Abstract: A medical device includes an end effector assembly at a distal end of the medical device. The assembly comprises a pair of jaw members, a pair of electrodes including first and second electrodes, and first and second conductive wires attached to the first and second electrodes, respectively. Each jaw member includes a jaw and a tang, the jaw being transitionable between open and closed configurations for respectively receiving and collecting a tissue portion as a sample. The first and second conductive wires extend to a proximal end of the medical device and are removably connectable to a computing device configured to generate and provide electrical signals to, and determine an impedance measurement of the tissue portion based on response signals received from, the pair of electrodes contacting the tissue portion, and generate and provide a user interface indicating whether to collect the tissue portion based on the impedance measurement.

Abstract: Reconfigurable paint brush containers provide both display packaging and an edging tool. The container has a painting edge aligned with bristles of the paint brush and a fulcrum on which the paint brush rests. The fulcrum initially spaces the bristles of the paint brush away from the painting edge in a resting state. The painting edge is aligned with a wall corner, where paint is to be applied and a force is applied to the paint brush in the direction of the fulcrum. The force overcomes the spacing effect and brings the bristles into contact with the painting edge such that paint on the bristles is applied in a straight line to a portion of the wall exposed to the bristles at the painting edge.
