Abstract
An implantable prosthesis can comprise a strut having a lumen, radiopaque particles within the lumen, and a polymer binder. The polymer binder retains the radiopaque particles within the lumen. The strut may have side holes through which a therapeutic agent may pass and through which the radiopaque particles are incapable of passing. The polymer binder may be absent or optional. The radiopaque particles can have sizes that prevent them from escaping out of the lumen through the side holes. The radiopaque particles placed within the lumen can improve visualization of the prosthesis during an implantation procedure.
Claims19
A method of making an implantable prosthesis, the method comprising:
- placing radiopaque particles within a lumen of a strut having a plurality of side holes extending from the lumen to an exterior surface of the strut, the radiopaque particles having sizes that prevent the radiopaque particles from passing through the side holes,
- wherein placing the radiopaque particles within the lumen includes placing some of the radiopaque particles directly below the side holes.
A method of making an implantable prosthesis, the method comprising:
- placing radiopaque particles within a lumen of a strut having a plurality of side holes extending from the lumen to an exterior surface of the strut, the radiopaque particles having sizes that prevent the radiopaque particles from passing through the side holes,
- wherein the placing of the radiopaque particles within the lumen includes introducing the radiopaque particles through an end hole of the strut.
