Abstract
The devices and methods described herein relate to clearing of blockages within body lumens, such as the vasculature, by addressing the frictional resistance on the obstruction prior to attempting to translate and/or mobilize the obstruction within the body lumen.

An intravascular apparatus for removing an obstruction from a vessel, the device comprising:
- a microcatheter having a size and flexibility to navigate within a neurovascular region of the patient;
- a near connector being self expanding and having a first expanded profile when unconstrained, such that on deployment in the vessel the near connector self expands towards the first expanded profile;
- a far connector being collapsible to fit within the microcatheter and being self-expanding to assume a second expanded profile when unconstrained, such that on deployment in the vessel the second connector expands towards the second expanded profile and expands within the vessel;
- at least one lead filament coupling the near connector to the microcatheter;
- a plurality of traversing filaments extending between the near and far connectors, and spaced apart on each connector such that spreading the traversing filaments causes the filaments to move towards an exterior of the obstruction;
- and
- a blood permeable filter member affixed to the far connector, the blood permeable filter being collapsible to fit within the microcatheter and self-expanding to expand in the vessel upon deployment.
