Device to implant occlusion coil in body cavity or blood vessel; has occlusion coil that is electrolytically corrodible at several points to separate variable length of coil on contact with body fluid

摘要

The device has a voltage source (7), a cathode (8), a catheter (1) and an occlusion coil (3) that slides in the cathode and acts as an anode. The occlusion coil is formed so that it is electrolytically corrodible at several spaced points (9), so that one or more variable lengths of coil can be separated by electrolysis on contact with a body fluid. A guide wire (2) may be formed alongside the occlusion coil.
