Abstract:
A blood flow deflector for introduction into an artery or blood vessel, comprising:a centrally located elongated body; resilient holding means attached to said elongated body, said holding means being expansible from a first diameter corresponding to a diameter of said elongated body to a second diameter corresponding to a diameter of a target artery or a blood vessel, said holding means bearing, in a service position, on an internal wall of the artery or blood vessel and maintaining said elongated body centered in the artery or the blood vessel, said elongated body being sized to locally increase the shear stress at least 50% at the internal wall by deflecting lines of blood flow in a radial direction while imposing minimal hemo dynamical resistance to flow, wherein a ratio between a radius of the elongated body over a radius of the resilient holding means in the service position is 0.3.
