Abstract
Abstract A method and a device for holding together a pair of tissue edges defining a wound in a skin layer of a patient, the skin layer having an epidermic top layer and an underlying dermic layer. The device includes a first locking element, a second locking element, a locking structure positioned on either one of the first or second locking element for locking the first locking element to the second locking element. A first grasping structure is positioned on the first locking element for grasping on a portion of the dermic layer positioned adjacent the first locking element. A second grasping structure is positioned on the second locking element for grasping on a portion of the dermic layer positioned adjacent the second locking element. The first and second locking elements are adapted to be inserted by a puncturing action, on each side of the wound, through the epidermic layer and into the dermic layer, so that the first and second locking elements are completely embedded into the dermic layer of the skin. The first and second locking elements are then adapted to be pushed towards one another until the locking structure locks them together adjacent the tissue edges with the first and second grasping structure respectively grasping onto the portion of the dermic layer positioned adjacent the first locking element and the portion of the dermic layer positioned adjacent the second locking element, the first and second locking element thus closing the wound while being embedded into the dermic layer of said skin. The first and second locking elements are made of bioabsorbable material. Since the operation is effected by a puncturing action into the dermic layer, scarring is reduced to a minimum.

Claim 1
Independent Claim
268 words
A device for holding together a pair of tissue edges defining a wound in a skin layer of a patient, said skin layer having an epidermic top layer and an underlying dermic layer, said device being adapted to be puncturingly inserted through both said epidermic top layer and said underlying dermic layer said device comprising: a first substantially elongated locking element; a second substantially elongated locking element; an interlocking means positioned on one of said locking elements for interlocking said first locking element and said second locking element; a first grasping means positioned on said first locking element for grasping on a portion of said dermic layer positioned adjacent said first locking element; a second grasping means positioned on said second locking element for grasping on a portion of said dermic layer positioned adjacent said second locking element; whereby, said first and second locking elements are adapted to be inserted by a puncturing action, on each side of said wound, through said epidermic layer and into said dermic layer, so that said first and second locking elements are embedded into said dermic layer of said skin, and whereby said first and second locking elements are adapted to be pushed towards one another until said locking means locks them together adjacent said tissue edges with said first and second grasping means respectively grasping onto said portion of said dermic layer positioned adjacent said first locking element and said portion of said dermic layer positioned adjacent said second locking element, said first and second locking element thus closing said wound while being embedded into said dermic layer of said skin.
Claim 2
Independent Claim
268 words
A device for holding together a pair of tissue edges defining a wound in a skin layer of a patient, said skin layer having an epidermic top layer and an underlying dermic layer, said device being adapted to be puncturingly inserted through both said epidermic top layer and said underlying dermic layer said device comprising: a first substantially elongated locking element; a second substantially elongated locking element; an interlocking means positioned on one of said locking elements for interlocking said first locking element and said second locking element; a first grasping means positioned on said first locking element for grasping on a portion of said dermic layer positioned adjacent said first locking element; a second grasping means positioned on said second locking element for grasping on a portion of said dermic layer positioned adjacent said second locking element; whereby, said first and second locking elements are adapted to be inserted by a puncturing action, on each side of said wound, through said epidermic layer and into said dermic layer, so that said first and second locking elements are embedded into said dermic layer of said skin, and whereby said first and second locking elements are adapted to be pushed towards one another until said locking means locks them together adjacent said tissue edges with said first and second grasping means respectively grasping onto said portion of said dermic layer positioned adjacent said first locking element and said portion of said dermic layer positioned adjacent said second locking element, said first and second locking element thus closing said wound while being embedded into said dermic layer of said skin.
Claim 3
Dependent Claim
77 words
A device as recited in claim 1 wherein, said first locking element has a channel extending longitudinally therethrough, said channel has a channel diameter, said second locking element has a second element cylindrical body, said second element cylindrical body has an external diameter smaller then said channel diameter, whereby said second element cylindrical body is adapted to be at least partially inserted into said channel when said locking means locks said first and second locking elements together.
Claim 4
Dependent Claim
70 words
A device as recited in claim 2 wherein said locking means comprises a plurality of internal peripheral locking rims extending radially and inwardly from said channel of said first locking element, a corresponding plurality of external peripheral locking recesses positioned on the outer periphery of said second element cylindrical body, whereby said locking recesses are adapted to receive said locking rims for locking said first and second locking elements together.
Claim 5
Dependent Claim
80 words
A device as recited in claim 2 wherein said locking means comprises a plurality of second element peripheral locking rims extending radially and outwardly from the outer periphery of said second element cylindrical body, a corresponding plurality of first element internal peripheral locking recesses positioned on the inner periphery of said channel of said first locking element, whereby said first elementlocking recesses are adapted to receive said second element locking rims for locking said first and second locking elements together.
Claim 6
Dependent Claim
77 words
A device as recited in claim 2 wherein said first and second locking elements have a front end and a back end, said first grasping means comprises an external peripheral first grasping flange extending substantially outwardly from said cylindrical body of said first locking element adjacent its back end, and said second grasping means comprises an external peripheral second grasping flange extending substantially outwardly from said cylindrical body of said second locking element adjacent its back end.
