Beschreibung
Zusammenfassung:	A medical device assembly having a polarizable delivery mechanism reversibly engaged with a medical device and a method used by an operator to deploy said medical device at a targeted site in a body vessel is provided. The polarizable release mechanism generally comprises a pusher element having a distal end including at least two tines; the tines having a proximal section and a distal section, the tines being capable of exhibiting polarizable properties. The medical device has an opening sized to receive and to detachably engage the distal section of the tines. The delivery mechanism has an engaged position in which the tines securely hold the medical device and a detached position in which the tines and medical device are substantially unengaged. The operator causes the delivery mechanism to move from the engaged position to the detached position by applying or removing an energy stimulus to change the polarization.
