Abstract

A delivery device for implanting a medical device including a flexible elongate member that is sized and shaped to fit within a body vessel. A collet is located at a first end of the flexible elongate member and has at least two arms being movable between a first open state and a second collapsed state. The arms form an inner chamber when in the collapsed state. The elongate member substantially surrounds the collet in a first position and is substantially separated from the collet in a second position thereby moving said arms between said closed state and said open state.

Claims

1. A delivery device for implanting a medical device, said delivery device comprising:

a flexible elongate member being sized and shaped to fit within a vessel, said elongate member having a first end and a second end;

a collet located at the first end of said flexible elongate member and movable between a first position and a second position within said elongate member, said collet having at least two arms, said arms being movable between a first open state and a second collapsed state, said arms forming an inner chamber when in said collapsed state; and

an actuator affixed to the flexible elongate tubular member, said actuator changing the relative position of said collet and said flexible elongate member between said first position wherein said flexible elongate member substantially surrounds said collet thereby forcing said arms in said closed state and said second position wherein said flexible elongate member substantially does not surround said collet thereby permitting said arms in said open state.

2. The delivery device of claim 1 wherein said inner chamber is sized and configured to capture an attachment means of said medical device.

3. The delivery device of claim 1 further comprising a handle attached to the proximal end of said elongate member.

4. The delivery device of claim 3 wherein said actuator is at least partially disposed in said handle for changing the relative position of said collet and said flexible elongate member.

5. A delivery device for implanting a medical device, said delivery device comprising:

a flexible elongate member being sized and shaped to fit within a vessel said elongate member having a first end and a second end;

a collet located at the first end of said flexible elongate member, said collet having at least two arms, said arms being movable between a first open state and a second collapsed state, said arms forming an inner chamber when in said collapsed state;

a sleeve movable between a first position and a second position within said elongate member; and

an actuator affixed to the sleeve, said actuator changing the relative position of said collet and said sleeve between said first position wherein said sleeve substantially surrounds said collet thereby forcing said arms in said closed state and said second position wherein said sleeve substantially does not surround said collet thereby permitting said arms in said open state.
