is not shown for clarity . fig2 is an enlarged partial view of fig2 illustrating the position of the o - ring 240 on the now advanced groove 212 of the wedge tip 210 within the shaft tube 230 . fluid is allowed to communicate through the shaft tube 230 by way of the fluid housing 250 and coinciding fluid channels 233 of the shaft tube 230 and over the fluid troughs 213 of wedge tip 210 . fig2 is

detailed in fig2 . the body 83 of sleeve 80 is compressed , but the flange 82 is intact . fig3 shows a schematic illustration of the human heart 40 sectioned to remove the front from the left side of the heart . this heart 40 is shown during diastole which is the filling phase during the cardiac cycle . the right side is not highlighted in this illustration . the left atrium 300 receives blood returning from the lungs through the pulmonary veins 301 and 302 . two pulmonary veins generally enter to the left atrium 300 on the patient &# 39 ; s right side 300 a and two more on the patient &# 39 ; s left atrial side 3008 . note the four open arrows 303 coming from the pulmonary veins 301 and 302 illustrating the return of blood flow to the left atrium 300 . during this phase of the cardiac cycle , the anterior leaflet 304 of the mitral valve 305 and the posterior leaflet 306 of the mitral valve 305 are open to permit the blood returning into the atrium 300 to pass into the left ventricle 307 . note that the chordae tendineae 308 is shown passing from the anterior leaflet 304 of the mitral valve 305 to a papillary muscle 309 in the left ventricle 307 . note that a second chordae tendineae 310 is shown here passing from the posterior leaflet 306 to another papillary muscle 311 . the thin black arrows 312 indicate the opening of the anterior and posterior mitral valve leaflets , 304 and 306 . the aortic valve 314 is shown in the closed position as it is during diastole due to back pressure from blood in the ascending aorta 315 . for purposes of clarity , this illustration does not show the right atrium or the right ventricle . fig3 illustrates the heart 40 now in the contraction phase , systole , of the cardiac cycle . the cardiac walls 316 and septum 317 thicken as the ventricular chamber 318 contracts . the thin black arrows 312 and 313 illustrate that the pressure built up in the left ventricle 307 causes both the anterior mitral leaflet 304 and posterior mitral leaflet 306 to come together and seal at what is called the coaptation zone 319 . the four open arrows illustrate blood leaving the left ventricle and passing through the now open aortic valve 314 . fig3 is similar to fig3 with the schematic heart 40 in systole . however , here the chordae tendineae 308 in fig3 which should be in continuity between the papillary muscle 309 and anterior leaflet 304 of the mitral valve 305 has been disrupted . this disrupted chordae tendineae 320 is shown partially attached to the papillary muscle 309 and partially attached 320 to the anterior leaflet 304 . the coaptation zone 319 between the anterior leaflet 304 and the posterior leaflet 306 is disrupted allowing blood to pass back into the left atrium 300 instead of being blocked by the coapted mitral valve 305 . this passing of blood back into the right atrium is called regurgitation , and the movement of the anterior leaflet into the left atrium is called prolapse . fig3 shows a proper length suture hand - tied replacement 321 for a disrupted chordae tendineae , which is not shown here due to its surgical removal . the open arrows 303 indicating blood show that the blood again passes only towards the now open aortic valve 314 . fig3 is similar to the illustration of fig3 however in fig3 the hand - tied suture replacement 321 of suture 321 a ( for the anterior leaflet 304 disrupted chordae tendineae 308 as shown in fig3 ) is tied too long so that the anterior leaflet 304 can prolapse into the left atrium 300 thereby rendering the coaptation zone 319 dysfunctional . one open arrow illustrates the passage of blood regurgitating back into the left atrium 300 due to inaccurate knotting of the chordae tendineae replacement suture 321 . fig3 is like fig3 and 34 however now the chordae tendineae replacement suture 321 is too short . by tying the replacement suture 321 of suture 321 a too short , the coaptation zone 319 of the mitral valve 305 is rendered open . the inappropriate coaptation of the anterior leaflet 304 leaves a space between the anterior leaflet 304 and the posterior leaflet 306 through which blood can pass as illustrated with the open arrow 323 . fig3 shows the tip of the deployment device 20 of the present invention passing into the schematic left atrium 300 of the human heart 40 . note there are two different loops of suture , 324 and 325 , one coming from the papillary muscle 309 and another coming from the anterior leaflet 304 whose chordae tendineae has been removed . fig3 shows similar illustration as fig3 except now the deployment device 20 has passed completely down onto the papillary muscle 309 in the left ventricle 307 . the suture 324 going from the papillary muscle 309 and through the coaxial mechanical fastener 30 is drawn tight . however the suture 325 going to the anterior leaflet 304 has yet to be drawn down into the proper coaptation alignment . fig3 shows the schematic heart 40 with the deployment device 20 in place on the papillary muscle 309 and now also infusing pressurized saline 326 into the left ventricle 307 to push upon the inside surfaces of both of the mitral leaflets 304 and 306 , as indicated by the thin black arrows 313 . by drawing the suture 325 from the anterior leaflet 304 in , the anterior leaflet 304 is pulled down into position in the appropriate zone for coaptation . when the suture length is properly set , the lever 190 ( not shown ) of the deployment device 20 is squeezed , crimping the coaxial fastener 30 and simultaneously cutting away all redundant suture 324 and 325 through the suture hole ( not shown ). fig3 shows the coaxial fastener 30 in place anchoring the suture 325 coming from the anterior leaflet 304 to the papillary muscle 309 . the double headed arrow 327 indicates the direction of the tension from the papillary muscle 309 up to the anterior leaflet 304 . note that the coaptation zones 319 are completely in contact and the inner surfaces of both the anterior and posterior mitral leaflets 304 and 306 are parallel and aligned . fig4 is a distally oriented perspective view of an additional embodiment of a bidirectional snare device 280 . the bidirectional snare device 280 is formed by first forming a small loop 284 and routing the wire pair 288 through the body 83 of the sleeve 80 . looping the wire pair 288 around the flange 82 of the sleeve 80 . while maintaining a small loop 284 , arrange the wire pair 288 so that one end is substantially longer than the other and create a twisted portion 285 of about ½ inch

which is also typically stainless steel , and applies compressional force onto reel plates 350 , which can be manufactured as machined metal or molded plastic , and subsequently the compression rings 360 . fig5 is an exploded perspective view of the slotted suture securing reel 330 of fig5 . the yard arm 340 is attached to the shaft tube 230 of the deployment device 20 by the compressional force applied by the knurled knob 370 whose threaded bore 371 is threaded onto the threaded shaft 381 of the screw 380 and subsequently compresses the reel plates 350 whose bores 351 fit over the threaded shaft 381 of screw 380 and compression rings 360 whose internal diameters 361 also fit over the threaded shaft 381 of screw 380 . while the invention has been described in connection with a number of presently preferred embodiments thereof , those skilled in the art will recognize that a number of modifications and changes may be made therein without departing from the true spirit and scope of the invention which accordingly is intended to be defined solely by the appended claims .
a method and apparatus for securing separate loops of suture with a coaxial mechanical fastener . separate loops of suture extend from opposite ends of the mechanical fastener . a wire snare facilitates pulling the suture through the fastener . a suturing instrument provides for the infusion of pressurized physiologic solutions into the left ventricle so that the proper replacement suture length can be demonstrated real time prior to crimping the fastener . the instrument incorporates a slotted release site so that the fastener and suture can be released from the device tip once the fastener is secured . a method of securing suture coming from cardiac valve leaflets and or other structures like papillary muscles permits a more atraumatic orientation of the fastener coaxial with the suture strands .
