Abstract
A system for occluding a blood vessel includes an embolization coil having barbed fibers coupled thereto. The coil can be delivered in a straight configuration and then transition into a larger coiled structure. The barbed fibers can overlap within a lumen defined by the larger coiled structure and attached to each other to define a mesh. The barbs of the barbed fiber can limit the fibers from being pulled out of the coil, as well as provide anchoring of the coil to the blood vessel in which the coil is deployed. The barbed fibers can also be used to anchor two coils to each other.
Claims18
A system for occluding a blood vessel, the system comprising:
- a first coil having an elongate shape and defining a plurality of loops and a lumen, wherein the coil has a first configuration that is generally straight;
- a plurality of fibers coupled to the first coil and extending outwardly therefrom;
- and
- a plurality of barbs coupled to the plurality of fibers, wherein the barbs limit the fibers from being pulled out of the coil.
A method for occluding a blood vessel, the method comprising:
- delivering a coil into a blood vessel, wherein the coil includes a plurality of barbed fibers coupled thereto;
- contacting a wall of the blood vessel with the barbed fibers;
- anchoring the barbed fibers to the blood vessel wall;
- and
- occluding the blood vessel with the coil and the barbed fibers.
