Abstract: In an example, a scoring device is configured for retention of a catheter shaft. The scoring device incudes a proximal portion and a distal portion. A retention sleeve extends between the proximal and distal portions. The retention sleeve has a catheter socket configured to selectively receive and mechanically engage the catheter shaft. The scoring device includes a scoring tool coupled with the retention sleeve, for instance proximate to the distal portion. The scoring tool includes a balloon socket configured to selectively receive a balloon of the catheter shaft. The scoring tool includes one or more scoring elements extending around the balloon socket, the one or more scoring elements configured to provide localized scoring to vasculature.

Abstract: Embodiments of the disclosure include coatings comprising an oligomerized polyphenol layer. The oligomerized polyphenol layer can be used as an intermediate coated layer on a medical device that hydrogen bonds to a synthetic or natural polymer, which in turn can be used as a top coat or further associated with another coated layer. The multilayered coatings can provide properties such as hemocompatibility or lubricity. In other embodiments, the oligomerized polyphenol layer is used on a medical device as a hemostatic layer configured to contact blood and promote coagulation. The oligomerized polyphenol layer can also be used on the inner surface (e.g., inner diameter) of a medical device to prevent bacterial adherence. The oligomerized polyphenol layer can also be used on the surface of a in vitro diagnostic article, or a cell culture device to, promote adsorption of a biological molecule.

Abstract: 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.
