Abstract
A percutaneous access system is disclosed that includes a needle and an inner cannula. The needle includes an internal passageway. At a distal end, the needle includes an expandable section. A distal section of the internal passageway of the needle, which corresponds to the expandable section, is tapered to enable the expandable section to expand and collapse as the inner cannula is positioned within and/or moves through the tapered distal section. The inner cannula may enable grasping and/or aspiration of a sample from a location of interest within a subject's body. Biopsy methods are also disclosed.
