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 connector fiber for securing the therapeutic device to the pusher member. The connector fiber passes through a cutter member such as a cutting ring within the distal portion of the pusher member, for cutting the connector fiber to release the therapeutic device when a desired placement of the therapeutic device within the vasculature is achieved.
Claims13
An apparatus for release and deployment of a therapeutic device within the vasculature of a patient, comprising:
- an elongated, flexible pusher member having an interior lumen and a distal portion;
- a connector fiber detachably mounting the therapeutic device to the pusher member for placement of the therapeutic device within the vasculature;
- a cutter member disposed adjacent to the connector fiber for cutting the connector fiber to cause the connector fiber to break and release the therapeutic device for detaching and deploying the therapeutic device from the flexible pusher member when a desired placement of the therapeutic device within the vasculature is achieved.
A method for release and deployment of a therapeutic device within the vasculature of a patient, the steps of the method comprising:
- providing a therapeutic device to be placed within the vasculature of a patient;
- providing an elongated, flexible pusher member;
- providing a connector fiber detachably mounting the therapeutic device to the pusher member for placement of the therapeutic device within the vasculature;
- providing a cutter member for cutting the connector fiber to release the therapeutic device;
- positioning the therapeutic device at a desired placement within a patient's vasculature;
- and
- moving the cutter member to cut the connector fiber to break said connector fiber to detach and deploy the therapeutic device from the flexible pusher member when a desired placement of the therapeutic device within a patient's vasculature is achieved.
