Surgical staple and stapler device therefor

Claim 2

A surgical staple, comprising: a base having first and second base segments defining in an un-deformed state a substantially V-shaped configuration having an apex, each base segment having a first end and a second end wherein the first end of the first base segment is joined to the first end of the second base segment at the apex of the V-shaped configuration as so to define a first interior angle between the first base segment and the second base segment of less than about 180°; and first and second substantially straight legs each having a first end and a second end terminating, wherein each second end terminates in a point, the first and second legs being connected at the first ends to the second ends of the first and second base segments respectively; and wherein the points of the first and second legs extend generally toward each other from the second ends of first and second base segments on converging paths.

Claim 3

A surgical staple according to claim 1, wherein the staple in a deformed state has a substantially configuration bent at at least one point in each base segment and bent at the apex to a second interior angle larger than the first interior angle.

Claim 4

A surgical staple according to claim 2, wherein the first interior angle is less than or equal to about 90°.

Claim 5

A surgical staple according to claim 3, wherein the second interior angle is about 180°.

Claim 6

A surgical staple according to claim 2, wherein the staple in an intermediate deformed state is bent at the apex to the second interior angle.

Claim 7

A surgical staple according to claim 5, wherein the staple has an axis of symmetry drawn through the apex and dividing the first base segment and the first leg from the second base segment and the second leg, wherein the staple has a maximum width measured lateral to the axis of symmetry, and wherein the maximum width of the staple in the un-deformed state is narrower than the maximum width of the staple in the intermediate deformed state and narrower than the maximum width of the staple in the deformed state.

Claim 8

A surgical staple according to claim 2, wherein the staple has an axis of symmetry drawn through the apex and dividing the first base segment and the first leg from the second base segment and the second leg, wherein the staple has a maximum width measured lateral to the axis of symmetry, and wherein the maximum width of the staple in the un-deformed state is narrower than the maximum width of the staple in the deformed state.

Claim 9

A surgical staple according to claim 1, wherein the first interior angle is less than or equal to about 90°.

Claim 10

A surgical staple according to claim 1, wherein the first and second base segments and the first and second legs are substantially planar in configuration.

Claim 11

A surgical staple, comprising: a base having first and second base segments defining in an un-deformed state a substantially V-shaped configuration having an apex, each base segment having a first end and a second end wherein the first end of the first base segment is Joined to the first end of the second base segment at the apex of the V-shaped configuration as so to define a first interior angle between the first base segment and the second base segment of less than about 180°; and first and second legs each having a first end and a second end, the first and second legs being connected substantially perpendicular at the first ends to the second ends of the first and second base segments respectively, wherein the staple in a final deformed state has a substantially rectangular configuration bent at at least one point in each base segment and bent at the apex to a second interior angle larger than the first interior angle, and wherein the first and second interior angles are defined with respect to edges of the base segments that are directed inwardly of the substantially rectangular configuration when the staple is in the final deformed state.

Claim 12

A surgical staple, comprising: a base having first and second base segments defining in an un-deformed state a substantially V-shaped configuration having an apex, each base segment having a first end and a second end wherein the first end of the first base segment is Joined to the first end of the second base segment at the apex of the V-shaped configuration as so to define a first interior angle between the first base segment and the second base segment of less than about 180°; and first and second legs each having a first end and a second end, the first and second legs being connected substantially perpendicular at the first ends to the second ends of the first and second base segments respectively, wherein the staple in a final deformed state has a substantially rectangular configuration bent at at least one point in each base segment and bent at the apex to a second interior angle larger than the first interior angle, and wherein the first and second interior angles are defined with respect to edges of the base segments that are directed inwardly of the substantially rectangular configuration when the staple is in the final deformed state.

Claim 13

A surgical staple according to claim 10, wherein the second ends of the first and second legs each terminate in a sharp point.

Claim 14

A surgical staple according to claim 11, wherein the points of the first and second legs extend generally toward each other from the second ends of the first and second base segments on converging paths.
