20120316417 | GUIDE TUBE FOR AN IMPLANTABLE DEVICE SYSTEM - An apparatus comprising an electrode subsystem configured to interface to biological tissue, an electronic subsystem electrically coupled to the electrode subsystem by a connector, and a guide tube disposed over at least a portion of the electrode subsystem and the connector. The guide tube includes material to provide stiffness to the electrode subsystem and the connector in an axial direction of the guide tube. The guide tube material is removable from the electrode subsystem and the connector over the electronic subsystem when the electrode subsystem is positioned to interface to the biological tissue and while the electronic subsystem remains electrically coupled to the electrode subsystem. | 12-13-2012 |
20120277822 | Current Steering Neurostimulator Device with Unidirectional Current Sources - The present disclosure provides a medical device that includes a neurostimulator. The neurostimulator includes one or more channels. Each channel includes a digitally-controlled switch coupled to a voltage source. The switch is in one of an “on” state and an “off” state in response to a first control signal. Each channel also includes a digitally-controlled current sink coupled to the switch. The current sink is coupled between the switch and the voltage source. The current sink draws a variable amount of electrical current in response to a second control signal. Each channel further includes a conductor coupled to the switch and the current sink. The conductor is configured to be coupled to an electrode that is operable to deliver the electrical current drawn by the current sink to a target tissue area. | 11-01-2012 |
20100217347 | NEUROSTIMULATION FOR THE TREATMENT OF PULMONARY DISORDERS - Uses of a neurostimulator to treat various conditions including asthma, chronic obstructive pulmonary disease (COPD) and allergies is described. A neurostimulator may be used to modulate neural impulses into and out of the target organs, in this case the bronchi and other airway structures. Stimulation can be used to cause airway dilation and also to inhibit airway constriction. | 08-26-2010 |
20100196765 | Reducing DC Resistance In Electrochemical Cells By Increasing Cathode Basis Weight - The use of an increased cathode weight and thickness or basis weight in a primary electrochemical cell for the purpose of reducing DC resistance (Rdc) is described. This is particularly important when the cell is subjected to high rate discharge conditions of the type typically required for medical device applications, such as activating a cardiac defibrillator. A preferred couple is of a lithium/silver vanadium oxide (Li/SVO) cell or a lithium/copper silver vanadium oxide (Li/CSVO) cell. Reducing cell Rdc by increasing basis weight has the added benefit of increasing the cell's energy density through comparatively greater amounts of active cathode material in a give casing volume. | 08-05-2010 |
20100100172 | Stent Coating For Eluting Medication - A vascular stent comprising a drug-eluting outer layer of a porous sputtered columnar metal having each column capped with a biocompatible carbon-containing material is described. This is done by placing the stent over a close-fitting mandrel and rotating the assembly in a sputter flux. The result is a coating that is evenly distributed over the outward-facing side of the stent's wire mesh while preventing the sputtered columnar coating from reaching the inward facing side where a smooth hemocompatible surface is required. The stent is then removed from the mandrel, exposing all surfaces, and finally coated with a layer of carbon such as amorphous carbon or diamond-like carbon. The carbonaceous coating enhances biocompatibility without preventing elutriation of a therapeutic drug provided in the porosity formed between the columnar structures. The result is a stent that is adapted to both the hemodynamic and the immune response requirements of its vascular environment. | 04-22-2010 |
