Abstract: A crimp tool facilitates crimping a resiliently radially compressible human-implantable catheter pump, and transferring the crimped pump into a tubular transfer sheath, by pulling the heart pump through an elongated tube that defines a tapered longitudinal bore. The bore has an inside dimension that tapers gradually along the length of the bore. A large end of the bore is sufficient to accept an uncrimped heart pump. A small end of the bore has a dimension similar to an inside dimension of the transfer sheath. A proximal end of the tube has a hub. A proximal end of a bore through the hub is configured to receive a distal end portion of the transfer sheath coaxially with the tube bore. Optionally, a latch is configured to releasably restrain the distal end portion of the transfer sheath within the hub.

Abstract: A distal extension for a blood pump may be provided. The distal extension may include a tubular body. The distal end of the tubular body may be coupled to an intermediate point on the tubular body to form a closed loop at a distal end of an atraumatic distal extension. The closed loop may define an aperture extending through the closed loop, the closed loop having a central plane parallel to a central axis of the tubular body at the proximal end. In various aspects, the tubular body may include a bend. The bend may define an angle between a central axis of a first substantially straight section of the tubular body proximal to the bend and a central axis of a second substantially straight section of the tubular body distal to the bend. In various aspects, the closed loop may be a non-circular closed loop.
