  • Patent number: 11564620
    Abstract: Biomarkers are collected and used to determine biological propensities of a patient, to determine the efficacy of medical devices, to select and administer therapeutic agents, to select medical devices, to make adjustments to medical devices, and/or to adjust surgical techniques. An apparatus includes a port to draw a biological fluid (e.g., a mist) from a surgical site. The apparatus includes a sensor having a cantilevered beam. The beam includes substances selected to attract certain biomarkers as the fluid is communicated across the beam. The same apparatus or another apparatus is used to administer a therapeutic agent based at least in part on collected biomarker data. The therapeutic agent delivery apparatus may include a device that is also used to create a wound at a surgical site. For instance, a harmonic surgical instrument may be used to both collect biomarkers and administer a therapeutic agent (e.g., gene therapy using sonoporation).

  • Patent number: 11564684
    Abstract: A surgical instrument, operable to compress, staple, and cut tissue, includes a body, a shaft, and an end effector with a pair of jaws. A placement tip that is bent, angled, or curved and extends distally from one of the jaws of the end effector. The placement tip is elastically deformable when the placement tip is subject to a clamping force, such as when the end effector is closed with the jaws in contact or when tissue is clamped between the jaws of the end effector. When the placement tip deflects, relative angles defined in part by the placement tip vary compared to an initial state without the clamping force. Furthermore, a distal end of the placement tip may change position based on the state of deflection of the placement tip in response to the clamping force.
