Abstract
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.
Claims20
Thrombogenic apparatus comprising
- a catheter for threading into a body vasculature passageway to a target location, and
- a resilient wire means 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, said wire means formed into a coil and including a plurality of cuts on the exterior surface thereof at selected locations, to increase the flexibility of the wire means.
A thrombogenic apparatus comprising
- a catheter for threading into a body vasculature passageway to a target location, and
- a resilient, tubular wire having sidewalls surrounding a central hollow 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, said resilient, tubular wire including a plurality of cuts on the exterior surface thereof at selected locations, to increase the flexibility of said wire.
Thrombogenic apparatus comprising
- a catheter for threading into a body vasculature passageway to a target location, and
- a resilient wire coiled and shaped to occupy a certain volume when unconstrained, and to straighten when inserted lengthwise into and constrained by the catheter, for discharge therefrom to expand and occupy the target location, said wire formed to have a coil diameter which becomes gradually smaller toward a distal end and having a plurality of cuts on an exterior surface thereof.
