Blood Pumps TRIZ Cases

Secondary flow path flushes rotor clearance to eliminate mechanical bearings, reducing thrombosis and wear while minimizing power consumption.

An insulated purge line delivers oxygenated fluid to sustain motor efficiency while preventing bio-deposit buildup on blood pump components.

Capacitive sensors on the cannula detect signals to determine intracardiac blood pump position without imaging equipment.

Interconnected balloons modulate blood flow via pressure-induced expansion to reduce venous congestion.

Segmented inflow cannula slots prevent heart chamber collapse during suction events while maintaining high blood flow rates.

Potting material reinforces the stator casing of a blood pump, absorbing rotational forces to reduce housing thickness while maintaining mechanical strength.

Elastic support structure prevents balloon rolling in descending aorta, enabling longer-term circulatory support without vascular complications.

A sterile connector uses recessed sidewall channels to deliver fluid during wet-to-wet surgical tubing connections.

A percutaneous circulatory support device uses a frustoconical driven magnet to rotate an impeller and inhibit blood pooling in the proximal housing end.

A miniaturized axial flow rotary pump uses magnetic bearings to enable less invasive implantation.

Flexible tubular membrane pumps blood through a single lumen, eliminating sharp edges that cause clotting.

A distal protuberance on an inflow cannula diverts thrombus particles away from thrust bearings to prevent accumulation and pump malfunction.
