This document describes medical systems that have features for initiating operational settings during a start-up process. For example, this document describes heart-lung machine systems that are programmed and integrated with features that perform semi-autonomous start-up procedures.

Heart-lung machine with semi-autonomous initiation mode

A vessel harvesting system removes a target vessel from a patient for use as a bypass. An elongated harvesting instrument inserts into a body along a path of a target vessel which includes at least one side branch. The harvesting instrument includes a cutter for applying thermal energy to sever and cauterize the side branch. An endoscopic camera captures visible-light images from a distal tip of the instrument within a dissected tunnel around the target vessel. A thermal camera captures thermograms coinciding with the visible-light images to characterize a temperature present at respective surfaces in the tunnel. An image processor (e.g., an electronic controller) renders a video stream including the visible-light images and an overlay depicting the temperatures present on at least some of the respective surfaces when applying the thermal energy. A display presenting the video stream and overlay to a user can be an augmented-reality display.

Endoscopic vessel harvesting with thermal management and augmented reality display

This document describes devices used during surgical procedures for the treatment of heart conditions. For example, this document describes technology to monitor the operations of a heart-lung machine and then shows associated read outs on a head-worn display in order to provide an augmented-reality presentation. For example, various sensors on and around a heart-lung machine, patient, and/or extracorporeal circuit can monitor the operations of the procedure using the heart-lung machine.
