    Abstract: An expandable dilation member may include a proximally-tapered portion to dilate a stricture. The dilation member may be distally advanced in an unexpanded state over a wire guide through the stricture. The dilation member may then be configured in an expanded state, where the dilation member has a longitudinal profile that includes the proximally-tapered portion. A handle assembly proximally pulls the dilation member in the expanded state. In response, the proximally-tapered portion engages with and biases the stricture. When biasing the stricture, the proximally-tapered portion exerts a plurality of different types of forces, including a shearing force, a radial force, and in some procedures, a torsional force. In some embodiments, the proximally-tapered portion has a continuous taper from a smallest diameter to a largest diameter. In other embodiments, the proximally-tapered portion has at least one constant-diameter portion longitudinally disposed in between the smallest diameter and the largest diameter.

    Abstract: The present invention relates to a medical device, for pancreas, equipped with drainage feature. The medical device includes a stent having an exterior surface, a proximal end and a distal end. The medical device further includes a drainage tube helically wrapped around the stent. The drainage tube includes an external surface, an internal surface, a proximal end, and a distal end. The external surface of the drainage tube is designed with a plurality of holes. The pluralities of holes are connected to the internal surface via a lumen. The plurality of holes can be configured to direct the fluid from side walls of pancreas and bring it out through lumen to avoid occlusion of the side walls in pancreas.

    Abstract translation: 本发明涉及一种装有排水功能的胰脏医疗器械。 医疗装置包括具有外表面，近端和远端的支架。 医疗装置还包括螺旋缠绕在支架上的引流管。 引流管包括外表面，内表面，近端和远端。 排水管的外表面设计有多个孔。 多个孔通过内腔连接到内表面。 多个孔可以被配置成从胰腺的侧壁引导流体并通过管腔将其排出，以避免胰脏侧壁堵塞。
