摘要： Embodiments of the disclosure include lubricious coatings. In an embodiment the disclosure includes a lubricious coating for a medical device including first and second coated layers. The first coated layer is between the second coated layer and the device surface and includes a vinyl pyrrolidone polymer and a photo reactive group. The second coated layer is in direct contact with the first coated layer and is a top coating that includes an acrylic acid polymer. The second coated layer can optionally include photoreactive groups. The coating was found to have a very low number of particulates (e.g., 10 μm or greater) which is very desirable for in vivo use.

摘要： Aspects herein relate to a low-friction septum for providing a leak-resistant seal for use in a vascular access device. In an embodiment, a device for vascular access hemostasis is included having an enclosure defining a cavity and configured to at least partially receive a medical device. The device can include a first seal portion and a second seal portion, the cavity disposed between the first seal portion and the second seal portion. The device can include a barrel in structural communication with the second seal portion, the second seal portion including a septum seal. The second seal portion can define two or more discrete portions, each separated by one or more split lines. The discrete portions can include a mating surface to interface with mating surfaces of other discrete portions. The mating surface can include a surface topology including raised portions and depressions. Other embodiments are also included herein.

摘要： A catheter assembly includes an expandable and collapsible structure having an outer surface. The expandable and collapsible structure is adapted to expand between a contracted state and a dilated state. A coating is disposed on the outer surface of the expandable and collapsible structure. The coating includes a bioactive agent. A sleeve is disposed over the coating. The sleeve is adapted to expand between a compressed state and an enlarged state and to return to the compressed state. The sleeve defines a plurality of openings in the compressed state. An outer diameter of the coating is less than an outer diameter of the sleeve when the expandable and collapsible structure is in the contracted state and greater than the outer diameter of the sleeve when the expandable and collapsible structure is in the dilated state.
