Abstract
According to an embodiment of the present disclosure, a wound dressing system is presented. The wound dressing system includes a fluid permeable support layer, the support layer configured for positioning within a wound and adapted to generally conform to a topography of the wound, and to permit exudates from the wound to pass therethrough. The wound dressing system further includes a plurality of beads supported by the support layer, the beads defining an insulated inter-connected elongate member and an electrode embedded within and extending through at least a portion of the elongate member. Also, a current is generated by an external energy source that electrically flows through the electrode.
Claims11
A method of manufacturing a wound dressing, the method comprising the steps of:
- providing a cover layer, wherein the cover layer is configured for positioning across a wound and is configured to permit exudates from the wound to pass therethrough;
- providing an elongate member positionable in the wound, comprising adjacent beads connected to each other by connecting segments,
- the beads and the connecting segments comprising a hydrogel material;
- and
- providing an electrode extending through at least some of the beads and through the connecting segments along a length of the elongate member;
- wherein a current generated by an energy source electrically flows through the electrode.
