  • Publication number: 20080226812
    Abstract: An apparatus and method for coating abluminal surface of a stent is described. The apparatus includes a stent support, a coating device, and an imaging system. The coating device includes a solution reservoir and transducer assembly. The transducer assembly includes a plurality of transducers and a controller. Each transducer is used to generate focused acoustic waves in the coating substance in the reservoir. A controller is communicated to an image system to enable the transducers to generate droplets on demand and at the predetermined ejection points on the surface of the coating substance to coat the stent. A method for coating a stent includes stent mounting, stent movement, and droplet excitation.

  • Publication number: 20080190363
    Abstract: A sleeve is positioned over a radially-expandable rod assembly and a stent is positioned over the sleeve. A mandrel is inserted into the rod assembly to thereby press the sleeve against the inner surface of the stent and expand the stent. A coating (such as a solvent, a polymer and/or a therapeutic substance) is then applied to the outer (abluminal) surfaces of the stent, by spraying, for example. The sleeve advantageously prevents the coating material from being applied to inner (luminal) surfaces of the stent and also allows the coating material to be efficiently applied to the abluminal surfaces.

  • Publication number: 20080177375
    Abstract: A stent with at least one severable supporting device and methods of coating using the same are disclosed. The severable supporting device can be an end tube or a tab attached to some portion of the stent by at least one “gate” or attachment. The end tube or tab may be part of the design of the stent when it is originally manufactured, or it may be attached to the stent in a secondary process by a biocompatible glue or solder. The end tube or tab can be used to support a stent during a coating process eliminating the need for a mandrel which would otherwise contact the stent during the coating process.

  • Publication number: 20080131585
    Abstract: A nozzle for use in a coating apparatus for the application of a coating substance to a stent is provided. Method for coating a stent can include discharging a coating composition out from a needle of a nozzle assembly, and atomizing the coating composition as the coating composition is discharged. The needle can be positioned in a chamber of the nozzle assembly, and gas can be introduced into the chamber for atomizing the coating composition.

  • Publication number: 20080124372
    Abstract: The present disclosure teaches methods of controlling the release rate of agents from a polymeric matrix that include designing and creating a predetermined initial morphology (IM) profile in a polymeric matrix. The teachings indicate, inter alia, that control over the release rate of agents can provide for an improved control over the administration of agents as well as have an effect upon the mechanical integrity and absorption rate of the polymeric matrix.
