Novel Blood Clot Retriever for Ischemic Stroke

Area of Science:

• Biomedical Engineering
• Neurosurgery
• Cardiovascular Research

Background:

• Stroke is a leading global cause of death, with ischemic stroke accounting for 80% of cases.
• Acute ischemic stroke, often caused by blood clots, requires effective treatment to prevent fatalities.
• Current blood clot retrievers have limitations in retrieval performance.

Purpose of the Study:

• To introduce and evaluate a novel blood clot retriever for acute ischemic stroke.
• To demonstrate the proof of concept for a new retriever design through simulation and testing.
• To compare the novel design's performance against traditional stent-like retrievers.

Main Methods:

• Design and computer simulation of a unique blood clot retriever.
• Prototyping and bench testing of the novel device.
• Evaluation of retrieval performance using experimental methods.

Main Results:

• The novel retriever design incorporates large closed cells, irregular spikes, and strut protrusions.
• Computer simulations and bench testing confirmed the feasibility of the design.
• An experimental retrieval rate of 79% was achieved, indicating effective clot removal.

Conclusions:

• The proposed blood clot retriever shows significant potential for improving acute ischemic stroke treatment.
• The unique design features contribute to enhanced entanglement and retrieval performance.
• This novel device represents a feasible advancement in endovascular clot retrieval therapy.
