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.
Claims4
An apparatus for release and deployment of a therapeutic device having an annular connector ring within the vasculature of a patient, comprising:
- an elongated, flexible pusher member;
- a connector fiber connected to the elongated, flexible pusher member and forming a loop through the connector ring of the therapeutic device to detachably mount 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, the cutter member having an elongated pull member connected to the cutter member to allow a user to move the cutter member for cutting the connector fiber to cause the connector fiber to break and release the therapeutic device.
