1. A medical device for removing an obstruction from a blood vessel, the medical device comprising:

  • a main bundle comprising a group of wires having a first end and a second end;

    a capturing portion formed by the group of wires and having an open proximal end, a permeable distal end, and a capturing surface extending therebetween; and

    where the capturing portion is formed from the group of wires such that the group of wires diverges from the second end of the main bundle to form the permeable distal end, the group of wires extend back in a proximal direction to form the capturing surface and open proximal end about the main bundle, such that articulation of the capturing portion relative to the main bundle does not cause the open proximal end to reduce in size.
