A recently granted patent (Publication Number: US11865269B2) discloses a urinary catheter assembly designed to improve patient comfort and ease of use. The assembly includes a package with a cavity containing a urinary catheter coated with a hydrophilic material on its exterior surface. A moisture control layer, made of wax, covers a portion of the hydrophilic material, allowing for selective ingress and egress of water. This design aims to enhance the performance of the catheter during use.

Furthermore, the patent details variations in the assembly, such as the use of hexadecanol in the moisture control layer and the inclusion of amphiphilic wax. These modifications are intended to further optimize the catheter's functionality by maintaining the hydrophilic material in a hydrated state. By providing a solution for controlling moisture levels and improving water interaction with the catheter, this patented urinary catheter assembly offers potential benefits for patients requiring such medical devices, enhancing their overall experience and comfort during catheterization procedures.
