Abstract: Embodiments herein include an insertion tool for inserting a medical device into another medical device, such as a hemostasis sealing valve, and related methods. In an embodiment, an insertion tool includes a guide sheath and a protection tube. The guide sheath can include a flared proximal end. The guide sheath can further include a central lumen. The guide sheath can further include a locking notch disposed on the inner surface between the proximal end and the distal end. The protection tube can include a flared proximal end. A portion of the protection tube can be situated within the central lumen of the guide sheath. The flared proximal end of the protection tube can be sized to fit within the locking notch and can have an outer diameter larger than portions of the inner surface immediately adjacent to the locking notch. Other embodiments are also included herein.

Abstract: The invention is directed to latent reactive and polymerizable derivatives of fluorescent stilbene-based compounds. The compounds can be used to provide articles with a fluorescence property, such as medical devices (e.g., catheters). The fluorescent compounds can be used in association with polymers, or can be incorporated into polymers, and the polymers used in a coating composition on the article surface. The compounds allow for visual or machine inspection of coating properties such as uniformity of coverage.
