  • Publication number: 20210045749
    Abstract: In some examples, an embolization device includes multiple sections with three-dimensional non-helical structures when deployed at a vascular site. The multiple sections include a first section and one or more second sections that are smaller than the first section. The first section may have a deployed structure configured to anchor the device at a vascular site (e.g., a blood vessel) of a patient while each of the one or more second sections may be formed from loops that configured to pack and obstruct the vascular site. In some cases, the embolization device also includes a third section having a deployed configuration with multiple helical windings or loops is configured to anchor the embolization device at the vascular site.

  • Publication number: 20190298387
    Abstract: An implant for treatment of a vascular space can form open loops and closed loops in separate cycles to provide balanced stiffness and flexibility. Such an implant provides both stability for retention within the vascular space and conformability for mitigating forces on the vasculature. Such a configuration can also provide proper coverage over an opening to a vascular space into which the implant is delivered, for reducing or eliminating flow into or out of the body cavity and promoting occlusion of the vascular space.

  • Patent number: 9232322
    Abstract: A personal sound processing apparatus has an earphone; a microphone; an electronic sound processor connected between an automatic gain controller (AGC) and a digital volume controller, an automated feedback tracker operatively connected to the microcontroller, and an audio signal amplifier to amplify audio signals which level is controlled by the digital volume controller. The microcontroller is configured to execute electronic instructions for recognizing at least one of a feedback noise condition and a background noise condition in the audio signals and to send a control signal to the digital volume controller to adjust volume level in response to presence of the at least one of the feedback noise condition and the background noise condition.
