1. A device for treating a thrombus in a vessel, the device comprising:
- a plurality of wires woven to form a textile structure,the textile structure comprising;
a longitudinal axis,a first bulb comprising;
a generally circular cross-section in an expanded state,the first bulb intersecting the longitudinal axis at an off-center position,a second bulb comprising;
a generally circular cross-section in an expanded state,the second bulb intersecting the longitudinal axis at an off-center position, anda neck between the first bulb and the second bulb;
wherein the neck is aligned along the longitudinal axis and wherein the first bulb and the second bulb are differently radially offset from the longitudinal axis.
