| 20120135133 | METHOD FOR COATING METAL IMPLANTS WITH THERAPEUTIC MIXTURES - Disclosed herein are methods of treating an article surface. The method comprises delivering a polymer and drug to a medical implant having a porous surface and using at least one particle stream from at least one fluid jet to subsequently remove the polymer from the outer surface of the metal substrate, thereby retaining the therapeutic agent and polymer within the pores of the implant. | 05-31-2012 |
| 20120114830 | METHOD OF DOPING SURFACES - Disclosed herein are methods of treating an article surface. The method comprises removing a metal oxide surface from the metal substrate to expose a metal surface; and delivering particles comprising a dopant from at least one fluid jet to the metal surface to impregnate the surface of the article with the dopant. The method also comprises delivering substantially simultaneously a first set of particles comprising a dopant and a second set of particles comprising an abrasive from at least one fluid jet to a surface of an article to impregnate the surface of the article with the dopant. | 05-10-2012 |
| 20110104991 | NOZZLE CONFIGURATIONS FOR ABRASIVE BLASTING - Disclosed herein are nozzle configurations for an abrasive blasting system. The system can comprise multiple hoppers for feeding separate powders streams to a fluid jet. The separate powder streams can be mixed in a frustoconical or conical mixer prior to delivery to the substrate surface. Also disclosed are methods of texturizing the substrate surface by moving the substrate or nozzle(s) during the delivery of dopant(s). Methods for achieving a uniform distribution of dopant are also described. Also disclosed herein are coaxial nozzle configurations having an outer focusing stream to converge and/or mix with an inner particle stream. | 05-05-2011 |
| 20110081399 | SURFACE MODIFICATION OF NITINOL - Disclosed herein are methods of modifying a nitinol surface by using abrasive blasting techniques. The surface modification can be performed by abrasively blasting the surface and delivering at least one dopant from one or more fluid jets to cause the at least one dopant to impregnate and/or coat the nitinol surface. The nitinol surface can form a portion or all of a medical device, such as an implantable medical device, e.g., a stent. | 04-07-2011 |
| 20100173569 | BLASTING DEVICE AND CONTAINMENT - Disclosed herein is a containment system for a blasting device to prevent release of resulting particulate material into the environment. The system comprises a blasting device having at least one fluid jet nozzle for delivering a stream of particles under pressure toward a substrate positioned on a supporting platform. The containment is a plastic, flexible container having openings penetrated by the at least one fluid jet nozzle and supporting platform. The openings are sealably attached to the blasting device to isolate the interior of the container and the device from the outer environment. | 07-08-2010 |
| 20080274671 | METHOD OF DOPING SURFACES - Disclosed herein are methods of treating an article surface. The method comprises removing a metal oxide surface from the metal substrate to expose a metal surface; and delivering particles comprising a dopant from at least one fluid jet to the metal surface to impregnate the surface of the article with the dopant. The method also comprises delivering substantially simultaneously a first set of particles comprising a dopant and a second set of particles comprising an abrasive from at least one fluid jet to a surface of an article to impregnate the surface of the article with the dopant. | 11-06-2008 |
