Patent application numberDescriptionPublished
20110144717Implantable neurostimulation system and methods of using the system for appetite control and pain control - An implantable electronic device includes a geodesic shaped dome housing and means for attaching the dome to a target neurologic structure. The dome includes a radio frequency receiver, an amplifier, and a stimulating electrode. A radio frequency based neurostimulatory system further includes a transmitting coil positioned outside a patient's body for transmitting pulses to the receiver and activating the stimulating electrode within the implantable electronic device. A method of stimulating a patient's neurologic structure includes implanting an electronic device proximate the neurologic structure, positioning a transmitting coil outside the patient's body for controlling the implantable device, initiating radio frequency waves from a pulse generator to the transmitting coil which in turn activates the stimulating electrode. The neurostimulatory system can be used for relief of visceral and somatic pain as well as for controlling appetite in patients.06-16-2011

20110124957APPARATUS AND METHOD FOR INSERTING AN ADJUSTABLE IMPLANTABLE GENITOURINARY DEVICE - An implantable medical device and method for adjustably restricting a selected body lumen such as a urethra or ureter of a patient to treat urinary incontinence or ureteral reflux. The device includes an adjustable element and a tubular elongate body, where the adjustable element includes a chamber and the tubular elongate body includes at least a first interior passageway which extends longitudinally in the tubular elongate body from a first opening at the proximal end to a second opening in fluid communication with the chamber. Fluid volume passed through the first passageway is used for adjustably expanding or contracting the adjustable element. The implantable medical device further includes a sheath and a sleeve, where the sheath includes a wall having an inner surface which defines a channel through which at least a portion of the implantable device and the sleeve can pass. Alternatively, the implantable medical device includes a tip suitable to penetrate tissue so that the implantable medical device can be implanted within the tissue of a patient.05-26-2011

20080279960Silver-Containing Antimicrobial Articles and Methods of Manufacture - A silver composition comprising silver sulfate, methods of making antimicrobial articles, particularly packaged antimicrobial articles, methods of whitening antimicrobial articles, and packaged antimicrobial articles.11-13-2008
20080299600Apparatus Assembly and Method for Detecting an Analyte - An apparatus assembly for detecting an analyte in a sample of material includes a generally self-contained housing and an indicator cap. The housing is moveable between a sample preparation orientation and a testing orientation and is configured to interchangeably receive a sample collection device and the indicator cap having a testing device for detecting the analyte.12-04-2008
20090019953Apparatus And Method For Detecting An Analyte - An apparatus for detecting an analyte in a sample of material includes a chamber for receiving an eluted sample of material from a sample acquisition device and a testing device adapted to detect the analyte.

20100030179ABSORBENT MEDICAL ARTICLES - Medical articles including an absorbent layer, a backing layer and an optional liquid permeable facing layer are disclosed. The construction of the medical article is such that volumetric expansion of the absorbent layer is allowed in directions parallel to the surface of the backing layer as the absorbent layer absorbs moisture. The medical article may include a debonding agent located between the absorbent layer and the backing layer. The absorbent layer is operably attached to the backing layer. When the absorbent layer absorbs moisture, e.g., wound exudate, at least a portion of the absorbent layer detaches from the backing layer such that the absorbent layer can expand and move relative to the backing. The debonding agent facilitates this change from attachment to detachment of the absorbent layer to the backing. The medical articles of the present invention may also be constructed such that a portion of the front surface of the backing layer located directly opposite the absorbent layer is free of adhesive. The adhesive free area or areas may be provided in place of a physical debonding agent or in addition to a physical debonding agent.02-04-2010
