  • Publication number: 20140058376
    Abstract: The disclosure pertains to an intravascular catheter, comprising an elongate member having a proximal end and a distal end, a balloon having an interior surface, an exterior surface, a lumen defined by the interior surface and a cylindrical wall extending between the interior surface and the exterior surface, the cylindrical wall having a proximal end and a distal end, the balloon having a plurality of weeping windows disposed in the wall and able to pass an electric current between the interior surface and the exterior surface and wherein the balloon wall is otherwise electrically insulative, and an electrode disposed in the balloon. The intravascular system is suited for modulation of renal nerves, for example.

  • Publication number: 20120253193
    Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an elongate inner member having a guidewire lumen extending therethrough. An outer member may be disposed about the inner member. An inflation lumen may be formed between the inner member and the outer member. The medical device may be configured to have a first stiffness when the inflation lumen is free of inflation media and a second stiffness different from the first stiffness when inflation media is disposed within the inflation lumen. In addition, the inner member may include a collapsible region that is configured to deflect radially inward when inflation media is disposed within the inflation lumen.

  • Patent number: 7258673
    Abstract: An interstitial fluid (ISF) extraction device includes a penetration member configured for penetrating a target site of a user's skin layer and, subsequently, residing in the user's skin layer and extracting an ISF sample therefrom and at least three concentrically-arranged pressure rings, each adapted for applying pressure to the user's skin layer in the vicinity of the target site while the penetration member is residing in the user's skin layer. In addition, the ISF extraction device is configured such that (i) the pressure rings apply pressure in an oscillating manner with asymmetric deployment and retraction cycles and (ii) only one of the at least three concentrically-arranged pressure rings is deployed at a time, thereby mitigating an ISF glucose lag of the ISF sample extracted by the penetration member.

  • Publication number: 20060036187
    Abstract: Systems and methods are provided for extracting a bodily fluid sample (e.g., an interstitial fluid sample) and monitoring an analyte therein. Certain of the systems include a a penetration member configured for penetrating and residing in a target site of a user's skin layer and, subsequently, extracting a fluid sample therefrom. The system also includes a pressure ring(s) adapted for applying pressure to the user's skin layer in the vicinity of the target site. The system is configured such that the pressure ring(s) is capable of applying pressure in an oscillating manner. Certain methods include penetrating the skin and applying pressure to the skin in an oscillating manner.

  • Publication number: 20040249253
    Abstract: A system for extracting a bodily fluid sample (e.g., an interstitial fluid [ISF] sample) and monitoring an analyte therein includes a disposable cartridge and a local controller module. The disposable cartridge includes a sampling module adapted to extract a bodily fluid sample and an analysis module adapted to measure an analyte (e.g., glucose) in the bodily fluid sample. The local controller module is in electronic communication with the disposable cartridge and is adapted to receive and store measurement data from the analysis module. An ISF extraction device includes a penetration member configured for penetrating and residing in a target site of a user's skin layer and, subsequently, extracting an ISF sample therefrom. The device also includes a pressure ring(s) adapted for applying pressure to the user's skin layer in the vicinity of the target site.
