Crimping tool for compressible catheter pump

The crimping tool facilitates crimping a resilient radially compressible human implantable catheter pump and transfers the crimping pump into a tubular transfer sheath by pulling the heart pump through an elongate tube defining a tapered longitudinal bore. The bore has an internal dimension that tapers along a length of the bore. The large end of the bore is sufficient to receive an uncurled heart pump. The small end of the aperture has a size similar to the internal size of the transfer sheath. The proximal end of the tube has a hub. A proximal end of the bore through the hub is configured to receive a distal end portion of the transfer sheath coaxially with the bore. Optionally, the latch is configured to releasably constrain the distal end portion of the transfer sheath within the hub. 卷曲工具有利于卷曲弹性径向可压缩的人体植入式导管泵，并且通过将心脏泵拉动通过限定锥形纵向孔的细长管，而将卷曲泵转移到管状转移护套中。该孔具有沿着该孔的长度渐缩的内部尺寸。孔的大端足以容纳未卷曲的心脏泵。孔的小端具有与转移护套的内部尺寸相似的尺寸。管的近端具有毂。穿过毂的孔的近端被配置成与管孔同轴地接收转移护套的远端部分。可选地，闩锁被配置成将转移护套的远端部分可释放地约束在毂内。
