  • Method for forming a coating on a stent
    Patent number: 10279372
    Abstract: A method for forming a coating on a stent involves spraying or drying a coating on the stent while the stent is supported on a mandrel assembly, during which part of the stent is made to go out of contact with the mandrel assembly.

  • Tapered scaffolds
    Patent number: 10064745
    Abstract: A stent or scaffold has a tapered end or ends. The scaffold is made using an additive manufacturing technique such as stereolithography (SLA). The scaffold may take the shape of a frustum, or a scaffold having one or both of its ends flared. The scaffold has varying mechanical properties over its length, such as a varying ring stiffness, porosity or elasticity modulus. In one embodiment the strut and link widths change linearly from the distal to proximal ends.

  • Method of drying bioabsorbable coating over stents
    Patent number: 9375876
    Abstract: Various embodiments of methods for coating stents are described herein. Applying a composition including polymer component and solvent to a stent substrate followed by exposing the polymer component to a temperature equal to or greater than a Tg of the polymer component is disclosed. Repeating the applying and exposing one or more times to form a coating with the result that the solvent content of the coating after the final exposing step is at a level suitable for a finished stent is further disclosed.

  • APPARATUS FOR COATING A STENT
    Publication number: 20150101529
    Abstract: An apparatus for coating a stent can comprises a support element, spray nozzle, and a shuttle sheath. A method of coating a stent comprises contacting a first axial portion of a stent with the support element, such that a second axial portion does not contact the support element or any other support element, applying a coating material to the second axial portion, and inhibiting or preventing application of the coating material on the first axial portion. The shuttle sheath can be used to push the stent off the support element.
