The inner core being made from flushable materials, which are preferably degradable water soluble materials such that the inner core degrades as urine or water pass through the inner conduit defined by the outer wall.
Claims20
A disposable intermittent urinary catheter, comprising:
- a flexible elongated shaft including an outer wall surrounding an inner conduit wherein the outer wall is water degradable;
- a degradable inner core extending at least partially within the conduit, the inner core defining a structural reinforcement member that reinforces the outer wall to enhance rigidity and radial incompressibility of the elongated shaft, wherein the inner core is degradable upon contact with fluid;
- and
- wherein the inner core degrades at a faster rate than the outer wall.
