Examples relate to apparatuses, methods and computer programs for controlling a microscope system, and to a corresponding microscope system. An apparatus for controlling a microscope system comprises an interface for communicating with a camera module. The camera module is suitable for providing camera image data of a head of a user of the microscope system. The apparatus comprises a processing module configured to obtain the camera image data from the camera module via the interface. The processing module is configured to process the camera image data to determine information on an angular orientation of the head of the user relative to a display of the microscope system. The processing module is configured to provide a control signal for a robotic adjustment system of the microscope system based on the information on the angular orientation of the head of the user.

The invention relates to a valvulotome comprising a catheter tube (4) and an expandable basket (5) with cutting elements (7), wherein the catheter tube (4) being designed to accommodate within itself the expandable basket (5) in a non-expanded state, wherein the basket (5) is fixed to the distal end of a wire element (3) extending in the catheter tube (4) and the basket (5) distally comprises an atraumatically configured resilient tip (8).

Peripheral retinal OCT can be used to generate peripheral retinal OCT images allowing for the peripheral retina to be viewed. A peripheral retinal vision system can determine that a set of fiducial markers is in a field-of-view of at least one camera and record positional data comprising a contact lens position and angle with respect to an OCT imaging system having OCT scanning mirrors in a first position. The system can determine whether a retinal layer is in an OCT scan captured while the set of fiducial markers is in the field-of-view of the at least one camera and the OCT scanning minors are in the first position; and for an OCT scan having he retinal layer and being captured while the set of fiducial markers is in the field-of-view of the at least one camera and the OCT scanning minors are in the first position, store that OCT scan.

An array stabilizer for a surgical system includes a pair of arms configured to extend alongside opposite sides of a portion of an array adapter, which is attachable to a rotational instrument in a manner such that the rotational instrument is rotatable about a central axis relative to the array adapter. The array adapter is configured to extend from another component of the surgical system, such that at least one of the arms of the array adapter is configured to resist rotation of the array adapter about the central axis relative to such component as the rotational instrument rotates. The array stabilizer is either rigidly integrated with such component or is coupled to such component via a coupling device.

A tracking apparatus for tracking a bone of a patient limb is provided. The tracking apparatus includes a body configured to couple to the patient limb. The body includes first and second arms each including an exterior and opposing interior surface and opposing sides connecting the exterior and interior surfaces. The tracking apparatus also includes a wing portion extending from one of the sides of the first or second arm, the wing portion sharing the interior surface of the first or second arm. The tracking apparatus also includes one or more ultrasonic sensors coupled to the interior surface of the body and the interior surface of wing portion, the one or more ultrasonic sensor being configured to transmit ultrasonic waves to and receive ultrasonic waves from the bone. The tracking apparatus also includes one or more trackable elements coupled to the body and the wing portion.

Systems and methods for cardiac pacing are provided, where a pacing lead is placed at or near the bundle of His. A method for pacing a heart of a patient comprises: introducing a sheath to vasculature of the patient; steering the sheath within a coronary sinus in the heart to lodge a distal end of the sheath to a target location proximal to the bundle of His above a septum separating a left ventricle and a right ventricle of the heart; advancing a pacing lead through a lumen of the sheath to the target location; coupling the pacing lead to cardiac tissue at the target location; removing the sheath; and electrically pacing the bundle of His using the pacing lead.

Provided are systems and methods for registration of location sensors. In one aspect, a system includes an instrument and a processor configured to provide a first set of commands to drive the instrument along a first branch of the luminal network, the first branch being outside a path to a target within a model. The processor is also configured to track a set of one or more registration parameters during the driving of the instrument along the first branch and determine that the set of registration parameters satisfy a registration criterion. The processor is further configured to determine a registration between a location sensor coordinate system and a model coordinate system based on location data received from a set of location sensors during the driving of the instrument along the first branch and a second branch.

Method and contact lens (3) for measuring a subject's three dimensional eye movement including torsional movement. A video camera (1) is provided for recording an image of the subject's eye (2). The contact lens (3) is provided for placement over the subject's eye (2). The contact lens (3) comprises one or more markers (3a,3b) that are detectable by the video camera (1) and are positioned at a lateral offset (D) with respect to a central part (3p) of the contact lens (3). The one or more markers (3a,3b) are configured for detecting torsional rotation (R) of the subject's eye (2) around a line of sight axis (C) of the subject's eye (2) by using the video camera (1) to track a position of the one or more markers (3a,3b).

An embodiment includes a system comprising: a catheter; an optic fiber having a long axis and a short axis that is orthogonal to the long axis; first and second radiopaque elements coupled to the optic fiber; a first wire coupled to the optic fiber and extending from the first radiopaque element to the second radiopaque element; a fluid; wherein (a)(i) the first wire wraps at least partially around an exterior surface of the optic fiber; (a)(ii) an outer diameter of the first wire and an outer diameter of the optic fiber are collectively less than an inner diameter of the catheter, and (a)(iii) the first wire is configured to center the optic fiber within the catheter within a plane orthogonal to the long axis.
