Skin closure device
First Claim
1. A skin closure device for closing a skin wound which defines first and second wound margins separated by a denuded region, said device comprising:
- first and second attachment members;
means for adhesively securing the first and second attachment members to the skin alongside the first and second wound margins, respectively;
means for mechanically securing the first and second attachment members to the skin alongside the first and second wound margins; and
means for interconnecting the first and second attachment members across the wound to adjustably control the separation therebetween through a range of at least 0.5 inches in order to to allow said separation to be reduced gradually and progressively in order to close the denuded region gradually;
said means for adhesively securing and said means for mechanically securing configured such that the attachment members can be adhesively secured to the skin prior to being mechanically secured to the skin.

Abstract
An improved skin closure device is disclosed which includes a pair of attachment members adapted to be positioned along either side of a wound to be closed, wherein the wound is of the type having a denuded region between the marginal edges of the wound. The device includes a plurality of pins associated with the attachment members for the purpose of mechanically securing the attachment members to underlying skin layers, as well as an adhesive interface adapted to adhesively secure the attachment members to the epidermis. A number of interconnecting devices are disclosed which operate to provide a biasing force tending to bring the two attachment members together in order to close the wound gradually and progressively.

8. A method for closing a skin wound which defines first and second wound margins separated by a denuded region, said method comprising:
-
providing a skin closure device comprising first and second attachment members and means for interconnecting the first and second attachment members across the wound to adjustably control the separation therebetween; adhesively securing the first and second attachment members to the skin alongside the first and second wound margins, respectively; mechanically securing the first and second attachment members to the skin alongside the first and second wound margins, respectively; interconnecting the first and second attachment members with the interconnecting means to bias the two attachment members together to tend to close the wound; and
thengradually and progressively shortening the interconnecting means in order to draw the attachment members together gradually over the course of at least several days in order to close the wound gradually. - View Dependent Claims (9, 10, 11, 12, 13)

14. A skin closure device for closing a skin wound which defines first and second wound margins separated by a denuded region, said device comprising:
-
first and second attachment members, both of which define a respective adhesively coated underside and a respective plurality of pin guides, said attachment members shaped to adhesively bond to the skin alongside respective ones of the first and second wound margins, said pin guides shaped to remain outside the skin when the attachment members are adhesively bonded to the skin; a plurality of pins, each slidably disposed in a respective one of the pin guides to engage the skin mechanically in order mechanically to secure the respective attachment member to the skin; and at least one interconnecting member secured between the two attachment members to bias the two attachment members together, said interconnecting member having an effective length which is adjustable through a range of greater than 0.5 inches in order to bias the attachment members together throughout a range of separations as the wound is gradually closed. - View Dependent Claims (15, 16, 17, 18)

19. A skin closure device for closing a skin wound which defines first and second wound margins separated by a denuded region, said device comprising:
-
first and second attachment members; means for adhesively securing the first and second attachment members to the skin alongside the first and second wound margins, respectively; means for mechanically securing the first and second attachment members to the skin alongside the first and second wound margins; and means for interconnecting the first and second attachment members across the wound to adjustably control the separation therebetween through a range of at least 0.5 inches in order to to allow said separation to be reduced gradually and progressively in order to close the denuded region gradually; said interconnecting means comprising; a strap secured to the first attachment member; and means, mounted on the second attachment member, for adjustably securing the strap to the second attachment member at any of a plurality of locations along the strap; said securing means comprising a ratchet adapted to engage the strap and to allow the strap to be moved only to shorten the separation between the two attachment members.
