Apparatus for deployment of micro-coil using a catheter
First Claim
1. An apparatus for release of a therapeutic device within the vasculature of a patient, comprising:
- an elongated pusher member having a proximal portion and a distal portion;
a thermoplastic connector fiber connecting a therapeutic device to said elongated pusher member and having a distal portion extending beyond said distal portion of said elongated pusher member, the connector fiber being capable of being severed by heat to release said therapeutic device; and
a heater adjacent to the connector fiber for heating the connector fiber to release the therapeutic device when a desired placement of the therapeutic device within the vasculature is achieved.

Abstract
The apparatus for deployment of a therapeutic device such as a micro-coil detachably mounts the therapeutic device to a distal portion of a pusher member. In one embodiment, the therapeutic device is detachably mounted to the distal portion of the pusher member by a tubular collar that can be heated by a heater such as an electrical resistance coil to expand the collar and release and deploy the therapeutic device. The apparatus for deployment of a therapeutic device such as a micro-coil may also provide for a pusher member and a connector fiber for securing the therapeutic device to the pusher member. The connector fiber passes through a heater within the distal portion of the pusher member, for heating and breaking the connector fiber to release the therapeutic device when a desired placement of the therapeutic device within the vasculature is achieved.
