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.02-13-2014
20140039604CRUSH RECOVERABLE POLYMER SCAFFOLDS - A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold, after being deployed by the balloon, provides a crush recovery of about 90% after the diameter of the scaffold has been pinched or crushed by 50%. The scaffold has a pattern including an asymmetric closed cell connecting links connecting the closed cells.02-06-2014
20140039603BIOABSORBABLE SCAFFOLDS MADE FROM COMPOSITES - Bioabsorbable scaffolds made at least in part of a poly(L-lactide)-based composite are disclosed. The composite includes poly(4-hydroxybutyrate) or poly(L-lactide)-b-polycaprolactone block copolymer, which increases the fracture toughness or fracture resistance of the scaffold. The composite can further include bioceramic particles, L-lactide monomer, or both dispersed throughout the composite. The bioceramic particles improve the radial strength and stiffness of the scaffold. The L-lactide monomer is used to control the absorption rate of the scaffold.02-06-2014

20140037832Coating Layers For Medical Devices And Method Of Making The Same - Methods are disclosed for controlling the morphology and the release-rate of active agent from coating layers for medical devices comprising a polymer matrix and one or more active agents. The methods comprise fixing the morphology or phase distribution of the active agent prior to removing solvent from the coating composition. The coating layers can be used for controlled the delivery of an active agent or a combination of active agents.02-06-2014
20140037831Coating Layers For Medical Devices And Method Of Making The Same - Methods are disclosed for controlling the morphology and the release-rate of active agent from coating layers for medical devices comprising a polymer matrix and one or more active agents. The methods comprise fixing the morphology or phase distribution of the active agent prior to removing solvent from the coating composition. The coating layers can be used for controlled the delivery of an active agent or a combination of active agents.02-06-2014
20140033506METHODS FOR CRIMPING A POLYMERIC STENT ONTO A DELIVERY BALLOON - A medical device—includes a polymer stent crimped to a catheter having an expansion balloon. The stent is crimped to the balloon by a process that includes heating the stent to a temperature below the polymer's glass transition temperature to improve stent retention without adversely affecting the mechanical characteristics of the stent when later deployed to support a body lumen.02-06-2014
20140033504Method of Making Implantable Prosthesis with Depot Retention Feature - A prosthesis for intraluminal drug delivery can comprise a plurality of interconnected struts that form a tubular scaffold structure. The struts include through-holes with an inner surface configured to retain a bioabsorbable depot. The bioabsorbable depot includes a drug-polymer composition that hydrolytically degrades upon implantation. The inner surface of the through-hole can be an entirely smooth and continuous area that is concave or convex, with no geometric discontinuities. The inner surface of the through-hole can include any number of constricted and distended regions to form grooves of a size and shape carefully selected to engage a corresponding geometric feature of the bioabsorbable depot.02-06-2014
20140031921CRUSH RECOVERABLE POLYMER SCAFFOLDS - A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon.
