Abstract:
A vasoocclusive device (10) adapted for introduction into a vessel of a human or veterinary patient and capable of occluding a flow in the vessel when introduced into the vessel, comprising:a member (12) having a proximal end (16) and a distal end (18) spaced from the proximal end (16), the distal end (18) of the member (12) being introduced into the vessel before the proximal end (16) of the member (12) is introduced into the vessel; a distal plurality (20) of fibers having an average distal fiber length, the distal plurality (20) of fibers being associated with and extending away from the distal end (18) of the member (12); and a proximal plurality (24) of fibers having an average proximal fiber length, the proximal plurality (24) of fibers being associated with and extending away from the proximal end (16) of the member (12); wherein the average distal fiber length is greater than the length of the member, and the average proximal fiber length is at least twice the average distal fiber length.
