Abstract

A method for treating a wound of an individual and for enhancing a rate of wound healing by applying, for a first period of time, a negative pressure treatment to the wound without applying a pulsed radio frequency treatment; and applying, for a second period of time subsequent to the first period time, a pulsed radio frequency energy treatment to the wound while maintaining the negative pressure treatment to enhance the rate of wound healing. The negative pressure treatment and the pulsed radio frequency energy treatment are applied concurrently for the duration of the second period of time.

Claims

1. A method for treating a wound of an individual and for enhancing a rate of wound healing, the method comprising:

applying, for a first period of time, a negative pressure treatment to the wound without applying a pulsed radio frequency treatment; and

applying, for a second period of time subsequent to the first period time, a pulsed radio frequency energy treatment to the wound, while maintaining the negative pressure treatment to enhance the rate of wound healing,

wherein the negative pressure treatment and the pulsed radio frequency energy treatment are applied concurrently for the duration of the second period of time.

2. The method of claim 1, wherein the negative pressure treatment is applied continuously throughout the first period of time.

3. The method of claim 1, wherein the negative pressure treatment is applied intermittently throughout the first period of time.

4. The method of claim 1, wherein the negative pressure treatment is applied 24-hours a day throughout the first period of time.

5. The method of claim 1, wherein the negative pressure treatment is applied for less than 24-hours a day throughout the first period of time.

6. The method of claim 1, wherein the enhanced rate of wound healing is greater than a rate of wound healing achieved by the negative pressure treatment alone or the pulsed radio frequency energy treatment alone.

7. The method of claim 1, wherein the second period of time is a period of time sufficient to achieve at least a 90% decrease in wound volume.

8. The method of claim 1, wherein the wound is selected from the group consisting of a chronic wound, a large, deep, open wound, a graft and flap site wound, a full thickness burn, a partial thickness burn, a diabetic ulcer, a pressure ulcers, a decubitus ulcer;

an arterial ulcer;

an avulsion injury a pilonidal disease, a cysts, an acute wound, a tendon rupture wound, a postoperative incision, a postoperative wound, a traumatic wound, a dermatology condition, scleroderma, atrophy blanche disease, trauma, a bomb blast or other military-type inflicted wound, a gunshot wound, a bite, and a wound dehiscence.

9. The method of claim 1, wherein the negative pressure treatment results in an effect selected from the group consisting of:

removing excess interstitial fluid, decreasing bacterial colonization, and stimulating granulation tissue formation.

10. The method of claim 1, wherein the pulsed radio frequency energy treatment results in an effect selected from the group consisting of:

stimulating growth factor production and stimulating cell proliferation.

11. A method for treating a wound of an individual and for enhancing a rate of wound healing, the method comprising:

applying concurrently a negative pressure treatment and a pulsed radio frequency energy treatment, wherein the negative pressure treatment and pulsed radio frequency energy treatment are maintained for a period of time sufficient to achieve the enhanced rate of wound healing,

wherein the enhanced rate of wound healing results in at least a 90% decrease in wound volume.

12. The method of claim 11, wherein the negative pressure treatment is applied continuously.

13. The method of claim 11, wherein the negative pressure treatment is applied intermittently.

14. The method of claim 11, wherein the negative pressure treatment is applied 24-hours a day throughout the period of time.

15. The method of claim 11, wherein the negative pressure treatment is applied for less than 24-hours a day throughout the period of time.

16. The method of claim 11, wherein the enhanced rate of wound healing is greater than a rate of wound healing achieved by the negative pressure treatment alone or the pulsed radio frequency energy treatment alone.

17. The method of claim 11, wherein the wound is selected from the group consisting of a chronic wound, a large, deep, open wound, a graft and flap site wound, a full thickness burn, a partial thickness burn, a diabetic ulcer, a pressure ulcers, a decubitus ulcer;

an arterial ulcer;

an avulsion injury a pilonidal disease, a cysts, an acute wound, a tendon rupture wound, a postoperative incision, a postoperative wound, a traumatic wound, a dermatology condition, scleroderma, atrophy blanche disease, trauma, a bomb blast or other military-type inflicted wound, a gunshot wound, a bite, and a wound dehiscence.

18. The method of claim 11, wherein the negative pressure treatment results in an effect selected from the group consisting of:

removing excess interstitial fluid, decreasing bacterial colonization, and stimulating granulation tissue formation.

19. The method of claim 11, wherein the pulsed radio frequency energy treatment results in an effect selected from the group consisting of:

stimulating growth factor production and stimulating cell proliferation.
