Abstract

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 the volume of revolution from the surrounding tissue. The severed and captured volume of revolution containing the target issue may then be removed.

First claim

What is claimed is:

1. A device, comprising:
a central tube defining a central axis;
a tube chamber attached to an exterior surface of the central tube, the tube chamber defining an axis of rotation away from the central axis and defining a proximal end and a distal end configured for insertion into tissue; and
a rod element disposed within the tube chamber and configured to rotate about the axis of rotation, comprising a curved and unattached free end portion that is biased a…
