Beschreibung
Zusammenfassung:	Systems and methods for occluding a duct and attenuating sound may be provided. In some embodiments, a system may include a toroidal component enclosing an interior volume. The interior volume may contain a fluid and may have an extended state and a retracted state. When the toroidal component is in the extended state, a distal portion of the toroidal component that defines a distal tip is configured to extend in a distal direction and a proximal portion of the toroidal component may define a proximal end of the toroidal component. When the toroidal component is in the retracted state, a portion of the inner surface may extend proximally beyond the proximal end of the toroidal component. A fluid composition and methods for attenuating sound may also be provided. In some embodiments, the fluid composition may be a suspension that includes an interstitial fluid and a plurality of gas-filled spheres.
