Abstract
Blood flow affecting implant and implantation thereof in superior vena cava, optionally including disintegration of endothelium layer and inducing tissue ingrowth within implant. Implant includes elongated body with optional tubular inner layer forming orifice, shapeable to final orifice diameter for restricting blood flowing therethrough to chosen average flow rate; and/or tubular outer layer provided coaxially around inner layer. Outer layer is formed of second material provided in elastically deformable state for facilitating elastic radial self¬expanding from collapsed diameter up to relaxed maximal expanded diameter greater than diameter of inner wall portion of superior vena cava. Inner layer is formed of first material, in plastically or elastically deformable state.
