Publication number: 20140276936Abstract: An exemplary drive apparatus is disclosed having a roller assembly configured to impart axial motion to the elongate member along a first continuous surface configured to maintain contact with the elongate member during axial motion. The drive apparatus may further include a roller support configured to rotate the roller assembly, thereby imparting rotational motion to the elongate member. The roller support may be configured to rotate the roller assembly about a second continuous surface configured to maintain contact with the roller support during rotational motion. Moreover, the roller assembly and roller support may be configured to impart axial and rotational motion independently of one another, such that a first one of the roller assembly and the roller support imparts their associated motion regardless of a presence or absence of motion by the other of the roller assembly and the roller support.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Applicant: Hansen Medical, Inc.Inventors: Arkady Kokish, Francis Macnamara

Publication number: 20140148759Abstract: A steerable catheter comprises a flexible catheter body including a proximal shaft section and a distal articulating section, a proximal steering interface coupled to the proximal shaft section, and at least one hollow stiffening member extending through the proximal shaft section. The stiffening member(s) is more rigid than the proximal shaft section and is laterally offset from a geometric cross-sectional center of the proximal shaft section. The steerable catheter further comprises circumferentially spaced lumens extending through the distal articulating section, and pullwires extending through the stiffening member(s) in the proximal shaft section and the respective lumens in the distal articulating section. Each of the pullwires has a distal end that terminates in the catheter body distal to the distal articulating section and a proximal end that terminates in the steering interface. The steering interface is manipulatable to selectively tension the pullwires to bend the distal articulating section.Type: ApplicationFiled: November 28, 2012Publication date: May 29, 2014Applicant: HANSEN MEDICAL, INC.Inventors: Francis Macnamara, Joseph Bogusky, Arkady Kokish, Enrique Romo, Jason Hsu, Kiran Murthy, Leena Kadakia, Helen Truong

Publication number: 20050075538Abstract: An endoscopic imaging system includes a reusable control cabinet having a number of actuators that control the orientation of a lightweight endoscope that is connectable thereto. The endoscope is used with a single patient and is then disposed. The endoscope includes an illumination mechanism, an image sensor, and an elongate shaft having one or more lumens located therein. An articulation joint at the distal end of the endoscope allows the distal end to be oriented by the actuators in the control cabinet. The endoscope is coated with a hydrophilic coating that reduces its coefficient of friction and because it is lightweight, requires less force to advance it to a desired location within a patient.Type: ApplicationFiled: March 29, 2004Publication date: April 7, 2005Inventors: Michael Banik, Dennis Boulais, Lucien Couvillon, Albert Chin, Frank Anderson, Francis Macnamara, Stephen Fantone, Daniel Braunstein, Daniel Orband, Michael Saber, Ian Hunter, Patsy Coppola, Andrew Kirouac, Richard Clark, Richard Wiesman, Timothy Mason, Neil Mehta, Amna Elona Greaves
