摘要： A weld cap is configured and dimensioned to interact with a resilient element, e.g., a spring, and a structural member, e.g., an end cap, so as to securely position the spring relative to the end cap. The weld cap functions to distance the welding process and associated welding energy from the spring, thereby avoiding and/or minimizing any potentially undesirable annealing effect associated with securing/welding the spring relative to the end cap. A first weld cap interacts with the spring at a first end region thereof, and a second weld cap interacts with the spring at a second end region thereof, thereby effectively securing the spring with respect to opposed end caps at either end of an elongated spinal stabilization device. Alignment grooves or channels may be provided for orienting or aligning the spring with respect to the end caps and weld caps. The end regions of the spring may also include bend regions that facilitate the assembly process and/or further minimize the freedom of movement of the spring relative to the end cap/weld cap combination. The dynamic stabilization device and associated system provide advantageous clinical results in spinal applications.

摘要： A pedicle screw assembly is provided that includes a pedicle screw and a preloaded set screw. The set screw is preloaded in a threaded, central aperture formed in the head region of the pedicle screw. An interference is advantageously formed on the set screw to prevent dislodgement of the set screw, e.g., during shipment and/or clinical placement of the pedicle screw. An upwardly extending collet is generally formed in the head region of the pedicle screw, the collet being sized to receive a spherical element therearound. Advancement of the set screw relative to the pedicle screw secures the spherical element relative to the pedicle screw. The spherical element typically includes a socket member that cooperates with a dynamic stabilizing member. The pedicle screw assembly and dynamic stabilizing member are advantageously used as part of a spinal stabilization system to provide clinically efficacious results.

摘要： Spinal stabilization devices, systems and methods are provided that include at least one pedicle screw and at least one mechanism that supports three degrees of rotational freedom relative to the pedicle screw. The mechanism may include a universal joint mechanism or a ball and socket mechanism. In the case of the ball and socket mechanism, at least one spherical element is mounted with respect to the at least one pedicle screw and a socket member cooperates with the spherical element. The spherical element and the socket member cooperate to define a dynamic junction that allows the socket member to move relative to the ball element while remaining engaged therewith. The dynamic junction is advantageously incorporated into a spinal stabilization system that includes additional pedicle screw(s), spherical element(s) and socket member(s). The spinal stabilization system may incorporate dynamic stabilizing member(s) to so as to provide clinically efficacious results.

摘要： A surgical implant is provided that includes first and second abutment surfaces between which are positioned a force imparting mechanism. A sheath is positioned between the first and second abutment surfaces, and surrounds the force imparting mechanism. The sheath is fabricated from a material that accommodates relative movement of the abutment members, while exhibiting substantially inert behavior relative to surrounding anatomical structures. The sheath is generally fabricated from expanded polytetrafluoroethylene, ultra-high molecular weight polyethylene, a copolymer of polycarbonate and a urethane, or a blend of a polycarbonate and a urethane. The force imparting member may include one or more springs, e.g., a pair of nested springs. The surgical implant may be a dynamic spine stabilizing member that is advantageously incorporated into a spine stabilization system to offer clinically efficacious results.

摘要： A system and method for effecting multi-level spine stabilization is provided. The system includes a plurality of pedicle screws which are joined relative to each other by elongated members, e.g., rods. At least one of the rods includes a dynamic stabilizing member. The pedicle screw junctions are dynamic, i.e., free relative movement of a socket member is permitted relative to a fixed spherical element. Placement of the spherical element may be facilitated using a guidewire system that includes a guidewire and a tapered guide member. A spine stabilization assembly is also provided that includes an attachment member that includes an opening. At least one spherical element that includes a rod-receiving channel is movably mounted within the opening with three degrees of rotational freedom. The spherical element generally defines an elliptical rod-receiving channel that is deformable to a circular opening to firmly engage a rod positioned therein. Multi-level stabilization systems that combine/mix dynamic and non-dynamic stabilization modalities are also provided. The multi-level spine stabilization system offers efficacious clinical results at least in part due to the inclusion of dynamic stabilizing member(s).

摘要： Spinal stabilization devices, systems and methods are provided that include a stabilization member including a first structural member that mounts to a pedicle screw, a second structural member adjacent the first structural member and that can move away therefrom, a resilient element mounted between the structural members and that elongates to accommodate relative movement therebetween, and a travel-limiting structure mounted between the structural members and that defines and imposes upon the stabilization member a maximum distance by which the first and second structural members may be separated. The travel-limiting structure can include an axially inextensible, laterally flexible elongate element, e.g., wire-rope cable, disposed between the structural members. The resilient element extends between respective first ends of the structural members, while the travel-limiting structure can include terminations at opposite ends of the elongate element and mounted to respective second ends of the structural members opposite the first ends thereof.

摘要： Systems, assemblies and methods for assembling a sheath member with respect to a spinal stabilization device are provided. The disclosed sheath assembly includes at least one connector ring mounted with respect to a sheath member. The connector ring defines an inner wall that shields the sheath member from elements positioned therewithin, e.g., spring members, and generally includes a plurality of radially-spaced notches.

The sheath assembly may be mounted with respect to a spinal stabilization device by crimping, compressing or swaging the connector ring to an underlying structure, e.g., an end cap or associated flange. The internal cavity of the connector ring is generally defined by an inner face, an outer wall and an intermediate apex region. Methods for assembly are also disclosed.

摘要： Spine stabilization devices, systems and methods are provided in which a single resilient member or spring is disposed on an elongate element that spans two attachment members attached to different spinal vertebrae. The elongate element passes through at least one of the two attachment members, permitting relative motion therebetween, and terminates in a stop or abutment. A second resilient member is disposed on the elongate element on an opposite side of the sliding attachment member, e.g., in an overhanging orientation. The two resilient members are capable of applying mutually opposing urging forces, and a compressive preload can be applied to one or both of the resilient members.
