A recently granted patent (Publication Number: US11896257B2) discloses a thrombectomy device designed to remove blood clots efficiently. The device comprises a handle, a proximal arm with an extraction passage, a distal arm, and an extractor with a cutting edge to macerate matter before extraction. The device also features a radially expandable cage, with one arm fixed and the other longitudinally translatable, allowing for effective thrombus removal. Additionally, the extractor includes a helical coil and a varied pitch along its length, enhancing its thrombus-breaking capabilities.

Furthermore, the patent describes a thrombectomy device with a rotatable extractor wrapped around a distal arm and a radially expandable cage adjustable between contracted and expanded orientations. The extractor, with a helical formation and a cutting edge, is designed to break thrombus into smaller pieces for extraction. The device's unique design, with the extractor partially exposed and placed inside the proximal arm, aims to improve the efficiency and effectiveness of thrombus removal procedures. Additionally, the cage's adjustable diameter and the extractor's varied pitch contribute to the device's ability to break down thrombus and facilitate extraction, making it a promising innovation in the field of thrombectomy devices.
