Low profile spinal tethering devices
Methods and devices for treating spinal deformities are provided. In one exemplary embodiment, a low-profile spinal anchoring device is provided for receiving a spinal fixation element, such as a tether, therethrough. The device generally includes a staple body that is adapted to seat a spinal fixation element, a fastening element for fixing the staple body to bone, and a locking assembly for coupling a spinal fixation element to the staple body. In one embodiment, the locking assembly includes a washer that is adapted to couple to the staple body such that the spinal fixation is disposed therebetween, and a locking nut that is adapted to engage the staple body to mate the washer to the staple body.
DEPLOYMENT TECHNIQUES FOR ANNULOPLASTY IMPLANTS
A method is described for use at a valve of a heart of a subject, the valve having an annulus, and the heart having an atrium upstream of the valve. A distal end of a manipulator is transluminally advanced into the atrium. A first part of an implant that includes an elongated contracting member is anchored to a first site on the annulus using the manipulator. The distal end of the manipulator is then pointed at a second site on the annulus such that a central longitudinal axis of the manipulator is disposed at an angle of 45-90 degrees with respect to a surface of the annulus. A second part of the implant is then anchored to the second site using the manipulator. Subsequently, the first site and the second site are drawn together by applying tension to the contracting member. Other embodiments are also described.
FIXATION DEVICE DELIVERY SYSTEM
A fixation device delivery system is described. The system includes a driver and a cooperating fixation element featuring a barb which becomes active upon deployment in the inner abdominal wall.
DEVICE AND SYSTEM FOR HERNIA REPAIR
A suture device comprises a needle (5) which is movable between a retracted configuration and an extended configuration and a drive for rotating the needle between the retracted and extended configurations. The drive comprises an axle (18) which is rotated by a rack (12) and pinion (10) system.
Implant and anchor assembly
An implant assembly comprising an implant having a load bearing surface with a contour corresponding to a patient's articular surface, and a bone facing surface including a fixation element, an anchor configured to be secured to bone beneath said patient's articular surface, said anchor including a second fixation element, and wherein said first fixation element is configured to be secured to said second fixation element.
Connecting end effectors to surgical devices
A surgical fastener applying device for releasable connection to an end effector is provided. The surgical fastener applying device includes an elongated body portion having an outer tube and an inner shaft assembly. The inner shaft assembly defines a non-circular bore in a distal end thereof. The inner shaft assembly is longitudinally movable through the outer tube. The outer tube and the inner shaft assembly define corresponding openings extending radially therethrough. The surgical fastener applying device includes a detent movable within the openings of the elongated body portion. The detent floats between the end effector and the elongated body portion to enable selective connection between the end effector and the elongated body portion.
Fastener cartridge
A fastener cartridge can be used with a shaft of a tool during an orthopedic procedure. The fastener cartridge can have a main housing that can be attached to fastener housing including a fastener chamber and a backstop component. The fastener chamber includes a plurality of non-flexible tabs and the backstop component includes a plurality of resiliently flexible tabs. The fastener housing is configured to include a plurality of fasteners that are arranged therein such that the longitudinal axes of the fastener chamber and the plurality of fasteners are collinear. The plurality non-flexible tabs prevent one of the fasteners from inadvertently passing entirely out of an outlet of the fastener chamber and the plurality of resiliently flexible tabs allow the fasteners to move axially in the first direction and restrict movement of the fasteners in a second direction opposite the first direction.
ROBOTIC SURGERY
A method of using a robotic guidance system for performing surgery on a spine is provided. The method includes utilizing a computerized tomographic scan image of a location on a spinal column of a patient, such that the computerized tomographic scan image is connected to a computer and visible on a monitor connected to the computer. The method also includes attaching a coupling component to the spinal column of the patient, coupling a marker to the coupling component, and imaging, with a fluoroscope, the view of the spinal column of the patient, wherein the fluoroscope image is transmitted to the computer and visible on the monitor and the at marker is clearly visible in the fluoroscope image. The method also includes positioning a cannula, with a robotic mechanism, to a first position relative to a vertebra in the spinal column of the patient, drilling a passage through the cannula into bone of the vertebra in the spinal column of the patient, inserting a guidewire through the cannula into the passage in the bone of the vertebra in the spinal column of the patient, and positioning a screw into the bone of the vertebra in the spinal column of the patient.
IMPLANT INSERTERS
Inserters for dynamic implants include hooks that engage connecting means of the implants and rams that press against bridges of the implants when the inserters are actuated.
Surgical device for use with robotic surgical systems
Surgical devices for use with robotic surgical systems and their methods of use are described. In some embodiments, the surgical device may include an actuator that interfaces with an end effector of an arm of a robotic surgical system. An output from the end effector may actuate the actuator to perform an operation of the surgical device. In some embodiments, the surgical device may include a retainer that retains at least a portion of the surgical device on a distal portion of the arm of the robotic surgical system during actuation. In other embodiments, the surgical device may include a portion that is engaged by a second robotic surgical arm to hold at least a portion of the surgical device stationary relative to the robotic surgical arm engaged with the actuator of the surgical device.
