Patent number: 11945634Abstract: 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.Type: GrantFiled: October 22, 2020Date of Patent: April 2, 2024Assignee: ECP ENTWICKLUNGSGESELLSCHAFT MBHInventors: Daniel Roehn, Joerg Schumacher

Publication number: 20240017051Abstract: An intravascular blood pump has an intake filter that reduces risk of heart tissue being sucked into an intake port of the pump. The filter defines a plurality of apertures, through which blood flows through the filter. The apertures are sized to prevent ingestion, by the input port, of the heart tissue. The filter includes a plurality of generally helical first struts wound about a longitudinal axis of the filter, and a plurality of second struts. The first and second struts collectively define the plurality of apertures therebetween. The struts may be woven filaments, or the apertures may be defined in a thin film (foil) tube, where remaining material between the apertures form the struts.Type: ApplicationFiled: June 19, 2023Publication date: January 18, 2024Applicant: ABIOMED, INC.Inventors: Ralph Louis D'Ambrosio, Maxim Daschewski, Valentin Neblik, Joerg Schumacher, Gerd Spanier
