Patent number: 9055965Abstract: Sinusitis and other disorders of the ear, nose and throat are diagnosed and/or treated using minimally invasive approaches with flexible or rigid instruments. Various methods and devices are used for remodeling or changing the shape, size or configuration of a sinus ostium or duct or other anatomical structure in the ear, nose or throat; implanting a device, cells or tissues; removing matter from the ear, nose or throat; delivering diagnostic or therapeutic substances or performing other diagnostic or therapeutic procedures. Introducing devices (e.g., guide catheters, tubes, guidewires, elongate probes, other elongate members) may be used to facilitate insertion of working devices (e.g. catheters e.g. balloon catheters, guidewires, tissue cutting or remodeling devices, devices for implanting elements like stents, electrosurgical devices, energy emitting devices, devices for delivering diagnostic or therapeutic agents, substance delivery implants, scopes etc.Type: GrantFiled: March 22, 2010Date of Patent: June 16, 2015Assignee: Acclarent, Inc.Inventors: John Y. Chang, Joshua Makower, Julia D. Vrany, John H. Morriss, Ketan P. Muni, Isaac J. Kim, Hung Ha, William M. Facteau, Amrish Jayprakash Walke

Publication number: 20150148596Abstract: A surgical instrument (10, 100) configured to facilitate gripping and manual adjustment by a left-handed or righted-handed user. The surgical instrument includes a rod (11) having a first end (12a) attachable to a working end (13, 113) of the instrument via a mount (16). The rod has a second end (12b) coupled to a handle (14) having rotational directionality for gripping by a first hand of the user. The handle is rotatable about the rod so as to allow the user to adjust an angular displacement of the user's finger relative to the working end, and a locking member (20, 146) prevents rotation of the handle relative to the rod when the beveled indent is optimally located relative to the working end.Type: ApplicationFiled: May 19, 2013Publication date: May 28, 2015Inventor: Eliot Robert Gitman

Patent number: 9039603Abstract: A propulsion apparatus for an endoscope includes a propulsion assembly for mounting on a tip device of the endoscope, for propulsion in a body cavity. First and second wire devices are disposed to extend from the tip device in a proximal direction, having a coil winding, for rotating to drive the propulsion assembly. First and second motors are connected with proximal ends of respectively the first and second wire devices, for rotating the first and second wire devices. A timer is actuated if a speed difference between rotational speeds of the first and second motors becomes equal to or more than a reference speed value, for measuring an elapsed time. A break detector detects breakage of the first wire device if the elapsed time becomes equal to or longer than a predetermined time. A controller controls the first and second motors in response to an output of the break detector.Type: GrantFiled: January 25, 2013Date of Patent: May 26, 2015Assignee: FUJIFILM CorporationInventors: Tsuyoshi Ashida, Takayuki Nakamura, Nobuyuki Torisawa, Takumi Dejima, Naoyuki Morita
