Title:
VENTRICULAR ASSIST DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/138350
Kind Code:
A3
Abstract:
Apparatus and methods are described including a blood pump (20) configured to be placed inside a body of subject, the blood pump including an impeller (50) that includes proximal and distal bushings (64, 58), and a frame (34) disposed around the impeller, the frame including proximal and distal bearings (116, 118). An axial shaft (92) passes through the proximal and distal bearings (116, 118) of the frame and the proximal and distal bushings (64, 58) of the impeller (50). The impeller (50) defines a radially-constrained configuration in which the impeller (50) is introduced into the subject's body and a non-radially-constrained configuration in which the impeller (50) is configured to pump blood within the subject's body. The impeller (50) changes from its radially-constrained configuration to its non-radially constrained configuration by the distal bushing (58) sliding over the axial shaft (92). Other applications are also described.
