Abstract
A marker assembly formed of a carbon fiber composition is disclosed. The marker assembly includes a shaft sized and shaped to be inserted into an organ, wherein the shaft includes a proximal end, a distal end, and a longitudinal axis extending between the proximal end and the distal end. The distal end of the shaft is sized and shaped to be positioned near a target region within the organ, and the shaft includes a lumen extending through the shaft in a direction parallel to the longitudinal axis of the shaft. The lumen is constructed to accommodate a needle therethrough, so that the needle enters through the proximal end of the shaft, extends through the shaft, and exits through the distal end of the shaft. The marker assembly can also include other radiopaque or semi-radiopaque materials that provide higher definition imaging than titanium, when implanted within the organ.
