1. A device for removing a clot from a blood vessel, the device comprising:
a proximal section having a plurality of first cells, each of the first cells defined by first sidewalls and at least some of the first sidewalls are curved, wherein the proximal section comprises a tapered portion and a body portion distal of the tapered portion, and wherein,
the body portion of the proximal section includes a plurality of forward free peaks, a plurality of forward connected peaks, a plurality of reverse connected peaks, and does not include any reverse free peaks, and
the body portion comprises at least three longitudinally aligned forward free peaks spaced apart around a circumference of the device; and
a distal section coupled to the proximal section such that the body portion of the proximal section is between the tapered portion of the proximal section and the distal section along a length of the device, the distal section having a plurality of second cells, each of the second cells defined by second sidewalls,
wherein the plurality of first cells and the plurality of second cells include a plurality of six-sided cells and a plurality of four-sided cells, and
wherein the proximal section and the distal section are connected by an intermediate section extending between the proximal section and the distal section, the intermediate section comprising at least one strut extending parallel to a central longitudinal axis of the device.
