Blood Pumps TRIZ Cases
- Pericardial Access Using Joule Heating Wire and Braided Anchor
Heated wire electrodes incise the pericardium while braided anchors stabilize ventricular assist balloon cannulas.
- Compliant Impeller Blades for Percutaneous Heart Pump
Flexible impeller blades compress into a compact hub configuration for percutaneous insertion, then expand to deliver high flow rates at low rotational speeds.
- Foldable Intravascular Blood Pump Clearance Design
Increasing clearance between the foldable housing and impeller prevents contact damage during deformation while maintaining flow.
- Malleable Cannula with Segmented Struts for Anatomical Shaping
Segmented struts allow the cannula to fit patient anatomy while preventing kinks and reducing thrombus formation.
- Left Ventricular Assist Pump with Segmented Rotor-Stator and Casing
Segmenting the electromagnetic motor from the blood flow casing resolves the contradiction between compact device size and efficient circulation area.
- Blood Pump Cannula With Reinforced Optical Fiber Lumens
Reinforcement members inside support lumens prevent kinking of brittle optical fibers during insertion, preserving sensor reliability.
- Malleable Cannula Channel Anchoring
A malleable cannula houses a reinforcement member in a dedicated channel to prevent instability during surgical shaping.
