Blood Pumps TRIZ Cases
- Ventricular Cuff Cannula Locking Mechanism
A ventricular cuff uses a cam locking mechanism to prevent accidental cannula disconnection during ventricular assist device operation.
- VAD Connector Radial Locking Ring for Heart Attachment
Expandable locking ring engages latching lugs to secure blood pumps, eliminating complex suturing during implantation.
- Cannula Anchors With Rectangular Support Structure
A cannula design uses a rectangular cross-section support structure to prevent collapse during pump operation.
- VAD Pump Housing Diffuser Reduces Pressure Loss
A collapsible diffuser guides fluid transversely through a pump housing outlet to expand the flow path.
