  • Publication number: 20210338221
    Abstract: Devices and methods are disclosed herein for accessing the hip joint. A first device can be securely attached to the capsule of a joint. The first device can tent the capsule to increase the volume of the peripheral compartment. A second device can be biased against the first device to pierce the tented capsule and create a portal. Devices and methods are also disclosed herein for distending the capsule of a joint. A distention device may access a portal established within the capsule. The distention device can expand the capsule by applying an expansive force within the peripheral compartment. The distention device can maintain distention of the peripheral compartment while other devices access the joint.

  • Patent number: 11096682
    Abstract: A suture manipulating instrument for passing and retrieving suture through a tissue includes a handle mechanism, an elongate shaft extending from the handle, and a working distal end. The working distal end includes a needle body, a lumen defined by the needle body, a tissue penetrating distal tip, and a lateral slot. A preformed inner member is movably disposed within the lumen of the needle. The handle mechanism is used to extend the wire from the lateral slot of the needle, and to retract the wire into the lateral slot, allowing the working end of the instrument to grasp and manipulate suture by pinning and/or trapping the suture against the needle. In embodiments the inner member is further retracted within the needle lumen, drawing a length of suture into the needle lumen. The suture is subsequently ejected from the needle lumen to form a suture loop.

  • Patent number: 10973511
    Abstract: A suturing apparatus comprises a pair of jaws. A bendable needle housed in one of the jaws is adapted to carry a suture. A suture receiver is disposed adjacent to, or integral with, the opposite jaw to help disengage the suture carried by the bendable needle. A transition block curves the needle and directs it in a direction generally unparallel to an axis of the carrying jaw. The jaw housing the needle may include a lateral opening through which the suture may be inserted. The needle may also include a lateral notch which may be aligned with lateral opening to receive the suture. An actuator coupled to the needle enables the user to move the needle proximally to align the notch with the lateral slot.

  • Publication number: 20210052268
    Abstract: A surgical instrument can manipulate and pass suture through tissue. The device can easily pass suture through tissue with the suture fixed to the mechanism or where the suture is captured by the mechanism and allowed to slide. Along with this ability to control suture in one of two ways is a feature to provide a large amount of suture on the other side of the tissue that will be relatively easy for the surgeon to grab and pull out of the arthroscopic portal. The device includes a handle with a hollow shaft extending therefrom and a set of fingers movable into and out of the shaft. The fingers can be designed to capture suture, permit the suture to slide while captured, and optionally hold the suture in the device.

  • Publication number: 20200345343
    Abstract: A suture passing device includes a jaw assembly that is moved to an open configuration after exiting a hollow needle distal tip and moved to a closed configuration when retracted into the needle tip. The jaw assembly may include a pair of jaw members biased to a default diverging configuration. A suture capturing mechanism formed on the jaw members securely captures suture to both push and pull the captured when the jaw assembly is retracted into the hollow distal tip. The jaw members have configurations of teeth that may be staggered axially and vertically.

  • Patent number: 10555731
    Abstract: A surgical suturing device having an axis extending between a proximal end and a distal end is operable to move a suture through body tissue. An actuating rod extends between the handle assembly and the shaft. A needle assembly at the distal end of the actuating rod is movable with the actuating rod between an extended state and a retracted state. Bifurcated portions of the needle assembly define a suture slot, the bifurcated portions have a proximate relationship when the needle assembly is in the retracted state and having a separated relationship when the needle assembly is in the extended state. The needle assembly is biased to the retracted state and the bifurcated portions are biased to the separated relationship. A handle assembly is configured to releasably receive the needle assembly and is operable to move the needle assembly between a free suture state and a captured suture state.
