摘要:
A catheter assembly and method is disclosed which comprises a catheter having a coating on at least a part of its length intended to produce a low-friction surface on the catheter when treated with an activating substance in the form of a vapor. The catheter assembly also includes a catheter package forming an interior space divided by a gas permeable, liquid impermeable barrier into a first cavity and a second cavity. The first cavity of the catheter package accommodates the catheter therein and the second cavity accommodates at least a quantity of liquid in its liquid phase therein. The liquid in the second cavity can change phase into a vapor capable of passing from the second cavity, through the barrier, and into the first cavity where the vapor can activate the coating. As a result, the vapor produced when the liquid changes phase causes the coating on the catheter to be activated to thereby produce the low-friction surface on the catheter so it is ready-to-use when it reaches the end user.
