Abstract

Medical devices, wound dressings, and methods of dressing wounds are described. Devices and methods using silicone and pharmaceutically active agents are described. Devices including covers and bases are described.

Claims

1. A medical device comprising:

a component configured to be coupled to a recipient, the component having at least one surface configured to abut at least one surface of the recipient; and

a tacky silicone layer residing on at least a portion of the one surface of the component, the tacky silicone layer comprising polystyrene sulfonate material distributed therein.

2. The medical device of claim 1 wherein the polystyrene sulfonate material comprises silver polystyrene sulfonate (cross-linked”

and non-cross-linked).

3. The medical device of claim 1 wherein the polystyrene sulfonate material comprises salts of polystyrene sulfonate.

4. The medical device of claim 1 wherein the component comprises wound dressing fabric.

5. The medical device of claim 4 wherein the wound dressing is substantially planar.

6. The medical device of claim 1 wherein the component is configured as a frame having at least one opening within the frame, the tacky silicone layer residing along a perimeter of the frame.

7. The medical device of claim 1 wherein the component is configured to engage at a portion of an epidermis of a patient, the patient being the recipient.

8. The medical device of claim 1 wherein the tacky silicone layer further comprises additional pharmaceutically active agents.

9. The medical device of claim 8 wherein the pharmaceutically active agents include one or more of antimicrobial, anti-inflammatory, and/or antiproteolytic agents.

10. A medical device comprising:

a component configured to be coupled to a recipient, the component having at least one surface configured to abut at least one surface of the recipient; and

a tacky silicone layer residing on at least a portion of the one surface of the component, the tacky silicone layer comprising silver-organo complex material distributed therein.

11. The medical device of claim 10 the silver-organo complex comprise one or more of silver polystyrene sulfonate, crosslinked silver polystyrene sulfonate (IRP69-silver), silver carboxymethylcellulose, and silver polysaccharides.
