Response to letter: How much will a catheter tip expand in aspiration thrombectomy?

Summary: The study characterized the aspiration performance of different catheters on stiff clots in an in vitro vascular model, finding that ADAPT performance is highly influenced by catheter tip shape-adaptability to the clot and that the effective inner diameter (eff-ID) may differ from the labeled-ID specified by manufacturers. Based on experimental findings, considering the eff-ID rather than the labeled-ID is crucial for estimating device efficiency accurately.
