Beschreibung
Zusammenfassung:	An apparatus, comprising: a blood pump, comprising: an axial shaft (92) configured for insertion into, and rotation within, a body of a subject; an impeller (50) coupled to the axial shaft (92) such that, as the axial shaft (92) rotates, the impeller (50) pumps blood of the subject; a frame (34) surrounding the impeller (50) and comprising a distal conical portion (40); a bearing adjacent to the axial shaft (92) and configured to stabilize the axial shaft (92) while the axial shaft (92) rotates; and a bearing housing (118H) that houses the bearing, at least 50 percent of a length of the bearing housing (118H) being disposed at least partly within the distal conical portion (40) of the frame (34).
