    Abstract: Method of delivering a therapeutic agent includes delivering at least a portion of a medical device within a vasculature. The medical device includes a tubular member having a proximal end and distal end defining a longitudinal axis therebetween, an expandable member proximate the distal end of the tubular member, a tissue engaging member proximate the expandable member, a sheath disposed over the tissue engaging member, and a therapeutic agent disposed on at least the expandable member or the tissue engaging member. The method further includes deploying the tissue engaging member at a select location by displacement of the sheath relative the tissue engaging member, inflating the expandable member to engage the therapeutic agent with a vessel wall, deflating the expandable member, and withdrawing the medical device from the vasculature.

    Abstract: System and method for coating an expandable member of a medical device comprising a support structure to support the expandable member and an applicator positioned with at least one outlet proximate a surface of an expandable member. A drive assembly establishes relative movement between the at least one outlet and the surface of the expandable member to apply fluid on the surface of the expandable member along a coating path. A positioning device maintains a substantially fixed distance between the at least one outlet and the surface of the expandable member during relative movement therebetween by ejecting a pressurized medium against the surface of the expandable member.

    Abstract translation: 用于涂覆医疗装置的可膨胀构件的系统和方法，包括支撑结构以支撑可膨胀构件，以及施加器，其定位成邻近可扩张构件的表面的至少一个出口。 驱动组件在至少一个出口和可膨胀构件的表面之间建立相对运动，以沿着涂覆路径向可扩张构件的表面施加流体。 定位装置通过相对于可膨胀构件的表面喷射加压介质而在相对运动期间在至少一个出口和可膨胀构件的表面之间保持基本上固定的距离。
