FIG. 4 is a cross-sectional view of the delivery device of FIG. 3 taken along the line 4—4 of FIG. 3;
FIGS. 6–14 show additional steps in placement of the cardiac support device of FIG. 1 onto the heart; and
FIG. 17 is a cross-sectional view of the delivery device of FIG. 16, taken along the line 17—17 of FIG. 16; and
The second tube 102, in the embodiment shown, further includes a plurality of grooves 114 extending at least partially between the first end 106 and second end 108. In preferred embodiments, the plurality of grooves 114 extend completely between the first end 106 and second end 108. There can be any number of grooves 114. In the preferred embodiment illustrated, there is an equal number of grooves 114 as there are strands in the string system 52. In FIG. 4, grooves 114 are shown as four individual, and equally spaced-apart channels 116, 117, 118, and 119. The channels 116–119 form open volumes 122 between the internal surface 80 of the first tube 72 and the second tube 102. In the preferred embodiment illustrated, each channel 116–119 holds one of the strands of the string system 52, when the cardiac support device 30 is loaded within the device 70 for placement onto heart 42. The strands in the string system 52 can be folded multiple times in order to fit within the appropriate channel 116–119.
When the device 70 is loaded with the cardiac support device 30 for placement of the jacket 32 onto the heart 42, the apex strand 62 extends through an opening in the end cap 82, and the jacket 32 is collapsed into a bundle 126. Each of the strands of the string system 52 is directed out through the first end 106 of the second tube 102. Each strand 54, 56, 58, and 60 is individually inserted into a respective one of the channels 116, 117, 118, 119. The channels 116–119 function, for among other reasons, to hold the slack of each of the strands 54, 56, 58, 60 and help to prevent tangling of the strands in the device 70. Each of the strands 54, 56, 58, 60 extends from the respective channel 116–119 and is held by a respective slit 96, 97, 98, 99. The device 70 is then ready to be used to operably place the jacket 32 onto the heart 42.
In reference now to FIGS. 16–18, an alternate embodiment of the device 70 is illustrated. Device 70, shown in FIGS. 16–18, differs from the embodiment of FIGS. 3 and 4 in that there is a single tube 72′. Tube 72′ differs from tube 72 in FIG. 3 in that it includes channels 116–119 molded there within. The tube 72′ can be conveniently manufactured by extrusion, with a tubular wall 74′ extruded along with the channels 116–119. As with the embodiment of FIGS. 3 and 4, the channels 116–119 in FIGS. 16–18 define open volumes 122 for accommodating one of the strands of the string system 52. In the example embodiment illustrated, each of the channels 116–119 extends completely between the oblique opening 84 and the opposite end 78. In FIG. 17, it can be seen how each of the channels 116–119 is completely enclosed, to form closed tubes or lumens 166, 167, 168, 169 having opposite open ends at oblique opening 84 and opposite end 78. The strings in the string system 52 are shown positioned within the open volumes 122 in a respective channel 116–119. The strings in the string system can be folded multiple times in order to fit within the appropriate channel 116–119.
The insertion end 76 of the tube 72′ also defines holding structure 90 for temporarily and selectively securing the string system 52 to the device 70. In the FIG. 3 embodiment, the holding structure 90 includes slots 92 formed as cut or notch 94 in the wall 74 at the insertion end and along the oblique opening 84. In the embodiment of FIG. 16, the holding structure 90 is also in the form of slots 92, but is defined as cut or notch 94′ along the inside surface 170 of the tubular wall 74′. Each cut or notch 94′ extends from the open end at the oblique opening 84 partially down the inside surface 170 of each lumen 166–169 and in communication with the open volume 122 of each of the channels 116–119. Each of the strings of the string system 52 is held within a respective notch 94′. In the embodiment shown in FIG. 16, there are four notches 94′, depicted as slits 96′, 97′, 98′, and 99′.
In the implementation illustrated in FIG. 16, the slit 96′ holds the first anterior strand 54; the slit 97′ holds the first posterior strand 58; the slit 98′ holds the second posterior strand 60; and the slit 99′ holds the second anterior strand 56. FIG. 18 illustrates one example technique for holding the strands of the string system 52 in their respective channels 116–119. Each strand is parked within its respective slit 96′–99′ and looped back over itself to form a grasping loop 174, 175, 176, 177. Each of the strands of the string system 52, in the embodiment illustrated, is shown to be oriented within device 70 to have a respective grasping loop 174–177. The grasping loops 174–177 can be grasped and manipulated by surgical tools, such as forceps and hooks in order to deploy the jacket 32 from the device 70 and onto the heart 42. This is described further below.
In reference now to FIGS. 5–14, a method in accordance with principles of this disclosure for applying the cardiac support device 30 is illustrated schematically. FIG. 5 shows in general a thoracic region 130 of a mammal, e.g. a human 132, having heart 42. The heart 42 is shown in dashed lines to indicate that it is below the exterior surface of the thoracic region 130.
