Abstract
Catheter assemblies including an interfacial pH controller for maintaining hydration liquid pH are provided.
Claims21
A catheter assembly comprising:
- a package defining a cavity;
- a catheter including an insertion portion with at least a portion of the catheter having a hydrophilic surface contained within the cavity of the package;
- a hydration liquid within the cavity of the package;
- and
- an interfacial pH controller comprising a salt at least partially in contact with the hydration liquid of the cavity, wherein the interfacial pH controller is incorporated into a film that is separate from the insertion portion of the catheter.
