Description

technical field

[0001] The present invention generally relates to medical devices. More specifically, the present invention relates to a thrombectomy cage having a double-pillar structure. Background technique

[0002] Blood thrombi can embolize and embolize in the patient's vasculature. Sometimes these plugs are dissolved in the blood safely and harmlessly. However, at other times, such emboli can lodge in blood vessels, and they can partially or completely block the flow of blood. If a blood vessel supplying blood to sensitive tissues such as the brain, lungs or heart is partially or completely blocked, for example, severe tissue damage can result.

[0003] When symptoms of a blockage are evident, such as a blockage leading to a stroke, immediate action should be taken to reduce or eliminate the resulting tissue damage. One approach is to treat patients with clot-dissolving drugs. However, these drugs do not immediately dissolve a patient's blood clot.
