Abstract
An alcohol-resistant siliconized polycarbonate polyurethane can include a soft segment and a hard segment. The soft segment can include a polycarbonate polyol and a polysiloxane, which can be present in an amount less than the polycarbonate polyol. The hard segment can include an isocyanate and a chain extender. Peripherally inserted central catheter (PICC) devices can include one or more components that are at least partially formed from one or more formulations of the siliconized polycarbonate polyurethane catheter. The PICC devices can withstand alcohol locking, and can be power injectable both before and after alcohol locking events.
