  • Patent number: 10966737
    Abstract: Described herein is a shock wave device for the treatment of vascular occlusions. The shock wave device includes an outer covering and an inner member inner connected at a distal end of the device. First and second conductive wires extend along the length of the device within the volume between the outer covering and the inner member. A conductive emitter band circumscribes the ends of the first and second wires to form a first spark gap between the end of the first wire and the emitter band and a second spark gap between the end of the second wire and the emitter band. When the volume is filled with conductive fluid and a high voltage pulse is applied across the first and second wires, first and second shock waves can be initiated from the first and second spark gaps.

  • Patent number: 10952789
    Abstract: A connection mechanism and manufacturing method for a surgical instrument includes an inner shaft member that extends at least partially through an elongated shaft member of the instrument and defines proximal and distal ends and is selectively movable in a longitudinal direction with respect to the elongated shaft member and includes at least one aperture that extends partially along the longitudinal direction and disposed distally from the proximal end. The inner shaft member enables a drive collar member to slide on the inner shaft member and reciprocate along the longitudinal direction. A drive collar stop member slides on the inner shaft member and moves along the longitudinal direction. The drive collar stop member then moves in a direction relative to the longitudinal axis to engage the aperture and limit further longitudinal motion of the drive collar member. An inner shaft stop member limits movement of the inner shaft.

  • Patent number: 10898179
    Abstract: Systems and methods for soft tissue to bone repairs, without knot tying. The soft tissue repair systems include self-cinching constructs with splices, loops and inserts that are pre-loaded onto knotless anchors to position the self-locking, adjustable construct at the repair site. The splice incorporates an insert in the form of a flexible strand with at least one barb, or simply in the form of a cut length of suture or braid that is inserted into the center of the cinching loop to create a thicker portion. When the cinching loop is tightened, the insert prevents loosening of the loop, locking in the cinching loop and preventing movement of the loop.

  • Patent number: 10864049
    Abstract: A docking system for a mechanical telemanipulator is provided, optionally to be used with a mechanical telemanipulator with a master-slave configuration. The docking system is configured to allow for safe and secure immobilization of a handle or master manipulator of a mechanical telemanipulator with a master-slave configuration so as to prevent movement of a slave manipulator or instrument. While the docking element can be deployed on any mechanical telemanipulator, it can advantageously be used on a surgical platform comprising a mechanical telemanipulator with a master-slave configuration. In this context, the docking system can be used to secure the handle portion or master manipulator of the surgical platform to safely prevent undesirable movement of a slave manipulator or surgical instrument.

  • Patent number: 10792064
    Abstract: A surgical instrument includes a housing, an end effector, a movable handle, and a drive assembly. The movable handle includes first and second cantilever spring arms and is movable relative to the housing between a spaced-apart position and an approximated position. The first cantilever spring arm is flexed upon movement of the movable handle from the spaced-apart position towards the approximated position to bias the movable handle towards the spaced-apart position. The drive assembly is operably coupled between the movable handle and the end effector such that movement of the movable handle from the spaced-apart position towards the approximated position moves the end effector from an open position towards a clamping position for clamping tissue. The second cantilever spring arm is flexed upon application of a threshold pressure to tissue clamped by the end effector to control an amount of pressure applied to tissue clamped by the end effector.

  • Patent number: 10758224
    Abstract: A system for controlling a relationship between first and second bodies and made up of a suture assembly with at least a first suture configured to define a restrictable loop structure with the suture assembly in an operative state. At least first and second restrictable sub-loops cooperatively define a first loop that can be reduced in size to thereby produce a force on the first and second bodies that urges them towards each other. A first loop length has a first sliding portion with a second loop length having a second sliding portion. At least one knot extends around the first and second sliding portions. The first and second sliding portions, upon each being moved within the at least one knot in a tightening sliding direction, cause a size of a respective sub-loop to be reduced.
