摘要：
A sheath catheter used to compress and/or retrieve a filter from a body lumen. The sheath catheter includes an elongate proximal shaft and a distal recovery sheath. The proximal shaft includes a central lumen that accommodates a shaft portion of a solid core wire to provide the catheter with better pushability. The solid core wire further includes a coiled portion that extends within the recovery sheath from a distal end of the proximal shaft. The coiled portion of the core wire provides a transition in flexibility from the stiffer proximal shaft to the more flexible recovery sheath. The recovery sheath further includes a sheath lumen that is sized to receive the filter therein.
摘要（中）：
用于从体腔压缩和/或取回过滤器的护套导管。 护套导管包括细长近端轴和远端恢复护套。 近端轴包括容纳实心芯线的轴部分以为导管提供更好的推动性的中心腔。 实心芯线还包括从近侧轴的远端在恢复护套内延伸的螺旋部分。 芯线的卷绕部分提供了从更刚性的近端轴到更灵活的恢复护套的柔性过渡。 恢复护套还包括尺寸适于在其中接纳过滤器的鞘腔。
