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, flexible pusher member;
a connector fiber connecting the therapeutic device to the pusher member, the connector fiber being capable of being broken by heat; and
a heater disposed adjacent to the connector fiber for heating the connector fiber to cause the connector fiber to detach the connector fiber from the therapeutic device and to detach the therapeutic device from the flexible pusher member 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.

11. An apparatus for release of a vasoocclusive device through a delivery catheter within the vasculature of a patient, comprising:
-
an elongated, flexible pusher member;
a connector fiber connecting the vasoocclusive device to the pusher member, the connector fiber being capable of being broken by heat; and
a heater disposed adjacent to the connector fiber for heating the connector fiber to cause the connector fiber to break to detach the connector fiber from the vasoocclusive device and to detach the vasoocclusive device from the flexible pusher member when a desired placement of the vasoocclusive device within the vasculature is achieved. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
