    • The present invention includes systems, methods and apparatus. A system in accord with the present invention may include an intraluminal patch sized to fit within a lumen and an expandable therapeutic delivery device. The patch in this embodiment may have an adhesive region on an exposed surface and a drug reservoir region in communication with the exposed surface. By comparison, a method employing the present invention may include placing an intraluminal patch over an expandable delivery device, advancing the delivery device and the expandable patch to a target site, expanding the delivery device so that the patch adheres to the target site, and contracting and withdrawing the delivery device. In so doing the patch may remain to emit a drug to the target site over a sustained period of time.
    • 本发明包括系统,方法和装置。 根据本发明的系统可以包括尺寸适合于内腔和可扩张治疗递送装置的管腔内贴片。 本实施例中的贴剂可以在暴露表面上具有粘合剂区域和与暴露表面连通的药物储存区域。 相比之下,使用本发明的方法可以包括将管腔内贴片放置在可扩张递送装置上,将递送装置和可扩张贴片推进到目标部位,扩大递送装置,使得贴片粘附到目标部位,并收缩 并撤回送货装置。 在这样做时,补片可能会持续在持续的时间内向目标地点发放药物。

    • A medical instrument converts linear movement of a shaft at a proximal end of the instrument to a rotational movement of an end effector of the instrument. According to one embodiment, the medical instrument includes an end effector formed of a snare loop connected to a shaft that is located within a sleeve. Once the sleeve is located near a desired location within a patient, the snare loop may be rotationally positioned with linear movement of the shaft by the operator. The shaft is formed with a threaded portion that matches threads formed in a torque transmitter element fixed within the sleeve. Linear movement of the shaft through the torque transmitter element causes the shaft to rotate. The medical instrument may also include a pivot connector for reducing torque build-up of the shaft and/or a clutch assembly for restricting controlled rotation of the snare loop to only one direction.
    • 医疗器械将仪器近端的轴的线性运动转换为仪器的末端执行器的旋转运动。 根据一个实施例,医疗器械包括由连接到位于套筒内的轴的圈套环形成的端部执行器。 一旦套筒位于患者体内的期望位置附近,则圈套环可以由操作者以轴的线性运动旋转地定位。 轴形成有螺纹部分,其匹配形成在固定在套筒内的扭矩传递器元件中的螺纹。 轴通过扭矩传感器元件的线性运动导致轴旋转。 医疗器械还可以包括用于减小轴和/或离合器组件的扭矩积分的枢转连接器,用于将圈套环的受控转动限制到仅一个方向。
