Embodiments disclosed herein are directed to negative pressure treatment systems and wound dressing systems, apparatuses, and methods that may be used for the treatment of wounds. In particular, some embodiments are directed to improved wound dressings comprising a bridge portion connecting two or more portions of an absorbent layer that facilitates trimming of the wound dressing to suitable sizes. Some embodiments provide for trimming the dressing in a gap between two or more portions of an absorbent layer and sealing the exposed portion of dressing after trimming when the dressing is applied to skin surrounding a wound.

Certain embodiments described herein are directed to an elongated layer of material and a lip to be placed in contact with a wound and the elongated layer of material to be wrapped around a wound filler, their methods of use and systems incorporating the same, wherein the wound filler lip is configured to be positioned beneath the fascia. Additionally, some embodiments described herein are directed to the closure of the wound and the use of attachment mechanisms on the elongate layer and lip to attach to the wound surface.

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.

A dressing for treating a tissue site with negative pressure may include a first layer having a first side, a second side, and fenestrations having a raised edge extending from the first side. The raised edge is configured to expand in response to a pressure gradient across the first layer. The dressing also includes a second layer adjacent to the first side. The second layer includes a manifold. The dressing also includes a cover coupled to the second layer opposite the first layer. The cover includes a polymer drape.

A dressing interface includes a base that has an aperture and a plurality of microneedles that are attached to the base and disposed over the aperture. The interface also includes a port that is configured to receive a fluid conductor and a conduit that couples the port and the aperture. Each of the microneedles contains a passageway that is fluidly coupled to the aperture. The interface may be used with a drape that is placed over a tissue site. The interface may provide communication between the tissue site and a reduced-pressure source through the microneedles piercing the drape rather than by cutting a hole in the drape.

A system for providing instillation fluid to a deep abdominal wound includes an instillation module and a connection structure. The instillation module defines a first surface and a second, abdominal contents-facing surface. The instillation module includes a distribution hub configured to receive instillation fluid from an instillation fluid source. The connection structure includes a first surface, a second, abdominal contents-facing surface; and a flow path extending between the first surface and the second surface. The flow path includes an inlet configured to receive an instillation fluid conduit engaged with the instillation fluid source and an outlet in fluid communication with the instillation module. The flow path defines an axis extending between the inlet and the outlet. The flow path is configured to compress in a direction defined by the axis.

A dressing assembly for use with a reduced pressure treatment system, the dressing assembly develops a directed force under reduced pressure. The directed force may be a radial force or a closing force. The dressing assembly includes a shaped dressing bolster having a shaped extremity that is operable to evenly deliver the radial force and to distribute reduced pressure. Numerous shapes may be used for the shaped extremity. The dressing assembly may further include an over-drape to assist in creating a seal over the shaped dressing bolster and against a portion of a patient's epidermis.

A reduced-pressure system for treating tissue, such as damaged subcutaneous tissue, includes a shaped dressing bolster for placing on the patient's epidermis and substantially sized to overlay the damaged subcutaneous tissue. The system further includes a sealing subsystem for providing a fluid seal over the shaped dressing bolster and a portion of the patient's epidermis, and a reduced-pressure subsystem for delivering a reduced pressure to the sealing subsystem. The reduced-pressure system may develop a force, which may include a vertical force that is realized at tissue site deeper than the epidermis or a closing force directed towards the incision. The shaped dressing bolster is shaped to evenly distribute the force. Other methods and systems are included.

A suction stent for introduction into a hollow organ of the human or animal body, preferably into the gastrointestinal tract, in particular the intestine, includes a tubular hollow body which is open in the longitudinal direction and made of biocompatible material. The tubular hollow body has a fixed diameter at least in its central portion; and a porous shapeable material, preferably a sponge material, which is biocompatible and shapeable in the radial direction, the porous shapeable material radially sheathing the tubular hollow body at least in a section of the tubular hollow body. Further, a method is provided for sealing a leakage, especially an anastomosis, of the hollow organ.

A negative pressure drainage and cleaning system for sutureless closed skin incision. The system comprises: irrigation device, which comprises a delivery pump and a first catheter partially probing into inner cavity of a subcutaneous incision at a preset depth and is used for delivering irrigation solution; a negative pressure device, which comprises a negative pressure source and a second catheter partially probing into the inner cavity of a subcutaneous incision at a preset depth; a control device, electrically connected to the irrigation device and the negative pressure device. The system can assist to implement the sutureless closure of a full-thickness tissue above the deep fascia of the skin, avoids horizontal scars on the skin surface caused by suture compression/cutting, and leaves no suture knots in the superficial fascia, thereby eliminating an important factor which causes colonization of bacteria and a main cause of recurrence of wound infection.
