Abstract: The present invention provides improved medical devices for use in surgical procedures and methods for manufacturing improved medical devices. In some embodiments, the improved medical devices can include improved surgical needles that are capable of being repeatedly passed through tissue using minimal force. More particularly, the improved surgical needles can be manufactured with two or more different coatings that provide the surgical needles with both durability and lubricity for ease of repeated and successive passes through tissue. Improved methods for manufacturing the surgical needles and for providing and applying coatings to the surgical needles are also provided.

Abstract: A method of forming a lubricating film on a surface, comprising applying to a surface a multiphasic composition comprising at least one (per)fluoropolyether (PFPE) lubricant, water and from 0.1 to 3% by weight of water of at least one thickening agent, said multiphasic composition having a viscosity, when measured at 21° C. at a shear rate of 1 sec?1 of at least 10 Pa×sec so as to form a layer, and drying said layer to form a lubricating film. The Applicant has found that by the use of the multiphasic composition as above detailed it is advantageously possible to convey to surface to be lubricated the PFPE lubricant by using application techniques (doctor blade, metering rod, . . . ) as those suitable for solid-like greases, while the actual conveyed lubricant behaves in lubrication as an oil, avoiding the use of fluorinated solvents.

Abstract: The present disclosure provides a device for preventing the fouling of a liquid dispensing nozzle. The end of the dispensing nozzle is placed in a hollow interior of a band carrying the same solvents that are dispensed by the nozzle. The solvent on the band evaporates into a gap between the ring and dispensing nozzle, thus providing a vapor sheath or environment that helps to prevent the fouling of the dispensing nozzle.

Abstract: A method of method of coating powdered medical agent onto a carrier particle for use in a dry powder inhaler may include applying ultrasonic energy to agglomerated powdered medical agent to deaggregate and aerosolize particles of the medical agent into particles having a desired average particle size, and coating at least one carrier particle with a desired amount of the deaggregated and aerosolized particles of the medical agent.
Abstract: A method of loading a composition into a structural element of a stent, where the structural element is defined by a lumen and at least one opening to access the lumen. The composition may comprise a therapeutic agent, and wherein at a temperature of 30° C. and at one atmosphere, the composition may be in a solid state or semi-solid state.
Abstract: A method of coating a stent comprises contacting a first axial portion of a stent with a support element, such that a second axial portion does not contact the support element or any other support element, applying a coating material to the second axial portion, and inhibiting or preventing application of the coating material on the first axial portion. A shuttle sheath can be used to push the stent off the support element.
Abstract: Endoprostheses and methods of making endoprostheses are disclosed. For example, endoprostheses are described that include an endoprosthesis body, a biodegradable metallic tie layer, and a polymer coating about the endoprosthesis body. The biodegradable tie layer and the polymer coating can have a high peel strength from the body.

Abstract: A method for electrostatic coating of medical devices such as stents and balloons is described. The method includes applying a composition to a polymeric component of a medical device which has little or no conductivity. The polymeric component could be a material from which the body or a strut of the stent is made or could be a polymeric coating pre-applied on the stent. The polymeric component could be the balloon wall. A charge can then be applied to the polymeric component or the polymeric component can be grounded. Charged particles of drugs, polymers, biobeneficial agents, or any combination of these can then be electrostatically deposited on the medical device or the coating on the medical device. One example of the composition is iodine, iodine, iodide, iodate, a complex or salt thereof which can also impart imaging capabilities to the medical device.
