Intravascular device deployment mechanism incorporating mechanical detachment
First Claim
1. 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 having an interior lumen and a distal portion;
a connector fiber extending from 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 ring, the connector fiber passing through the cutter ring, and the cutter ring having an elongated pull member connected to the cutter ring to allow a user to move the cutter ring 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.

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.

8. 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 having an annular connector ring to be placed within the vasculature of a patient;
providing an elongated, flexible pusher member;
providing a connector fiber extending from the 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;
providing a cutter ring, the connector fiber passing through the cutter ring, and the cutter ring having an elongated pull member connected to the cutter ring to allow a user to move the cutter ring for cutting the connector fiber to release the therapeutic device;
positioning the therapeutic device at a desired placement within a patient'"'"'s vasculature; and
pulling the elongated pull member to move the cutter ring 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. - View Dependent Claims (9, 10)
