SYSTEMS AND METHODS FOR DIRECTING INSTRUMENTS TO VARYING POSITIONS AT THE DISTAL END OF A GUIDE TUBE
Publication number: 20130225926Abstract: Described herein are various systems and methods for directing endoscopy instruments to varying positions at a target site. In one aspect, at least one instrument channel has multiple exit points at the distal end of the guide tube, and the position of an instrument delivered through the channel may be switched between the different exit points. In another aspect, an instrument channel splits into multiple branches at the distal end of the guide tube, and the position of an instrument at the target site may be changed by selectively directing the instrument into a different channel branch. In yet another aspect, the guide tube, or a portion thereof, may be rotated to reposition an instrument at the target site. The capability of changing the instrument positions during a procedure would enable a physician to examine or treat multiple target sites within an operative field, without necessitating the full retraction of the instruments or the guide tube from the operative field.Type: ApplicationFiled: February 27, 2013Publication date: August 29, 2013Applicant: Boston Scientific Scimed, Inc.Inventors: Paul Smith, Katie L.

Patent number: 8517923Abstract: Methods and apparatus for accessing and treating regions of the body are disclosed herein. Using an endoscopic device having an automatically controllable proximal portion and a selectively steerable distal portion, the device generally may be advanced into the body through an opening. The distal portion is selectively steered to assume a selected curve along a desired path within the body which avoids contact with tissue while the proximal portion is automatically controlled to assume the selected curve of the distal portion. The endoscopic device can then be used for accessing various regions of the body which are typically difficult to access and treat through conventional surgical techniques because the device is unconstrained by “straight-line” requirements. Various applications can include accessing regions of the brain, thoracic cavity, including regions within the heart, peritoneal cavity, etc., which are difficult to reach using conventional surgical procedures.Type: GrantFiled: May 19, 2004Date of Patent: August 27, 2013Assignee: Intuitive Surgical Operations, Inc.Inventors: Amir Belson, Robert Matthew Ohline

Sufficient force is applied to clear blood between the surface and the wall and clear the field of view of the imaging assembly. The catheter is manipulated to locate the coronary sinus, whereupon the localization member is advanced into the coronary sinus.Type: GrantFiled: August 15, 2011Date of Patent: May 14, 2013Assignee: The Board of Directors of the Leland Stanford, Jr. UniversityInventors: Nicholas J.

Systems and methods for directing instruments to varying positions at the distal end of a guide tube
Patent number: 8425406Abstract: Described herein are various systems and methods for directing endoscopy instruments to varying positions at a target site. In one aspect, at least one instrument channel has multiple exit points at the distal end of the guide tube, and the position of an instrument delivered through the channel may be switched between the different exit points. In another aspect, an instrument channel splits into multiple branches at the distal end of the guide tube, and the position of an instrument at the target site may be changed by selectively directing the instrument into a different channel branch. In yet another aspect, the guide tube, or a portion thereof, may be rotated to reposition an instrument at the target site. The capability of changing the instrument positions during a procedure would enable a physician to examine or treat multiple target sites within an operative field, without necessitating the full retraction of the instruments or the guide tube from the operative field.Type: GrantFiled: December 17, 2009Date of Patent: April 23, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Paul J. Smith, Katie Krueger, Barry Weitzner, Andy Campbell -
Publication number: 20130096383Abstract: An attachment unit rotates in directions around a longitudinal axis with respect to an insertion main body when rotary drive force is transmitted from a drive force transmission unit provided to an insertion section, and allows propulsive force in one of directions parallel to the longitudinal axis to act on the insertion section by rotating in contact with a paries. The attachment unit includes a fin portion which is spirally extended along the longitudinal axis and whose dimension from the longitudinal axis to an outer peripheral end vary in accordance with how external force different from the propulsive force acts in the directions parallel to the longitudinal axis in a state that the attachment unit does not rotate with respect to the insertion main body.Type: ApplicationFiled: October 9, 2012Publication date: April 18, 2013Applicant: OLYMPUS MEDICAL SYSTEMS CORP.Inventor: Olympus Medical Systems Corp.
