Abstract
The packaging for a catheter comprises a flat air tight support member and a cover member formed of an air tight and flexible sheet adhered by its periphery on the support member. A vacuum is exerted between the support member and the cover member by connection of a duct to a vacuum pump, and the duct is then sealed. The cover member thus takes the relief of the shapes of the catheter whatever they are.
