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 Ser. 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 neurohornional 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.
FIGS. 26A-26D are schematic illustrations of a “flower petal” embodiment of the cardiac delivery device.
FIG. 1 illustrates a manmmalian heart 2 with the cardiac harness 4 applied to it. In this illustration, the cardiac harness surrounds both ventricles, from apex to base. Note that the hinges are relatively small in this illustrated embodiment, but in other preferred embodiments, the hinges can be larger.
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 26, 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.
sphericity=diameter/length
Various designs incorporating decoupled hinges 6 are possible. The hinges 6 can wrap continuously around both ventricles or just around the left ventricle or right ventricle. The harness 4 can have a seam for size adjustment, or it can be of a one-size-fits-all design. A Nitinol harness can be provided presized to fit the dimensions of a patient's heart. Alternatively, the harness components can be provided in a kit that a surgeon can custom-assemble in the operating room, based on sizing information gained before or at the time of surgery. A kit can consist of modular components that can be assembled quickly. The use of hinge strips 20 that are ring-shaped and of varying diameters and stiffness is one possibility. The surgeon can interlock hinges 6 between adjacent hinge strips 20 in order to couple the strips 20, as illustrated in FIG. 10b. Precise sizing can be facilitated by using a belt buckle or adhesive fastener (e.g., a hook-and-loop fastener, such as Velcro™) type of design, as illustrated in FIGS. 18a and 18 b. FIGS. 18a and 18 b illustrate the harness 4 wrapped around the heart 2, with a leading flap 32 that integrates an adhesive strip, such as Velcro™, for securing the harness 4 onto the heart 2. Such a design is not readily achievable using the knitted sock of previous designs.
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.
FIGS. 26a-26 d illustrate another embodiment of the delivery device, in which the actuating fingers 40 of the device form a loop or “flower petal” configuration. The actuating fingers 40 are withdrawn within the body 46 of the delivery device in FIG. 26a. FIGS. 26b and 26 c show a progressive advancement of the actuating fingers 40 distally from the body 46 of the delivery device. As the fingers 40 advance, they expand outwardly into a larger loop or flower petal configuration. FIG. 26d is an en face view of the delivery device body 46 and the flower-petal-shaped actuating fingers 40.
