Abstract: Composite fiber reinforced balloons for medical devices prepared by applying a web of fibers to the exterior of a preformed underlying balloon and encasing the web with a matrix material to form a composite balloon. The fiber web is applied to at least the cone portion of the underlying balloon form. Either the cone portion of the underlying balloon form, or the web fibers applied to said cone portion, or both, have a friction-enhancing material coated thereon.

Abstract: A medical device that may be implanted in a patient's body is disclosed. An illustrative medical device has an elongated structure that includes a material loaded with a radiopaque material. The radiopaque material includes radiopaque particles having multiple sets of radiopaque particles. The multiple sets of radiopaque particles may include a first set of radiopaque particles having particles with particle sizes in a first particle size range and a second set of radiopaque particles having particles with particle sizes in a second particle size range. The second set of radiopaque particles may have particles configured to fit within interstitial spaces between particles of the first set of radiopaque particles.

Abstract: Nanoparticles can be embedded into a medical device by accelerating them to a speed of between 100 m/s and 1,000 m/s and embedding the particles into a polymer surface of a medical device or a precursor thereof. In some cases, the nanoparticles can be embedded until the nanoparticles accumulate in sufficient number to adhere together to form a coating over the polymer surface. The nanoparticles can provide a conductive pathway, an abrasion resistant surface, a pro-healing surface, and/or an anti-bacterial surface.
