  • Patent number: 11446052
    Abstract: Surgical instruments and system and methods for using surgical instruments are disclosed. A surgical instrument comprises an end effector comprising an ultrasonic blade and clamp arm, an electrode, an ultrasonic transducer, and a sensor coupled to a control circuit. The electrode receives electrosurgical energy from a generator and applies the electrosurgical energy to the end effector to weld tissue based on the generator generating a drive signal. The ultrasonic transducer ultrasonically oscillates the ultrasonic blade in response to the drive signal. The control circuit receives a signal from the sensor indicative of a surgical parameter, determines a weld time of a surgical operation based on the sensor signal, and varies one or more of a clamp arm pressure applied by the clamp arm and a power level of the electrosurgical energy to maintain one or more of a predefined heat flux or power applied to tissue loaded in the end effector.

  • Patent number: 11445911
    Abstract: The invention may be applied to selectively heat a diseased area in the lung while minimizing heating to the healthy area and surrounding tissue. This can be done by exposing the lung to an electromagnetic field causing dielectric or eddy current heating. The invention is particularly useful for treating emphysema as the diseased areas in emphysema patients have reduced blood flow. The diseased area will heat up rapidly while the healthy tissue will be cooled by the blood flow. This is particularly effective for treating emphysema because of the low mass of the lungs and the high blood flow. To avoid heating of surrounding organs the direction of the electromagnetic energy may be switched in a way it always passes through lungs but only intermittently passes through adjacent organs.

  • Patent number: 11432868
    Abstract: A surgical instrument system includes an end effector, a generator, and a controller. The end effector includes an ultrasonic blade and at least one electrode surface. The generator provides power to the end effector. The end effector applies ultrasonic energy to tissue via the blade or RF energy to tissue via the at least one electrode surface. The controller is configured to select between one or both of ultrasonic energy or RF energy, and thereby control the generator to provide the selected one or both of ultrasonic energy or RF energy at the end effector, based on a sensed operating condition of the end effector. The controller may select between ultrasonic energy and RF energy based on whether a clamp arm is in an open position relative to the blade, based on which button is being activated, and based on whether tissue is sensed at the end effector.

  • Patent number: 11432874
    Abstract: A device positionable in a cavity of a bodily organ (e.g., a heart) may discriminate between fluid (e.g., blood) and non-fluid tissue (e.g., wall of heart) to provide information or a mapping indicative of a position and/or orientation of the device in the cavity. Discrimination may be based on flow, or some other characteristic, for example electrical permittivity or force. The device may selectively ablate portions of the non-fluid tissue based on the information or mapping. The device may detect characteristics (e.g., electrical potentials) indicative of whether ablation was successful. The device may include a plurality of transducers, intravascularly guided in an unexpanded configuration and positioned proximate the non-fluid tissue in an expanded configuration. Expansion mechanism may include helical member(s) or inflatable member(s).

  • Patent number: 11426308
    Abstract: A surgical device and procedure are provided for smoothly and easily accessing tissue to perform microsurgery, including a capsulotomy of a lens capsule of an eye. The device includes a handpiece with a tip for insertion into an incision in the cornea of the eye. A sliding element is disposed within the handpiece and a suction cup is mounted to the sliding element. The sliding element can be translated to move the suction cup into and out of the handpiece. A compression mechanism associated with the suction cup and the handpiece compresses the suction cup for deployment through the tip of the handpiece. The suction cup can expand inside the anterior chamber into a cutting position on the lens capsule. A cutting element mounted to the suction cup is used to cut a portion of the lens capsule and to remove the portion from the eye. The cutting element may be mounted to a cutting element support structure in a way that prevents heating of the device.

  • Patent number: 11426236
    Abstract: This invention provides a system and method that allows a therapeutic device, such as an atrial fibrillation microwave ablation catheter or ablation tip to be guided to a remote location within a body cavity and then accurately immobilized on the tissue, including that of a moving organ, such as the heart. In various embodiments, the system and method also enables accurate movement and steering along the tissue, while in engagement therewith. Such movement and engagement entails the use of vacuum or microneedle structures on at least two interconnected and articulated immobilizers that selectively engage to and release from the tissue to allow a crawling or traversing walking across the organ as the therapeutic catheter/tool tip applies treatment (AGE devices). In further embodiments that lack a movement capability (AID devices), the immobilizers allow a predetermined position for the introduced device to be maintained against the tissue while a treatment is applied to the location adjacent thereto.
