[0020]FIG. 1 is a top perspective view of an occlusion device 10. As viewed in FIG. 1, the device 10 comprises a center section 12, proximal and distal fixation devices 14, 30 (each comprised of six arms 16), atraumatic tips 18, an proximal sheet 20, and a distal sheet 22. The proximal and distal fixation devices 14, 30 are attached to the sheets 20, 22 using sutures 28. The proximal and distal fixation devices 14, 30 are connected to the center post 12. One method of connecting the arms 16 to the post 12 is to provide the center post 12 with drill holes through which the arms 16 extend. The atraumatic tips 18 are located at the distal end of each arm 16 and serve to minimize damage to the surrounding tissue. The atraumatic tips 18 provide a place for the sutures 28 to attach the sheets 20, 22 to the proximal and distal fixation devices 14, 30. One method of suturing the sheets 20, 22 to the proximal and distal fixation devices 14, 30 is to provide the atraumatic tips 18 with drill holes through which the sutures 28 pass. In this way, the sheets 20, 22 are sewn to the fixation devices 14, 30 at the atraumatic tips 18. More specifically, the occlusion device 10 is constructed so that the proximal and distal fixation devices 14, 30 are easily collapsible about the center section 12. Due to this construction, the occlusion device 10 can be folded so that the fixation devices 14, 30 are folded in the axial direction. The proximal and distal sheets 20, 22 attached to the proximal and distal fixation devices 14, 30 are flexible, and can likewise collapse as the proximal and distal devices 14, 30 are folded. In addition, the center post 12 further comprises a knob 24. The knob 24 allows for the device 10 to be grasped as it is inserted into the body through the catheter.
[0026]FIGS. 2A through 2D illustrate the method by which the occlusion device 10 is deployed. FIG. 2A is a diagrammatic view of a human heart 30. Visible in FIG. 2A is the right atrium 32, the left atrium 34, the right ventricle 36, the left ventricle 38. The right atrium 32 is separated from the left atrium 34 by a atrial septal wall 40. The right ventricle 36 is separated from the left ventricle 38 by a ventricular septal wall 42. Also visible in FIG. 2A is an atrial septal defect 44 located in the atrial septal wall 40, between the right atrium 32 and left atrium 34 of the heart 30. An atrial septal defect 44 is one example of a cardiac defect that may be occluded using the occlusion device 10.
[0027]FIG. 2B is a more detailed view of the septal wall 40 and the defect 44, shown between the right atrium 32 and the left atrium 34. Also shown is the occlusion device 10 of FIG. 1, a catheter 50, and a delivery forceps 52. As viewed in FIG. 2B, the occlusion device 10 comprises a distal side 54, a proximal side 56, and a center section 12. The occlusion device 10 is being inserted into the septal defect 44 from the catheter 50. The device 10 is tethered to the delivery forceps 52.
[0032]FIG. 2C shows an occlusion device 10 with an articulated center section 12 being inserted into a cardiac defect 44. Shown once again are the defect 44, septal walls 40, catheter 50, and occlusion device 10 comprising a distal side 54, and a proximal side 56. In FIG. 2C, the occlusion device 10 has been further advanced through the catheter 50 to expose the articulated center section 12 comprising a joint 62.
[0034]FIG. 2D shows an occlusion device 10 having an articulated center section 12 that is fully deployed and is occluding a cardiac defect 44. Shown in FIG. 2D is a distal side 54, a proximal side 56, a center post 12, a joint 62, septal walls 40, and a defect 44. The distal side 54 has been properly positioned, the proximal side 56 has been deployed and the device 10 has been released. FIG. 2D demonstrates the ability of an occlusion device 10 having an articulated center section 12 to conform to an irregularly shaped defect 44.
Another important advantage of the present invention is that the articulated center section 12 allows the distal and proximal sides 54, 56 to conform more readily to the contours of the heart 30 after it is deployed, providing a custom fit to a variety of defects. Often, when implanted, an occlusion device 10 is located in an irregularly shaped defect 44. Having an articulated center section 12 allows the occlusion device 12 to fit in a wider variety of defects, despite the shape or size of the defect.
[0039]FIG. 3A is a perspective view of an example of an articulated center section 70 with double articulation. As viewed in FIG. 3A, the center section 70 comprises a right part 72, left part 74, and a center part 76. The left part 74 has a knob 24 located on one end. Both right and left parts 72, 74 have three holes 80 drilled through them. The center section 70 further comprise two joints or hinges 78 on each end of the center part 76. The joints or hinges 78 connect the right and left parts 72, 74 to the center 76 and allow for the right and left parts 72, 74 to rotate relative to the center part 76. The wire arms 16 (FIG. 1) attach to the center section by passing through the holes 80 drilled through the left and right parts 72, 74.
[0043]FIG. 4 is an enlarged side view of one example of an articulated center section 70, showing the section 70 in more detail. The articulated center section 70 is comprised of a right part 72, a left part 74 which has a knob 24, a center part 76, and two joints 116, 118. The center part 76 is comprised of a left sleeve 112 and a right sleeve 114. The left part 74 connects to center section 76 at the left joint 116. The right part 72 connects to the center part 76 at the right joint 118.
[0045]FIG. 5 is an enlarged side view of the left part 74. The left part 74 comprises a ball 120, a first neck 122, a cylindrical body 124, a second neck 126, a knob 24, and three holes 80. As described above, three holes 80 are drilled through the part 74 to allow for attachment of the wire arms 16.
The end ball 120 on one end of the left part 74 is connected to the cylindrical body 124 of the left part 74 at the first neck 122. The knob 24 is located on the other end of the cylindrical body 124 and is connected to the body 124 by a second neck 126. To assist in assembly, discussed in more detail below, the cylindrical body 124 of the left part 124 is preferably smaller in diameter than the ball 120. The knob 24 has a smaller diameter than both the body 124 and the ball 120. For example, the end ball 120 may have a diameter A of about 1.35 millimeters, the cylindrical body 124 may have a diameter B of about 1.2 millimeters, and the knob 24 may have a diameter C of about 1.0 millimeter.
[0048]FIG. 6 is a side view of a right part 72. The right part 72 comprises a ball 130, a first neck 132, a cylindrical body 134, and three holes 80. Once again, three holes 80 are drilled through the part 72 to allow for attachment of the wire arms 16.
The right part 72 is nearly identical to the left part 74 except that it does not require a knob 24 or second neck 86. Because the occlusion device 10 only needs to be graspable at one end, a second knob is unnecessary. To assist in assembly, the cylindrical body 124 of the left part 124 is preferably smaller in diameter than the ball 120. For example, the end ball 130 may have a diameter D of about 1.35 millimeters, and the cylindrical body 134 may have a diameter E of about 1.2 millimeters.
[0050]FIG. 7 is an exploded view of the center section. Shown is a right sleeve 112 and a left sleeve 114. The right sleeve 112 comprises a cuff 140. The cuff 140 is configured to fit inside the left sleeve 114 when the two sleeves are assembled. As shown more clearly on FIG. 8, the two sleeves 112, 114, once assembled, the two sleeves 112, 114 can be permanently attached at the cuff 140, and secured by welding.
[0051]FIG. 8 shows a cross sectional view of an assembled articulated center post., Shown is the left part 74, the right part 72, and the center part 76, which comprises the left sleeve 114, and the right sleeve 112 having a cuff 140. Also shown is a washer 150. Each sleeve has a sleeve opening 152. Also shown are the details of the left and right parts: a knob 24, a second neck 126, first necks 122, 132, cylindrical bodies 124, 134, end balls 120,130, and holes 80. The sleeves 112, 114 have been welded together.
