  • Patent number: 11945634
    Abstract: The invention relates to a container for a heart pump device with a first receiving space for a compressible and expandable heart pump, wherein the first receiving space is delimited on several sides, in particular on all sides, by one or more closure elements and is closed off to the outside for preventing a contacting of the heart pump, wherein the closure elements) leave free an opening for the passage of a catheter from the outside into the first receiving space, wherein the diameter of the opening is dimensioned such that the heart pump can pass this exclusively in a condition which is at least partly compressed compared to the expanded condition. For implantation, the heart pump in the container can firstly be operated by trial in the container whilst feeding a rinsing fluid and can then be pulled through the opening amid simultaneous compression, into a sheath element.

  • Publication number: 20240052847
    Abstract: In a rotor for a fluid pump which is made radially compressible and expandable and has a hub and at least one conveying element which has a plurality of struts and at least one membrane which can be spanned between them, provision is made for a design in accordance with the invention which is as simple and inexpensive as possible that at least one first group of struts is pivotable in a pivot plane, starting from a common base, and can thus be spanned open in the manner of a fan, wherein the conveying element lies along the hub and contacts it over its full length in the expanded state to avoid a pressure loss at the margin of the conveying element between it and the hub and thus to realize an optimum efficiency.

  • Publication number: 20230009675
    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.
