  • Publication number: 20230392047
    Abstract: An article of manufacture, such as a weighted blanket, a cushioning element, or the like, includes an elastomeric element that includes elongated elements that follow nonlinear, partially overlapping paths and voids between adjacent portions of the elongated elements. Such an elastomeric element may define a weighted layer of a weighted blanket, a cushioning layer of a cushioning element of the like. The elastomeric element may be secured directly to a substrate, such as a fabric layer. Alternatively, an adhesion layer may secure the elastomeric element to the substrate. An adhesion layer may cover only a portion of the substrate. A cover may be provided over the elastomeric element. Together, the cover and the substrate may contain the elastomeric element.

  • Patent number: 9585644
    Abstract: A medical system for treating an internal tissue opening can include a closure device and associated delivery device. The closure device can include a body portion operatively associated with a first anchor and a second anchor. The body portion can include a plurality of segments defining a multi-cellular structure. The closure device can be configured to apply lateral force to tissue of the internal tissue opening to bring tissue together. The closure device can have a substantially flat aspect, and have a depth thickness that is substantially greater than the thickness or width of a majority of the members forming the closure device to reduce out of plane bending. The closure device can also include a member adapted to induce tissue growth.
