Abstract

The present disclosure relates to a mechanical thrombectomy device that includes a catheter assembly with a basket assembly formed of a proximal hub and a distal hub; a flexible tube having a first end attached to the proximal hub and a second end attached to the distal hub; and a plurality of basket wires. The flexible tube may be laser-cut to allow for bending, elongation, and compression. The basket wires each have a first end attached to the proximal hub and a second end attached to the distal hub. The basket wires are disposed around the flexible tube and configured to expand to a preset shape. The basket assembly is attached to a distal end of a rotatable shaft. A drive assembly is configured to rotate the rotatable shaft to rotate the basket assembly. The basket assembly when rotated is configured to macerate a material proximate to the basket assembly.
