Patent ID: 6984240

Claim:
A vasoocclusion coil for use with a wire having a distal end, said coil having: a proximal end; a coupling member disposed on said proximal end and configured to detachably couple said proximal end to the distal end of the wire; a distal end; a coiled body formed of a multiplicity of windings having a proximal-most winding, a distal-most winding, and main body windings between said proximal-most and distal-most windings, said main body windings having a uniform first diameter, and said proximal-most and distal-most winding a second diameter smaller than said first diameter, wherein said proximal end and said distal end are positioned radially inwardly of said proximal-most and distal-most windings, respectively, and said coiled body acts to occlude a vessel or a cavity when placed within the vessel or cavity; and fibers attached to said windings for facilitating embolization.
