Abstract
Methods and apparatus for a percutaneous retrograde endovascular filter and embolectomy/thrombectomy device (RET-D) according to various aspects of the present technology include a constraining sleeve housing a deployable filter and a set of closure struts positioned at the end of a flexible tube. The RET-D is deployed into a target vessel in retrograde fashion through a conventional hemostasis sheath such that the open end of the filter engages the antegrade flow of blood. The closure struts are configured to prevent loss of filtered debris when the filter is closed according to where the closure struts are positioned relative to an end of the constraining sleeve.
