20090259203CLOSED INCISION NEGATIVE PRESSURE WOUND THERAPY DEVICE AND METHODS OF USE - A surgical tissue therapy device includes a sealant layer and a collection chamber. The sealant layer functions so as to create a sealed enclosure or space between it and the surface of a patient by forming, preferably, an airtight seal around a surgical area of skin trauma. The closed incision tissue therapy device also comprises a collection chamber, which may comprise an elongate tubular chamber with a plurality of longitudinally spaced openings. The collection chamber may be configured to be in fluid communication with the sealant layer and the area of skin trauma and functions as to distribute the negative pressure applied to a surgically closed area of skin trauma. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of air molecules under the sealant layer. The collection material may comprise a material and/or a configuration that permits length changes based upon the length of the corresponding surgical wound or incision.10-15-2009
20100076463IMPLANTABLE FISTULA CLOSURE DEVICE - Disclosed herein is a device for the treatment of a fistula tract having a distal opening and a proximal opening. In one embodiment, the device includes a distal anchor and a proximal anchor. The distal anchor is configured to provide a generally fluid tight seal in the tract in the vicinity of the distal opening and generally prevent proximal displacement of the device within the tract. The proximal anchor is operably coupled to the distal anchor and configured to generally prevent distal displacement of the device within the tract while allowing fluid migration at least one of through and past the proximal anchor when the proximal anchor is deployed in the vicinity of the proximal opening.03-25-2010
20100082056IMPLANTABLE FISTULA CLOSURE DEVICE - Disclosed herein is an implantable device for the treatment of a fistula. In one embodiment, the device includes a distal end, a proximal end and a member near the distal end. The member can be caused to assume a radially expanded state when the device is located in a fistula and caused to transition from the radially expanded state to a radially retracted state, thereby allowing the withdrawal of the device from the fistula.04-01-2010
20100228184Inflatable device for enteric fistula treatment - Disclosed herein is an implantable fistula closure device. The device may include an expandable longitudinally segmented body including a proximal end and a distal end. The segmented body may further include a plurality of porous bodies and a connecting member operably joining together the plurality of porous bodies. The plurality of porous bodies includes a first porous body with a proximal end and a distal end and a second porous body with a proximal end and a distal end, and the connecting member operably connects the proximal end of the first porous body with the distal end of the second porous body.09-09-2010

20090012482DEVICES AND METHODS FOR APPLICATION OF REDUCED PRESSURE THERAPY - Described generally herein are tissue therapy devices, which may comprise a sealant layer and a suction apparatus. The sealant layer functions so as to create a sealed enclosure between it and the surface of a patient by forming, preferably, an airtight seal around an area of tissue that requires negative pressure therapy. The tissue therapy device may comprise a suction apparatus. The suction apparatus is typically in fluid communication with the sealant layer and functions so as to reduce the amount of pressure present underneath the sealant layer. The reduced pressure is self-created by the suction apparatus. Together the sealant layer and the suction apparatus preferably create a closed reduced pressure therapy system. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of the air molecules under the sealant layer.01-08-2009
