Recent Development of Aspiration Pump in the Aspiration Thrombectomy System

Vascular embolic diseases are associated with blockage of blood supply to vital organs and thus are lethal. Aspiration thrombectomy is becoming the primary choice for revascularization in the treatment of vascular occlusions condition. As the power source in the aspiration thrombectomy procedure, the aspiration pump directly influences the outcome of the operation. This research surveyed the current technical developments of the aspiration pump in China through reviewing information obtained from the patent database and technical literatures, commented on the issues in the current patent designs, and gave suggestions for future design improvement. This study can be used as a reference for researchers and developers of medical devices besides the neurosurgeons.
