1. A urinary catheter, comprising:
a handle;
a catheter shaft attached to the handle;
a base coating over the catheter shaft; and
an outer coating over the base coating, each coating of the base coating and the outer coating including a combination of components selected from a hydrogel, polyacrylic acid (“PAA”), glycerin, water, and polyethylene glycol (“PEG”) such that the base coating and the outer coating are in a wet state sufficient for insertion of the catheter shaft into a urethra without applying an additional moisture source or lubricant to the base coating or the outer coating.
