INTRALUMINAL DELIVERY DEVICE

摘要

The apparatus (10) for deployment of a therapeutic device (14) such as a mic ro- coil detachably mounts the therapeutic device (14) to a distal portion of a pusher member (12). In one embodiment, the therapeutic device (14) is detachably mounted to the distal portion of the pusher member (12) by a tubular collar (24) that can be heated by a heater such as an electrical resistance coil (26) to expand the collar (24) and release and deploy the therapeutic device (14). The apparatus (40) for deployment of a therapeutic device (44) such as a micro-coil may also provide for a pusher member (42) a nd a connector fiber (64) for securing the therapeutic device (44) to the pushe r member (42). The connector fiber (64) passes through a heater (66) within th e distal portion of the pusher member (42), for heating and breaking the connector fiber (64) to release the therapeutic device (44) when a desired placement of the therapeutic device (44) within the vasculature is achieved.
