Surgical cavity drainage and closure system
First Claim
1. A method for treating a wound, the method comprising the steps of:
- positioning a matrix into a surgical wound, the matrix being connected to tissue in the wound with a plurality of tissue anchors extending from a surface of the matrix, wherein the matrix comprises a layer of biodegradable material having a plurality of spaced apart apertures such that tissue on a first side of the matrix contacts tissue on second side of the matrix through the spaced apart apertures in the matrix;
attaching a negative pressure source to a drain device that is in fluid communication with the matrix, the drain device including a plurality of drain tubes extending across tube receiving regions of the matrix the plurality of drain tubes being positioned in the tube receiving regions between spaced apart apertures in the matrix;
draining fluid from the wound for a period of time; and
removing the plurality of drain tubes of the drain device from the wound such that the matrix remains in the wound.

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 and systems containing the device are particularly useful to promote the healing of surgical wounds from abdominal surgery.
