Claim 3

The hemostatic clip of claim 1, wherein the intersection of said indentation with said side surface defines an open area in said side surface to permit the flow of body fluid therethrough to body tissue.

Claim 4

The hemostatic clip of claim 1, wherein said clip comprises a plurality of said indentations arranged in first and second rows, said indentations intersecting with a respective one or the other of said side surfaces.

Claim 5

The hemostatic clip of claim 3, wherein the indentations of one of said first and second rows are in staggered arrangement with respect to the indentations of the other of said first and second rows.

Claim 6

The hemostatic clip of claim 3, wherein said first and second legs each include a distal end portion, said distal end portions of said first and second legs extending in generally parallel orientation to each other, and said legs each further including a proximal portion, said proximal portions being joined at an angle so as to define an apex and a bail portion of the hemostatic clip.

Claim 7

The hemostatic clip of claim 5, wherein said bail portion is generally V-shaped.

Claim 8

The hemostatic clip of claim 6, wherein the angle between the proximal portions of the first and second legs is from about 129° to about 131°.

Claim 9

The hemostatic clip of claim 5, wherein said bail portion is generally U-shaped.

Claim 10

The hemostatic clip of claim 5, further including at least one notch extending lengthwise on at least one of said proximal portions.

Claim 11

The hemostatic clip of claim 9, wherein said notch has a V-shaped cross section.

Claim 12

The hemostatic clip of claim 5, wherein the indentations are located on the tissue contacting surfaces of the distal end portions of the first and second legs.

Claim 13

The hemostatic clip of claim 1, wherein said wall includes at least one edge formed by the intersection of said wall with a respective one of said side surfaces.

Claim 14

The hemostatic clip of claim 12, wherein said wall is of generally arcuate configuration.

Claim 15

The hemostatic clip of claim 12, wherein said wall is of generally semicircular configuration.

Claim 16

The hemostatic clip of claim 12, wherein said wall is substantially perpendicular to the tissue contacting surface.

Claim 17

The hemostatic clip of claim 1, wherein said clip is fabricated from a material selected from the group consisting of stainless steel, tantalum, titanium, and plastic.

Claim 18

A hemostatic clip for application to body tissue, which comprises: first and second legs, each leg having a tissue contacting surface and at least two side surfaces intersecting said tissue contacting surface and defining a width of said leg therebetween, said first and second legs being formable from a relatively spaced apart position for reception of tissue therebetween to a closed position wherein the legs are in close proximity to each other for clamping tissue therebetween, said tissue contacting surface having at least one indentation disposed thereon across less than the entire width of the tissue contacting surface and intersecting one of said side surfaces, said indentation being completely defined by at least one wall which intersects said tissue contacting surface and an indentation base surface which intersects said wall and said one side surface.

Claim 19

A hemostatic clip for application to body tissue, which comprises: first and second legs, each leg having a tissue contacting surface and at least two side surfaces intersecting said tissue contacting surface and defining a width of said leg therebetween, said first and second legs being formable from a relatively spaced apart position for reception of tissue therebetween to a closed position wherein the legs are in close proximity to each other for clamping tissue therebetween, said tissue contacting surface having at least one indentation disposed thereon across less than the entire width of the tissue contacting surface and intersecting one of said side surfaces, said indentation being completely defined by at least one wall which intersects said tissue contacting surface and an indentation base surface which intersects said wall and said one side surface.

Claim 20

A hemostatic clip for application to body tissue, which comprises: first and second legs, each leg having a substantially flat tissue contacting surface and at least two side surfaces intersecting said tissue contacting surface and defining a width of said leg therebetween, said tissue contacting surface having at least one indentation disposed thereon across less than the entire width of the tissue contacting surface and intersecting one of said surfaces, said indentation being completely defined by a wall which intersects said tissue contacting surface and an indentation base surface which intersects said wall and one of said side surfaces, the depth of said at least one indentation being less than the depth of the leg on which the indentation is disposed.

Claim 21

A hemostatic clip for application to body tissue, which comprises: first and second legs, each leg having a substantially flat tissue contacting surface and at least two side surfaces intersecting said tissue contacting surface and defining a width of said leg therebetween, said tissue contacting surface having at least one indentation disposed thereon across less than the entire width of the tissue contacting surface and intersecting one of said surfaces, said indentation being completely defined by a wall which intersects said tissue contacting surface and an indentation base surface which intersects said wall and one of said side surfaces, the depth of said at least one indentation being less than the depth of the leg on which the indentation is disposed.

Claim 22

A hemostatic clip for application to body tissue, which comprises: first and second legs, each leg having a substantially flat tissue contacting surface and at least two side surfaces intersecting said tissue contacting surface and defining a width of said leg therebetween, said flat tissue contacting surface having at least one indentation disposed thereon across less than the entire width of the tissue contacting surface and intersecting one of said side surfaces, said indentation having at least one wall oriented transverse to said flat tissue contacting surface and a base surface which intersects said wall and said one side surface, said wall and said base surface completely defining said indentation.

Claim 23

A hemostatic clip for application to body tissue, which comprises: first and second legs, each leg having a substantially flat tissue contacting surface and at least two side surfaces intersecting said tissue contacting surface and defining a width of said leg therebetween, said flat tissue contacting surface having at least one indentation disposed thereon across less than the entire width of the tissue contacting surface and intersecting one of said side surfaces, said indentation having at least one wall oriented transverse to said flat tissue contacting surface and a base surface which intersects said wall and said one side surface, said wall and said base surface completely defining said indentation.
