DETAILED DESCRIPTION OF THE INVENTION [0030] While the invention pertains generally to implanting prosthetic devices in the cardiac venous system, the invention can be illustrated by reference to a procedure performed in and around the coronary sinus and great cardiac vein. Referring now to FIG. 1, it is a superior view of a human heart 10 with the atria removed to expose the mitral valve 12, the coronary sinus 14, the coronary artery 15, and the circumflex artery 17 of the heart 10 to lend a better understanding of the present invention. Also generally shown in FIG. 1 are the pulmonary valve 22, the aortic valve 24, and the tricuspid valve 26 of the heart 10. The coronary sinus 14 as previously defined herein includes the great cardiac vein. As is well known, the coronary sinus becomes the great cardiac vein at some point. Hence, for purposes of describing the implant method of the present invention, the great cardiac vein or great vein 14 a will be referred to as it particularly pertains to the distal end of the device to be implanted. [0031] The mitral valve 12 includes an anterior leaflet 16, a posterior leaflet 18 and an annulus 20. The annulus encircles the leaflets 16 and 18 and maintains their spacing to provide a complete closure during a left ventricular contraction. As is well known, the coronary sinus 14 (and great vein 14 a) partially encircles the mitral valve 12 adjacent to the mitral valve annulus 20. As is also known, the coronary sinus (and great vein) is part of the venus system of the heart and extends along the AV groove between the left atrium and the left ventricle. This places the coronary sinus essentially within the same plane as the mitral valve annulus making the coronary sinus available for placement of the mitral valve therapy device of the present invention therein. [0032] Of particular importance is the physiological relationship of the coronary sinus 14 and the circumflex artery 17. The circumflex artery 17 branches from the coronary artery 15 and supplies blood flow to critical tissue of the heart 10. The circumflex artery passes beneath the coronary sinus 14 such as at crossover point 19 as shown in FIG. 1. It is one aspect of the present invention to avoid constriction of blood flow through the circumflex artery 17 and its branches when a mitral valve therapy device is deployed in the coronary sinus 14 (great vein 14 a). [0033] [0033]FIG. 2 shows a mitral valve therapy device 30 deployed in the coronary sinus 14 of the heart 10 adjacent the mitral valve annulus 20 for affecting the geometry of the mitral valve annulus. The device 30 takes the form of an elongated body 32 which includes a distal anchor 34 and a proximal anchor 36. [0034] The anchors 34 and 36 are shown in FIG. 2 in their deployed configuration. A more complete description of the anchors 34 and 36 and their deployment may be had in copending application Ser. No. 10/142,637, filed May 8, 2002 for BODY LUMEN DEVICE ANCHOR, DEVICE AND ASSEMBLY which is assigned to the assignee of the present invention and hereby incorporated herein by reference. As will be seen hereinafter, in deploying the device 30 in the coronary sinus 14, the distal anchor 34 is first deployed in the great vein 14 a to anchor the distal end of the device 30. In the anchoring process, the anchor 34 is expanded outwardly to anchor the device in the great vein 14 a against both bi-directional longitudinal and rotational movement. This allows the device 30 to be tightened within the coronary sinus by pulling of the device's proximal end. Then, the proximal anchor 36 is deployed. The device 30, which may be formed from Nitinol or stainless steel, for example, now exerts an inward pressure on the mitral valve annulus 20 to advantageously affect its geometry. [0035] The implant of the device 30 is initiated with an assessment of the degree of mitral regurgitation being suffered by the patient. This is accomplished by performing an echocardiogram to document the degree of mitral regurgitation. The echocardiogram may be either a transthoracic echocardiogram or a transesophageal echocardiogram. [0036] Once the degree of mitral regurgitation is assessed, the coronary sinus 14 as illustrated in FIG. 3 is cannulated. The coronary sinus 14 is cannulated with a catheter 40 which is inserted through the ostium 13 of the coronary sinus 14 and into the coronary sinus. The distal end 42 of the catheter 40 is positioned in the proximal coronary sinus. With the catheter 40 thus positioned, a venogram of the coronary sinus is performed to define the coronary sinus anatomy and diameter. The venogram may be performed in a manner well known in the art wherein a contrast material 44 is injected into the coronary sinus for viewing under fluoroscopy. [0037] After the venogram of the coronary sinus, the circumflex artery is cannulated in a manner well known in the art. An angiogram, also as known in the art, is then performed to define the baseline circumflex/obtuse marginal anatomies. [0038] Next, the distal coronary sinus or great cardiac vein 14 a is cannulated with a catheter 46 which again is inserted through the ostium 13 into the coronary sinus 14 and distally to the great cardiac vein 14 a as shown in FIG. 4. A venogram is then performed on the great cardiac vein 14 a by the injection of the contrast material 44. The venogram is performed in the great cardiac vein to assess the stretched and native diameter of the great cardiac vein at a point where the distal anchor 34 (FIG. 2) of the device 30 will be deployed. [0039] Following the venogram of the great cardiac vein, a catheter 50 having marker bands 52 is deployed in the coronary sinus 14 and great cardiac vein 14 a as illustrated in FIG. 5. The markers 52 are preferably visible under fluoroscopy and are spaced apart by a known distance. This enables the length 21 from the distal great vein to the great vein/coronary sinus junction 23 to be determined and the length 25 from the great vein/coronary sinus junction 23 to the ostium 13 to be determined. [0040] At this point, the anatomy of the circumflex artery and its branches, the great vein, and the coronary sinus are recorded in terms of diameter, shape, and length. This enables the selection of a suitably dimensioned device for implant from a plurality of provided devices each having dimensions corresponding to a respective different set of anatomical features or dimensions. To complete the assessment of the device to be selected, the amount of mitral annulus reduction is estimated. This estimation is based upon the degree of mitral regurgitation, the coronary angiogram, and the venogram measurements. In most cases, a reduction in the mitral annular area will be on the order of 20%-60% as is illustrated, for example, with the deployed device 30 in FIG. 2. [0041] The device 30 along with its deployment system 70 is illustrated in FIG. 6. As shown, the device is in the process of being implanted in the coronary sinus 14/great vein 14 a of the heart 10. Its proximal anchor 36 and distal anchor 34 have not yet been deployed. The deployment system 70 includes an elongated catheter 72, an elongated pusher 74, and a coupling structure 76. The coupling structure is particularly shown and described in copending application Ser. No. 10/331,143, filed Dec. 26, 2002, titled SYSTEM AND METHOD TO EFFECT THE MITRAL VALVE ANNULUS OF A HEART, and which application is owned by the assignee of the present invention and incorporated herein by reference. As disclosed therein, the device 30 is releasably locked to the pusher 74 by the coupling structure 76. [0042] In deploying the device 30, the catheter 72 is first fed into the coronary sinus 14 adjacent the mitral valve annulus 20. The device 30 and pusher 54 at this time are releasably locked together. The device is then loaded into the catheter 72. The pusher 74 follows the device into the catheter 72 and is then advanced along the catheter to push the device 30 distally down the catheter to a predetermined position adjacent the mitral valve annulus 14 at the distal end of the catheter 72. Thereafter, the device is maintained in a stationary position by the pusher 74 as the catheter 72 is partially withdrawn to expose the distal anchor 34. The exposure of the distal anchor 34 may now be confirmed under fluoroscopy. It is then deployed in a manner as fully described in the aforementioned copending application Ser. No. 10/142,637. Once the distal anchor 34 is deployed, the pusher 74 is pulled proximally as shown in FIG. 7 for tightening the device within the coronary sinus and to an extent believed necessary to result in the desired effect on the geometry of the mitral valve annulus 20. During this adjustment process, mitral regurgitation may be monitored and the device tension adjusted to evaluate the effectiveness of the device for optimal results. [0043] Once the device tension is adjusted for optimal results, arterial perfusion of the heart is assessed to determine if the tension on the device has adversely affected arterial perfusion of the heart. Heretofore, arterial perfusion has been assessed during or after procedures performed in the cardiac arterial system, such as after angioplasty or after implantation of a stent in a coronary artery. The assessment for arterial perfusion may be made in a number of different ways as known in the art. For example, the assessment may be made by performing one or more of the following: a coronary angiography, an intravascular ultrasound, a fractional flow reserve analysis, echocardiography, sampling for chemical markers of ischemia or myocardial ischemia detection via electrocardiogram. [0044] Prior to this invention, however, the need to assess arterial perfusion during or after a procedure performed in the cardiac venous system (such as the mitral valve procedure described here) has not been recognized. By assessing both the efficacy of the procedure as well as the procedure's effect on cardiac perfusion, the clinician can maximize the benefit to the patient while minimizing potential harm to the patient. In this mitral valve procedure, therefore, the goal is to maximize arterial perfusion while minimizing mitral valve regurgitation. The desired amount of arterial perfusion and the tolerable amount of mitral valve regurgitation depend upon patient-dependent factors such as the patient's overall health, level of activity and extent of coronary artery disease. [0045] Thus, prior to finalizing deployment of the device 30 in the coronary sinus, arterial perfusion of the patient's heart is assessed. For example, in performing the angiogram, the coronary arteries may be cannulated and injected with a contrast material viewable under fluoroscopy to define the anatomy and lumen diameter of the arterial system prior to deployment of the device in the coronary sinus or elsewhere in the cardiac venous system. After deployment, if the device crosses over a coronary artery and partially compresses the artery, the effect may be detected. While adequacy of arterial flow is a complex determination, the angiogram can help detect critical stenosis of key vessels. [0046] If intravascular ultrasound is used to assess arterial perfusion, an intravascular ultrasound probe may be advanced into a coronary artery to determine the lumen diameter around the location of a device implanted in adjacent regions of the cardiac venous system, such as the coronary sinus. If the lumen of the artery is reduced by placement of the device, the intravascular ultrasound can quantitate the reduction. [0047] As another example, in performing a fractional flow reserve analysis, a pressure wire is used to calculate the difference in pressures between the ascending aorta and the coronary artery. This enables one to detect whether or not significant stenosis exists within a coronary artery or vessel. After administering adenosine to the patient, placing a distal pressure transducer so that it is distal to the device in the coronary sinus would provide feedback regarding whether the placement of the device created significant arterial stenosis. For example, a ratio of distal to proximal pressure less than 0.7 may indicate an unacceptable reduction in arterial perfusion which would lead the clinician to adjust the implanted device. [0048] With respect to echocardiography, when the myocardium experiences ischemia, it has the tendency to compromise contractility. Real-time echocardiography (transthoracic, transesophageal, and intracardiac) may be used as an indirect tool to determine if arterial blood supply is compromised to a sufficient degree to create myocardial ischemia. Dyskinesis, akinesis, hypokinesis, or dyssynchrony are all potential indicators of myocardial ischemia. [0049] Another technique for monitoring arterial perfusion of the heart is to look for chemical markers of ischemia, such as troponin, creatine kinase and other techniques. Yet another technique is to use a doppler flow wire to monitor arterial flow rates. [0050] Lastly, with respect to the detection for myocardial ischemia, an electrocardiogram may be taken from which ST segment changes may be detected. Preferably, the electrocardiogram is a 12-lead electrocardiogram which may also help to localize where the ischemia even occurs. To the extent that a device in the coronary sinus could affect perfusion in the anterior, posterior and lateral segments of a heart, an electrocardiogram could provide indirect evidence of myocardial ischemia. [0051] Once adequate arterial perfusion is confirmed, deployment of the device 30 may be completed. This entails the retraction of the catheter 72 to expose the proximal anchor 36. The proximal anchor 36 may then be deployed as fully described in copending U.S. application Ser. No. 10/142,637. Once the device 30 is fully deployed, the coupling mechanism 76 releases the pusher 74 from the device 30. The pusher 74 and catheter 72 are then retracted from the patient. [0052] With the device 30 now positioned in the heart as illustrated in FIG. 2, the effectiveness of the device may once again be confirmed. Also, it is preferable that another assessment of arterial perfusion be performed at this time to assure that perfusion of the heart has not been compromised. [0053] If, after the device is deployed, additional adjustment is required, the deployment catheter 72 may be advanced into the coronary sinus partially over the proximal anchor to partially recapture it. Then, as fully described in the aforementioned copending application Ser. No. 10/331,143, tension may be imparted on the device for adjusting the device to the anatomy of the heart. If at any point during the procedure it is necessary to recapture one or both of the anchors to reposition or remove the device, the device may be recaptured as fully described in the aforementioned application Ser. No. 10/331,143. Once adequate arterial perfusion and mitral regurgitation reduction or elimination has been confirmed, the coupling structure 76 may uncouple the device from the pusher 74. This permits the deployment system 70 to be withdrawn from the patient. [0054] While particular embodiments of the present invention have been shown and described, modifications may be made, and it is therefore intended in the appended claims to cover all such changes and modifications which fall within the true spirit and scope of the invention.
