[ 0031 ] fig3 illustrates a suture 20 after packaging in accordance with the present invention . suture 20 includes a suture material or thread 22 having suture needles 24 , 26 at opposite ends and formed into a series of non - uniform loops 22 a , 22 b . these loops do not tend to become tangled or form air knots when removed from packaging of the present invention . in addition , these loops do not form nearly the permanent or semi - permanent set formed by current and past suture packaging methods . [ 0032 ] fig4 illustrates an unfolded accordion - style package 30 constructed in accordance with the preferred embodiment . package 30 includes an accordion - style paper panel 32 having a series of folded subpanels 32 a . although paper is the currently preferred material for the various elements of package 30 , other materials may be used as well . subpanels 32 a are separated by outer folds 34 and inner folds 36 . alternating panels 32 a include integrated or otherwise connected flaps 38 which fold over from the top edge of panel 32 to apply slight compression to suture material 22 after the packaging operation is complete . holes 40 are provided in these alternating subpanels 32 a and a like series of three holes 42 are provided in the corresponding flaps 38 . when flaps 38 are folded over , holes 40 register in alignment with holes 42 . holes 40 receive respective pins ( not shown ) extending from a suitable packaging fixture to allow suture material 22 to be directed in the manner shown in fig4 . respective tabs 44 angle slightly upward from tabs 39 affixed to the opposite alternating series of subpanels 32 a and receive lower loops of the suture material 22 . this is more specifically shown in fig4 a . tabs 44 are at staggered distances from the respective series of holes 40 to create the uneven loop pattern discussed above and shown in fig3 . an inner stiff panel 50 in package 30 has a three - dimensional configuration formed by a lip 52 for purposes to be discussed in greater detail below . an opening 54 is provided in flap 50 to expose needle 24 to allow removal of suture 20 by the user . an outer flap 60 is provided to enclose and secure the entire package in its folded condition ( fig9 ). [ 0033 ] fig5 and 8 illustrate the accordion - style panel 32 as well as outer fold lines 34 and inner fold lines 36 . as shown best in fig7 inner fold lines 36 are embossed to prevent adjacent subpanels 32 a from pinching suture material 22 in the folded condition . also , outer fold lines 34 are scored on the back side as opposed to the front side thereof to prevent suture material 22 from hanging up or becoming caught on fractured paper fibers when directed over the fold line 34 , as shown in fig6 . [ 0034 ] fig9 illustrates the package 30 in its fully folded and secured condition . in this illustration , it should be noted that stiff panel 50 and lip 52 prevent package 30 from being significantly crushed and thereby pinching the suture after packaging . this feature further inhibits kinking or causing suture 20 to hang up as it is withdrawn from package 30 . [ 0035 ] fig1 illustrates a portion of suture 20 illustrating the transition between suture material 22 and needle 24 . in accordance with the invention , this transition zone is substantially straight and , due to the packaging principles expressed herein , needle 24 is not permanently or semi - permanently set into a kinked or angled position with respect to suture material 22 . [ 0036 ] fig1 illustrates an alternative subpanel 32 a ′ which may be used in the end subpanel , for example , adjacent flap 60 ( fig4 ). subpanel 32 a ′ includes elongated slots 40 ′ adapted to carry adjustable pins 70 during the packaging operation . for example , pins 70 may extend upwardly from a fixture ( not shown ) and may adjust in position along the length of slots 40 ′ to adjust and accommodate the length of a particular suture . [ 0037 ] fig1 schematically illustrates accordion - style panel 32 and suture material 22 directed in a generally serpentine fashion over adjacent subpanels 32 a . subpanels 32 a prevent adjacent loops of suture material 22 from contacting one another when accordion - style panel 32 is folded as shown in fig1 and then compressed as shown in fig9 . as understood from reviewing fig4 the packaging operation involves unfolding accordion - style panel 32 into a flat condition and placing holes 40 over separate series of extendable and retractable pins ( not shown ) associated with a suitable fixture . once panel 32 is stretched out into this flat condition and retained on the fixture pins , suture 20 may be successively directed around the pins extending through holes 40 and also around tabs 44 as shown in the drawing . once this is accomplished , flaps 38 are folded over such that the pins extend through holes 42 . the pins are then retracted and accordion - style panel 32 is immediately folded into its compressed condition shown in fig9 . flap 50 is folded over first and then flap 60 is secured around the outside thereof , such as by using a suitable adhesive . to withdraw suture 20 , the user preferably grasps both of the exposed needles 24 , 26 and pulls suture 20 from package 30 . [ 0039 ] fig1 and 13a illustrate an alternative accordion - style package 80 shown in partial form , with suture material 22 directed therethrough in a similar fashion to the previously described embodiment . package 80 includes a plurality of accordion - style folded subpanels 82 connected by fold lines 84 , 86 . alternating subpanels 82 have flaps 88 folded over from upper ends thereof , while subpanels 82 therebetween include folded over flaps 90 affixed to the respective subpanel 82 to form a tab 92 in a manner and for reasons similar to the previously described embodiment . in this embodiment , flaps 88 are perforated into subpanels 82 as shown in fig1 a and along a curved path following the path of suture material 22 . this forms a track to retain suture material 22 in the intended looping configuration above the perforations 100 . as suture material 22 is pulled downwardly from package 80 , as viewed in fig1 , the connections between subpanels 82 and flaps 88 formed by perforations 100 will break and allow suture material to be withdrawn from package 80 in the previously described controlled manner . [ 0040 ] fig1 , 14a and 15 illustrate an alternative embodiment of a suture package 120 . in these figures , like reference numerals indicate like structure or elements with other embodiments of the invention . suture 20 is again retained on an accordion - style panel 122 comprised of a plurality of subpanels 122 a . suture material 22 includes suture needles 24 , 26 at opposite ends and is formed into a series of loops placed on adjacent subpanels 122 a as in previous embodiments . other features of the previous embodiments may or may not also be included in this embodiment . subpanels 122 a are separated by folds 124 , 126 and suture material 122 crosses these folds at an angle a which is obtuse and preferably approaches parallel relative to the fold lines 124 or 126 . for example , suture material 30 is ideally within about 30 ° of parallel ( angle α ≧ 150 °) to fold lines 124 or 126 as it crosses from one subpanel to the next . the main difference between suture package 120 and the suture packages of the previous embodiments is that suture needles 24 , 26 exit suture package 120 along a side edge of package 120 , as best shown in fig1 a and 15 , instead of exiting at one end . this allows suture 20 to be pulled out essentially in a perpendicular direction to the fold lines 124 , 126 as shown in fig1 . therefore , suture material 22 is not dragged along fold lines 126 . it has been found that outer fold lines 126 may have discontinuities which tend to snag on suture material 22 if suture material 22 is pulled out from one end of package 120 as opposed to being pulled out along the long side as shown in fig1 . thus , this embodiment prevents this snagging and any potential damage to the suture material 22 which results therefrom . as further shown in fig1 and 14a , a pair of paper flaps 130 , 132 may be used to secure panel 122 in its folded condition , such as by adhesively securing flaps 130 , 132 in the positions shown in fig1 a . package 120 may then be placed in a suitable holder , such as a flat hollow paper holder 140 for final packaging and shipping purposes . as an alternative , this separate outer package portion or holder 140 may be an integral member such as a flap . as further shown in fig1 , when suture package 120 is ready for use , package 120 is partially or fully removed from holder 140 and a suitable surgical implement 142 is used to pull suture 20 from package 120 . this embodiment retains the advantages of the previously described embodiments in terms of providing a non - kinking and non - tangling suture , and further prevents any potential suture damage or other difficulties as the suture 20 is quickly removed at the point of use . while the present invention has been illustrated by a description of a preferred embodiment and while this embodiment has been described in some detail , it is not the intention of the applicants to restrict or in any way limit the scope of the appended claims to such detail . additional advantages and modifications will readily appear to those skilled in the art . the various features of the invention may be used alone or in numerous combinations depending on the needs and preferences of the user . this has been a description of the present invention , along with the preferred methods of practicing the present invention as currently known . however , the invention itself should only be defined by the appended claims , wherein
a suture package including a panel having a series of superimposed subpanels . a suture loops back and forth on the subpanels such that adjacent loops are retained on adjacent subpanels and the adjacent subpanels separate the adjacent loops from one another . in the preferred embodiment , an accordion style panel is utilized and the series of subpanels are folded into a superimposed relationship . various features are incorporated to reduce the instances or likelihood of kinking and tangling of the suture when pulled from the package by a user .
