Abstract: The present inventions relate to a system and method for altering growth of bones. More precisely, the system is an orthopedic apparatus for correcting rotational deformities and limb length discrepancies. A system of cable-couplings with linking members is used, the linking members being posts or screws traversing bones. Due to the flexibility and adaptability of the system and its components, the cable-coupling members may be installed at varying angles and locations while allowing for growth arrest or rotational corrections of said bones. A method to limit growth using cable-couplings systems is also provided.

Abstract: Embodiments of an orthopedic apparatus and method for using the orthopedic apparatus to correct rotational bone deformities are disclosed. Embodiments of the orthopedic apparatus include a stationary segment having a fixed portion engaged to a first bone portion and a track portion engaged to a mobile segment that is engaged to a second bone portion separated by the first bone portion by a growth plate such that the mobile segment migrates over time from a first position along the stationary segment to a second position along the stationary segment in such a way that torsional growth and correction of an angular deformity are promoted.

Abstract: A screw assembly and method developed for the fixation of femoral neck fractures without interruption of the growth process is disclosed. The screw assembly includes a male component that is attached to the lateral cortex and a female component that is attached at the proximal epiphysis. Anchorage of the components is achieved through screw-type fixation. The screw has a built-in feature that allows for free extension of its length as the fracture site or the slipped capital physeal plate heals and normal patient growth continues. Stable fixation and rotational stability are created at the fracture (slip) site while avoiding compression forces, thus avoiding premature closure of the physeal plate.

Abstract: A blade-plate assembly for performing an osteotomy procedure is disclosed. The blade-plate assembly may include a modular blade component configured to be coupled to either a Varus plate component or a Valgus plate component when performing the osteotomy procedure. In some embodiments, the modular blade component includes a support portion and a blade portion that extends outwardly in perpendicular relation to the support portion. The blade portion defines a channel configured to permit passage of a guide wire when performing the osteotomy procedure.

Abstract: Embodiments provide an orthopedic apparatus that can include a tether member that is capable of engaging a bone using a plurality of coupling members. In some aspects, the tether member can include a central band that may be disposed between a distal member and a proximal member. The proximal member can define a proximal aperture and the distal member can define a distal aperture. Moreover, the distal member can be configured to be engaged to a fixed segment of the bone using at least one of the coupling members and the proximal coupling member can be configured to be engaged to a mobile segment of the bone using at least one other coupling member.

Abstract: A medical device delivery system for remotely deploying a stent or similar medical device is disclosed. The medical device delivery system includes a delivery device having a handle engaged to an elongated barrel with a puller arrangement attached to an elongated outer catheter defining a distal end engaged to a catheter tip that collectively encapsulates the medical device. The handle includes a trigger actuator operatively engaged to a drive mechanism with a lead screw that drives the puller arrangement along the barrel. During deployment, the trigger actuator is actuated by the user, which activates the drive mechanism and rotates the lead screw for moving the puller arrangement to automatically deploy the medical device. In manual operation, the user disengages the lead screw from the puller arrangement and manually moves the puller arrangement toward the handle to manually deploy the medical device rather than actuate the trigger actuator.
