A catheter assembly includes a catheter having on at least part of its surface a hydrophilic surface layer a wetting fluid pouch including first and second layers of flexible material joined by a seal to form a sealed closure accommodating the wetting fluid a receptacle forming a cavity for accommodation of the catheter and the wetting fluid pouch. The wetting fluid pouch is openable by compression of the wetting fluid pouch, thereby enabling the wetting fluid to be discharged into the receptacle. At least one of the first and second layers of the wetting fluid pouch extends beyond the seal of the sealed closure to form an attachment area outside the sealed closure, the wetting fluid pouch is attached to an inner surface of the receptacle, and the attachment being provided solely between the receptacle and the attachment area.
