Abstract: A surgical tool harvests power from a robotic surgical system having one or more robotic manipulators when a housing of the surgical tool is installed within a carriage of one of the robotic manipulators. The surgical tool harvests power via inductive coupling between an inductor of the surgical tool and a corresponding inductor of the carriage. The surgical tool may include an indicator that provides a user with an indication of remaining life of the surgical tool. The indicator may be an LED indicator that is illuminated with power generated via the inductive coupling. The indicator may also be an electro-chromic indicator that changes color when exposed to power generated via the inductive coupling. The indicator may also be a photo-chromic indicator that changes color when exposed to light from a light source powered via the inductive coupling.

Abstract: A system, method, and apparatus for guiding an astigmatism correction procedure on an eye of a patient are disclosed. An example apparatus include a photosensor configured to record a pre-operative still image of an ocular target surgical site of the patient. The apparatus also includes a real-time, multidimensional visualization module configured to produce a real-time multidimensional visualization of the ocular target surgical site during an astigmatism correction procedure. The apparatus further includes a data processor configured to determine a virtual indicium that includes data for guiding the astigmatism correction procedure. The data processor uses the pre-operative still image to align the virtual indicium with the multidimensional visualization such that the virtual indicium is rotationally accurate. The data processor then displays the multidimensional visualization of the ocular target surgical site in conjunction with the virtual indicium.

Abstract: Embodiments hereof relate to methods of delivering a valve prosthesis to an annulus of a native valve of a heart, the native valve having chordae tendineae. A chordae management catheter is positioned within a ventricle of the heart, the chordae management catheter having a displacement component at a distal end thereof. The displacement component has an annular shape and defines a central lumen therethrough. The displacement component is radially expanded to push chordae tendineae within the ventricle radially outward.

The valve delivery system is advanced through the central lumen of the radially expanded displacement component towards the annulus of the native valve of the heart. The valve prosthesis is deployed into apposition with the annulus of the native valve.
