  • Publication number: 20200107843
    Abstract: A system and method is provided for generating ultrasound at the tip of an intravascular catheter. This may be used for the treatment of vascular occlusions, including chronic total occlusions (CTOs) and thrombotic occlusions (e.g., deep vein thrombosis, stroke, myocardial infarction). For instance, the systems and methods may be used to induce cavitation to enhance the enzymatic degradation of a vascular occlusion. In some configurations, the approach employs a hollow cylindrical transducer, electrically stimulated in the radial direction at a frequency corresponding to the length mode excitation, thereby projecting ultrasound forwards past the catheter tip. This design overcomes electrical impedance issues for the generation of low frequencies with a smaller diameter transducer capable of negotiating a coronary artery. The hole within the transducer may accommodate a guidewire to facilitate its placement adjacent to the proximal portion of the occlusion.

    Abstract: A device and method for establishing retrograde blood flow during recanalization of a vessel having a targeted blockage. While in a collapsed state an occluding component is introduced distally intravascularly traversing the targeted blockage to its distal side. Then, the occluding component transitions to an expanded state having an enlarged diameter forming a seal with an internal wall of the vessel prohibiting anterograde blood flow beyond the expanded occluding component. Retrograde blood flow is thereby established in a region of the vessel bound at one end by the occluding component and at an opposite end by the targeted blockage by dispensing a flushing fluid into the region of the vessel.

  • Publication number: 20200107855
    Abstract: Devices, methods and systems are described that enable achieving a working diameter during high-speed rotation that is greater than a resting diameter. The various embodiments comprise structural modifications to rotational drive shafts that result in a radial shift of the center of mass of an affected portion of the drive shaft away from the rotational axis of the drive shaft. As a result, high-speed rotation of the drive shaft induces orbital motion. Certain aspects include more dense plugs inserted into or integrated into one or more spaced apart locations in one or more wire turns or filars along the drive shaft. One or more filars may comprise a denser portion than other filars. A flexible strip of preferably semi-circular cross-sectional shape may be affixed to the interior of the drive shaft within the lumen to add mass and affect the location of the center of mass.

  • Publication number: 20200107856
    Abstract: Devices, methods and systems are described that enable achieving a working diameter that is greater than a resting diameter and to stimulate fluid circulation during high-speed rotation. The drag coefficient of the drive shaft is increased and, in some embodiments, the mass is increased. Among other advantages, the resulting drive shaft with an eccentric element integrated with and/or attached thereto will achieve orbital motion at a rotational speed that is less the rotational speed required to achieve orbital motion without the increased drag coefficient. The concomitant increase in fluid flow and/or fluid stirring at a comparatively lower rotational speed is a further advantage. These characteristics may allow, therefore, a smaller diameter abrasive element to be used which is advantageous in small and/or highly tortuous vessels.

  • Publication number: 20200107873
    Abstract: A forceps instrument comprises, for the support of at least one pivotally supported branch, a bearing insert which is inserted into a base in order to support at least one pivotable branch. The bearing insert may be inserted transversely with respect to the pivot axis into a corresponding compartment of the base and fixed there in the compartment, for example due to detent action. The bearing insert comprises two bearing elements, such as cylindrical journals, which are arranged on bearing parts of the bearing insert, without being in contact with each other, said bearing parts having the form of plates, for example, that are oriented parallel to each other. The two journals come into engagement with corresponding openings of the branch, in which case the distance remaining between the end sides of the journals can be used for the arrangement of miscellaneous elements, such as a cutting knife.

  • Publication number: 20200107874
    Abstract: A surgical instrument (100) includes first and second shaft members (110, 120) defining proximal and distal end portions (112a, 122a, 112b, 122b) and including handles (114, 124) at the proximal end portions (112a, 122a) thereof. A pivot member (130) couples the distal end portions (112b, 122b) with a gap (G) defined therebetween proximally of the pivot member (130). First and second jaw members (210, 220) extend distally from the shaft members (110,120), distally of the pivot member (130). A lockout bar (160, 560, 660, 760) is movable between an unlocked position, withdrawn from the gap (G), and a locked position, disposed within the gap (G). The handles (114, 124) are pivotable between spaced-apart and approximated positions to pivot the jaw members (210, 220) between open and closed positions. The handles (114, 124) are yawable between the approximated position and a yawed position to yaw the jaw members (210, 220) between the closed position and a cutting position.

    Abstract: A spine measurement system comprises an optical measurement probe, one or more targets, a fluoroscope, and a remote station. A-P and lateral images of the spine are taken using the fluoroscope and provided to the remote station. The remote station includes computer vision that can identify endplates and pedicle screws in the spine. The computer vision in the remote station is further used to identify vertebra and bone landmarks of the spine. The remote station can generate quantitative measurement data such as Cobb angles and axial rotation of the spine from the fluoroscope images that correspond to the spine deformity. The optical measurement probe can send images of the spine with pedicle screw extenders extending from the pedicle screws to the remote station. The remotes station using computer vision can provide spine metrics in real-time by tracking position of the pedicle screw extenders.
