    Abstract: Methods for forming a “coating gradient” on medical devices, such as a balloon catheter or guidewire are disclosed. The balloon portion of the catheter has a protective covering initially placed over it to prevent the balloon from receiving a first hydrophilic coating. After a first hydrophilic coating is applied, the protective covering is removed. A second hydrophilic coating could be applied to the catheter. A guidewire having less lubricity at the distal end portion also can be created. A first hydrophilic coating is applied to the elongated shaft and distal shaft section of the guidewire. After the first hydrophilic coating cures, the first hydrophilic coating is removed from a portion of the distal shaft section of the guidewire. A second hydrophillic coating can then be applied to the elongated shaft and distal shaft section of the guidewire. The second hydrophilic coating can be allowed to cure.

    Abstract: Balloon catheter includes an outer shaft including a hypotube and a monolithic multilayer distal outer member and having an inflation lumen defined therethrough, a balloon in fluid communication with the inflation lumen, and an inner tubular member having a guidewire lumen defined therethrough. The monolithic multilayer distal outer member has a proximal end portion and a distal end portion. The monolithic multilayer distal outer member has an inner layer comprising a first polymer having a tensile strength greater than about 8,000 psi and an outer layer comprising a second polymer having a flexural modulus of less than about 130,000 psi at room temperature. A proximal end of the monolithic multilayer distal outer member is coupled to the hypotube. The monolithic multilayer distal outer member is necked to a reduced diameter along at least a portion of a length thereof. The balloon has a proximal balloon shaft coupled to a distal end of the monolithic multilayer distal outer member. The inner tubular member extends distally from a proximal port in the proximal end portion of the monolithic multilayer distal outer member through at least a portion of the balloon.
