摘要： A rapid exchange catheter includes an exchange joint that is coupled between a proximal shaft and first and second distal shafts. The exchange joint includes a proximal end that is configured to be coupled to the proximal shaft, and a distal end that is configured to be coupled to the first distal shaft and the second distal shaft. The distal end includes a first portion that includes a first guidewire lumen, and a second portion that includes a second guidewire lumen. The exchange joint also includes a guidewire port that is configured to provide access for a first guidewire into the first distal inner lumen via the first guidewire lumen and a second guidewire into the second distal inner lumen via the second guidewire lumen.

摘要： A rapid exchange catheter includes an elongate proximal shaft comprising a proximal lumen, an elongate distal shaft defining an distal outer lumen, an elongate distal inner lumen inside the distal shaft, and an exchange joint coupled between the elongate proximal shaft and the elongate distal shaft. The exchange joint includes a guidewire port providing external access for a guidewire into the elongate distal inner lumen, and a transition lumen in communication with the proximal lumen and the distal outer lumen. The transition lumen has a crescent-shaped cross-section at least at the exchange joint distal end.

摘要翻译： 快速交换导管包括细长近端轴，其包括近端内腔，限定远侧外腔的细长远侧轴，远端轴内的细长远侧内腔，以及联接在细长近端轴和细长远端轴之间的交换接头。 所述交换接头包括导丝孔，所述导丝端口提供用于导丝进入细长远侧内腔的外部通路，以及与近端内腔和远端外腔连通的过渡腔。 转换腔至少在交换关节远端处具有月牙形横截面。
