Abstract: An etchant for simultaneously etching NiFe and AlN with approximately equal etch rates that comprises phosphoric acid, acetic acid, nitric acid and deionized water. Alternating layers of NiFe and AlN may be used to form a magnetic core of a fluxgate magnetometer in an integrated circuit. The wet etch provides a good etch rate of the alternating layers with good dimensional control and with a good resulting magnetic core profile. The alternating layers of NiFe and AlN may be encapsulated with a stress relief layer. A resist pattern may be used to define the magnetic core geometry. The overetch time of the wet etch may be controlled so that the magnetic core pattern extends at least 1.5 um beyond the base of the magnetic core post etch. The photo mask used to form the resist pattern may also be used to form a stress relief etch pattern.

Abstract: An apparatus for promoting hemostasis of a puncture formed in a blood vessel accessible through an incision tract and methods of use thereof. The apparatus includes distal and proximal balloons each having a contracted position and an expanded position, the proximal balloon spaced by a predetermined initial distance from the distal balloon. The apparatus further includes at least one catheter coupling the distal and proximal balloons to a source of pressurized fluid to selectively actuate the distal and proximal balloons between the contracted and expanded positions.

Abstract: A hinged anchor for a medical device electrode is disclosed. In one embodiment, the hinged anchor has a hinged portion and an anchor portion. The hinged portion can have a first configuration forming a first angle and a second configuration forming a second angle. The second angle can be a sharper angle than the first angle, and the hinged portion can be predisposed to assume the second configuration. The hinged anchor can be disposed on a control module of a leadless microstimulator device.

Abstract: An apparatus for promoting hemostasis of a puncture formed in a blood vessel accessible through an incision tract. The apparatus includes a distal balloon having a contacted position, in which a profile of the distal balloon is sized for insertion through the blood vessel puncture, an expanded position, in which the distal balloon profile prevents passage through the blood vessel puncture. The apparatus also includes a proximal balloon spaced by a predetermined initial distance from the distal balloon and having a contracted position, in which a profile of the proximal balloon is sized for insertion through the incision tract, and an expanded position, in which the proximal balloon profile blocks passage through the blood vessel puncture. The apparatus further includes at least one catheter coupling the distal and proximal balloons to a source of pressurized fluid to selectively actuate the distal and proximal balloons between the contracted and expanded positions.

Abstract: Enantiomerically pure R-etifoxine and pharmaceutically acceptable salts, solvates, hydrates or prodrugs thereof are provided. Also provided are pharmaceutical compositions comprising the compounds and methods of treating disorders associated with central nervous system using the compounds and pharmaceutical compositions.

Abstract: A method and system for fabricating solid-state energy-storage devices including fabrication films for devices without an anneal step. A film of an energy-storage device is fabricated by depositing a first material layer to a location on a substrate. Energy is supplied directly to the material forming the film. The energy can be in the form of energized ions of a second material. Supplying energy directly to the material and/or the film being deposited assists in controlling the growth and stoichiometry of the film. The method allows for the fabrication of ultrathin films such as electrolyte films and dielectric films.

Abstract: A storable gas inflation/evacuation system and sealing system. The systems are removably connectible to a proximal portion of a guidewire assembly which has an occlusive balloon at a distal portion. The invention includes provision for indicating the presence of oxygen which is undesirable. The storable aspect concerns a sealable container isolating systems components from ambient atmosphere and an oxygen-sensitive material located within the sealable container. The oxygen-sensitive material is initially inactive but activated by exposure to radiation so as to visually change in response to post-radiation oxygen exposure.

For example, some embodiments include a battery deposited directly on the back of a liquid-crystal display (LCD) device.

Abstract: A tether guided bifurcated stent having a generally tubular main body extending along a longitudinal axis connected to a side branch assembly. Both the main stent body and the side branch assembly are capable of forming an unexpanded configuration and an expanded configuration. The bifurcation's expansion is facilitated by a force exerted by the tether. When the side branch assembly is expanded it forms a secondary tubular region defining a generally tubular shape extending at an angle to the longitudinal axis of the main tubular body.

Abstract: Occluded vasculature such as occluded arterial vasculature can be recanalized using a device that is configured to penetrate an occlusion, while limiting a distance that said penetration structure can extend in order to limit inadvertent vascular damage. The device can include an elongate shaft of a guidewire and a stylet disposed within a lumen of the elongate shaft such that the stylet is selectively actuatable within the elongate shaft.

Abstract: An MRAM device comprising an array of MRAM elements, with each element having an MRAM bit influenced by a magnetic field from a current flowing through a conductor, also includes a magnetic keeper formed adjacent the conductor to advantageously alter the magnetic field. The magnetic keeper alters the magnetic field by concentrating the field within the keeper thereby reducing the extent in which fringe field exists, thus allowing the MRAM elements to be formed closer to increase the areal density of the MRAM device. Increase in magnetic field flux due to the magnetic keeper allows operation of the MRAM device with lowered power. Soft magnetic materials such as nickel iron, nickel iron cobalt, or cobalt iron may be used to form the magnetic keeper.

The ventricular assist device is formed of an ventricle body which is anchorable to spaced ventricle wall portions to provide cardiac assistance. Operation of the ventricular assist device is timed or synchronized with the operating phases of the ventricle chamber. The ventricular assist device can be intravascularly deployed to provide a less invasive treatment procedure and can be adapted to provide static support if active assistance is no longer required.
