Occluding coil delivery device and method
First Claim
1. A device for use within a lumen of a catheter to move an item positioned within said lumen relatively to said catheter, said device comprising:
- an elongated member positionable within said lumen and reciprocably movable relatively to said catheter; and
a gripping element attached to said elongated member, said gripping element being alternately engageable with and disengageable from said item, said item being movable relatively to said catheter when said gripping element is engaged with said item and said elongated member is moved, said gripping element and said elongated member being movable relatively to said catheter and said item when said gripping element is disengaged from said coil.

Abstract
A device for use within the lumen of a catheter to move an item positioned within the lumen relatively to the catheter is disclosed. The device is formed from an elongated member positionable within the lumen and reciprocably movable relatively to the catheter. A distal end of the member is engaged with the item, and a proximate end extends outwardly from the catheter. A gripping element is attached to the elongated member at the distal end. The gripping element has a free end that extends outwardly from the elongated member. The free end of the gripping element is engageable and disengageable with the item, the item being moved when the gripping element is engaged and the elongated member is moved relatively to the catheter.

10. A device for use within a lumen of a catheter to move an item positioned within said lumen relatively to said catheter, said device comprising:
-
an elongated member positionable within said lumen and reciprocably movable relatively to said catheter, said elongated member having a distal end engageable with said item and a proximate end extending from said catheter;
an appendage having a first end attached to said elongated member at said distal end, and a free end oppositely disposed, said appendage being movable to position said free end outwardly from said elongated member so as to engage and grip said item for movement thereof through said lumen upon movement of said elongated member, said appendage being further movable to position said free end toward said elongated member so as to disengage said appendage from said item thereby allowing movement of said elongated member without movement of said item. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method of delivering a coil from a catheter into an aneurysm, said method comprising the steps of:
-
providing a catheter having a coil positioned therein, an elongated member positioned therein, and a gripping element mounted on the elongated member;
positioning the catheter tip within the aneurysm;
engaging the gripping element with the coil;
moving the elongated member toward the catheter tip, a portion of the coil positioned between the gripping element and the catheter tip being pushed out from the catheter tip and into the aneurysm;
disengaging the gripping element from the coil;
moving the elongated member and thereby the gripping element away from the catheter tip; and
repeating the engaging, moving and disengaging steps as required to move the coil into the aneurysm.
