Constant width, adjustable grip, staple apparatus and method

An open staple for suturing living tissue comprising:

• (a) a rectilinear bridge part having two ends;
• (b) an S-shaped side part extending downwardly from each end of said rectilinear bridge part, with the upper curved portion of each side part connected to a respective end of said bridge part and facing inwardly while curving outwardly, and the lower-curved portion of each side part facing outwardly and curving inwardly, wherein the upper curved portions are spaced apart from each other by a first distance which is greater than a distance by which the lower curved portions are spaced apart from each other;
• (c) a leg extending from each of said lower curved portions away form said bridge part and perpendicular thereto, said legs being parallel with one another and spaced apart by a distance equal to said first distance;
• such that when an outwardly directed force is applied to each of said lower curved portions, said lower portions become straight, parallel to one another, spaced by a distance equal to said first distance, and perpendicular to said rectilinear bridge part, and said legs turn inwardly and become parallel with said rectilinear bridge part.

A staple, comprising:

• (a) a bridge part having two ends;
• (b) a side part extending downwardly from each end of said bridge part, each side part including a first portion connected to a respective end of said bridge part and extending perpendicular thereto, and a second portion extending from said first portion and curving outwardly therefrom, wherein the first portions are spaced from each other by a first distance which is less than a distance by which the second portions are spaced part from each other;
• and
• (c) a leg extending from each of said second portions away from said bridge part and perpendicular thereto, said legs being parallel with one another and spaced apart by a distance equal to said first distance;
• such that when an inwardly directed force is applied to each said second portion, said second portions became straight, parallel with one another, spaced by a distance equal to said first distance, and perpendicular to said bridge part, and said legs turn inwardly and became parallel with said bridge part.
