Patent number: 7935051Abstract: A system for accessing a surgical target site and related methods, involving an initial distraction system for creating an initial distraction corridor, and an assembly capable of distracting from the initial distraction corridor to a secondary distraction corridor and thereafter sequentially receiving a plurality of retractor blades for retracting from the secondary distraction corridor to thereby create an operative corridor to the surgical target site, both of which may be equipped with one or more electrodes for use in detecting the existence of (and optionally the distance and/or direction to) neural structures before, during, and after the establishment of an operative corridor to a surgical target site.Type: GrantFiled: April 22, 2009Date of Patent: May 3, 2011Assignee: NuVasive, Inc.Inventors: Patrick Miles, Scot Martinelli, Eric Finley, James Gharib, Allen Farquhar, Norbert Kaula, Jeffrey Blewett, Goretti Medeiros, legal representative

Publication number: 20110092810Abstract: The present disclosure provides for systems and methods for Nested Cannula configuration. Nested Cannula systems include a plurality of telescoping, pre-shaped tubes configured and dimensioned to reach target locations within a particular anatomical region. A three dimensional image is read for the particular anatomical region and structure in question. A series of arcs are generated between a point of the anatomical region and a target location, ensuring collision-free motion for each of the tubes at each specific diameter. The target location is determined based upon the medical procedure being performed and the location and orientation in six degrees of freedom of the anatomical structure in question. The series of arcs are used to configure and dimension the plurality of tubes. The Nested Cannula system is adapted to reach relatively small and complex target locations, such as to deliver photodynamic therapy, balloon angioplasty or BronchoAlveolar Lavage.Type: ApplicationFiled: June 12, 2009Publication date: April 21, 2011Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventor: Karen Irene Trovato

Publication number: 20110077500Abstract: Systems and related methods for measuring pelvic organ prolapse are disclosed. A plurality of positioning devices, such as RFID tags, ultrasound reflectors or magnetic field sensors, which may be active or passive, and which are preferably disposable, are set at predetermined positions within the patient and their relative positions recorded with one or more corresponding external receiving devices fixed to the patient while the patient is in a relaxed state. The patient is then instructed to perform an action (such as a valsalva maneuver) that causes the positioning devices to move and their movement relative to their initial recorded positions is measured.Type: ApplicationFiled: September 29, 2010Publication date: March 31, 2011Inventor: Khashayar Shakiba

Patent number: 7892174Abstract: A surgical access system includes retractor for creating an access path between an incision site and a surgical site. The retractor includes a frame having a base member and a pair of generally curved rails extending therefrom. A tubular member is coupled to the frame and includes first and second blade portions that are capable of relative movement with respect to each other by movement on the curved rails. A method of inserting the retractor into a patient includes inserting a guide rod over a guide wire, locating an obturator in the retractor, inserting the obturator and retractor over the guide rod, and removing both the guide rod and obturator to leave the retractor in the body to provide the access path.Type: GrantFiled: January 17, 2007Date of Patent: February 22, 2011Assignee: Zimmer Spine, Inc.Inventors: Hugh D. Hestad, Rajesh Dwarakanath, Daniel Robbins, Deborah Lynn Hoch

Publication number: 20110021879Abstract: Devices, methods, and systems provide a surgical access device comprising an internal retractor device integrated with or coupled to a body wall or wound retractor. The wound retractor retracts an opening in a body wall into a body cavity, while the internal retractor permits a user to control the positions of internal structures within the body cavity, thereby permitting a user to define a surgical field. Embodiments of the internal retractor are adjustable.Type: ApplicationFiled: July 21, 2010Publication date: January 27, 2011Applicant: Applied Medical Resources CorporationInventors: Charles C. Hart, Gary M. Johnson, Eric Nguyen, Edward D. Pingleton, Kenni Pravongviengkham, Ghassan Sakakine, Serene Wachli, John R. Brustad, Olivia J. Tran

Publication number: 20110004067Abstract: A surgical retractor includes a plurality of blade assemblies interconnected by a plurality of racks. One or more of the blade assemblies is movable along a rack to selectively expand the retractor. At least one of the blade assemblies includes a blade that is rotatably connected to the blade assembly and that is rotatable independent of other blades of the retractor.Type: ApplicationFiled: July 1, 2010Publication date: January 6, 2011Inventors: Connie Marchek, William Frasier, Anne Kothari, Sara Dziedzic, Holly Brideau, Thomas J.
