Abstract

Intra arterial and intravenous thrombus formation or blood clots cause blockage in the blood flow which leads to a stroke. The occurrence of a thrombus lodged in a coronary artery can result in a swift myocardial infarction. Stent retrievers are devices employed to mechanically remove the clot and restore blood flow. A large percentage of mortality rates is traced back to inefficiency of the device in extracting thrombus out of the vessel, assuming the subject has been operated on in time. Experiments reveal aspiration of thrombus at the site of blockage to be more effective in clot retrievers and must be incorporated on stent retrievers that allows complete viewing of a procedure. This enhances ease of accessibility of larger vessels like coronary arteries and veins, and reduces the rate of symptomatic intra cranial haemorrhage when vessel damage is avoided, and embolization, major contributors to the mortality rate. There is a proven decrease in clot fragmentation rates with the utilization of a device having a marginally increased length than the pioneer stentrievers. Time remains a chief concern considering treatment subsequent to eight hours of stroke onset is near futile and a model with the guide wire and microcatheter integrated into one entity is theoretically efficacious, as ongoing research suggests. However, evidence of its feasibility to be incorporated into smaller vessels is unavailable and practical trials are necessary. Additional research that will be conducted on design and compatibility could make an ideal device a reality.
