  • Publication number: 20150320406
    Abstract: A sampling catheter encloses a sampling brush which can be selectively extended and retracted from and into the catheter assembly to allow insertion and movement of the catheter while presenting a smooth surface to the body lumen. The selective extension and retraction of the brush allows it to be withdrawn while limiting contamination by contact with tissue outside of the sampled region. The catheter may simultaneously or separately house a cutting tool for slice sampling tissue.
