Abstract
Official abstract text for this publication.
This invention relates to the design of tissue covering elements for use in vacuum assisted tissue apposition systems, wherein the geometry of the covering elements favors the application of contractile forces over compressive or extensive forces at the tissue interface.
First claim
Opening claim text (preview).
What is claimed is: 1. A tissue stabilizing element for use in a vacuum assisted closure system, the tissue stabilizing element comprising: a bridging portion comprising a plurality of flat, internal surfaces, the bridging portion configured to be positioned relative to a wound; a vacuum connection aperture, the vacuum connection aperture disposed on the bridging portion; wherein the bridging portion is configured to contract to a greater extent along a first direction relative to a second direction upon application of negative pressure, the first direction parallel to the wound and the second direction perpendicular to the wound; wherein the flat, internal surfaces comprise faces, the faces configured to collapse toward one another upon application of negative pressure; and wherein the bridging portion is configured to apply a closing force to the wound along the first direction. 2. The tissue stabilizing element of claim 1 , wherein the bridging portion is configured for placement over the wound. 3. The tissue stabilizing element of claim 1 , wherein the bridging portion is chamfered. 4. The tissue stabilizing element of claim 1 , wherein the bridging portion is corrugated. 5. The tissue stabilizing element of claim 1 , wherein the bridging portion comprises a plurality of angles between the internal surfaces, the angles configured to decrease upon application of negative pressure. 6. The tissue stabilizing element of claim 1 , wherein the bridging portion further comprises a plurality of hinges between the internal surfaces. 7. The tissue stabilizing element of claim 1 , wherein the bridging portion is transparent.
