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).

Use of biomarkers and therapeutic agents with surgical devices

A surgical instrument is disclosed comprising a housing, a transducer supported within the housing, an end-effector engaged with the transducer, and a clamp including a jaw member movably supported relative to the end-effector between an open position and a closed position. The transducer is configured to produce vibrations. The end-effector defines an axis and a distal tip. The distal tip is movable relative to the axis by vibrations produced by the transducer. The end-effector is configured to be detached from the transducer. The transducer is configured to receive a different end-effector.

Surgical instruments

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. The longitudinal slot extends intermediate a proximal portion and a distal portion. The longitudinal slot transects the first jaw between the first lateral side and the second lateral side and extends distally beyond a portion of the second jaw. The cutting member is movable along the longitudinal slot. The first jaw is expandable laterally relative to the longitudinal slot to apply a tensile force to tissue clamped between the first jaw and the second jaw when the end effector is in the fully clamped configuration.

Surgical instruments for tensioning tissue

A surgical instrument is disclosed. The surgical instrument can include an end effector, a shaft, and a handle. The handle can include a trigger assembly. The trigger assembly can include a first trigger and a second trigger, which are movable as a nested unit during a first actuation of the trigger assembly to affect a first surgical function. The second trigger can be movable away from the first trigger after the first actuation of the trigger assembly and can be movable toward the first trigger during a second actuation of the trigger assembly to affect a second surgical function.

Surgical instruments comprising a trigger assembly

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 further 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 be set such that the sheath can 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 in order to adjust the distance between the distal tip of the end-effector and the distal tip of the sheath.

An end effector of a surgical instrument may generally comprise a blade, and a clamp arm assembly comprising a clamp arm movable between an open position and a closed position relative to the blade, and at least one camming member rotationally attached to the clamp arm, wherein the at least one camming member is configured to rotate relative to the blade as the clamp arm moves from the open position to the closed position.

One embodiment of the present invention is directed to compositions and methods for enhancing attachment of soft tissues to a metal prosthetic device. In one embodiment a construct is provided comprising a metal implant having a porous metal region, wherein the porous region exhibits a nano-textured surface, and a biocompatible polymer matrix coating the nano-textured surface. The polymer matrix coating comprises a naturally occurring extracellular matrix with biocompatible inorganic materials distributed within the matrix, or a biocompatible polymer and an osteo-inductive agent.

System and method for attaching soft tissue to an implant comprising a nanotextured surface

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.

A nested trigger assembly for a surgical instrument may generally comprise a first trigger and a second trigger, wherein the first trigger and the second trigger are movable together on a first stroke of the nested trigger assembly, wherein the second trigger is configured to be biased away from the first trigger after the first stroke and before a second stroke, and wherein the second trigger is configured to be moved toward to the first trigger during the second stroke. A surgical instrument may generally comprise a shaft comprising a proximal end and a distal end, a handle extending from the proximal end, wherein the handle comprises a gripping portion, and a nested trigger assembly extending from the handle.
