    摘要： A single lumen rapid-exchange catheter includes a distal sealing port and a proximal sealing port both dimensioned for receiving a guidewire to establish a fluid-tight seal therewith. Each tubular shaped sealing port has a length, and a diameter, and is made of a hydrophilic polymer. In operation, the guidewire is inserted through the distal sealing port and exits from the catheter tube at the shoulder of the catheter tube and through the proximal sealing port. When fluid is present, each sealing port will enlarge to establish a fluid-tight seal with the guidewire. A diverter can be disposed at the proximal sealing port to redirect the guidewire from the lumen and out of the catheter tube through the proximal sealing port.

    摘要翻译： 单腔快速交换导管包括远端密封端口和近端密封端口，其尺寸适于接收导丝以与其形成不透液密封。 每个管状密封口具有长度和直径，并由亲水聚合物制成。 在操作中，导丝插入穿过远端密封端口并且在导管管的肩部处并通过近端密封口从导管管出口。 当存在流体时，每个密封口都将扩大，以与导丝形成流体密封。 分流器可以设置在近端密封端口处，以将引导线从内腔重新导向，并通过近端密封端口离开导管管。

    摘要： A device for collapsing a balloon in the vasculature of a patient after an angioplasty procedure includes a balloon and at least one elastomeric member that is attached to the inner surface of the balloon at a plurality of attachment points. Preferably, the elastomeric member is an annular band that will stretch during balloon inflation. Consequently, when the balloon is deflated, the elastomeric member pulls on the balloon at its attachment points to return the balloon to a predetermined configuration, wherein the balloon collapses inwardly onto itself for subsequent removal of the balloon from the vessel.

    摘要： A catheter for use in a body vessel includes a relatively stiff proximal shaft that is shaped as a tube formed with a lumen and having a proximal end and a distal end. Further, the catheter includes a relatively flexible distal tube formed with a lumen and having a proximal end and a distal end. An inflatable balloon may be attached to the outer wall of the distal tube near the distal end. The proximal end of the distal tube is attached to the distal end of the proximal shaft at a transitional joint. The transitional joint provides a gradual transition in flexibility over the length of the joint between the stiff proximal shaft and the flexible distal tube. Importantly, the transitional joint includes an extension made of a material having superelastic properties when positioned inside the body vessel. One end of the extension is attached to the distal end of the proximal shaft. The other end of the extension projects into the lumen of the distal tube. The extension may be formed as a ribbon, core wire or may constitute a tapered section of the proximal shaft.
