Abstract: A medical device for placing an embolic coil at a preselected location within a vessel comprising a positioning catheter having a distal tip for retaining the embolic coil which when pressurized with a fluid expands outwardly to release the coil at the preselected position.

Abstract: A medical device for placing a very small embolic coil at a preselected location within a vessel comprising a positioning catheter having a distal tip for retaining a headpiece with an attached embolic coil such that when the catheter is pressurized with a fluid the distal tip of the catheter expands outwardly to release the headpiece and coil at the preselected position.

Abstract: A vascular stent for opening blood vessel occlusions and for providing support to damaged areas of blood vessel sites includes a proximal end defining a first lumen opening. The helical stent is constructed from a resilient material and has a body portion extending from the proximal end to define a lumen. A distal end defines a second lumen opening a predetermined axial distance from the first lumen opening. The stent is maintained in a stretched linear state when in a catheter for delivery to a vascular site, and resiliently expands into a relaxed helical shape when released from the catheter. Various embodiments of the present invention are disclosed, including a stent made of a wire having a flattened cross-section, a helical wire stent having a flat ribbon to span between adjacent loops of wire, multiple intertwined stents in the same blood vessel.

Abstract: The present invention relates to a medical device for placing an intravascular stent at a preselected location within a vessel of the human body, and more particularly, relates to a catheter having a distal tip for retaining the stent in order to transport the stent to a preselected position within the vessel and a control mechanism for releasing the stent at the preselected position.
