Abstract: A print cartridge comprises an ink housing 500 having at least one interior compartment 110 with a print head mounted at the base of the housing in fluid communication with the compartment via a passageway 180 having an entrance above the bottom of the compartment. A compressed foam block 300 substantially fills the compartment above the passageway entrance so as to leave a free space laterally adjacent to the passageway. A rib 198 extends upwardly along one wall of the compartment from the free space partially to the top of the foam block, the foam block not conforming fully to the cross-section of the rib to leave an air vent channel along at least one side of the rib.

Abstract: According to one embodiment, a system for stimulating peripheral nerves in a painful upper chest region of a person's body is provided. The system includes stimulation electrodes adapted to be implanted in tissue proximate a network of peripheral nerve fibers located in and innervating the painful upper chest region and to deliver electrical stimulation pulses to the network of peripheral nerve fibers located in and innervating the painful upper chest region. The system also includes a stimulation source adapted for implantation into the person's body and operable to generate electrical stimulation pulses for transmission to the electrodes for delivery to the network of peripheral nerve fibers located in and innervating the painful upper chest region to relieve pain in the painful upper chest region. The stimulation pulses are specifically tailored to relieve pain in the painful upper chest region.

Abstract: According to one embodiment, a system for stimulating peripheral nerves in a painful region of a person's limb is provided. The system includes stimulation electrodes adapted to be implanted in tissue proximate a network of peripheral nerve fibers located in and innervating the painful region of the person's limb and to deliver electrical stimulation pulses to the network of peripheral nerve fibers located in and innervating the painful region. The system also includes a stimulation source adapted for implantation into the person's body and operable to generate electrical stimulation pulses for transmission to the electrodes for delivery to the network of peripheral nerve fibers located in and innervating the painful region of the person's limb to relieve pain in the painful region. The stimulation pulses are specifically tailored to relieve pain in the painful region. In a more particular embodiment, the painful region is a region of an arm, leg, hand, or foot that has experienced trauma.
