    Abstract: A clot removal device for removal of an occlusion from a lumen in a patient's body is provided. The clot removal device has a lumen, an elongated member positioned within the lumen and extending axially from a proximal end to a distal end of the lumen, a handle attached to the proximal end of the lumen, a first expandable member positioned along a length of the elongated member, a second expandable member positioned along the length of the elongated member, wherein the second expandable member is distal to the first expandable member relative to the handle. The handle has at least one actuation mechanism and at least one of the following applies: a) the first expandable member is coupled to the at least one actuation mechanism and is configured to be moveable relative to the second expandable member upon manipulation of the at least one actuation mechanism; b) the first expandable member is configured to mechanically expand or contract by manipulating the at least one actuation mechanism; c) the second expandable member is coupled to the at least one actuation mechanism and is configured to be moveable relative to the first expandable member upon manipulation of the at least one actuation mechanism; or d) the second expandable member is configured to mechanically expand or contract by manipulating the at least one actuation mechanism.

    Abstract: A percutaneous thrombus extraction device for removing a thrombus from within a blood vessel includes a flexible outer sheath defining a first passage between a proximal end and a distal end. An inner sheath is movably positionable within the first passage. The inner sheath defines a second passage between a proximal end and a distal end. The inner sheath is moveable in a radial direction between a collapsed configuration and an expanded configuration along a length of the inner sheath defined between the proximal end and the distal end. A catheter is movably positionable within the second passage, and has an expandable body at a distal end portion of the catheter. The expandable body is movable between a collapsed configuration and an expanded configuration.
