  • Patent number: 8591459
    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: 8574238
    Abstract: A cannula has a flange and a body with slots extending through the entire flange and into the body. The cannula may also have a longitudinal slot extending its entire length. An obturator used with the cannula may also have a longitudinal slot extending along its length. A surgical method using these instruments includes separating lengths of suture and managing the suture by placing lengths of suture in the slots in the cannula. The cannula and obturator may be used after suture is already in place by placing the suture in the longitudinal slots and then introducing the cannula and obturator to the tissue defect site. The cannula may also be used to deliver a therapeutic implant to the tissue defect site. The instruments and method may be used in mensical surgery.

  • Publication number: 20130023875
    Abstract: 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.

  • Patent number: 8349255
    Abstract: A tissue processing system includes a tray and a processing component. The processing component has teeth configured to dice, mince, and mix the tissue in the tray. In some versions, teeth of a rotary member mesh with teeth of a stationary member, such that the tissue is ground between the meshing teeth. The rotary member may be moved in an orbital path relative to the stationary member. In some versions, the teeth of two rotary members mesh together, and the rotary members are rotated in opposite directions to grind the tissue. The rotary members may also be alternatingly moved up and down to perform initial dicing on the tissue. Once the tissue has been processed, the tissue may then be used in a therapeutic manner, such as by being incorporated with a scaffold and then implanted in the same patient from whom the tissue was originally harvested.

  • Patent number: 8286899
    Abstract: A tissue dicing and separation device comprises a housing having an interior that receives tissue for dicing and separation. The device includes a blade assembly connected to a motor and solenoid. The solenoid reciprocates the blade assembly while the motor clocks the blade assembly during each reciprocation cycle. This reciprocating and clocking action of the blade assembly dices and/or minces the tissue. The housing is filled with a fluid and then the blade assembly is continuously rotated to create a vortex within the housing. The vortex causes the diced tissue particles to separate by particle size. Outlets at different positions along the housing permit withdrawal of a slurry of fluid and tissue particles with the tissue particles having a desired size range. The obtained slurry may be used in conjunction with a fistula plug treatment device and method.

  • Publication number: 20120259353
    Abstract: A surgical instrument that may include a housing, a transducer engaged with the housing which can produce vibrations, and an end-effector engaged with the transducer. The surgical instrument can include an adjustable sheath extending from the housing where the sheath is movable relative to the distal tip of the end-effector and where the distance between the distal tip of the sheath and the distal tip of the end-effector can enable the sheath to act as a depth stop. The sheath can be adjusted such that, when the distal tip of the sheath contacts the tissue or bone being incised, the surgeon can determine that the appropriate depth of the incision has been reached. In other embodiments, the end-effector can be moved with respect to the sheath to adjust the distance between the distal tip of the end-effector and the distal tip of the sheath.

  • Publication number: 20120191015
    Abstract: Surgical instruments for use in mapping tissue defects include telescoping rulers and tubes. One of the instruments has a pointed anchoring tip for piercing tissue near the site of the defect. Another instrument has a hook for catching an anatomical landmark. Measuring portions of the rulers of both instruments include distance indicia so that a coordinate system can be established for mapping the location of the defect or of an implant at the defect site. The coordinate system can be re-established at a later time using the same fixation point for the anchoring tip and the same landmark for the hook to evaluate the clinical effects of the treatment selected. The method of using the instrument set is also described.
