Problems solved by technology

The disadvantage of this approach is that the mesh filter may degrade and flow through the vessel, potentially damaging downstream cells and tissues that the blocked vessel would normally supply
Therefore, it may be difficult or impossible to use in small diameter vessels
[0008] Accordingly, a thrombectomy catheter and method of use thereof are capable of deploying, scooping, collecting, and Removal of material, plaques, emboli and emboli where there is a clear unmet need
