A spinal fixation system comprising at least one fastener having a fastener head at a proximal end and at least one body. The body comprises a rod receiving channel for receiving a fixation rod, a pressure cap for engaging the fastener head, and a fastener head receiving chamber for retaining the fastener head within the body. The fastener head receiving chamber allows for multi-axial movement of the body in relation to the fastener when the pressure cap is disengaged from the fastener head. The body is secured in a mono-axial position in relation to the fastener when the pressure cap is biased against the fastener head.

Lockable pedicle fastener

The present disclosure relates, according to some embodiments, to orthopedic implantable device technology, and more specifically to variable angle implantable devices, systems, and methods.

Variable angle screws, plates and systems

The present disclosure generally relates to a retractor device for retracting soft tissue to provide access to a surgical site. The retractor device includes a plurality of arms coupled to a frame and operatively coupled to a ring disposed at least partially within the frame. Related methods of using the retractor device are also described.

Retractor device and method

The present disclosure relates, in some embodiments, to locking mechanisms for a fastener (e.g., a bone screw) and associated devices, systems, and methods. According to some embodiments, a lockable bone plate assembly may comprise, for example, a bone plate and a bone screw assembly. A bone plate may comprise, in some embodiments, at least one through hole, the at least one through hole having at least one bone plate hole circumferential recess. According to some embodiments, a bone screw assembly may comprise (a) a bone screw, (b) at least one deployable protrusion, and/or (c) a protrusion driver. The present disclosure further relates, in some embodiments, to methods for bone (e.g., vertebral) fixation. For example, a method may comprise contacting at least a portion of a spine (e.g., cervical spine) of a subject with a lockable bone plate assembly.

Plate/screw locking mechanism devices, systems and methods

An implantable orthopedic assembly comprises a bone fixator and head assembly for securing a stabilizing rod to the spine. The head assembly allows multi-axial repositioning of the bone fixator relative to the head assembly. A primary drive interface located on the bone fixator may be used to adjust the depth of bone penetration when the bone fixator and head assembly are substantially coaxial. A secondary drive interface located on the head assembly may be used to adjust the depth of bone penetration while independently adjusting the stabilizing rod position when the bone fixator and the head assembly are not coaxial, transferring torsional loads to the bone fixator.

Multi-axial pedicle fixation assembly and method for use

The present disclosure relates, according to some embodiments, to translational pedicle screw systems. A translational pedicle screw system may comprise a bone screw secured within a saddle. Different mechanisms may provide for translational movement of the saddle relative to the bone screw. In some embodiments, a saddle may comprise an elongated distal channel configured to provide a translational motion of a bone screw head disposed therein. In some embodiments, a saddle may comprise a discoidal recess configured to receive a corresponding discoidal section of a bone screw. The discoidal recess and the discoidal section may allow for a rotational offset of the saddle relative to the bone screw. In some embodiments, a proximal portion of a bone screw may comprise an attachment section configured to engage with a removable bone screw head. The removable bone screw head may translate laterally along the attachment section of the bone screw.

Translational pedicle screw systems

An injectable substance delivery device comprising a pen device body, a cartridge, a plunger, a drive mechanism, and at least one of a lock-out mechanism and a rate-limiting mechanism. The lock-out mechanism is provided through a ratchet engagement between the body and the plunger to restrict plunger movement and to ensure that the required needle puncture depth is realized prior to injection by locking out the injection mechanism from advancing until a specified force is applied to the skin. A rate-limiting mechanism is also provided through a user compressed plunger drive spring to ensure that a specific rate of injection is realized during the injection of a medicament.

Injector device with force lock-out and injection rate limiting mechanisms

An apparatus for storing and dispensing a test strip includes a container configured to store a stack of test strips. The container maintains appropriate environmental conditions, such as humidity, for storing the test strips. An engaging member is disposed in the container and is adapted to contact one test strip of the stack of test strips. An actuator actuates the engaging member to dispense the one test strip from the container. Since one test strip is dispensed at a time, the remaining test strips are not handled by the user. Accordingly, the unused test strips remain free of contaminants such as naturally occurring oils on the user's hand.

Method and apparatus for dispensing diagnostic test strips

A cross connecting device suitable for connecting first and second spinal fixation devices comprises a fixable pivot junction, first and second connection members, and first and second clamps. The fixable pivot junction includes a pivotable joint that is pivotable about a pivot point. The fixable pivot junction also includes a collar configured for fixating the pivot junction. The first and second connection members are connected by the fixable pivot junction such that the fixable pivot junction allows the first and second connection members to be repositioned relative to each other. The first and second clamps are connected to respective ones of the first and second connection members at distal ends of the connection members relative to the fixable pivot junction. The first and second clamps allow the cross connecting device to be clamped on to spinal fixation devices, such as pedicle screws or hooks.

Multi-axial spinal cross connecting device

An apparatus for storing and dispensing a test strip includes a container configured to store a radial array of test strips. The container maintains appropriate environmental conditions, such as humidity, for storing the test strips. The container has a plurality of radially extending slots formed by a plurality of dividing walls, and each slot is sized to receive a single test strip. A rotatably positionable cover is carried by the container for covering the plurality of radially extending slots. The cover includes an opening, which, when the cover rotates, aligns with one of the slots at a time to allow removal of a single test strip located within the respective slot. Accordingly, the unused test strips remain free of contaminants such as naturally occurring skin oils on a user's hand.
