Claim Text:
1. A method for occluding a venous vessel having an inside wall, comprising: providing a delivery device including a first sheath having a lumen and a second sheath having a lumen, with the second sheath received in the lumen of the first sheath; providing an occlusion device positioned in the delivery device, the occlusion device including only a single anchoring member configured to expand to forcibly contact the inside wall of the venous vessel and an elongate occluding body extending away from the anchoring member, wherein the anchoring member comprises an expandable sponge body anchoring member, wherein the expandable sponge body anchoring member resides outside of the second sheath and within the lumen of the first sheath, and wherein the elongate occluding body resides within the lumen of the second sheath; accessing the venous vessel through an access point; inserting the delivery device into the venous vessel through said access point; advancing the delivery device through the venous vessel away from the access point; deploying the sponge body anchoring member out of the lumen of the first sheath and into the venous vessel, wherein the sponge body anchoring member expands to forcibly contact the inside wall of the venous vessel so as to become anchored in the venous vessel and to fill the lumen of the venous vessel with the sponge body anchoring member at a location spaced from said access point; and removing the delivery device from the venous vessel through said access point, wherein the anchoring member inhibits migration of the elongate occluding body in the venous vessel during said removing such that the elongate occluding body is drawn from the lumen of the second sheath to remain implanted in the venous vessel along an elongate stretch of the venous vessel occurring between said anchoring member and the access point, with the elongate occluding body occluding the flow of blood through said venous vessel along said elongate stretch.
