Negative pressure wound closure device

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.

The entire content of the above application is hereby incorporated by reference. Background technique [0003] A variety of techniques have been developed to treat wounds, including wounds resulting from accidents and wounds resulting from surgery. Usually sutures or staples are used to close the wound. However, to insert these mechanical closure techniques, an additional puncture or wound must be created in the skin, which can lead to tissue damage and, in the case of overdistension, ischemia and tissue loss. Also, mechanical wound closures such as staples and sutures can create very localized stress at the point of insertion, which can hinder and impair the normal wound healing process of the skin.
