US 6682474 B2Abstract
This application is a continuation of copending U.S. application Ser. No. 09/634,043, which was filed on Aug. 8, 2000, and which claims priority to U.S. Application Serial No. 60/188,282, which was filed on Mar. 10, 2000.
One requirement is to provide a slight elastic compression to the epicardial surface of the left ventricular wall. The device should allow expansion and contraction of the heart, but continue to apply gentle elastic compression to the left ventricle. This would reduce circumferential and longitudinal wall tension, thereby improving efficiency, lowering energy expenditure, reducing neurohormonal activation, encouraging favorable cellular changes, and stabilizing the dimensions of the heart. This mechanical action is often referred to as “myocardial sparing.” The device should effect myocardial sparing without limiting the motion or the dimensions of the heart. Nor should it actively change the shape of the heart by pulling it or squeezing it. In fact, imposing a rigid barrier to limit distension or to squeeze the heart can be potentially dangerous. Shabetai in The Role of the Pericardium in the Pathophysiology of Heart Failure notes that the pericardium exerts 3-4 mm Hg of pressure against the heart. Cardiac function can be adversely affected with just a slight increase in pericardial constraint. For example, cardiac tamponade begins to be seen with pericardial pressures as low as 5-10 mm Hg.
Alternatively, as illustrated in FIGS. 10 and 11, the rows or strips 20 of hinges 6 can be interlocked (FIGS. 10a and 10 b) or interwoven (FIGS. 11a and 11 b). To interlock strips 20 of hinges 6, the central portion 8 of a hinge 6 from a first row, or strip 20, is placed between the arms 10 of a hinge from a second row. This placement of a “hinge within a hinge” occurs for one or more hinges 6 in a first strip 20, relative to the hinges in a second strip. To interweave strips 20 of hinges 6, as illustrated in FIGS. 11a and 11 b, the strips 20 are configured such that one arm 10 of a first hinge 6 from a first strip 20 lies under the central portion 8 of a second hinge from a second strip, while the other arm 10 of the first hinge 6 lies over the central portion 8 of the second hinge from the second strip.
An important difference between the decoupled hinge harness construction of the preferred embodiment and a knitted fabric harness, or cardiac “sock,” is the hinge harness's ability to closely track changes in sphericity of the underlying heart, whether the heart is healthy or diseased. This has been demonstrated experimentally by using an inflated latex bladder, which simulates a heart in its expansion and contraction. First, relative changes in sphericity of the bladder were measured. Note that sphericity is defined as diameter (D) divided by length (L): sphericity = diameter length This relationship is illustrated in FIG. 12, which shows the diameter (D) of the heart in the transverse dimension and the length (L) of the heart in the longitudinal direction. The results of this experiment are illustrated in FIG. 13. When the bladder was inflated alone (i.e., without the presence of a harness), it generated a sphericity-versus-volume curve that is illustrated as the middle curve in FIG. 13. When a polyester knit “sock” was applied to the bladder, there was a great increase in sphericity as the volume of the bladder increased, as illustrated by the top curve of FIG. 13. In contrast, when the elastic hinge harness 4 of the preferred embodiment was applied to the bladder, the sphericity-versus-volume curve more closely matched that of the unencumbered bladder alone. The elastic hinge harness sphericity curve is illustrated as the bottom curve in FIG. 13. Thus, the elastic hinge harness of the preferred embodiment closely tracks changes in sphericity over a range of volumes of the underlying structure, in this case a latex bladder. The nonforeshortening elastic hinge harness 4 had little impact on the sphericity index as bladder volume increased. In fact, the sphericity index values were slightly lower than for the bladder alone. In contrast, the presence of the knitted sock significantly increased the sphericity of the bladder as its volume was increased. This demonstrates the potential importance of the nonforeshortening elastic feature of the harness with respect to its application to the human heart. The harness has the ability either (1) to “track” (i.e., minimally alter) changes in sphericity of one or both ventricles throughout systole and diastole; or (2) to progressively decrease the sphericity index of the heart, relative to an unencumbered heart (i.e., without the harness), as diastole proceeds, whether the heart is healthy or in congestive failure.
Delivery of the harness 4 can be accomplished through conventional cardiothoracic surgical techniques through a median sternotomy. Alternatively, the harness 4 may be delivered through minimally invasive surgical access to the thoracic cavity, as illustrated in FIG. 19. A delivery device 36 may be inserted into the thoracic cavity 34 between the patient's ribs to gain direct access to the heart 2. Preferably, such a minimally invasive procedure is accomplished on a beating heart, without the use of cardiopulmonary bypass. Access to the heart can be created with conventional surgical approaches. The pericardium may be opened completely, or a small incision can be made in the pericardium (pericardiotomy) to allow the delivery system 36 access to the heart 2. The delivery system 36 of the disclosed embodiments comprises an integrated unit of several components, as illustrated in FIGS. 20a and 20 b. Preferably, there is a releasable suction device, such as a suction cup 38, at the distal tip of the delivery device 36. This negative pressure suction cup 38 is used to hold the apex of the heart 2. Negative pressure can be applied to the cup 38 using a syringe or other vacuum device. A negative pressure lock can be achieved through a one-way valve, stopcock, or a tubing clamp. The suction cup 38, advantageously formed of a biocompatible material, is preferably stiff to prevent any negative pressure loss through heart manipulation. this provides traction by which the harness 4 can be pushed forward onto the heart 2. In addition, the suction cup 38 can be used to lift the heart 2 to facilitate advancement of the harness 4 or allow visualization and surgical manipulation of the posterior side of the heart 2. After secure purchase of the apex of the heart 2 is achieved, the harness 4, which is collapsed within the body 46 of the delivery device 36, is advanced distally toward the heart 2 by actuating fingers 40. The harness 4 can be inverted (i.e., turned inside-out) ahead of time, to allow it to unroll, or evert as it advances over the surface of the heart 2. In this discussion, the term “evert” means turning right-side-in, i.e., reversing an inverting process. After the harness 4 is advanced into place, the suction is released and the delivery system 36 is released from the harness 4 and heart 2.
