This disclosure concerns release mechanisms for medical implants, particularly embolic coils and the like, which utilize bulbous elements and receiving elements to constrain the bulbous elements. In some cases, the receiving elements are sized and shaped to help constrain the bulbous element axially and/or radially, and may work in concert with constraining elements and/or release wires that are optionally moveable independently of the receiving elements.

Pusher arm and ball release mechanism for embolic coils

The present disclosure relates to the field of embolic coils. More specifically, the present disclosure relates to systems and methods for actively releasing an embolic coil from a delivery device into a body lumen of a patient. Delivery systems of the present disclosure may allow an embolic coil to be advanced external to the distal end of a delivery catheter without being automatically released, thereby allowing the embolic coil to be repositioned prior to deployment.

Active release of embolic coils

The present disclosure relates to embolic coils that eliminate kick-back into a parent vessel by providing a proximal end that retracts following deployment within the vasculature. Also disclosed are methods of making such coils, delivery systems that comprise such coils, and methods of delivering such coils to a patient.
