Patent number: 7888304Abstract: The present disclosure is directed to methods and compositions for clearing and cleaning enteral feeding tubes. More particularly, the composition is an ingestible gel composition that comprises enzymes for degrading buildup in enteral feeding tubes, carrageenan, and divalent metal ions or a source thereof. The carrageenan present in the composition stabilizes the enzymes at room temperatures, allowing for long-term storage of the composition. Upon injecting the gelled composition into the feeding tube, body heat from the patient melts the gel, and the enzymes are released to act on debris present in the feeding tube.Type: GrantFiled: July 31, 2007Date of Patent: February 15, 2011Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Sara A.

Publication number: 20110022015Abstract: An article has a body facing engagement surface for contacting a wearer's tissue layer. The body facing engagement surface has a first state adapted to inhibit movement of the article with respect to the tissue layer of the wearer, and a second state adapted to enhance movement of the article with respect to the tissue layer. The body facing engagement surface is adapted to transform from the first state to the second state upon application of a force greater than a threshold force. The body facing engagement surface has a gripping component and a sliding component wherein the gripping component overlies the sliding component in the first state. The gripping component is disposed for engaging and gripping the tissue layer in the first state until a force greater than the threshold force is encountered which transforms the engagement surface to promote relative sliding motion between the engagement surface and the tissue layer.Type: ApplicationFiled: October 7, 2010Publication date: January 27, 2011Applicant: Kimberly-Clark Worldwide, Inc.Inventors: David William Koenig, Wael R.
