Abstract: A tampon disposal device includes a tubular stiffener, and a membrane conforming to the stiffener with an opening on one end and an enclosure opposite the opening. The membrane is folded inside the stiffener into a first layer attached to the stiffener; and second and third layers that form a lip surrounding the stiffener near a stiffener rim. The second layer folds over the rim, reversing direction to become the third layer lip portion. The third layer continues inside the stiffener. A weak adhesive attaches the lip to the outside stiffener. Another adhesive attaches the first layer to the second layer inside the stiffener. When a hand grasps a tampon siring with the membrane and pulls on the string, the first adhesive allows the lip to separate and be pulled into the stiffener together with the tampon. Pushing inwardly on the stiffener seals the tampon inside the membrane.

Abstract: An implantable pulse generator that includes a current source/sink generator is disclosed herein. The current source/sink generator includes a current drive differential amplifier. The current driver differential amplifier is configured to selectively source current to, or sink current from a target tissue. The current drive differential amplifier includes an inverting input and a non-inverting input. One of the inputs of the current drive differential amplifier is connected to a virtual ground, and the other is connected to a current command. A stimulation controller can supply a voltage to the other of the inputs of the current drive differential amplifier to select either current sourcing or current sinking.
