A medical device, deployment systems and methods of use thereof are provided. The medical device includes at least one anchor element coupled to a device body. The anchor element has a first configuration disposed about an anchor axis and configured to pierce a body tissue wall. In a second configuration, the anchor elements have an enlarged shape, and in response to a temperature rise in the anchor element, the pierced body tissue wall is drawn closer to the device body. The anchor element maintains alignment substantially with the anchor axis to inhibit tearing of the pierced body tissue wall by the anchor element. The system may include balloons for targeting the radial pressure of the anchor elements into the body vessel wall. The anchor elements may be made of shape memory materials capable of localized heating due to an induction device.
