Terumo had one patents in metaverse during Q2 2024. Terumo Corp’s vessel harvesting system utilizes an elongated harvesting instrument with a cutter to remove a target vessel for use as a bypass. The instrument applies thermal energy to sever and cauterize side branches, while an endoscopic camera and thermal camera capture images and thermograms to characterize temperatures in the dissected tunnel. An image processor renders a video stream with visible-light images and temperature overlays, which can be displayed on an augmented-reality display for user visualization.

Application: Endoscopic vessel harvesting with thermal management and augmented reality display (Patent ID: US20240206704A1)
The vessel harvesting system described in the patent by Terumo Corp involves an elongated harvesting instrument that can be inserted into a patient's body to remove a target vessel for use as a bypass. The instrument includes a cutter that applies thermal energy to sever and cauterize side branches of the target vessel. An endoscopic camera captures visible-light images from the instrument's distal tip within a dissected tunnel around the vessel, while a thermal camera captures thermograms to characterize temperatures in the tunnel. An image processor renders a video stream with visible-light images and an overlay showing temperatures on surfaces when thermal energy is applied, with the display presenting this information to the user, potentially through an augmented-reality display.
The system includes various features such as a color-coded overlay representing temperature magnitudes, the ability to identify the target vessel and side branches for temperature depiction, and cutting indicators to guide the cutter to a favorable location for severing side branches while limiting heat load on the target vessel. The image processor can also accumulate heat exposure on the vessel, display warnings if exposure exceeds a threshold, provide diameter indicators for side branches, determine target energy for severing based on branch diameter, and render energy indicators accordingly. Additionally, the display can be an augmented-reality display worn by the user, enhancing the visualization and guidance provided during the vessel harvesting process.
