illustrative apparatus in accordance with the principles of the present invention are illustrated in fig1 . such apparatus may include jar 19 and lid 12 to store and transport a heart valve prosthesis that has been prepared for surgical implant . lid 12 may be fitted with lid liner 14 . heart valve 11 may be attached to valve holder 13 and support 18 . when valve holder 13 , heart valve 11 , and support 18 are assembled within jar 19 as shown in fig1 , heart valve 11 is suspended within jar 19 by being vertically constrained between lid liner 14 and the base of jar 19 . the heart valve holder and support assembly may be rotationally constrained by tabs 17 in the base of jar 19 . in general , jar 19 contains heart valve 11 with support 18 resting on the base of jar 19 and valve holder 13 resting above heart valve 11 . however , the orientation of heart valve 11 may vary depending on the intended use . for example , a replacement mitral valve may be stored ( i . e ., held ) with the valve leaflets and commissure posts extending downwardly from the level of the valve &# 39 ; s sewing cuff , whereas aortic and supra valves may be held with the valve leaflets and commissure posts extending upwardly from the level of the valve &# 39 ; s sewing cuff . valve holder 13 may include an internal rotating mechanism to deflect the lower ends of the commissure posts radially inward . in the case of a replacement mitral valve , valve holder 13 may engage the sewing cuff of replacement heart valve 11 at locations annularly spaced around the valve . when holding aortic and supra replacement valves , valve holder 13 may be designed to engage the ends of the commissure posts of the replacement heart valve . heart valve 11 should be packaged such that the entire prosthesis is always completely immersed in the storage solution . this is typically achieved by completely filling jar 19 with storage solution . however , lid liner 14 may be designed to displace some of the volume of jar 19 . thus , jar 19 does not have to be completely filled with storage solution to ensure total immersion of heart valve 11 . apparatus in accordance with the principles of the present invention may also include holder handle 15 . an enlarged detailed view of one embodiment of a support is shown in fig2 . support 23 ( which may be used as support 18 of fig1 ) may include finger tabs 22 , ring 24 , struts 29 , and grips 28 . grips 28 may be designed to grip the sewing cuff or other suitable gripping surface of a prosthetic heart valve . finger tabs 22 may be squeezably operable to release grips 28 from a supported prosthetic heart valve . additionally , finger tabs 22 may provide resting support for support 23 within jar 19 . ring 24 may protect a stored heart valve from colliding with the wall of jar 19 if jar 19 is dropped or subjected to some other form of shock or impact . support 23 may attach directly to the sewing cuff of heart valve 11 . support 23 may alternatively be attached to valve holder 13 . some heart valve support products support the holder from above , obstructing the handle attachment means when the storage container is opened . thus , to attach a handle to the replacement valve and holder , the support must first be removed . support 23 may support a heart valve from below , and may engage a feature of the replacement valve instead of the holder . this feature enables immediate handle attachment and eliminates the codependence of the holder and support , allowing either component to be changed without affecting the other . supports like support 23 may be adapted for one - step removal . in such designs , ring 24 which connects three upstanding struts 29 may act as a pivot point . when finger tabs 22 below ring 24 are pressed toward the flow axis of the valve , grips 28 rotate away from the valve &# 39 ; s sewing cuff or other engagement surface and release the valve . this feature simplifies the operating room procedure as current valve supports require a more complex method to remove the support from the valve ( e . g ., multiple disassembly steps , cutting a suture , etc .). fig3 illustrates heart valve 11 with holder 13 and support 18 attached by grips 28 after the lid and lid liner have been removed from jar 19 . holder 13 may be attached to valve 11 by sutures that pass through eyelets 34 and sewing cuff 36 . holder 13 may have cutting grooves 38 so that sutures securing valve 11 to holder 13 can be easily cut at the appropriate time to remove valve 11 from holder 13 . as shown in fig3 , holder 13 may include threads 32 for the attachment of holder handle 15 ( see fig1 ). as shown in fig4 , holder handle 15 is threaded into valve holder 13 such that threads 42 of holder handle 15 threadably engage threads 32 of valve holder 13 . this secures valve / holder / support assembly 50 ( see fig5 ) to holder handle 15 . because threads 32 are exposed upon the removal of the combined lid and lid liner , there is no reason for the scrub nurse or surgeon to actually reach into jar 19 with their sterile , gloved hands . holder handle 15 is inserted directly into jar 19 to remove assembly 50 ( see fig5 ) from jar 19 . alternatively , holder handle 15 may snap into holder 13 , or any other suitable attachment mechanism may be used . because holder handle 15 is threaded into valve holder 13 , it is important that support 18 is able to hold the valve securely while holder handle 15 is tightened . to increase the torsional force that can be applied to valve holder 13 before sewing cuff 36 would begin to slip through grips 28 of support 18 ( e . g ., rotate about the holder handle axis and slide through the grips ), small ridges ( see , e . g ., ridges 210 of fig2 ) may be added to grips 28 . fig5 illustrates assembly 50 removed from jar 19 ( not shown ). assembly 50 may include support 18 , heart valve 11 , and holder 13 . once assembly 50 is removed , heart valve 11 is rinsed . a preferred rinse procedure may include filling three sterile basins with sterile isotonic saline . assembly 50 and the portion of holder handle 15 that was submerged in the valve storage solution should be fully immersed in the sterile isotonic saline solution of the first basin . the valve may be rinsed in the first basin for a fixed period of time with a gentle back and forth motion . the rinse process may be repeated in each of the three basins . once the rinse procedure is completed , assembly 50 may be left immersed in the third basin until the surgeon is ready for implantation . preferably , all of assembly 50 is rinsed , so that everything in fig5 is sterile and free of aldehyde residuals ( or toxic residuals ) and ready for the operating environment . once the rinse process is completed , finger tabs 22 below ring 24 are pressed toward the flow axis of the valve ( illustrated by arrows 62 ) as shown in fig6 , rotating grips 28 away from sewing cuff 36 of heart valve 11 ( illustrated by arrows 64 ). this releases heart valve 11 and valve holder 13 from support 18 . because support 18 was rinsed and sterilized with heart valve 11 , the surgeon or scrub nurse is free to squeeze tabs 22 with his or her gloved hand . as shown in fig7 , support 18 is pulled away from heart valve 11 and valve holder 13 . at this point , heart valve 11 and valve holder 13 are ready to be handed to the surgeon for installation in the patient in the assembly shown in fig8 . holder handle 15 and valve holder 13 may be removed from the patient in one piece once the installation procedure is completed . fig9 shows a top - down view of jar 110 , which is another illustration of a jar in accordance with the principles of the present invention , like jar 19 of fig1 . to prevent a valve / holder / support assembly , like assembly 50 of fig5 , from rotating in jar 110 when the handle is threaded into the valve holder , a number of tabs 117 may be added to the bottom of jar 110 , like those shown in fig9 and 10 . tabs 117 interfere with the finger tabs on the heart valve support and prevent the valve / holder / support assembly from rotating freely in the jar . fig9 - 13 show details of jar 110 , including lid threads 112 and tabs 117 . a lid liner , such as lid liner 140 illustrated in fig1 - 18 , may increase the effectiveness of the valve storage container . lid liner 140 may be press fit into the lid of a jar like jar 19 and is removed from the jar when the lid is removed . when the lid is attached to the jar , cylindrical boss 142 extends from the lid liner into the jar and reduces the volume of storage solution in the jar . due to these two factors , the fluid level in the jar is reduced to well below the rim of the jar when the lid is removed , greatly reducing the possibility of spilling storage solution in the operating room . lid liner 140 may be used to vertically secure a valve / holder / support assembly in a jar and prevent damage during shipping . cylindrical boss 142 of lid liner 140 may be hollowed out so that it is able to flex and secure valve / holder / support assemblies of varying heights . hollow region 160 is shown in fig1 . fig1 - 18 show the details of a lid liner in accordance with the principles of the present invention . fig1 - 33 illustrate the details of various embodiments of a heart valve support in accordance with the principles of the present invention . specifically , fig1 - 23 show features of an aortic valve support , fig2 - 28 show features of a mitral valve support , and fig2 - 33 show features of a supra valve support . the support may be flexible so that one support can accommodate the entire size range for each type of heart valve , eliminating the need for supports of different sizes . fig1 shows aortic valve support 190 . aortic valve support 190 may have struts 192 , grips 194 , ring 196 , and finger tabs 200 ( see fig2 ). grips 194 may have torsional ridges 210 ( see fig2 ) that have been designed to fit within small grooves in the sewing cuff fabric and are asymmetric to preferentially resist handle tightening . aortic support 190 engages the sewing cuff of a replacement aortic valve at locations annularly spaced around the valve . fig2 illustrates support 240 , which may have special features adapted for supporting a replacement mitral valve . a holder , like valve holder 13 of fig1 , may engage a replacement mitral valve adjacent the sewing cuff in three areas that are spaced from one another annularly around the valve . support 240 may engage the sewing cuff at locations that are annularly intercalated with and spaced from the locations at which the holder engages the valve . mitral valve support 240 may have struts 242 , grips 244 , ring 246 , and finger tabs 250 ( see fig2 ). grips 244 may have torsional ridges 260 ( see fig2 ) that have been designed to fit within small grooves in the sewing cuff fabric and are asymmetric to preferentially resist handle tightening . mitral support 240 engages the sewing cuff of a replacement mitral valve at locations annularly spaced around the valve . fig2 shows support 290 for engaging a supra replacement heart valve . supra support 290 engages the sewing cuff of a replacement supra valve at locations annularly spaced around the valve , and may have struts 292 , grips 294 , ring 296 , and finger tabs 300 ( see fig3 ). grips 294 may have torsional ridges 310 ( see fig3 ) that have been designed to preferentially resist handle tightening . as seen in fig1 - 33 , various features of the struts , grips , rings , and tabs may be modified to support the various types of replacement heart valves . however , the basic structural principles of these support structures remain consistent in accordance with the principles of the present invention . it will be understood that the foregoing is only illustrative of the principles of the invention , and that various modifications can be made by those skilled in the art without departing from the scope and spirit of the invention . for example , the order of some steps in the procedures that have been described are not critical and can be changed if desired . also , various steps may be performed with various techniques .
systems and methods for supporting a replacement heart valve are presented herein . a bioprosthesis may be stored in a storage container by suspending the bioprosthesis from a support structure . the volume of storage solution may be reduced by using a lid with a boss extending therefrom to displace some of the volume of the storage container . the support structure may rest on the base of the storage container . additionally , there may be a holder attached to the bioprosthesis above the support structure . the holder - bioprosthesis - support structure may be constrained between the lid and base of the storage container .
