Patent number: 9883879Abstract: An apparatus and method for effecting at least one anatomical structure of a body including at least one first arrangement structured to be at least partially inserted into the body and including an opening, at least one third arrangement configured to increase and/or decrease a size of the opening by a motion thereof in a first direction, and at least one second arrangement coupled to the third arrangement(s). When the anatomical structure(s) is/are inserted in the opening and is pressed on by the second arrangement(s), a first motion of the third arrangement(s) toward the anatomical structure(s) in the first direction is reduced and/or terminated while a second motion of the second arrangement(s) either (i) remains at least approximately the same, and/or (ii) is reduced to a lesser extent than that of the first motion.Type: GrantFiled: February 13, 2015Date of Patent: February 6, 2018Assignee: COVIDIEN LPInventors: Gregory Piskun, Patrick Gutelius, Oleg Shikhman

Patent number: 9833250Abstract: An apparatus for treating hemorrhoids including a first member having a proximal portion, a distal portion and a window formed therein to receive tissue. A third member is operably connected to the second member and movable between a first position and a second position, the third member having a clamping surface movable to the second position to provide a clamping force on tissue received through the window. Movement of the second member in a distal direction moves the third member in the distal direction toward the second position, the third member movable in a distal direction until such movement is limited due to contact and compression of tissue within the window, the second member continuing movement in the distal direction after movement of the third member in the distal direction has been limited.Type: GrantFiled: December 16, 2012Date of Patent: December 5, 2017Assignee: COVIDIEN LPInventors: Gregory Piskun, Patrick Gutelius, Oleg Shikhman

Publication number: 20170325662Abstract: 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: ApplicationFiled: August 2, 2017Publication date: November 16, 2017Inventors: Gregory Piskun, John To, Mariel Fabro, Brian Tang, Sergey Kantsevoy

Patent number: 9539027Abstract: Laparoscopic instruments and trocars are provided for performing laparoscopic procedures entirely through the umbilicus. A generally C-shaped trocar provides increased work space between the hands of the surgeon as well as S-shaped laparoscopic instruments placed through the trocar when laparoscopic instrument-trocar units are placed through the umbilicus. In order to facilitate retraction of intra-abdominal structures during a laparoscopic procedure, an angulated needle and thread with either one- or two sharp ends is provided. Alternatively, an inflatable unit having at least one generally C-shaped trocar incorporated within the unit's walls can be placed through the umbilicus following a single incision. Generally S-shaped laparoscopic instruments may be placed through the generally C-shaped trocars to facilitate access to intra-abdominal structures.Type: GrantFiled: March 23, 2015Date of Patent: January 10, 2017Assignee: Covidien LPInventor: Gregory Piskun
