A surgical stapling instrument comprising an end effector, an RFID tag, and a control circuit is disclosed. The end effector comprises an anvil, a staple cartridge, and a contact assembly configured to contact tissue. The staple cartridge comprises staples removably stored therein. The anvil and the staple cartridge are configurable between an open configuration and a closed configuration. The RFID tag is configured to store information about the staple cartridge. The control circuit is operably coupled to the contact assembly. The control circuit is configured to interrogate the RFID tag to determine the information about the staple cartridge, transmit an electrical signal to tissue contacting the contact assembly, determine a characteristic of the tissue contacting the contact assembly based on the electrical signal, and change an operational parameter of the surgical stapling instrument based on the characteristic of the tissue.

A robotic surgical system includes a surgical instrument and a robotic surgical assembly. The robotic surgical assembly defines an instrument opening and includes a floating plate and a drive assembly. The floating plate is movable between an extended position and a compressed position. The surgical instrument is laterally receivable in the instrument opening of the robotic surgical assembly while the floating plate is disposed in the compressed position. The floating plate is movable to the extended position to couple the surgical instrument to the robotic surgical assembly while the surgical instrument is received in the instrument opening of the robotic surgical assembly.

A medical device and associated methods are disclosed. In one example, the medical device includes an electrosurgical forceps. In selected examples, one or more structural components of the electrosurgical forceps includes a sintered ceramic microstructure. In selected examples other medical devices, including a debrider and a lithotripter, include a sintered ceramic microstructure.

An apparatus includes a shaft assembly, an end effector, a control module, a first electrical connector, and a plurality of nonconductive structures. The first electrical connector is operatively coupled with the control module and includes a first plurality of electrical contacts. At least one electrical contact of the first plurality of electrical contacts is configured to transfer a power output from the control module to a second plurality of electrical contacts of a second electrical connector while the first and second electrical connectors are coupled. The nonconductive structures are disposed adjacent each of the plurality of first electrical contacts. The nonconductive structures are configured to prevent a signal interference between each electrical contact of the first plurality of electrical contacts.

Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to the thrombectomy system. The system can an interventional element configured to be delivered to a treatment site and to be electrically coupled to an extracorporeal power supply. The interventional element can be surface treated (e.g., via electrochemical anodization) to achieve a desired electrical conductivity gradient over the surface of the interventional element. The electrical conductivity gradient can result in a more desirable surface charge distribution upon delivery of electrical current to the interventional element.

An eyelid manipulation device includes a rigid contact portion dimensioned to be insinuated between an eyelid and a globe, the contact portion having an upwardly-facing surface opposite a downwardly-facing surface, each of the surfaces extending between a distal side and a proximal side of the contact portion; and a rigid stem integral with and extending upwardly from the proximal side of the contact portion. In embodiments, the stem is connectable to a handle. In other embodiments, the stem is elongated, thereby serving as a handle. The eyelid manipulation device may be used during treatment of Meibomian glands or otherwise during treatment of dry eye symptoms.

A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied so as to apply various clamping forces and pressures to soft tissue captured within the staples. In at least one embodiment, the staples can include crowns formed thereon which can be utilized to adjust or control the clamping force and/or pressure applied by the staples.

A sleeve insertion assembly includes a sleeve inserter defining an inner chamber and having a distal end and a proximal end opposite the distal end, a sleeve receivable within the inner chamber, and a blade guard receivable within the sleeve and having a cylindrical body that defines an interior and an open end. The open end is sized to receive jaw members of an end effector into the interior but prevent the end effector from entering the interior, and the blade guard is forced out of the sleeve when the sleeve is installed on the end effector.

Left atrial appendage (LAA) occlusion device including a membrane, a plurality of fixation splines and a deployment hub, the plurality of fixation splines for affixing the LAA occlusion device to an ostium of the LAA, the deployment hub being positioned in the membrane, the deployment hub including a threaded aperture and a one-way valve, for enabling a toxin to be entered into the LAA through the deployment hub.

Methods and surgical tools for treating back pain use a spinal facet debridement tool with cautery and denuding action and minimally invasive protocol that can denude and cauterize soft tissue associated with a synovial capsule of the spinal facet joint.
