A surgical instrument for use on a patient. A tube assembly comprises an outer tube having a curved region, an inner tube disposed within the outer tube and comprising a single lumen, and a handle coupled to the outer tube. A viewing assembly is disposed within the single lumen. An actuation assembly is coupled to the inner tube and configured to steer the viewing assembly. The handle and the actuation assembly are complimentarily arranged such that the outer tube is positionable and the viewing assembly is steerable a user grasping the tube assembly with a single hand. The single lumen may define an irrigation flow path in communication with a fluid source and provide pressurized irrigation flow. An interior tube may be provided comprising an articulating region configured to articulate between a substantially curved condition and a substantially straight condition. Methods of manipulating an instrument are also disclosed.

An articulating tracheoscope control device, a laryngeal mask airway (LMA) device, and an articulating tracheoscope control device and LMA device combination system, that can control precise movement of a distal end of a tracheoscope with a patient's larynx within an angular range of at least 180 degrees and can lock the distal end of the tracheoscope in any desired position within the patient's larynx such that managing the tracheoscope during a tracheostomy procedure is not required in order to monitor the tracheostomy procedure.

Techniques for multi-mode imaging device control include determining, by a controller, if an orientational mode command or a translational mode command is entered; in response to determining that the orientational mode command is entered, constraining, by the controller, movement of an imaging device so that a focal point of the imaging device moves along a concave virtual surface in response to translational movement of one or more input devices; and in response to determining that the translational mode command is entered, causing, by the controller, translational movement of the imaging device in a three-dimensional space in response to the translational movement of the one or more input devices.

Example embodiments relate to endoscopic systems. The system includes first and second main bodies. First main body includes first end section, which includes a first anchor assembly and first proximal portion. First anchor assembly includes first and second expandable members and first negative pressure opening. First and second expandable members are each configured to transition between a non-expanded configuration and an expanded configuration. First negative pressure opening is configured to apply negative pressure. First proximal portion is secured to the first anchor assembly. First proximal portion includes a bendable portion configured to selectively move the first anchor assembly in a plurality of directions. Second main body includes first and second end sections and main cavity. First end section of second main body includes a second anchor assembly, which includes third and fourth expandable members and second negative pressure opening. Second negative pressure opening is configured to apply a negative pressure.

An articulating shaft for a steerable catheter system includes a tubular body having a longitudinal central axis and at least one main lumen with a distal end and a proximal end. The shaft further includes at least one wire support element forming at least one wire lumen for supporting at least one actuating wire, the main lumen and the wire lumen are integrally formed in an extrusion part having a uniform hardness in an axial and a radial direction. A plurality of removed sections or cuts of the shaft extend in a radial direction and are distanced from each other in an axial direction.

An endoscope (1) having a handle with a handle housing (2) and an insertion tube (3) extending from said handle (2) and terminating in a tip part (4) at the distal end of the endoscope (1). A working channel and having a distal end and a proximal end extends within the insertion tube (3). The endoscope further comprises motion transfer means (53, 54) extending within said working channel and adapted to operate a tool (55) at the exit port of the tip part (4) in response to the activation of an operating member (22). The working channel comprises a generally tubular working channel wall. The distal working channel end comprises an exit port at the tip part (4) at the distal end of the endoscope (1). The proximal working channel end comprises an end sealing means accommodated within the handle housing (2). An entry port is provided between the distal working channel end and the proximal working channel end.
