Publication number: 20230346204Abstract: Sheaths that may be used with endoscopes, and in particular, robotic endoscopes and/or telescoping endoscopes, as well as method of using these sheaths to prevent cross-contamination between patients and contamination of the endoscope are described. These sheaths include both an outer sheath for covering the outside of the endoscope and one or more inner sheaths for covering a lumen of the endoscope, and are configured so as not to interfere with the flexibility or operation of the endoscope. These sheaths may reduce or eliminate the need for endoscope cleaning.Type: ApplicationFiled: May 30, 2023Publication date: November 2, 2023Inventors: Alexander Q. TILSON, Thomas HSIU, Niklas J.

Publication number: 20230346205Abstract: A port adapter manifold may couple to one or more multi-lumen catheters to form sealed individual connections between each lumen of the multi-lumen catheter, allowing controlled access to each lumen. Described herein are apparatuses and methods, including in particular endoscope sheath systems, that include a port adapter manifold that is configured to couple to a proximal end region of a multi-lumen catheter to form a plurality of sealed ports in fluid communication with each lumen of the multi-lumen catheter.Type: ApplicationFiled: May 30, 2023Publication date: November 2, 2023Inventors: Alexander Q.

Publication number: 20080183038Abstract: A biological navigation device that can be attached or integrated with an elongated element, such as a colonoscope, is disclosed. The device can be used for navigation through a biological lumen. The device can have an everting tube controllably tearable substantially in the direction of the long axis of the device. The elongated element can be deployed through a channel formed in the inner virtual space of the channel extending along the long axis.Type: ApplicationFiled: January 31, 2008Publication date: July 31, 2008Applicant: Loma Vista Medical, Inc.Inventors: Alexander Quillin Tilson, Eugene Duval

Publication number: 20080071289Abstract: Two surgical instruments are inserted through a guide tube. The surgical instruments exit at an intermediate position of the guide tube and are oriented to be substantially parallel to the guide tube's longitudinal axis as they exit. A stereoscopic image capture component is on the guide tube between the intermediate position and the guide tube's distal end. The image capture component's field of view is generally perpendicular to the guide tube's longitudinal axis. The surgical instruments and the guide tube are telemanipulatively controlled.Type: ApplicationFiled: June 13, 2007Publication date: March 20, 2008Applicant: Intuitive Surgical, Inc.Inventors: Thomas Cooper, David Rosa, David Larkin, Matthew Williams, Eugene Duval

Publication number: 20080071290Abstract: A surgical instrument extends through a guide tube and exits at an intermediate position of the guide tube. The instrument includes a parallel motion mechanism that changes the position of a distal end of the surgical instrument without changing the orientation of the distal end. An image capture component is at the distal end of the guide tube, and a joint allows the image capture component to move while the intermediate position remains stationary. The configuration allows a cross section of the guide tube to be oblong. In some aspects, a joint for the image capture component is placed between exit ports for surgical instruments, which allows the guide tube cross section to be further reduced.Type: ApplicationFiled: June 13, 2007Publication date: March 20, 2008Applicant: Intuitive Surgical, Inc.Inventors: David Larkin, Thomas Cooper, David Shafer, David Rosa, Matthew Williams, Eugene Duval

Publication number: 20080065110Abstract: A minimally invasive surgical instrument includes a U-turn mechanism that transmits actuating forces around a U-turn. The U-turn mechanism is coupled between segments of the instrument and has a bend radius that is smaller than flexible arms having a similar cross section diameter. The actuating forces transmitted by the U-turn mechanism are used to move distal components of the instrument, such as an end effector and a wrist mechanism.Type: ApplicationFiled: June 13, 2007Publication date: March 13, 2008Applicant: Intuitive Surgical INC.Inventors: Eugene Duval, David Shafer, Bruce Schena
