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 and in which a plurality of turns at the proximal portion of the embolic coil are spot welded to adjacent turns to prevent this proximal portion of the coil from elongating or stretching while also providing a coil which is very flexible.
