PUMP-HEAD PORTION OF VENTRICULAR ASSIST DEVICE

WIPO Patent Application WO/2024/057257

A3

Apparatus and methods are described including an axial shaft (92) and an impeller (50) configured for rotation within a subject's body. A coupling element (65) includes a first portion (66), which is disposed around the axial shaft (92), is shaped to define one or more slits (75) that facilitate a radial expansion of the first portion (66) such that the first portion (66) is placeable around the axial shaft (92), and is shape-set to have an inner diameter that is smaller than a diameter of the axial shaft (92) such that, following placement of the first portion (66) around the axial shaft (92), the first portion (66) becomes radially contracted around, and thus locked in place with respect to, the axial shaft (92). A second portion (71) of the coupling element (65) is coupled to a bushing (58, 64) of the impeller (50). Other applications are also described.
