Catheter deliverable thrombogenic apparatus

摘要

A catheter deliverable thrombogenic device includes a catheter for threading into a body vasculature passageway to a target location, and a resilient wire element coiled and shaped to occupy a certain volume when unconstrained, and to straighten when inserted lengthwise into and constrained by the catheter, for ultimate discharge therefrom to expand and occupy the target location. The wire element includes a plurality of cuts on the exterior surface thereof at selected locations to increase the flexibility of the wire element.
