Abstract:
1. A catheter assembly comprising: a catheter having on at least part of its surface a hydrophilic surface layer intended to produce a low-friction surface character of the catheter by treatment with a wetting fluid prior to use of the catheter; a catheter receptacle forming a cavity for accommodation of at least part of the catheter and a compartment accommodating said wetting fluid, wherein said compartment is monolithic to the receptacle, but being separated from said cavity; and a rupturable sealed closure separating the cavity and the compartment, wherein said rupturable sealed closure is a welded joint arranged in a non-linear arrangement so that the welded joint is arranged with at least one knee directed toward the wetting fluid compartment, and wherein a peak portion of said at least one knee provides a corresponding at least one point of maximized weakness, in order for an induced rupture to occur in a predetermined position, thereby enabling fluid communication between the compartment and the cavity housing the catheter.
