Blood Pumps TRIZ Cases
- Blood Pump Surface Modification for Delayed Coagulation
Diamine-modified pump surfaces and sodium bicarbonate purge fluid delay coagulation and suppress fibrin formation in blood flow.
- Percutaneous Catheter Ladder-Lock Fixation for Stable Pump Positioning
Pivotable rails and rungs let physicians reposition an intracardiac-pump catheter, then lock it against migration.
- External Drive Unit Purge-Line Cooling for Heart Assist Pumps
A thermally coupled purge line carries motor heat away from an external heart assist pump drive unit, supporting cooling when enclosed.
- Percutaneous Circulatory Support Housing Channel for Guidewire Protection
A blood outlet channel supports the guidewire through smooth transitions, reducing deformation and coating removal during delivery.
- Expandable Aorta and Vena Cava Pumps for Renal Perfusion
Expandable pumps placed in the descending aorta or inferior vena cava increase renal perfusion or reduce venous pressure while limiting migration.
