Patent Images
1. A catheter assembly, comprising:
- a catheter defining at least one lumen;
a hub including at least one hub extension dimensioned to be received within the at least one lumen of the catheter; and
a sealing member being of an expandable material which increases in volume upon exposure to moisture, wherein the at least one hub extension defines a first connector surface and the at least one lumen of the catheter is defined by a second connector surface,wherein when the at least one hub extension is received within the at least one lumen of the catheter, the first connector surface engages the second connector surface to define an interface, wherein the sealing member is positioned adjacent the interface and is configured to expand into the interface between the first connector surface and the second connector surface upon exposure to the moisture such that the expandable material fills in any gaps between the at least one hub extension and the at least one lumen at the interface.
