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.
