摘要:
The invention relates to a Foley-type catheter constructed to prevent the retention balloon from cuffing, and methods of making the same. In an embodiment, the invention relates to a catheter including an additional sheath layer over the outside surface of the catheter and methods of making and using the same. The catheter includes a central layer that defines a first lumen and a second lumen. The catheter further includes a balloon layer surrounding the central layer and a balloon cavity disposed between the exterior surface of the central layer and the balloon layer. A sheath layer surrounds the balloon layer and extends over the balloon cavity. In an embodiment, the invention relates to a catheter with a retention balloon including ribs and methods of making and using the same. The catheter includes a central layer defining a first lumen and a second lumen and a sheath layer surrounding the central layer. The catheter further includes a balloon cavity. The portion of the sheath layer defining the balloon cavity has a plurality of ribs parallel to the length of the catheter. The ribs include a material that resists stretching more than the material of the sheath layer.
