Abstract
Abstract A non-invasive closure functions to draw together and close the open edges of a wound while retaining such edges in an approximated and everted condition during the healing process. The closure comprises a pair of base plates having inner and outer edges as well as structure for securing these plates along opposite sides of a wound with the inner edges thereof parallel to one another and in close proximity to the wound. One of a pair of operator elements is connected at its inner end to one of the base plates at the inner edge thereof and the other element is similarly connected to the other base plate. Each operator element extends upwardly and outwardly away from its respective base plate at an angle greater than 90° so that the operator elements are angled toward one another before the wound is closed. Cooperative fastening structure on the operator elements functions to hold them in generally parallel mutually engaging relationship when the elements are urged together to close the wound. Such urging causes the inner edges of the base plate to shift toward one another to thereby close the wound and also to move in an outward direction to thereby evert the edges of the wound.

Claim 1
Independent Claim
212 words
A sutureless closure for drawing together and closing the open edges of a wound while retaining such edges in an approximated and everted condition during the healing process, the closure comprising a pair of base plates each having inner and outer edge portions, means for securing the base plates along opposite side of a wound with the inner edge portions thereof generally parallel to one another and in close proximity to the wound, a pair of operator elements each having inner and outer ends, one operator element connected at its inner end to one of the base plates at the inner edge portion thereof and the other element similarly connected to the other base plate, each operator element extending upwardly and outwardly away from its respective base plate at an angle greater than 90° whereby the operator elements are angled toward one another before the wound is closed, and fastening structure for holding the operator elements in generally parallel mutually engaging relationship with one another when the elements are urged together to close the wound, such urging causing the inner edge portions of the base plates to shift toward one another to thereby close the wound and also to move in an outward direction to thereby evert the edges of the wound.

Claim 7
Dependent Claim
23 words
A sutureless closure as in claim 1 wherein the means securing the base plates on opposite sides of a wound comprises adhesive material.
Claim 8
Dependent Claim
19 words
A sutureless closure as in claim 1 wherein the base plates and operator elements are fabricated of thermoplastic material.
Claim 9
Dependent Claim
30 words
