    Abstract: The present invention relates to a negative pressure wound closure system and methods for using such a system. Preferred embodiments of the invention facilitate closure of the wound by preferentially contracting to provide for movement of the tissue. Preferred embodiments can utilize tissue grasping elements to apply a wound closing force to the tissue.

    Abstract: A surgical drain device includes an adhesion matrix of biodegradable polymer material and a plurality of drain tubes attached to the matrix. The device is implanted within a surgical wound to treat the presence of seromas, for example, and is used to promote drainage, tissue adhesion, and wound closure. The drain tubes converge into a common collection tube that leads wound fluid outside the body under gravity feed or negative pressure applied to the collection tube. The matrix contains an array of apertures that allow tissue contact across the device. The device also can include a coating of surgical adhesive and a tissue anchoring system of hooks or barbs. The device can be used with a negative pressure system to further improve the drainage band can also be used with a wound dressing. The device and systems containing the device are particularly useful to promote the healing of surgical wounds from abdominal surgery.

    Abstract: Systems, devices, and methods of the present application can accelerate and reduce medical complications associated with healing of non-planar wounds such as amputation wounds. The devices and methods utilize a collapsing structure and negative pressure to cause the shaped wound to preferentially close. The structure can accommodate movement over curved tissue surfaces, which can utilize scales or interleaved elements to provide efficient wound closure along arcuate paths. This structure can enable gradual closure from the deepest portion of the wound to the shallowest portion.
