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. The positioning catheter includes a coaxial stiffening tube and helically wound coil transition zone to provide improved positioning of the embolic coil.
