Abstract: A negative pressure wound closure devices, systems and methods. Embodiments of the invention facilitate closure of the wound by preferentially contracting under negative pressure to provide for movement of the surrounding tissues. Some embodiments may utilize a stabilizing structure with a plurality of cells configured to collapses more in the x-direction than in the y-direction.

Abstract: The present invention relates to wound closure devices, systems and methods. Embodiments of the invention facilitate closure of the wound by preferentially contracting under negative pressure to provide for movement of the surrounding tissues. Some embodiments may utilize tissue securing portions that aid in securing the invention within a wound.

Abstract: A urinary catheter and method of its use for measuring the internal pressure of a human or other mammal. The catheter includes three lumens, or channels. The first lumen is dedicated to draining urine, the second lumen is dedicated to a retention balloon, and the third lumen is available for connection to a pressure transducer. In use, the catheter is installed in a patient, the third lumen is filled with a pressure transmitting medium, connected to a pressure sensor, and the patient's intra-abdominal pressure is monitored without interruption of the urine flow.

Abstract: A urinary catheter apparatus for measuring the internal pressure of a human or other mammal comprising an elongated urinary catheter having at least two lumen extending longitudinally there-through, at least one channel where the wall is composed of a material being substantially impermeable to liquid, where the interior of the catheter allows the transmission of change of pressure through lumen via a pressure transmitting medium, and pressure sensor means for measuring the pressure of pressure transmitting medium.

Abstract: An improved tonometric catheter can be configured to have one or more pressure transmitting chambers for sensing the internal pressure such as the internal abdominal pressure of a subject. The tonometric catheter is inserted into the patient such as a nasogastric catheter. The pressure sensing chamber in the form of a balloon is insufflated with a pressure transmitting medium when the balloon is in the desired location. After insufflation of the chamber the catheter is connected to a pressure transducer or manometer which then provides an output reading the internal pressure of the subject. The tonometric catheter with a pressure sensing chamber is useful for sensing the internal abdominal pressure such as during laparoscopic surgery. The sensing of internal pressure can also be used at other locations along the gut or in the cranium. The monitoring of internal pressure is also useful in conjunction with the monitoring of internal pH.
