摘要： 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.

摘要： 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.

摘要： Devices for treating fistulas may include a cap with a vacuum port, a spacer with a lumen therethrough, a first distal anchor, and a second distal anchor. The devices may be configured to transmit negative pressure through the vacuum port, the spacer lumen, and an opening in the first distal anchor to releasably seal the first and second distal anchors to tissue, thereby securing the devices in place. The first distal anchor may also include a plurality of openings that form vacuum pathways that transmit the negative pressure. The cap may also include a flush lumen, which may allow flushing of a fistula tract without removal of the device. Methods of treating fistulas may include applying negative pressure to a fistula treatment device to anchor the device and flushing a tract of the fistula using a flushing fluid with the fistula treatment device in-situ.

摘要： A healing device for sealing multiple fistulas, large-opening fistulas, and other wounds and for promoting tissue growth is coupled to tissue surrounding a first tissue opening. The healing device includes a first sealing member placed on a first surface of the tissue over the tissue opening. The healing device also includes a second sealing member placed over a second surface of the tissue over the tissue opening. The healing device may include a growth-enhancing layer located between the first sealing member and the second sealing member. The first sealing member and the second sealing member may sandwich the tissue in between to cover the tissue opening and may be held together with a plurality of securing members that do not exert any force on the tissue.

摘要： An implantable device covers and seals an enteroatmospheric fistula or other short-tract opening in tissue and assists in healing the fistula. The implantable device may include a cap that is configured to be positioned on a first side of the tissue and to substantially cover a first opening of the short-tract fistula. The implantable device may also include an anchor member operably connected to the cap. The anchor member may be configured to be positioned on a second side of the tissue and to substantially cover a second opening of the short-tract fistula. Also, the implantable device may include a plug structure operably connected to the cap and the anchor member. The plug structure may be configured to fill the short-tract fistula.
