Abstract:
1. A method of treating a venous valve related medical condition comprising: intraluminally implanting a prosthetic venous valve within a vein, the venous valve including a valve leaflet comprising a remodelable material attached to a radially expandable support frame; and implanting a flow-modifying device comprising a bioabsorbable material configured as an occluding device or implantable ring within 15 cm of the prosthetic venous valve, to substantially prevent fluid flow toward the heart through the prosthetic venous valve for a period of at least about 3 weeks after intraluminal implantation of the flow-modifying device in the vein, and thereafter to permit fluid flow through the prosthetic venous valve after absorption of a portion of the bioabsorbable material in the flow-modifying device.
