Patent application number | Description | Published |
20110076386 | Stent Fixture and Method for Reducing Coating Defects - A stent fixture for supporting a stent during formation of a coating is provided. | 03-31-2011 |
20110307050 | Laser System And Processing Conditions For Manufacturing Bioabsorbable Stents - 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. | 12-15-2011 |
20120029616 | Stent Support Devices - Various embodiments of methods and devices for coating stents are described herein. | 02-02-2012 |
20120291703 | STENT COATING APPARATUS - An apparatus for coating a stent comprises a coating solution reservoir, a stent support for carrying a stent adjacent the reservoir, transducers for generating waves through the coating solution, and a controller that controls timing at which the transducers are powered in order to eject a droplet of the coating solution. | 11-22-2012 |
20130035753 | Multiple Scaffold Design And Coating Thereof - 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. | 02-07-2013 |
20130071549 | Dryers For Removing Solvent From A Drug-Eluting Coating Applied To Medical Devices - 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 drying chamber for the stent or scaffold to reside while a heated gas is passed over the stent/scaffold. The drying chamber improves efficiency in drying, predictability or drug release rate, uniformity of coating material properties lengthwise over the stent/scaffold and provides a platform that can effectively support stents that are over 40 mm in length. | 03-21-2013 |
20140004250 | Methods of treatment of polymeric coatings for control of agent release rates | 01-02-2014 |
20140154400 | METHOD OF DRYING BIOABSORBABLE COATING OVER STENTS - 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. | 06-05-2014 |
20140155985 | LASER SYSTEM AND PROCESSING CONDITIONS FOR MANUFACTURING BIOABSORBABLE STENTS - 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.
