Abstract
Tools and methods of use for removing biological units from a body surface utilizing a removal tool are disclosed. The tool incorporates a retention member configured to impede movement of the biological unit in the direction of a distal end of the tool and to improve retention of the biological unit in the tool. The retention member is radially movable within the lumen of the biological unit removal tool. The distal tips of the tools are desirably configured to reduce the chance of transection of a biological unit.
