    Abstract: A catheter having an elongated shaft which has a multilayered distal tip with a first layer formed of a polyimide first material and a second layer formed of a polymeric second material. In one embodiment the multilayered distal tip is a separate member, distal to the distal end of a proximal portion of the shaft. In another embodiment, the shaft has an outer tubular member, and a multilayered inner tubular member with a distal end which forms the multilayered distal tip of the shaft. In a presently preferred embodiment, the polyimide material is a thermoset polyimide. In one embodiment, the polymeric second material is a polyamide material.

    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 could have a protective covering initially placed over it to prevent the balloon from receiving a first hydrophilic coating. After a first hydrophilic coating is applied to the catheter, the protective covering can be removed exposing the uncoated surface of the balloon. Next, after the protective covering has been removed, a second hydrophilic coating could be applied to the catheter. A guidewire having less lubricity at the distal end portion of the guidewire than the shaft portion which extends proximally away from the distal end section can be created. The method includes the application of a first hydrophilic coating on the elongated shaft and distal shaft section of the guidewire. This first hydrophilic coating is then allowed to cure. Next, the first hydrophilic coating is removed from a portion of the distal shaft section of the guidewire. After the first coating has been removed, a second hydrophillic coating can be applied to the elongated shaft and distal shaft section of the guidewire. The second hydrophilic coating can be allowed to cure.

    Abstract translation: 公开了在诸如气囊导管或导丝的医疗装置上形成“涂层梯度”的方法。 导管的气囊部分可以具有最初放置在其上的保护性覆盖物，以防止气囊接收第一亲水性涂层。 在对导管施加第一亲水涂层之后，可以去除保护性覆盖物，暴露气球的未涂覆表面。 接下来，在保护覆盖物被去除之后，可以将第二亲水涂层施加到导管。 可以产生在导丝的远端部处具有比远离远端部分向远侧延伸的轴部更小的润滑性的导丝。 该方法包括在导丝的细长轴和远端轴部分上施加第一亲水性涂层。 然后使该第一亲水涂层固化。 接下来，从引导线的远侧轴部的一部分去除第一亲水性涂层。 在去除第一涂层之后，可以将第二亲水涂层施加到导丝的细长轴和远侧轴部分。 可以使第二亲水涂层固化。
