Abstract
A wound closure device having a filamentary element having a proximal end and a distal end, and a stop element coupled thereto and having a leading edge area defined by thickness and a width and having a total surface area. The leading edge area is substantially perpendicular to a longitudinal axis of the filamentary element. The device may have a ratio of the leading edge area to the total surface area that is less than 10%, a ratio of the length to the maximum thickness of the stop element that is at least 4, or a ratio of the length to the width of the stop element is at least 1 for any given thickness.
Claims23
A wound closure device comprising:
- a filamentary element having a proximal end and a distal end;
- a stop element coupled to the distal end of the filamentary element, the stop element having a leading edge area defined by thickness and a width, the leading edge area facing substantially perpendicular to a longitudinal axis of the filamentary element, and a total surface area;
- wherein the ratio of the leading edge area to the total surface area is less than 10%.
A wound closure device comprising:
- a filamentary element extending along a longitudinal axis between a proximal end and a distal end;
- a stop element coupled to the distal end of the filamentary element, the stop element having a length extending substantially parallel to the longitudinal axis of the filamentary element, a width extending substantially perpendicular to said longitudinal axis, and a maximum thickness;
- wherein the ratio of the length to the maximum thickness of the stop element is at least 4.
