Patent number: 8758225Abstract: An adapter for endoscopic treatments has a fiber constraint device that is set at a desired maximum fiber retraction distance, and provides a physical barrier to prevent excessive fiber retraction into the endoscope. The restricted retraction prevents the fiber from firing within the endoscope, thus avoiding expensive damage to both the endoscope and fiber. This benefits the patient with potentially shorter treatment time and less exposure to anesthesia. The adapter also limits maximum extension of fibers. Limiting maximum extension protects the fiber tip and avoids patient complications. The adapter is securely attached to the optical fiber with a connecting means. When using directionally radiating fiber tips, fiber orientation can be defined and the fiber can be rotated relative to the initial angular position of the fiber tip.Type: GrantFiled: July 28, 2008Date of Patent: June 24, 2014Assignee: Biolitec Pharma Marketing LtdInventors: Brian Foley, William LeBlanc

The tip may be detachable for replacement. An endoscope extends through the shaft and is connected with a monitor to enable the surgeon to visually observe the area being treated. In a preferred form a light means extends through the shaft to illuminate the area being treated, and in a further preferred form a conduit extends through the shaft to convey a fluid to flush the area being treated. In a further embodiment, two endoscopes are associated with the probe.Type: ApplicationFiled: December 27, 2012Publication date: May 22, 2014Inventor: Avery M. Jackson, III

Patent number: 8727966Abstract: A medical device such as an endoscope, a laparoscope, or other device including an entry guide uses outriggers or arms that are mounted on the distal end of the entry guide and rotationally deployed to provide separation of instruments when the entry guide reaches a work site. Deployment can be implemented with as few as one cable or actuator to operate the arms. This mechanism may achieve working separation in a short axial length without complicating instrument channels that may be used for other instruments introduced through the entry guide.Type: GrantFiled: March 31, 2008Date of Patent: May 20, 2014Assignee: Intuitive Surgical Operations, Inc.Inventor: Theodore W. Rogers

Patent number: 8727967Abstract: An instrument for use with an endoscope may include an elongate section configured to move exterior to the endoscope. The elongate section may include a distal end and a proximal end. The instrument may also include an end effector attached to the distal end of the elongate section, and an actuation device attached to the proximal end of the elongate section. The actuation device may be configured to operate the end effector. The instrument may also include a guiding member coupled to the elongate section. The guiding member may be configured to be coupled to an external surface of the endoscope to permit the guiding member to move longitudinally relative to the endoscope. The guiding member may be coupled to the elongate section such that the end effector may extend past a distal end of the endoscope and move in a transverse direction independent of the movement of the distal end of the endoscope.Type: GrantFiled: July 16, 2009Date of Patent: May 20, 2014Assignee: Boston Scientific Scimed, Inc.Inventor: Barry Weitzner

Patent number: 8715281Abstract: This treatment device for endoscope is used for cutting body tissue while the treatment device is retractably projected from a catheter. The treatment device includes: a control wire inserted into the catheter; and a cutting electrode mounted at the distal end of the control wire with the cutting electrode being imparted a bent configuration in advance. The cutting electrode elastically deforms in a state where the cutting electrode is retracted into the catheter, thereby assuming such a shape as to resemble the configuration of the catheter.Type: GrantFiled: March 7, 2007Date of Patent: May 6, 2014Assignee: Olympus Medical Systems Corp.Inventors: David E. Barlow, Kunihide Kaji, Takayuki Suzuki, Masatoshi Sato, Kensuke Hayashi, Takayasu Mikkaichi, Junji Shiono

Publication number: 20140121457Abstract: Provided is a suturing apparatus for endoscope capable of suturing an opening of a wound, with an endoscope inserted into cavity of a digestive tract, to the same extent as the surgical operation. The suturing apparatus includes a front arm 11, a rear arm 12, arm moving means 13 for causing the front arm 11 and the rear arm 12 to move closer to or away from each other, and rocking means for relatively rocking the front arm 11 and the rear arm 12. The rear arm 12 includes a needle-like member 14 provided on a surface on a side of the front arm 11 so that an axial direction thereof becomes parallel with a direction in which the front arm 11 and the rear arm 12 are moved closer to or away from each other. The front arm 11 is provided with a housing space 16 capable of housing a tip of the needle-like member 14 when the front arm 11 and the rear arm 12 are moved closer to each other. Each of the housing spaces houses an engagement member 21 capable of being engaged with the needle-like member 14.Type: ApplicationFiled: January 23, 2012Publication date: May 1, 2014Applicant: NATIONAL UNIVERSITY CORPORATION KAGAWA UNIVERSITYInventors: Hirohito Mori, Tatsurou Sugitani, Yoshihito Momose

Publication number: 20140114126Abstract: A device for releasable coupling of a first medical tool to a second medical tool. The device may include an elongate member having a first end and a second end. The first end may be configured to be secured to a portion of the first medical tool, and the second end may be secured to a coupling sleeve. The coupling sleeve defines a lumen that may receive a portion of the second medical tool.Type: ApplicationFiled: October 18, 2013Publication date: April 24, 2014Applicant: Boston Scientific Scimed, Inc.Inventor: Russell P. DRESHER

Patent number: 8702596Abstract: A valve apparatus device provides surgical instruments with sealable access to an inlet port of an endoscope instrument channel. The valve has a hollow body with a distal end that releasably attaches to the inlet port, and a flexible diaphragm seal dividing the body into a proximal chamber and a distal chamber. An instrument opening extends through the diaphragm seal for the passage of instruments therethrough, and connects the chambers together. The diaphragm seal is configured to seal with a surgical instrument inserted into the instrument opening. At least one fluid transfer member is provided to fluidly interconnect the proximal chamber to the distal chamber when the surgical instrument is sealed within the instrument opening.Type: GrantFiled: September 16, 2011Date of Patent: April 22, 2014Assignee: United States Endoscopy Group, Inc.Inventors: Christopher J. Kaye, Gary E. Mann

Patent number: 8696548Abstract: Systems and methods employing a small gauge steerable catheter (30) including a locatable guide (32) with a sheath (40), particularly as an enhancement to a bronchoscope (14). A typical procedure is as follows. The location of a target in a reference coordinate system is detected or imported. The catheter (30) is navigated to the target which tracking the distal tip (34) of the guide (32) in the reference coordinate system. Insertion of the catheter is typically via a working channel of a convention bronchoscope. Once the tip of the catheter is positioned at the target, the guide (32) is withdrawn, leaving the sheath (40) secured in place. The sheath (40) is then used as a guide channel to direct a medical tool to target.Type: GrantFiled: June 9, 2011Date of Patent: April 15, 2014Assignee: Covidien LPInventor: Pinhas Gilboa
