Abstract

A urinary catheter and container are described. The urinary catheter may have a catheter shaft attached to a handle, and a coating disposed on an outer surface of the catheter shaft. The coating may include a hydrogel, water and/or glycerin, and a polyethylene gylcol (PEG). The PEG may have a molecular weight equal to or less than 600, for example one or more of polyethylene glycol (PEG) 300 and PEG 400. The coating may be applied in a wet state and remain wet for an extended period of time in the container, thereby obviating the need for a lubricant, such as a water sachet or gel package, to accompany the catheter in the container. The container may include a gas impermeable foil material. The container may include an adhesive tab covering a perforated section, the adhesive tab including a pull loop.
