  • Publication number: 20250049424
    Abstract: A medical device comprising a handle comprising a first actuator coupled to a first set of articulation cables; and a second actuator coupled. The device may include a shaft comprising a distal articulation section configured to bend with a distal articulation deflection angle and a distal articulation radius, wherein actuation of the first articulation member is configured to induce the distal articulation deflection angle in the distal articulation section. The device may further include a balloon configurable in a deflated state and an inflated state.

  • Publication number: 20240374247
    Abstract: An embodiment of a tissue engagement device having a sheath, a first arm, a second arm, a first tissue engaging member, a second tissue engaging member, and an actuation cannula. At least a proximal portion of each arm is within the sheath and the tissue engaging members may be positioned on a distal end of each arm. The actuation cannula is also within the sheath, and can move within the sheath between a retracted position and an extended position. The actuation cannula moves at least a portion of each of the first and second arms into a region between an exterior surface of the actuation cannula and an interior surface of the sheath as the actuation cannula moves to the extended position. The engaging members are configured to pierce a desired tissue and anchor to the desired tissue layer when the actuation cannula is in the extended position.

  • Publication number: 20070195975
    Abstract: A gain reduction meter for dynamics processing provides information describing which part of a dynamics curve is affecting the input signal. In particular, the gain reduction meter displays an amount of gain reduction due to applying a dynamics processing operation in a manner that differentiates between gain reduction achieved by the different parts of the dynamics curve for that dynamics processing operation. The gain reduction meter has a plurality of display elements. Each display element corresponds to an amount of gain reduction. The illumination of the display elements is controlled such that the appearance of each illuminated display element is dependent on where on the dynamics curve the amount of gain reduction corresponding to that display element is produced.
