Abstract
A medical device for placing an embolic coil at a preselected location within a vessel comprising a positioning catheter having a distal section for retaining the embolic coil and an aperture for purging air from the device. The aperture is sized to allow air under fluid pressure to freely escape from within the catheter but to highly restrict the flow of more viscous fluids. At higher fluid pressures, the wall of the distal section expands outwardly to release the coil.
