Publication number: 20250049467Abstract: A method of suturing a trocar path incision in a tissue of a patient with an obturator includes inserting the obturator through the tissue such that a shaft of the obturator extends through a tissue opening about the trocar path incision and a distal tip of the obturator is positioned within a cavity of the patient. The method also includes directing the suture via a suturing feature with the obturator inserted through the tissue in order to direct the suture relative to the tissue. Furthermore, the method includes closing the tissue opening about the trocar path incision with the suture.Type: ApplicationFiled: August 16, 2024Publication date: February 13, 2025Inventors: Frederick E.

Patent number: 12203016Abstract: 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.Type: GrantFiled: August 15, 2023Date of Patent: January 21, 2025Assignee: Purple Innovation, LLCInventors: James T.
