摘要: Medical articles formed from a polyurethane-based resin including a modifying oligomer provide enhanced properties. A modifying oligomer incorporated into a backbone, as a side chain, or both of the polyurethane-based resin formed by a diisocyanate, a polyglycol, and a diol chain extender has at least one, preferably two, alcohol moieties (C—OH) and a functional moiety. Exemplary modifying oligomers are: a diol-containing perfluoropolyether incorporated into the backbone, a monofunctional polysiloxane (e.g., monodialcohol-terminated polydimethylsiloxane) incorporated as the side chain, and combinations thereof. Medical articles herein are self-lubricating and/or anti-fouling.

摘要: In some examples, a device includes a catheter insert elongated body defining a body lumen, the catheter insert elongated body being configured to be at least partially inserted to a catheter lumen defined by a catheter without covering a first fluid opening of the catheter and to form a fluidically tight coupling with the catheter, and one or more sensors positioned on the elongated body. At least one of the one or more sensors are configured to sense a substance of interest. The catheter insert elongated body includes a material that is a substantially non-permeable to the substance of interest.
