Patent ID: 8050741

Claim:
A method of delivering an absorbable radiopaque marker to a biopsy site comprising: inserting a cannula having a side port to a biopsy site such that tissue from the biopsy site extends into the side port; advancing a cutter disposed within the cannula through a portion of the tissue extending into the side port to capture a sample of the tissue; removing the cutter and the tissue sample from the cannula; introducing a delivery catheter into the cannula, the delivery catheter configured to deliver an absorbable radiopaque marker through the side port of the cannula to the biopsy site; delivering the absorbable radiopaque marker through a lumen of the delivery catheter and out of the side port of the cannula to the biopsy site, wherein the absorbable radiopaque marker is delivered by hydrating and compressing the absorbable radiopaque marker and injecting the marker by fluid pressure to the biopsy site; and withdrawing the cannula from the biopsy site, leaving the absorbable radiopaque marker at the biopsy site.
