AUTOMATED, SELECTABLE, SOFT TISSUE EXCISION BIOPSY DEVICES AND METHODS

摘要

An excisional biopsy and delivery device may comprise one or more rotating, penetrating and cutting rod elements. The rod elements may be configured to advance from a stored and confined first position and rotate about an axis, while being simultaneously revolved about a central axis. The rod elements may then assume a second released and expanded configuration that is operative to cut around and surround target tissue. In this manner, the rod elements are operative to move through the surrounding tissue to create a volume of revolution and to sever and capture the target tissue contained within fee volume of revolution from fee surrounding tissue. The severed and captured volume of revolution, containing fee target issue may then be removed.
