Abstract: A system (10) for stimulating the healing of tissue comprises a porous pad (11) positioned within a wound cavity (12), and an airtight dressing (13) secured over the pad, so as to provide an airtight seal to the wound cavity (12). A proximal end (16a) of a conduit (16) is connectable to the dressing (13). A distal end (16b) of the conduit (16) is connectable to a negative pressure source (14), which may be an electric pump housed within a portable housing (32), or wall suction. A canister (18) is positioned along the conduit (16) to retain exudates suctioned from the wound site (12) during the application of negative pressure. A first hydrophobic filter (20) is positioned at an opening of the canister (18) to detect a canister full condition. A second hydrophobic filter (22) is positioned between the first filter (20) and the negative pressure source (14) to prevent contamination of the non-disposable portion of the system by exudates being drawn from the wound. An odor filter (23) is positioned between the first and second hydrophobic filters (20, 22) to aid in the reduction of malodorous vapors. A  securing means (34) is supplied to allow the portable housing (32) to be secured to a stationary object, such as a bed rail or intravenous fluid support pole. A means for automated oscillation of pressure over time is provided to further enhance and stimulate the healing of an open wound. A  means for varying pump drive frequency and a means for managing a portable power supply are provided to increase battery life and improve patient mobility.

Title: Nonbulky ankle brace for use with footwear
Inventor: MCCORMICK SCOTT D
IPC: A61F5/01
Filed: 2003-06-16
Abstract: An ankle brace for comfortably supporting an ankle of a wearer by inhibiting motion between a foot and lower leg of the wearer. The ankle brace employs a laminated, moisture-wicking material for leg and foot portions that improves wearability during athletic activities. The leg and foot portions are combined with medial and lateral stays that are supported within pockets of the leg portion so as to provide medial and lateral stability for the ankle. A  strapping unit is used to further improve stability with a pair of straps that are formed of the same piece of laminate material as the foot portion and extend upwards from the foot portion to cross over the ankle and attach to the leg portion. Advantageously, constructing the straps from the same piece of material as the foot portion eliminates fasteners and overlapping material and allows the ankle brace to be used with off-the-shelf footwear.

Title: Multi-shot injection molded component and method of manufacture
Inventor: JONES DANA MARIE
IPC: B60N2/75
Filed: 2003-06-02
Abstract: An automotive component (10) and a method for manufacturing the same are disclosed. The component (10) comprises a core portion (14) formed of a first material and a second portion (18) integral with the core portion (14) and formed of a second material. In one illustrated embodiment, the first and second materials have different material property characteristics. For example, the first material can be made of a relatively harder plastic material than the second material made of a soft~touch plastic material. The method for manufacturing the component comprises the steps of injecting the first material into a first cavity of a mold to form the core portion (14), altering the mold cavity to form a second cavity and injecting the second material into the second cavity while the first material is in a reactive state to form the second portion (18) of the component. Because the first material is in the reactive state, the second material is integrally formed with the first material.
