Organ manipulator and positioner and methods of using the same
First Claim
1. A device for manipulating and positioning an organ, said device comprising:
- an inflatable member having an opening passing therethrough and an organ contacting surface;
a positioning element comprising a lumen passing through at least a portion thereof, said positioning element connected to said inflatable member and sealing one end of said opening, wherein an opposite end of said opening remains open and passes through said organ contacting surface, said lumen configured to be coupled to a vacuum source and fluidly communicate with said opening through said inflatable member, wherein said positioning element is configured to position said inflatable member and deliver negative pressure to a surface of the organ via said lumen and said opening, when said organ contacting surface contacts the organ.

Abstract
Devices and methods are provided for manipulating and supporting an organ. The subject devices are characterized by having an inflatable annular member having a central opening and an organ contacting surface, a vacuum distribution element configured to create a diffused vacuum space in the central opening, and a positioning element having a lumen coupled to a vacuum source and to the inflatable annular member. The subject devices are suitable for use in a variety of surgical approaches and, as such, may be configured to be inserted into a patient'"'"'s chest cavity through a sheath. Methods are also provided for using the subject devices, where the order of the methods may be altered. Also provided are systems and kits for manipulating and positioning an organ.

20. A method of manipulating and positioning an organ, said method comprising:
-
introducing a deflated member of a device into a body cavity; inflating the member to an inflated configuration; contacting the organ with the inflated member; applying a vacuum to the organ through an opening that passes through an organ contacting surface of the inflated member, while maintaining the inflated member in the inflated configuration, to create an intimate engagement between the organ and the inflated member; and moving the inflated member, to manipulate or position the organ. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)

34. A device for manipulating and positioning an organ, said device comprising:
-
an inflatable member having an opening passing therethrough and an organ contacting portion surrounding a distal end of said opening, wherein said opening passes through said organ contacting portion; a first lumen connected to a proximal end of said opening and forming a fluid seal with said proximal end, said first lumen configured to deliver negative pressure through said opening; a second lumen fluidly connected to said inflatable member and not fluidly connected with said opening; and a positioning element connected to said inflatable member. - View Dependent Claims (35, 36)

37. A device for manipulating and positioning an organ, said device comprising:
-
an inflatable member having an opening passing therethrough and an organ contacting surface; a positioning element comprising a lumen passing through at least a portion thereof, said positioning element connected to said inflatable member and sealing one end of said opening, said lumen configured to be coupled to a vacuum source and fluidly communicate with said opening through said inflatable member, wherein said positioning element is configured to position said inflatable member and deliver negative pressure to a surface of the organ via said lumen and said opening, when said organ contacting surface contacts the organ; and an attachment element interconnecting said inflatable member and said positioning element, wherein said attachment element fluidly seals a connection of said lumen with said opening and allows limited freedom of movement of said inflatable member with respect to said positioning element, such that when said inflatable member is engaged with the surface of the organ, normal movements of the organ are permitted by movement of said inflatable member with respect to said positioning element; wherein said attachment element comprises a flexible linkage mechanism.

39. A device for manipulating and positioning an organ, said device comprising:
-
an inflatable member having an opening passing therethrough and an organ contacting surface; a positioning element comprising a lumen passing through at least a portion thereof, said positioning element connected to said inflatable member and sealing one end of said opening, said lumen configured to be coupled to a vacuum source and fluidly conmunicate with said opening through said inflatable member, wherein said positioning element is configured to position said inflatable member and deliver negative pressure to a surface of the organ via said lumen and said opening, when said organ contacting surface contacts the organ; and an attachment element interconnecting said inflatable member and said positioning element, wherein said attachment element fluidly seals a connection of said lumen with said opening and allows limited freedom of movement of said inflatable member with respect to said positioning element, such that when said inflatable member is engaged with the surface of the organ, normal movements of the organ are permitted by movement of said inflatable member with respect to said positioning element; wherein said attachment element is configured to allow vertical and lateral movement of said inflatable member, when engaged with the organ, where the organ is a beating heart, and when said positioning element is held relatively stationary, so as not to reduce negative effects on hemodynamics of the beating heart.
