A catheter product (200) comprising an extendable urinary catheter (20) including a proximal end section (22) and a distal end section (24) that are concentric and slide relative to one another, and a package (202) containing the extendable catheter (20) in a collapsed configuration. A retaining member (218) is associated with a proximal end portion (226) of an elongated body (204) of the package (202), the retaining member (218) holding the proximal end section (22) of the extendable urinary catheter (20) as the proximal and distal end sections (22,24) of the extendable urinary catheter (20) are pulled apart to slide relative to one another, thereby moving the extendable urinary catheter (20) into an extended configuration.
