Patent number: 11564620Abstract: 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).Type: GrantFiled: December 26, 2019Date of Patent: January 31, 2023Assignee: Cilag GmbH InternationalInventors: Jeffrey W. Clymer, Prasanna Malaviya, Donna L. Korvick, Kevin L. Houser, Cory G. Kimball, Frederick E. Shelton, IV, Chester O. Baxter, III, Taylor W. Aronhalt

Patent number: 10433900Abstract: An end effector including a first jaw, a second jaw, a longitudinal slot, and a cutting member is disclosed. The first jaw includes a first lateral side and a second lateral side. At least one of the first jaw and the second jaw is moveable through a range of positions to move the end effector between an open configuration and a fully clamped configuration.

Publication number: 20160128762Abstract: A surgical instrument can comprise an end effector including a plurality of jaws which can be configured to compress tissue therebetween. The end effector can further comprise one or more electrodes which can be configured to direct a flow of electrical current through the tissue in order to heat the tissue and denature collagen and/or other proteins within the tissue. As the tissue cools, the collagen and/or other proteins can renature and thereby seal the tissue. In certain embodiments, the end effector of the surgical instrument can further comprise movable portions which can apply a tension force to the tissue surrounding the tissue being sealed. In various circumstances, the tension force can reduce the over-denaturation, shrinkage, and/or other damage to the surrounding tissue caused by heat flowing from the end effector during the sealing process.Type: ApplicationFiled: January 20, 2016Publication date: May 12, 2016Inventors: Jason L.
