Patent number: 8864654Abstract: The foregoing application describes a system and method of performing a minimally invasive surgical operation. More specifically, the invention involves the use of disposable cannula and slender dilators of variable lengths, which incorporate a source of illumination to carry light to a surgical site and video capabilities for capturing and displaying images from a CMOS or CCD camera device. According to one embodiment, fiber optics run semi-circumferentially or along walls of the cannula/dilator and terminate at about a centimeter from the distal end of the cannula/dilator, thereby preventing illumination from “bottoming out” at the floor of the incision. According to one alternate embodiment, the light fibers may be fashioned in an annulus around one or more camera chips to provide illumination and video of the surgical site.Type: GrantFiled: April 20, 2011Date of Patent: October 21, 2014Inventors: Jeffrey Kleiner, Jeffrey Adair, Kevin Wiggins

Patent number: 8852085Abstract: A surgical system includes a first instrument defining a first channel and a second instrument receivable by the first channel. The second instrument defines a second channel. A valve coupled to the first instrument controls fluid flow through the first channel, such that impedance of fluid flow through the first channel is substantially the same without the second instrument received in the first channel and with the first channel partially blocked by the second instrument. In another aspect, a surgical apparatus includes an outer member and an inner member received within the outer member to define a first channel therebetween. The inner member houses an optical lens and defines a second channel for receiving a surgical instrument. The first and second channels are configured such that a pump having an inflow rate of up to about 0.7 L/min connected to the second channel can maintain fluid pressure inside an organ.Type: GrantFiled: April 11, 2013Date of Patent: October 7, 2014Assignee: Smith & Nephew, Inc.Inventors: Cemal Shener-Irmakoglu, Christopher R. Newell, Petter Hedstrom, Kenneth W. Krause

Publication number: 20140275788Abstract: An electrosurgical system may include a medical delivery device and an electrosurgical device to perform an electrosurgical procedure. The electrosurgical device may have a monopolar configuration. An outer surface of the medical delivery device may include a conductive portion that is part of a return path for a bipolar configuration. Current may be supplied through an active member of the electrosurgical device to perform the procedure. After passing through tissue, the current may be drawn to the electrode portion of the medical delivery device to complete the circuit.Type: ApplicationFiled: March 13, 2014Publication date: September 18, 2014Applicant: Cook Medical Technologies LLCInventor: Tyler Evans McLawhorn

Patent number: 8821389Abstract: An endoscopic aspiration device is mounted on a manipulating head of an endoscope, from which an elongated insertion rod member is extended forward, the endoscopic aspiration device being composed of a valve casing which is mounted on the manipulation head in communication with an aspiration passage running through the insertion rod member, and a valve assembly unit including a valve member, a valve guide member and a connector member attached to the valve guide member to communicate same with a proximal aspiration passage on the side of a suction source. The valve member is put in a sliding displacement along the valve guide member to bring the aspiration passage into and out of communication with the proximal aspiration passage on the side of a suction source. The valve guide member is coupled with the valve casing through a coupling mechanism which permits to turn the valve assembly unit on and relative to the manipulating head.Type: GrantFiled: January 31, 2013Date of Patent: September 2, 2014Assignee: FUJIFILM CorporationInventor: Kenji Yamane

Patent number: 8808170Abstract: Embodiments of the invention provide devices and associated methods for use when performing endoscopic procedures. According to one aspect, a sheath positionable within a working channel of an endoscopic device, and adapted for receiving one or more instruments, is provided. The sheath can include a first channel and a second channel, the first channel and the second channel extending at least partially along a length of the sheath, wherein at least one of the first channel or the second channel includes an open edge open along at least part of the length of the respective channel.Type: GrantFiled: March 1, 2011Date of Patent: August 19, 2014Inventor: Mark A. Stern
