Zusammenfassung:An apparatus includes a stent configured to releasably support a blood pump within an inner lumen of the stent. The stent can include one or more arms configured to bend radially inward and releasably couple to attachment portions on a housing of the blood pump. The attachment portions of the blood pump housing may include one or more slotted openings for accepting the arms extending from the stent. A magnetic member may assist in coupling the arms to the blood pump housing. When decoupling the blood pump from the stent, a position of the blood pump may be adjusted relative to the stent to cause the arms to be released from the attachment portions. Once released, the arms may bend radially outward in alignment with a diameter of the stent.
