Electrophysiology mapping and visualization systems are described herein where such devices may be used to visualize tissue regions as well as map the electrophysiological activity of the tissue. Such a system may include a deployment catheter and an attached hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. A position of the catheter and/or hood may be tracked and the hood may also be used to detect the electrophysiological activity of the visualized tissue for mapping.

A surgical system is disclosed including an end effector, a control circuit, a closure member, and a firing member. The end effector includes a first jaw, a second jaw, and an electrode. The first jaw is rotatable relative to the second jaw between an open position and a close position to capture tissue therebetween. The electrode is configured to conduct a sub-therapeutic RF current to the tissue. The control circuit is operably coupled to the electrode. The control circuit is configured to measure impedance of the tissue over time based on the sub-therapeutic RF current. The closure member is configured to move the first jaw towards the second jaw at a closure rate based on the impedance of the tissue. The firing member is configured to move within the end effectors towards a fired position at a firing rate based on the impedance of the tissue.

The present technology relates to intracardiac pressure monitoring devices, and associated systems and methods. In some embodiments, the present technology includes a device for monitoring pressure within a patient's heart. The device can include a pressure sensor configured to reside within a first chamber of a heart of a patient, and a pressure transmission element configured to extend from the first chamber through a septal wall to a second chamber of the heart of the patient. When the device is implanted in the patient's heart, the pressure transmission element is configured to transmit pressure from the second chamber to the pressure sensor residing within the first chamber.

A leadless cardiac pacemaker device is configured to provide HIS bundle pacing and contains a housing having a tip, a first electrode arranged on the housing in the vicinity of the tip, the first electrode being configured to engage with intra-cardiac tissue, and a second electrode arranged on the housing at a distance from the tip of the housing. A processor is enclosed in the housing and operatively connected to the first electrode and the second electrode. The processor is configured to process a reception signal received by at least one of the first electrode and the second electrode and to generate a pacing signal to be emitted using at least one of the first electrode and the second electrode.

The present technology relates to power management for interatrial shunting systems. In some embodiments, the present technology includes a system for shunting blood between a left atrium and a right atrium of a patient. The system can include a shunting element and a plurality of active electronic components operably coupled to the shunting element. At least some of the active electronic components have different power consumption characteristics. The system also includes a plurality of energy storage components, with some of the energy storage components have different characteristics. During operation, the system is configured to receive a signal indicating that an active electronic component is to be operated, and select an energy storage component associated with power output characteristics capable of accommodating the power consumption characteristics of the active electronic component. The system is further configured to instruct the selected energy storage component to power operation of the active electronic component.

A catheter has single axis sensors mounted directly along a portion of the catheter whose position/location is of interest. The magnetic based, single axis sensors are on a linear or nonlinear single axis sensor (SAS) assembly. The catheter includes a catheter body and a distal 2D or 3D configuration provided by a support member on which at least one, if not at least three single axis sensors, are mounted serially along a length of the support member. The magnetic-based sensor assembly may include at least one coil member wrapped on the support member, wherein the coil member is connected via a joint region to a respective cable member adapted to transmit a signal providing location information from the coil member to a mapping and localization system. The joint region provides strain relief adaptations to the at least one coil member and the respective cable member from detaching.

Various surgical systems are disclosed. A surgical system comprises a robotic tool, a robot control system, a surgical instrument, and a surgical hub. The robot control system comprises a control console and a control unit in signal communication with the control console and the robotic tool. The surgical hub comprises a display. The surgical hub is in signal communication with the robot control system. The surgical hub is configured to detect the surgical instrument and represent the surgical instrument on the display.

A surgical instrument is disclosed. The surgical instrument comprises an end effector comprising an ultrasonic blade and a clamp arm. The clamp arm is movable relative to the ultrasonic blade to transition the end effector between an open configuration and a closed configuration to clamp tissue between the ultrasonic blade and the clamp arm. The surgical instrument further comprises an ultrasonic transducer configured to generate an ultrasonic energy output and a waveguide configured to transmit the ultrasonic energy output to the ultrasonic blade. The surgical instrument further comprises a control circuit, configured to detect an immersion of the end effector in a liquid and compensate for heat flux lost due to the immersion of the end effector in the liquid.

Systems and methods for noncontact ablation of tissues or materials in/on the body using an ablation catheter that has a directional ablation unit. The ablation unit has a set of individual transducer (e.g., ultrasound) elements that are movably positioned. A position adjustment element (a deformer) is movable with respect to the ultrasonic transducer to alter the positions of the individual transducer elements and thereby alter the directions in which the transducer elements emit ultrasonic energy. In one embodiment, the ablation catheter is a lumen catheter through which a positioning/measurement catheter can be inserted. The luminal ablation catheter is inserted through the skin and into the body via conventional methods. The ablation and positioning catheters can be used to make electrical measurements with respect to the surrounding tissue, and the ablation catheter can be used to emit energy in a desired direction and/or pattern to ablate target tissue.
