The present invention involves laser machining polymer substrates to form a stent with laser parameters that minimize damage to the substrate in a surface region adjacent to the machined edge surface. The wavelength and pulse width are selected for this unique application and they can be controlled to minimize the surface modifications (such as voids, cracks which are induced by the laser-material interaction) which contribute to the variation in mechanical properties with distance from the edge surface, bulk mechanical properties, or a combination thereof.

Laser system and processing conditions for manufacturing bioabsorbable stents

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.

Method for forming a coating on a stent

A multiple stent structure including a plurality of stent bodies arranged end to end in which adjacent stent bodies of the structure are connected by a severable connecting portion disposed between the adjacent stent bodies is disclosed. A method of coating a plurality of stents including depositing a coating on the multiple stent structure and severing the severable connecting portions to disconnect the plurality of stent bodies is disclosed.

Multiple scaffold design and coating thereof

Various embodiments of methods and devices for drying coated stents in an oven are described herein.

Device for drying coated stents

A coating device for coating a medical device with a drug-eluting material uses an in-process drying station between coats to improve a drug release profile. The drying station includes a dryer having a telescoping plenum which provides a shield and drying region for the stent or scaffold to reside while a heated gas is passed over the stent/scaffold. The shield and drying region improve efficiency in drying, predictability or drug release rate, uniformity of coating material properties lengthwise over the stent/scaffold and provide a platform that can effectively support stents that are over 40 mm in length.

Dryers for removing solvent from a drug-eluting coating applied to medical devices

Various embodiments of methods and devices for coating stents are described herein.

The present disclosure teaches methods of controlling the release rate of agents from a polymeric matrix. The methods relate to the application of pressure, and optionally, in combination with heat, to a polymeric coating.

Methods of treatment of polymeric coatings for control of agent release rates

Methods and devices for coating stents

A coating device for coating a medical device with a drug-eluting material uses an in-process drying station between coats to improve a drug release profile. The drying station includes a heat nozzle configured for applying a uniform drying gas.

Removing a solvent from a drug-eluting coating

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.
