Patent number: 9186130Abstract: Improved methods and devices for performing an endoscopic surgery are provided. Systems are taught for operatively treating gastrointestinal disorders endoscopically in a stable, yet dynamic operative environment, and in a minimally-invasive manner. Such systems include, for example, an endoscopic surgical suite. The surgical suite can have a reversibly-expandable retractor that expands to provide a stable, operative environment within a subject. The expansion can be asymmetric around a stabilizer subsystem to maximize space for a tool and an endoscope to each be maneuvered independently to visualize a target tissue and treat the target tissue from outside the patient in a minimally invasive manner.Type: GrantFiled: April 12, 2013Date of Patent: November 17, 2015Assignee: Macroplata Inc.Inventors: Gregory Piskun, John To, Mariel Fabro, Brian Tang, Sergey Kantsevoy

Patent number: 9072513Abstract: Devices and methods used in termination of a tissue tightening procedure are described. Termination includes the cinching of a tether to tighten the tissue, locking the tether to maintain tension, and cutting excess tether. In procedures involving anchors secured to the tissue, the tether is coupled to the anchors and the tissue is tightened via tension applied to the anchors by cinching the tether. In general, the devices and methods can be used in minimally invasive surgical procedures, and can be applied through small incisions or intravascularly. A method for tightening tissue by fixedly coupling a first anchor to a tether and slidably coupling a second anchor to the tether, securing both anchors to the tissue, applying tension to the tether intravascularly, fixedly coupling the tether to the second anchor, and cutting the tether is described. The tissue to be tightened can comprise heart tissue, in particular heart valve annulus tissue.Type: GrantFiled: August 6, 2008Date of Patent: July 7, 2015Assignee: Guided Delivery Systems Inc.Inventors: John To, Niel F. Starksen, Tenny C. Calhoun, Brian Tang

Publication number: 20150157192Abstract: Improved methods and devices for performing an endoscopic surgery including a system for performing minimally invasive procedures including a flexible catheter having a first lumen, a first flexible tube positioned in the first lumen, and a second flexible tube positioned in the first lumen. The first lumen defines a first space configured and dimensioned to receive an endoscope. The first flexible tube and second flexible tube are fixed at a proximal portion and configured to float within the first lumen of the catheter. First and second flexible guides are slidably positioned within the first and second flexible tubes and dimensioned to receive a first instrument for axial movement therein, the first and second flexible guides movable to an angled position with respect to a longitudinal axis.Type: ApplicationFiled: February 14, 2015Publication date: June 11, 2015Applicant: Macroplata, Inc.Inventors: Gregory Piskun, Jeffrey Peter Radziunas, John To, Mariel Fabro, Brian Tang, Sergey Kantsevoy

Patent number: 8870867Abstract: Embodiments of the technology provide an articulable electrosurgical instrument and methods of performing electrosurgery with an articulating capability. The electrosurgical instrument includes an elongated shaft having an end effector associated with a distal end thereof that is able to deliver energy to a target tissue site. An articulable joint is positioned between that shaft and the end effector. Articulation of the articulable joint is controlled by a stabilizable articulation actuator, which may include a rotatably stabilizable disk residing within a well. The end effector may take the form of forceps including an upper and a lower jaw; the jaws are configured to grasp target tissue and to deliver energy, such as radiofrequency energy. In some of these instruments, the end effector is adapted to seal tissue by the application of radiofrequency energy, and then to cut through the sealed tissue portion.Type: GrantFiled: March 23, 2011Date of Patent: October 28, 2014Assignee: Aesculap AGInventors: Erik Walberg, Lawrence Kerver, Brian Tang, Brandon Loudermilk

Patent number: 8795298Abstract: Devices, methods, and kits for tensioning tethers during a tissue modification procedure are described. In some variations, a tether coupled to anchors embedded in tissue may be tensioned to provide a cinching effect that tightens or compresses the tissue by bringing two pieces or sections of the tissue together. In certain variations, the tether may then be locked (e.g., to maintain the tension), and/or excess tether may be severed. The devices, methods, and/or kits may be used, for example, in minimally invasive procedures.Type: GrantFiled: October 9, 2009Date of Patent: August 5, 2014Assignee: Guided Delivery Systems Inc.Inventors: Jonathan D.
