## Title
Transcend surgical clips for laproscopic procedures

## Abstract

A surgical clip for a clip applier to ligate vessels. The clip contains two opposing external and internal legs connected in parallel by two external apex and one internal apex to form a Y-shape configuration. As a vessel is ligated and compressed between the two external legs, the vessel attempting to expand from its compressed position, applies outwardly lateral forces to the external legs causing them to rotate outwardly. In response, the two opposing internal legs rotate in an opposing directions to the external legs rotations to maintain the position of the clip over the compressed tubular vessel.

FIELD OF THE INVENTION
This invention relates to novel surgical ligation clips for ligating blood vessels during laparoscopic or endoscopic procedures.
BACKGROUND OF INVENTION
In order to operate on a given tissue or a blood vessel, surgeons must ligate or occlude nearby blood vessels to prevent patient blood loss. Surgeons employ small surgical clips and long cartridges within the clip appliers to ligate or occlude blood vessels in laparoscopic and endoscopic surgical procedures. These surgical clips need to perform multiple functions.
First, the surgical clip must be securely located on the blood vessel. Movement or slippage of the surgical clip on the vessel should be minimized or eliminated once the clip has been applied. Second, the surgical clip should completely close the blood vessel to which it is applied. Movement or slippage of the surgical clip or failure to fully close a blood vessel may cause one or more of the following: damage to nearby tissue, interference on the surgical site, patient blood loss, a lethal drop in blood pressure, or loss of the clip inside the patient. Third, the surgical clip should be designed to minimize damage to the closed blood vessel and surrounding tissue as much as possible. Surgical clips that cause tissue or blood vessel damage may result in internal bleeding, a lethal drop in blood pressure, infections, or longer recovery periods.
Examples of surgical clips are described in U.S. Pat. Nos. 6,610,073; 6,217,590; 5,509,920; 5,501,693; 5,201,746; 5,171,253; 5,171,252; 5,100,420; 5,084,057; 5,026,382; 4,971,198; 4,976,722; 4,979,950; 4,844,066; 4,799,481; 4,702,247; 4,414,721; 4,188,953; 4,146,130; 3,867,944; and 3,363,628; and U.S. Published Patent Application Nos. 2007/0173866; 2005/0273122; and 2004/0153107; all of which are herein incorporated by reference in their entirety.
Previously disclosed surgical clips have two surgical legs defined by a pair of legs joined at a proximal end by an apex and spaced apart at a distal end to define a space between the legs. A clip applier places a surgical clip over a blood vessel within this space and releases the spring loaded legs to ligate the vessel.
However, the previously disclosed surgical clips have legs that do not close or open in directions that are substantially parallel to each other. Non-parallel closure over a vessel leads to clip slippage on the vessel.
Thus, the previously disclosed surgical clips are not adequately secured on blood vessel
Accordingly, the subject invention is a novel surgical clip with two legs that close in a substantially parallel way, with less dependence on the position and size of the tissue occluded, thereby securely fastening to and closing a blood vessel while minimizing slippage and damage to the vessel.

DETAILED DESCRIPTION OF THE EMBODIMENTS
While several variations of the present invention have been illustrated by way of example in particular embodiments, it is apparent that further embodiments could be developed within the spirit and scope of the present invention, or the inventive concept thereof. However, it is to be expressly understood that such modifications and adaptations are within the spirit and scope of the present invention, and are inclusive, but not limited to the following appended claims as set forth.
The subject invention comprises a transcend ligating clip 1, as shown in FIGS. 1-7. In one embodiment of the subject invention, the clip 1 may have a substantially Y-shaped configuration.
FIG. 1 illustrates the ligating clip 1 in the open or uncompressed position. The ligating clip 1 will be in an open position before attachment or application over a blood vessel to ligate or occlude that vessel. FIGS. 2, 4, 6, and 7 illustrate the closed or compressed position of ligating clip 1 alone and clamped over a tubular vessel V.
The ligating clip 1 includes a pair of opposed elongated ligating legs 2 and 3, each having respective distal ends 2a and 3a, and respective proximal ends 2b and 3b. The distal ends 2a and 3a of ligating legs 2 and 3 are substantially parallel to one another and are relatively non-deformable.
The ligating leg 2 proximate to proximal end 2b extends in a outwardly lateral direction to form an external bending leg 2c. The external bending leg 2c curves in an inwardly lateral direction at proximal end 2b to form an internal bending leg 2d. The proximal end of 2b of external bending leg 2c and internal bending leg 2d curve towards each other, in an inwardly lateral direction, to form a first leg apex connection 2e. The first leg apex connection 2e is relatively deformable to allow clip 1 to compress from the open position to the closed position. A narrow channel 2f is formed between the external bending leg 2c and the internal bending leg 2d. 
In further embodiments of the subject invention, the ligating leg 2 have may have variable cross-sectional widths from the distal end 2a to the external bending leg 2c to the proximal end 2b to internal bending leg 2d to the first leg apex connection 2e to minimize deflection of the clip 1 as it moves between the compressed and the uncompressed positions.
In other embodiments of the subject invention, the ligating leg 2 may have a continuous or variable cross-sectional shape from the distal end 2a to the external bending leg 2c to the proximal end 2b to internal bending leg 2d to the second leg apex connection 2e, wherein this shape may be selected from square, circular, elliptical, triangular, hexagonal, octagonal, or any suitable cross-sectional shape.
Ligating leg 2 contains an inner tissue contacting surface 5 and an outer surface 6 that both extend along the axis of ligating leg 2 in a substantially parallel direction.
The ligating leg 3 proximate to proximal end 3b extends in an outwardly lateral direction to form an external bending leg 3c. The external bending leg 3c curves in an inwardly lateral direction at proximal end 3b to form an internal bending leg 3d. The proximal end of 3b of external bending leg 3c and internal bending leg 3d curve towards each other, in an inwardly lateral direction, to form a second leg apex connection 3e. The second leg apex connection 3e is relatively deformable to allow clip 1 to compress from the open position to the closed position. A narrow channel 3f is formed between the external bending leg 3c and the internal bending leg 3d. 
In further embodiments of the subject invention, ligating leg 3 have may have variable cross-sectional widths from the distal end 3a to the external bending leg 3c to the proximal end 3b to internal bending leg 3d to the second leg apex connection 3e to minimize deflection of the clip 1 as it moves between the compressed and the uncompressed positions.
In other embodiments of the subject invention, the ligating leg 3 may have a continuous or variable cross-sectional shape from the distal end 3a to the external bending leg 3c to the proximal end 3b to internal bending leg 3d to the second leg apex connection 3e, wherein this shape may be selected from square, circular, elliptical, triangular, hexagonal, octagonal, or any suitable cross-sectional shape.
Ligating leg 3 contains an inner tissue contacting surface 7 and an outer surface 8 that both extend along the axis of ligating leg 3 in a substantially parallel direction.
Ligating legs 2 and 3 are substantially mirror images of each other. Proximal end 2b is substantially a mirror image of proximal end 3b. External bending leg 2c is substantially a mirror image of external bending leg 3c. Internal bending leg 2d is substantially a mirror image of internal bending leg 3d. The first leg apex connection 2e is substantially a mirror image of second leg apex connection 3e. Narrow channel 2f is substantially a mirror image of narrow channel 3f. 
Ligating legs 2 and 3 each have a contiguous cross-sectional configuration. This configuration is maintained as ligating legs 2 and 3 curve to form external bending legs 2c and 3c, and curve to form internal bending legs 2d and 3d, and then curve towards each other to form an apex connection 4.
FIG. 7 illustrates an enlarged cross-sectional view of ligating legs 2 and 3. Inner tissue contacting surface 5 and outer surface 6 form a cross-sectional configuration for ligating leg 2. Inner tissue contacting surface 7 and outer surface 8 form a cross-sectional configuration for ligating leg 3. Ligating legs 2 and 3 are substantially equivalent in size and shape. The cross-sectional size and shape of distal end 2a is substantially equivalent in size and shape to distal end 3a. The cross-sectional size and shape of external bending leg 2c is substantially equivalent in size and shape of external bending leg 3c. The cross-sectional size and shape of internal bending leg 2d is substantially equivalent in size and shape of internal bending leg 3d. 
The distal ends 2g and 3g of the internal bending legs 2d and 3d curve towards each other, in an inwardly lateral direction, to form a clip apex connection 4. The distal, internal side of clip apex connection 4 forms within an internal movement space 10. Narrow channels 2f and 3f both end within internal movement space 10. The proximal, external side of clip apex connection 4 forms within an external movement space 11. The clip apex connection 4 is relatively deformable to allow the clip 1 to compress from the open position to the closed position within internal movement space 10 and an external movement space 11.
A clip applier with a jaws assembly (not shown) containing two opposing jaws legs, compresses and reduces the diameter of a tubular vessel V to be occluded or ligated with clip 1. This reduction in vessel V diameter prior placement of the clip 1, permits a vessel V with a much larger diameter than the distance between ligating legs 2 and 3 to be contained within clip 1.
The clip 1 is slid over compressed vessel V. As illustrated in FIG. 7, the vessel V is held between inner tissue contacting surface 5 of ligating leg 2 and inner tissue contacting surface 7 of ligating leg 3.
The compressed tubular vessel V, attempting to expand from its compressed position to an uncompressed position, applies outwardly lateral force F1 to inner tissue contacting surface 5 of ligating leg 2, and outwardly lateral force F2 to inner tissue contacting surface 7 of ligating leg 3. Outwardly lateral force F1 and outwardly lateral force F2 are substantially opposing forces.
Outwardly lateral force F1 on inner tissue contacting surface 5 of ligating leg 2 causes external bending leg 2c to rotate in direction R1 in a lateral direction away from internal bending leg 2d at the first leg apex connection 2e. In response to rotation R1, internal bending leg 2d begins to rotate in direction R2 in a lateral direction towards external bending leg 2c at apex 4. Rotation R2 substantially opposes rotation R1 to maintain the position of ligating leg 2 on the clip 1 over the compressed tubular V.
Outwardly lateral force F2 on inner tissue contacting surface 7 of ligating leg 3 causes external bending leg 3c to rotate in direction R3 in a lateral direction away from internal bending leg 3d at a first leg apex connection 3e. 
Outwardly lateral force F2 on inner tissue contacting surface 5 of ligating leg 7 causes external bending leg 3c to rotate in direction R3 in a lateral direction away from internal bending leg 3d at the second leg apex connection 3e. In response to rotation R3, internal bending leg 3d begins to rotate in direction R4 in a lateral direction towards external bending leg 3c at apex 4. Rotation R4 substantially opposes rotation R3 to maintain the position of ligating leg 3 on the clip 1 over the compressed tubular vessel V
Rotations R1 on external bending leg 2c and R3 on external bending leg 3c are substantially mirror images of each other. Rotations R2 on internal bending leg 2d and R4 on internal bending leg 3d are substantially mirror images of each other.
Rotations R2 and R4, oppose the rotations R1 and R3, respectively, caused by uncompressing forces F1 and F2 from the compressed vessel V, to maintain the substantially parallel position of ligating legs 2 and 3 over the compressed vessel V.
The vessel V will be remain occluded or ligated between the opposing inner tissue contacting surface 5 and the inner tissue contacting surface 7. The continuous outer surface of clip 1 will reduce irritation and trauma in tissue surrounding the ligated vessel V, since it does not have any sharp corners or edges that may pierce or cut surrounding tissue.
FIG. 6 illustrates the closed position of surgical vessel ligating clip 1 attached to vessel V. Ligating leg 3 is compressed over ligating leg 2. No internal fluid traverses vessel V when clip 1 is compressed over the vessel. The inner tissue contacting surfaces 5 and 7 promote ligation or occlusion of a tubular blood vessel without piercing or cutting the vessel. Once the surgical clip 1 is closed or compressed over a tubular vessel, the vessel tissue may gradually move or ooze into the spaces between inner tissue contacting surfaces 5 and 7 while remaining frictionally engaged such that the clip 1 does not move or become loose on the vessel.
In one embodiment of the subject invention, the clip 1 is 0.1 to 0.5 inches in length or width. In another embodiment of the subject invention, the clip is 0.25 inches in length. In a further embodiment of the subject invention, the clip 1 is intended to be used with a five millimeter trocar. In a further embodiment of the subject invention, the clip 1 is composed of titanium, stainless steel, tantalum, plastics materials, or a combination thereof. In an even further embodiment of the subject invention, the clip 1 is composed of biodegradable material.
