    Abstract: The present invention relates to a method for making a silicon balloon catheter in which a first tube having its outer diameter slightly smaller than that of a desired catheter is formed by an extruding method, mold lubricant is coated at a portion of a balloon injection opening, a thin film type second tube is formed at the coated outer surface of the first tube by a second extruding, and then the catheter is vulcanized and cut. As a result, when liquid is injected to an expansion tube, the second tube is separated from the first tube, thereby performing a function as a balloon. The method for making a balloon catheter using silicon rubber includes the steps of: forming a first tube by extruding firstly, the tube having its outer diameter slightly smaller than that of a desired catheter, then vulcanizing and cutting the first tube; punching two balloon injection openings having small diameter at a portion for expanding into balloon in the first tube after inserting a support rod into a discharge tube path; coating mold lubricant at a portion of the balloon injection opening; connecting the first tubes coated the mold lubricant by using a connection unit after removing the support rod, and thereafter forming a second tube at the coated outside surface of the first tube by extruding secondly, performing a vulcanizing process and cutting again; forming a tip at the tip portion of the first and second tubes; and punching a urine discharge opening at the first tube.

    Abstract: A peelable protective sheath and related assemblies/systems and methods are disclosed. The protective sheath may be used on a balloon catheter to protect the balloon and any coating thereon. The protective sheath may be peelable to make removal of the protective sheath easier. The peelable protective sheath may be inserted into a hemostatic valve and introducer while still disposed over the balloon of a balloon catheter to protect the balloon and any bioactive coating thereon from damage during insertion. The peelable protective sheath may be peeled from a proximal end to initiate removal. Alternatively, the peelable protective sheath may be peeled from a distal end of the peelable protective sheath as the balloon catheter is inserted through a hemostatic valve and introducer.
