OBSTRUCTION REMOVAL SYSTEM

An obstruction removal system for capturing and removing obstructions, such as clots or other matter, from a vascular system. The obstruction removal system may include one or more engaging members connected to an elongated member, such as to a distal end of the elongated member. The engaging member(s) may have an asymmetric body shape and/or an asymmetric cell configuration between its proximal and distal portions, such as a "tear drop" shape. The engaging member(s) may be comprised of a plurality of struts. One or more radiopaque markers may be connected to at least one of the struts, which may be comprised of a "dog bone" shape. A mesh structure may be positioned internally or externally to the engaging member(s) to act as a filter. A support wire may be positioned internally to aid in propping open the engaging member(s). Where multiple engaging members are used, they may have different sizes.
