Abstract

The invention provides devices and methods for performing less-invasive surgical procedures within an organ or vessel. In an exemplary embodiment, the invention provides a method of closed-chest surgical intervention within an internal cavity of a patient'"'"'s heart or great vessel. According to the method, the patient'"'"'s heart is arrested and cardiopulmonary bypass is established. A scope extending through a percutaneous intercostal penetration in the patient'"'"'s chest is used to view an internal portion of the patient'"'"'s chest. An internal penetration is formed in a wall of the heart or great vessel using cutting means introduced through a percutaneous penetration in an intercostal space in the patient'"'"'s chest. An interventional tool is then introduced, usually through a cannula positioned in a percutaneous intercostal penetration. The interventional tool is inserted through the internal penetration in the heart or great vessel to perform a surgical procedure within the internal cavity under visualization by means of the scope. In a preferred embodiment, a cutting tool is introduced into the patient'"'"'s left atrium from a right portion of the patient'"'"'s chest to remove the patient'"'"'s mitral valve. A replacement valve is then introduced through an intercostal space in the right portion of the chest and through the internal penetration in the heart, and the replacement valve is attached in the mitral valve position.

Claims

organizer means at the proximal end of the cannula body for retaining a plurality of sutures extending through the lumen from the body cavity in spaced apart positions outside of the body cavity.

58. The cannula system of claim 57 wherein the cannula body is configured for positioning in an intercostal space in the patient'"'"'s chest.

59. The cannula system of claim 57 wherein the organizer means comprises a first organizing ring having an interior passage and a plurality of suture retaining means circumferentially spaced about the interior passage.

60. The cannula system of claim 59 wherein the first organizing ring is fixed to the proximal end of the cannula body with the interior passage aligned with the lumen.

61. The cannula system of claim 59 wherein the suture retaining means comprise a plurality of slots in the first organizing ring circumferentially spaced about the interior passage.

62. The cannula system of claim 60 further comprising means at the proximal end of the cannula body for maintaining the sutures in tension.

63. The cannula system of claim 62 wherein the means for maintaining the sutures in tension comprises a second organizing ring spaced apart from the first organizing ring, the second organizing ring having an interior passage and a plurality of means circumferentially spaced about the interior passage for holding the sutures in tension.

64. The cannula system of claim 63 wherein the means for holding the sutures in tension comprise slits in the second organizing ring for frictionally engaging the sutures.

65. The cannula system of claim 62 wherein the means for maintaining the sutures in tension comprises slits in the first organizing ring for frictionally engaging the sutures.

66. The cannula system of claim 58 further comprising means for holding a replacement valve outside the chest in proximity to the organizer means, whereby a suture extending from the body cavity through the lumen in the cannula may be applied to the replacement valve and secured in the organizer means.

67. The cannula system of claim 66 wherein the lumen is configured to facilitate introduction of the replacement valve therethrough into the body cavity.

68-84. -84. (canceled)

85. A cannula system to facilitate surgical intervention in a patient'"'"'s body cavity, the cannula system comprising:

a cannula body having a distal end, a proximal end, and a lumen therebetween, the lumen being configured for introduction of surgical instruments therethrough; and

a suture organizer configured to retain a plurality of sutures extending through the lumen from the body cavity in spaced apart positions outside of the body cavity.
