  • Patent number: 7955637
    Abstract: An electrosurgical device including a reinforcing underlayment having a non-stick, anti-microbial coating. In one embodiment, the coating includes a non-stick material having anti-microbial particles interspersed in the non-stick material. This coating is applied to the surfaces of the electrode to minimize the build-up of charred tissue on the surfaces of the electrode. Also, the coating tends to kill harmful organisms residing on the surfaces of the electrode. In another embodiment, a primer coating is initially applied to the surfaces of the electrode. A plurality of anti-microbial particles are then applied to the primer coating layer and engage and are embedded in the primer coating layer. A top coat including a non-stick material is applied to the anti-microbial particle layer. In either embodiment, the coating layers applied to the surfaces of the electrode are cured to harden and adhere the layers to the electrode.

  • Patent number: 7951413
    Abstract: A balloon for a catheter and a method of making the balloon, having a layer of a porous polymeric material with a modified outer surface and a lubricious coating bonded to the modified outer surface. In one embodiment, the modified outer surface is formed by a polymer impregnated in the porous polymeric material, and the subsequently applied lubricious coating bonds to the impregnating polymer. In another embodiment, the modified outer surface is formed by a functionality deposited on the porous polymeric material which bonds to the subsequently applied lubricious coating. The modified outer surface provides an improved strong bond between the lubricious coating and the balloon, for improved catheter performance.

  • Patent number: 7951412
    Abstract: A method is provided for depositing a hard wear resistant surface onto a porous or non-porous base material of a medical implant. The wear resistant surface of the medical implant device may be formed by a Laser Based Metal Deposition (LBMD) method such as Laser Engineered Net Shaping (LENS). The wear resistant surface may include a blend of multiple different biocompatible materials. Further, functionally graded layers of biocompatible materials may be used to form the wear resistant surface. Usage of a porous material for the base may promote bone ingrowth to allow the implant to fuse strongly with the bone of a host patient. The hard wear resistant surface provides device longevity, particularly when applied to bearing surfaces such as artificial joint bearing surfaces or a dental implant bearing surfaces. An antimicrobial material such as silver may be deposited in combination with a metal to form an antimicrobial surface deposit.

  • Patent number: 7935379
    Abstract: The present invention relates generally to coated medical devices, preferably a stent, that has a drug-eluting surface completely or partially coated with a coating that is imprinted with an impression. In particular, the invention is directed to a coated medical device having a coating that comprises biologically active materials, polymers, or a combination thereof. The coating is imprinted with an impression by printing, molding, lithography, or embossing techniques. Preferably, the patterning imprinted on the coating is capable of releasing biologically active materials in different amounts, at different rates, and/or at different time periods. The invention also relates to methods of making and methods of using the coated medical device.

  • Patent number: 7935185
    Abstract: A clean gas circulates to pass through a loading area provided below a vertical heat treatment furnace. The clean gas unidirectionally flows through the loading area. After completion of wafer processing, a wafer boat lowers from the heat treatment furnace to the loading area, where the wafers are removed from the wafer boat. Subsequently, a clean gas jetting nozzle arranged in the loading area jets a clean gas toward the emptied wafer boat. Fragment of thin film which may readily peel off are blown away from the wafer boat, and are discharged out of the loading area together with the unidirectional flow. Thus, it is possible to avoid wafer contamination due to the unexpected peel-off of thin film fragments from the wafer boat.

  • Patent number: 7931932
    Abstract: A medical device with a therapeutic agent-releasing polymer coating. The medical device is provided by a method that comprises: (a) attaching at least one reactive species to a medical device surface, which reactive species leads to chain growth polymerization in the presence of monomer; (b) contacting the reactive species with at least one monomer species, thereby forming a polymer coating on the surface of the medical device; and (c) providing at least one therapeutic agent within the polymer coating. The therapeutic agent may be incorporated during formation of the polymer coating or after formation of the polymer coating. The at least one reactive species can comprise, for example, a free radical species, a carbanion species, a carbocation species, a Ziegler-Natta polymerization complex, a metallocene complex, and/or an atom transfer radical polymerization initiator.

  • Patent number: 7927650
    Abstract: The beneficial agent is applied into the holes in a medical device in a dry particulate form and is adhered in the hole in a manner that allows release of the drug in a controlled manner. The drug material would be formed into particles and placed in the holes. The solvent would be added to partially liquefy and adhere the drug into the holes. After application of the solvent, the particles are adhered together in a substantially uniform drug containing matrix. The particles may include drug alone or drug in combination with other materials including a matrix.

  • Patent number: 7914841
    Abstract: A method of forming a coated medical device is described. A coating may be applied inline to a continuous tubing formed by extrusion, prior to cutting and secondary operations. Thus, inefficient and labor-intensive steps associated with preparing individual tubes for coating may be avoided. The method may include forcing a flowable material through an exit port of an extruder, depositing a coating onto at least a portion of the continuous length of extruded tubing after the tubing is forced through the exit port, cutting the coated tubing to a desired length after depositing the coating, and performing one or more secondary operations on the coated tube at a temperature in the range of from about 15° C. to about 375° C.
