1. A combination of a surgical fastener having a fastener end and a locking cap means for securing the fastener end against tissue, the combination comprising:
- a surgical fastener having a fastener end,a cap body having a through passage adapted to receive said fastener end and allowing for translational movement of the cap body with respect to the fastener end,means associated with said cap body providing at least one locking member which is movable into a clamping position wherein said member temporarily deforms said fastener end to insure positive clamping but which if moved out of the clamping position allows the fastener end to return to its non-deformed condition,and wherein said fastener end is of such material that when tensioned and released it will exert pressure to maintain the locking member in clamping position.

1. A combination of a surgical fastener having a fastener end and a locking cap means for securing the fastener end against tissue, the combination comprising:
-
a surgical fastener having a fastener end, a cap body having a through passage adapted to receive said fastener end and allowing for translational movement of the cap body with respect to the fastener end, means associated with said cap body providing at least one locking member which is movable into a clamping position wherein said member temporarily deforms said fastener end to insure positive clamping but which if moved out of the clamping position allows the fastener end to return to its non-deformed condition, and wherein said fastener end is of such material that when tensioned and released it will exert pressure to maintain the locking member in clamping position. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method for securing tissue after a surgical procedure, wherein a surgical suture is employed having a smooth flexible filament end, comprising the steps of
passing said filament end through said tissue and extending it outwardly thereof; -
mounting a locking cap means upon said filament, said locking cap means having a through hole permitting said locking cap to slide along said filament; sliding said locking cap means along said filament until said means are in contact with the tissue; applying pressure against said locking cap means to firmly seat it against the tissue; thereafter applying tensioning force to said filament while maintaining the pressure upon said locking cap means; and simultaneously actuating clamping elements associated with said locking cap means into filament engaging position, whereby said filament is deformed and said clamping elements are retained in clamping position. - View Dependent Claims (24)

25. A locking cap means for securing the fastener end of a surgical fastener against tissue, comprising:
-
a cap body having a through passage adapted to receive the fastener end and allowing for translational movement of the cap body with respect to the fastener end; means associated with said cap body providing at least one locking member which is movable into a clamping position wherein said member temporarily deforms the fastener end to insure positive clamping but which if moved out the clamping position allows the fastener end to return to its non-deformed condition; the cap body being in the form of a collet comprising a generally flat cylindrical portion having a locking extension protruding outwardly therefrom, the through passage being located to pass through both said cylindrical portion and locking extension; and wherein the locking extension is furcated to form a plurality of locking flaps. - View Dependent Claims (26, 27, 28, 29)

35. A combination of a surgical fastener having a smooth surface flexible filament and a locking cap means mounted on the smooth surface flexible filament for clamping against tissue, the combination comprising:
-
a surgical fastener having a smooth surface flexible filament; a cap body having a hole therethrough for receiving said filament and dimensioned to permit translational movement of the cap body with respect to the filament; means associated with said cap body providing at least one locking member which is movable into a clamping position wherein said member temporarily deforms said filament to insure positive clamping but which if moved out of the clamping position allows the filament to return to its non-deformed condition; and said filament being of such material that when it is tensioned and released it will exert pressure to maintain the locking member in clamping position.

36. A combination of a surgical fastener having a fastener end and a locking cap means for securing the fastener end against tissue, the combination comprising:
-
a surgical fastener having a fastener end; a cap body having a through passage adapted to receive said fastener end and dimensioned to permit translational movement of the cap body with respect to the fastener end; means associated with said cap body providing at least one locking member which is movable into a clamping position wherein said member temporarily deforms said fastener end to insure positive clamping but which if moved out of the clamping position allows the fastener end to return to its non-deformed condition, said locking member being formed of a material denser than the material of said fastener end; and said fastener end being of such material that when it is tensioned and released it will exert pressure to maintain the locking member in clamping position.

37. A combination of a surgical filament having a filament end and a locking cap for securing the filament end against tissue, the combination comprising:
-
a surgical filament having a filament end; a locking cap having a first body and a second body, said first body having a first through passage adapted to receive the filament end to allow translational movement of said first body with respect to the filament end, said first body having at least two locking members mounted proximate said through passage and movable into a clamping position to engage the filament end; and said second body having a second, larger-width through passage slideable over an outer portion of said locking member to force it into said clamping position. - View Dependent Claims (38, 39)

40. A locking cap means for securing the fastener end of a surgical fastener against tissue, comprising:
-
a first body having a first through passage adapted to receive the fastener end to allow translational movement of said first body with respect to the fastener end, said first body having at least tow locking members spaced about a portion of said through passage and movable into a clamping position to engage the fastener end; a second body having a second, larger-width through passage slideable over an outer portion of said locking members to force them into said clamping position; at least one of an outer surface of said locking members and the second passage of said second body being tapered to drive all of said locking members into said clamping position; and at least one of said clamping members including tab means for engaging said second body to secure said second body relative to said first body.
