1. An implantable device for treating a blood vessel having a physiological cavity, the implantable device comprising:

  • a body frame having a flow diverting section at a distal end and an anchoring section at a proximal end, a longitudinal axis extending from the distal end to the proximal end of the body frame, a first orthogonal axis substantially perpendicular to the longitudinal axis, and a second orthogonal axis substantially perpendicular to the longitudinal axis and the first orthogonal axis;

    the flow diverting section of the body frame comprising a first pair of free ends, each of the first pair of free ends being longitudinally aligned along the first orthogonal axis and forming the distal end of the body frame allowing for positioning adjacent to or within the physiological cavity,a first pair of anchoring segments and a second pair of anchoring segments being longitudinally aligned along the second orthogonal axis;

    where the flow diverting section is folded about the first orthogonal axis such that the first pair of anchoring segments and the second pair of anchoring segments extend proximally from the flow diverting section on either side of the first pair of free ends to form the anchoring section and when deployed the first pair of anchoring segments expands away from the second pair of anchoring segments along the second orthogonal axis to anchor within a stem blood vessel at a blood vessel bifurcation, the stem blood vessel extending opposite the physiological cavity; and

    a semi-occlusive flow diverting surface extending within a portion of the body frame between the first pair of free ends such the flow diverting surface partially occludes the physiological cavity while allowing flow along the first orthogonal axis adjacent to the flow diverting surface.
