In one embodiment, the present invention relates to a method of treating a wound, involving applying to the wound a room temperature vulcanizing silicone composition comprising a crosslinkable polymer, a crosslinking agent, and a catalyst; permitting the room temperature vulcanizing silicon composition to cure thereby forming a membrane having a thickness from about 0.1 mm to about 5 mm; and removing the membrane from the wound after at least about 1 day.

The present invention relates to treating skin wounds, especially those resulting from surgery, by applying a specifically defined silicone composition over the wounds.
Skin wounds, whether caused by injury or surgery, raise several concerns. One concern is scarring. Scarring in many instances results in a diminished sense of touch, weak regions in the skin (where scars join unwounded skin), and obvious cosmetic problems. Scarring is presently associated with injury and surgical wounds. It is therefore desirable to minimize scarring.
Another concern is infection or contamination. This is because an exposed wound is an ideal breeding ground for harmful bacteria. Even with conventional dressings, infections are fairly common. It is therefore desirable to minimize infections.
The present invention generally provides treatments for surgical wounds. In one embodiment, the present invention provides a method of facilitating healing of surgical wounds. In another embodiment, the present invention provides a method of preventing infection of surgical wounds. In yet another embodiment, the present invention provides a method of minimizing scarring due to surgical procedures. In a specific embodiment, the present invention provides a method of facilitating healing of surgical wounds caused by laser surgery.
The present invention involves using a room temperature vulcanizing (RTV) silicone composition to cover surgical wounds, especially wounds from laser surgery, to facilitate at least one of wound healing, infection prevention, and scarring minimization. The RTV silicone composition is preferably an addition cured RTV silicone composition, although a condensation cured RTV silicone composition may be employed. In one embodiment, the RTV silicone composition is a two-part RTV silicone composition. In another embodiment, the RTV silicone composition is an RTV silicone elastomer.
The RTV silicone composition contains at least three components; namely; a crosslinkable polysiloxane, a crosslinking agent, and a catalyst. In many embodiments, the RTV silicone composition further contains at least one optional additives including fillers and medicaments. In embodiments where the RTV silicone composition is a two-part RTV silicone composition, one part contains the crosslinking agent while a second part contains the catalyst. Typically both parts contain the crosslinkable polysiloxane, and one or both parts may contain at least one optional additive.
