Abstract
A device for delivering an embolic coil to a selected site within a vessel in a human body via use of a catheter. In particular, the device involves an embolic coil having an enlarged member, such as a ball attached thereto which coil is released by forcing the enlarged member through an aperture in a socket situated on the distal end of a pusher assembly.
Claims6
A device for placing an embolic coil at a target site in the body, comprising:
- (a) a vasoocclusive coil having a proximal end and a distal end and having an enlarged member with a diameter, the enlarged member fixedly attached to the coil's proximal end;
- (b) a pusher housing having a distal end and having a distendable aperture at its distal end, the distendable aperture having a constant inner diameter which is smaller than the diameter of the enlarged member within which the enlarged member is held;
- and
- (c) a guidewire having a proximal end and a distal end and located within the pusher housing, the guidewire axially movable relative to the pusher housing and coil from a first position to a second position, which axial movement pushes the coil and the enlarged member through the distendable aperture and thus uncouple the coil from the pusher housing.
