Patent number: 8007432Abstract: Devices and methods useful for manipulating tools at a surgical site are disclosed. In one exemplary embodiment, an accessory device is provided and can include an insertion member and a control wire. The insertion member can have a lumen for receiving a tool therethrough, such as an endoscope. The control wire can be coupled to the insertion member and have a distal portion extending distally from the insertion member and be adapted to receive and to manipulate a tool extending through the insertion member. The control wire can have a wide variety of configurations, and in certain exemplary embodiments the control wire can be slidably received in one or more control wire lumens formed through the insertion member. In use, the control wire can be manipulated, for example by axially sliding the control wire in one or more control wire lumens to control a tool.Type: GrantFiled: January 26, 2007Date of Patent: August 30, 2011Assignee: Ethicon Endo-Surgery, Inc.Inventors: Omar J Vakharia, David Stefanchik, James T Spivey

Patent number: 8007504Abstract: A method and apparatus for functionally occluding the lumen of the left atrial appendage (LAA) is provided. Access to the LAA is through an epicardial approach. The devices function to capture the LAA through various non-invasive means. After capturing the LAA with the devices and methods provided, a clamping device is preferably disposed about the base of the appendage. In certain embodiments, the appendage remains viable subsequent to the functional occlusion of the lumen.Type: GrantFiled: March 24, 2009Date of Patent: August 30, 2011Assignee: University of Pittsburgh of The Commonwealth System of Higher EducationInventors: Marco Zenati, David S. Schwartzman, Mark J. Gartner, Daniel T. McKeel
