Abstract		To present an overview of our 7 years of experimental work and early clinical experience with percutaneous implantation of a bioprosthetic venous valve (BVV) and our recent experimental work with percutaneous autogenous venous valve (PAW) transplantation. Three types of BVVs consisting of a (small) leaflet of small intestinal submucosa (SIS) attached to different types of metallic square stent frames were tested in the ovine jugular veins. Altogether 66 BVVs were tested in 32 sheep. Follow-up venograms were done from 1 to 6 months. In clinical work, 15 patients with advanced venous insufficiency were treated by placement of a single BVV into the femoral vein. PAVV transplantation with a vein segment containing a native valve attached to a stent template ', was explored in 9 sheep. BV Vs were easy to deliver and remained in place and stable.
