Abstract: An electrode lead includes an elongate lead body and a nerve cuff. The nerve cuff may include a cuff body, with a front layer and a rear layer, affixed to the distal end of the lead body and a plurality of electrically conductive members located between the front and rear layers. Each of the electrically conductive member defines a front side, a rear side and an outer perimeter and may include a plurality of holes that extend from the front side to the rear side and that are located around the outer perimeter. The cuff body front layer includes a plurality of windows that are respectively aligned with and located inwardly of the outer perimeters of the electrically conductive members, and a plurality of window frames that extend from the windows to the outer perimeters of the electrically conductive members. The cuff body also includes a plurality of anchors that respectively extend through the electrically conductive member holes and connect the window frames to the cuff body rear layer.

Abstract: An electrode that includes an elongate lead body and a nerve cuff. The nerve cuff may include a biologically compatible, elastic, electrically insulative helical cuff body configured to be disposed around a nerve, and a plurality of electrically conductive contacts carried by the helical cuff body that are spaced from one another.

Abstract: A method of forming a nerve cuff by combining a plurality of electrically conductive members with respective rear surfaces and grit blasted front surfaces with a nerve cuff body, which includes a respective plurality of windows, in such a manner that exposed portions of the grit blasted front surfaces are within the windows.

Abstract: An electrode that includes an elongate lead body and a nerve cuff. The nerve cuff may include a biologically compatible, elastic, electrically insulative cuff body configured to be circumferentially disposed around a nerve, first and second relatively wide electrically conductive contacts carried by the cuff body that are spaced from one another in the length direction and that extend in the width direction to such an extent that they extend completely around the cuff body inner lumen when the cuff body is in the pre-set furled shape, and a plurality of relatively narrow electrically conductive contacts carried by the cuff body that are spaced from one another in the width direction and are located between the first and second relatively wide electrically conductive contacts.

Abstract: In various embodiments, a drug pump includes a housing and, within the housing, an expandable drug reservoir at least part of which is exposed to a pressurized propellant. The propellant exerts a substantially constant pressure on the drug reservoir. A flow restrictor significantly limits outflow from the pump, and preferably has both a small diameter and a long path length, which acts to control the outflow from the drug reservoir. As a result, the pump produces a substantially constant outflow.

Abstract: Embodiments of the present invention provide a vent arrangement integrated with a refill port disposed on the outer shell of an implantable drug-delivery device. The vent arrangement may utilize a tiered structure with two septums in a space-efficient configuration that facilitates both venting of pressure and refill of the drug reservoir.

Abstract: Refill needles include a refill lumen for refilling a drug reservoir with a liquid and a venting channel for venting the device to be refilled. In various embodiments, the termini of the refill lumen and the venting channel are longitudinally displaced along the needle.

Abstract: In various embodiments, a system for receiving wireless power includes a magnetic core and a plurality of layers of unbraided electrical conductors wrapped around the magnetic core. Each unbraided electrical conductor includes a first endpoint and a second endpoint; the first endpoint and the second endpoint are electrically connected to a circuit to provide power thereto, and two of the unbraided electrical conductors are electrically insulated from each other between the first endpoint and the second endpoint. The system may include a biocompatible, magnetically transparent, rigid polymer casing surrounding the magnetic core and at least a portion of the electrical conductors.

Abstract: The invention is a pump cap that is designed to seat on top of a receptacle, which in at least one example is filled with powder or hair fibers. The cap is fitted on top with a deformable dome with an empty chamber of air within it. The cap has an air inlet with a check valve that then opens into a wide flared opening into the dome's empty chamber. The air in the dome is pushed past a check valve and down a long passageway into the receptacle to aggressively disturb the powder or hair fibers within the receptacle. The disturbed hair fibers or powder then exits the cap through a third passage with a flared opening that is flush with the bottom of the cap that then exits out the side of the cap.

Abstract: The present invention relates to a pumping device for dispensing a media. More specifically the present invention relates to a pump dispenser consisting of a pump cap and a receptacle, said pump cap being particular suitable for dispensing powder or fiber.
