Abstract: The catheter comprises a catheter tube formed of two superposed tubular layers of materials which differ from one another. A tubular mediator layer is arranged between the layers to provide an adhesive anchorage for the layers.

Abstract: An interventional catheter for angioplasty and the like, comprising a catheter tube including an outer tubular member, an inner tubular member disposed within the lumen of the outer tubular member, and a balloon attached to the distal end of the outer tubular member and the distal end of the inner tubular member. The outer tubular member includes a first portion having a first stiffness and a second portion having a second stiffness less than the first stiffness. The inner tubular member has an inner surface having a first coefficient of friction and an outer surface having a second coefficient of friction greater than the first coefficient of friction.

Abstract: An interventional catheter for angioplasty and the like, comprising a catheter tube formed of two superposed layers of materials different from one another. The inner layer is comprised of a low friction nonkinkable material to avoid risk of clogging of a guide wire in the longitudinal lumen. The outer layer is comprised of a material with higher friction coefficient than the material forming the inner layer. The balloon is welded at its distal end to the outer layer of the catheter tube. The proximal end of the balloon is welded to a tube surrounding the catheter tube.

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.

Abstract: A packaging comprises a sealed peel-apart flexible pouch in which the preshaped stem of a medical appliance is maintained by elastic pressure of the walls of a sheath open at its ends formed by a wall having two parallel lateral edges forming slides in which are engaged the lateral edges of two spaced apart portions of a second wall. The two walls are flat and deformable by their own elasticity. A retaining window is provided in one of the walls for a handling and connecting hub connected to the stem of the medical appliance to extend therethrough.
