The present invention relates to an apparatus for removal of a clot from a blood vessel comprising, an embolectomy catheter, one or more sheath introducers disposed within the embolectomy catheter, two removal devices moveably engaged within the sheath introducers, and a balloon catheter with ...
Most strokes are caused by aclot in a blood vesselsupplying the brain. The usual treatment is a clot-dissolving medicine called tPA, but it must be given within four and a half hours after symptoms start, and very few stroke patients seek help in time. So doctors have been trying several...
The mostcommon typeisischemic stroke, where a clot blocks blood flow in the brain. Mechanical thrombectomy – where a surgeon threads a catheter through an artery to remove a large clot – became a standard treatment in 2015 after a series of landmark studies. "Unfortunately, pregnant and post...
A device for removing clot from a blood vessel includes a shaft. An expandable framework of struts is fixedly coupled to a distal region of the shaft. The struts can be radially expandable from a first to a second radially expanded state in a deployed configuration. An actuation cable can ...
Most stroke patients taking the anticoagulant warfarin were no more likely than those not on the medication to experience a brain bleed when undergoing a procedure to remove a blood clot, UT Southwestern Medical Center researchers report in a new study. The findings, published inJAMA, could help...
A method of removing clot from a vessel, including delivering a clot retrieval device across the clot, wherein the clot retrieval device includes an inner body having a collapsed delivery configuration and an expanded deployed configuration; and an outer body extending along a longitudinal axis and...
