid is dispensed from the dispenser to form a substantially continuous bead of fluid between the at least one outlet and the surface of the expandable member along the coating path, and simultaneously drying the fluid while dispensing the fluid from the dispenser to control flow of fluid on the surface of the expandable member. The fluid source can include a variety of therapeutic agents.

    摘要: A systems and method for reducing coating defects on a stent may involve a support apparatus comprising wire cage for carrying a stent. The support apparatus may have no structure that extends inside the stent. A support apparatus may include a plurality of wires that pass through the stent but do not pass through the midplane of the stent. A support apparatus may contact only the proximal ends of the stent. The method may involve keeping the stent in motion during a spray coating process to prevent the stent from having a point remain in continuous contact with a support apparatus.

    摘要: A stent for delivery of a therapeutic agent is disclosed. The stent includes a polymer coating for reducing the rate of release of the therapeutic agent. The polymer has a crystalline structure wherein the polymer is capable of significantly maintaining the crystalline lattice structure while the therapeutic agent is released from the stent such that the aqueous environment to which the stent is exposed subsequent to the implantation of the stent does not significantly convert the crystalline lattice structure of the polymer to an amorphous structure.
