  • Patent number: 11013907
    Abstract: Various surgical devices and methods are provided for monitoring and regulating tissue compression and cutting to improve tissue effect. In general, these devices include a handle portion, an elongate shaft, and an effector disposed at a distal end of the shaft and configured to engage tissue. In one embodiment, one or more sensors can be positioned at various locations on the device and can determine a force applied to tissue engaged by the end effector. When the force exceeds a threshold, a notification signal can be issued to a user. In another embodiment, a sensor can determine an amount of current moving between jaws of the end effector and a controller can slow a speed of the cutting element when the sensed current exceeds a threshold amount.

    Abstract: Measurement of a leading edge of an instrument passing from a first medium having a first density to a second medium having a second density using a displacement sensor alone. In particular, a displacement signal, a velocity signal, and an acceleration signal measured from or derived from a displacement sensor are analyzed to determine when the leading edge of the instrument passes from the first material to the second material as the leading edge of the instrument is advanced relative to the material. For instance, the measurement may be used to output an occurrence signal that indicates to a user that the instrument has passed from the first medium to the second medium. Additionally, a length measurement of the path of the instrument when passing from the first medium to the second medium may be recorded, and/or the instrument may be controlled (e.g., the instrument may be stopped).

  • Patent number: 10595823
    Abstract: There are disclosed embodiments of devices and methods for imaging the inside of a body part, particularly a blood vessel. In particular embodiments, a catheter has a tip chamber, within which is an ultrasound transducer mounted on a pivot mechanism, a motor for turning the transducer, and an implement for pivoting the transducer. Examples of such an implement are a linear motor, a shaft or filament, and the pivot mechanism may be biased to return to a base position when the implement is not pivoting the transducer. In other embodiments, a mirror reflecting ultrasound signals from the transducer may be rotated and/or pivoted, using similar mechanisms.

  • Patent number: 10582950
    Abstract: A method is provided for puncturing a fossa ovalis of a heart, the method including inserting a catheter into a right atrium of the heart, and advancing a distal portion of the catheter toward an interatrial septum of the heart. A flexible longitudinal member is slid through openings disposed at the distal portion of the catheter, such that the flexible longitudinal member is made to loop around a portion of an inside perimeter of the fossa ovalis. While the flexible longitudinal member is looped around the portion of the inside perimeter of the fossa ovalis, a hole is punctured in the fossa ovalis at a puncturing point.

  • Patent number: 10582942
    Abstract: Methods and devices for blunt dissection include a drive mechanism comprising an elongate rotary drive train having a first proximal end connected to a mounting base for attaching to a handle or a surgical robot and a second distal end. The drive mechanism comprises a differential dissecting member (DDM) configured to be rotatably attached to the second distal end. The drive mechanism further comprises a mechanism configured to mechanically rotate the DDM about a substantially transverse axis of member rotational oscillation, thereby causing at least one tissue engaging surface to move in at least one direction against complex tissue and selectively engage the complex tissue such that when the DDM is pressed into the complex tissue, the at least one tissue engaging surface moves across the complex tissue and disrupts at least one soft tissue in the complex tissue, but does not disrupt firm tissue in the complex tissue.

  • Patent number: 10582965
    Abstract: An endoscopic forceps includes a housing having a shaft extending therefrom for treating tissue. A longitudinal axis is defined through the shaft. An end effector assembly is operably coupled to a distal end of the shaft and includes a pair of first and second jaw members. A rotating assembly operably coupled to the shaft is configured to rotate the shaft and the end effector about the longitudinal axis. A drive assembly is configured to selectively and releasably engage the rotating assembly. Engagement of the rotating assembly with the drive assembly couples the rotating assembly to the shaft such that the shaft is rotatable about the longitudinal axis in a predetermined direction when the rotating assembly is rotated. And, disengagement of the rotating assembly from the drive assembly uncouples the rotating assembly from the shaft such that the shaft is non-rotatable about the longitudinal axis when the rotating assembly is rotated.

  • Patent number: 10561433
    Abstract: An instrument that includes an outer member, an inner member, and a jaw assembly. The inner member includes a first arm and a second arm. The jaw assembly includes a first jaw and a second jaw. The first jaw is connected to the first arm at a first pivot joint and to the outer member at a second pivot joint. The second jaw is connected to the second arm at a third pivot joint and to the outer member at a fourth pivot joint. The inner member is adapted to be moved distally relative to the outer member so that the first jaw pivots about the second pivot joint towards the second jaw and the second jaw pivots about the fourth pivot joint towards the first jaw thus moving the jaw assembly from the open position towards the closed position.

  • Patent number: 10524826
    Abstract: Rotational atherectomy devices and systems can remove or reduce stenotic lesions in implanted grafts by rotating one or more abrasive elements within the graft. The abrasive elements can be attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly that includes a driver for rotating the drive shaft. In particular implementations, individual abrasive elements are attached to the drive shaft at differing radial angles in comparison to each other (e.g., configured in a helical array). The centers of mass of the abrasive elements can define a path that fully or partially spirals around the drive shaft.

  • Patent number: 10525231
    Abstract: A flexible, elongated catheter tube having distal and proximal ends and a laser cut section there between. The laser cut section makes up a majority of the catheter length and is cut in a continuous helical pattern forming interlocking teeth which can be sinusoidal, triangular, square or likes shapes, preferably sinusoidal. The interior of the catheter tube has a polymeric bi-layer of a nylon or like polymer at the interface of the tube interior and a Teflon or like polymer forms the interior lumen of the catheter. The exterior of the tube has a thin polymer coating of nylon or the like. A short portion of the distal end is uncut and is followed by a narrower terminal section which can be tapered for better blockage penetration. The interlocking teeth disengage and reengage in a fish scale manner without undergoing plastic deformation and without substantial polymer separation.
