Abstract
A medical implant may include a structural member and a radiopaque marker. The structural member may include a first surface, a second surface disposed opposite the first surface, an opening extending from the first surface to the second surface and defining a central axis, and a plurality of barbs extending into the opening toward the central axis. The barbs may be spaced apart from one another and spaced apart from each of the first surface and the second surface. The radiopaque marker may be disposed within the opening.
Claims20
A medical implant comprising:
- a structural member comprising:
- a first surface;
- a second surface disposed opposite the first surface;
- an opening extending from the first surface to the second surface and defining a central axis of the opening, wherein the opening is defined by a first curved surface and a second curved surface, wherein the first curved surface and the second curved surface are cylindrical surfaces or frustoconical surfaces, and wherein the first curved surface and the second curved surface define respective central axes that are coaxial with the central axis of the opening;
- and
- a plurality of barbs extending into the opening toward the central axis of the opening;
- and
- a radiopaque marker disposed within the opening.
A medical implant comprising:
- a structural member comprising:
- a first surface;
- a second surface disposed opposite the first surface;
- an opening extending from the first surface to the second surface and defining a central axis, wherein the opening is defined by:
- a curved surface extending from the first surface to the second surface;
- and
- a planar surface extending from the first surface to the second surface;
- and
- a barb disposed on the planar surface and extending into the opening toward the central axis;
- and
- a radiopaque marker disposed within the opening.
A medical implant comprising:
- a structural member comprising:
- a first surface;
- a second surface disposed opposite the first surface;
- an opening extending from the first surface to the second surface and defining a central axis;
- and
- a barb extending into the opening toward the central axis, wherein the barb comprises:
- a first end;
- a second end disposed opposite the first end in a direction from the first surface toward the second surface;
- a first radially inner surface disposed between the first end and the second end and angled relative to the central axis in a first orientation, wherein the first radially inner surface and the central axis define a first acute angle therebetween;
- a second radially inner surface disposed between the first end and the second end and angled relative to the central axis in a second orientation opposite the first orientation, wherein the second radially inner surface and the central axis define a second acute angle therebetween;
- a first end surface disposed at the first end and extending transverse to the central axis;
- and
- a second end surface disposed at the second end and extending transverse to the central axis.
