  • Publication number: 20150105782
    Abstract: A joint balancing insert with sensors and an actuated mechanism is disclosed. The joint balancing insert is used to balance a joint during arthroplasty surgery, as the sensors provide force, position and angular data relating to the movement of the joint, while the actuated mechanism allows for highly accurate and dynamic adjustments of the joint based on the data from the sensors. Various configurations of actuated mechanisms and sensors may be implemented in the insert to provide for manual or real time control of the insert, and customized interfaces are provided for visualized feedback of adjustments. Sensor data may also be collected and compared with expected or preferred data sets to provide adjustment recommendations and achieve better outcomes based on historical data.

  • Patent number: 8998924
    Abstract: An insertion handle for medical implants includes a handle with an elongate shaft extending therefrom and connection means for the implant disposed at the end of the shaft opposite the handle. The connection means includes a pivotable attachment for the implant that is controlled remotely from the handle. Both angle of the implant with respect to the handle and shaft as well as the attachment may be separately controlled and adjusted. Remote angular adjustment facilitates insertion of implants in to small surgical sites because the orientation of the implant may be repeatedly, remotely adjusted as the implant is inserted. Connectors may also be provided at the engagement surface between the handle and implant in order to provide communication with the implant or surgical site. The connectors also may serve as torque bearing members to avoid the need for separate torque bearing means such as keyways and the like.

  • Patent number: 8992620
    Abstract: A spinal implant which is configured to be deployed between adjacent vertebral bodies. The implant has at least one extendable support element with a retracted configuration to facilitate deployment of the implant and an extended configuration so as to expand the implant and effectively distract the disc space, stabilize the motion segments and eliminate pathologic spine motion. The implant has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it typically passes to be deployed within the intervertebral space. The implant is provided with a locking system having a plurality of linked locking elements that work in unison to lock the implant in an extended configuration. Bone engaging anchors also may be provided to ensure secure positioning.

The implant has at least one extendable support element with a retracted configuration to facilitate deployment of the implant and an extended configuration so as to expand the implant and effectively distract the disc space, stabilize the motion segments and eliminate pathologic spine motion. Angular deformities can also be corrected, and natural curvatures restored. Preferably, the implant has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it typically passes to be deployed within the intervertebral space. The implant is provided with a locking system preferably having a plurality of locking elements to lock the implant in an extended configuration. Bone engaging anchors also may be provided to ensure secure positioning.

  • Patent number: 8740979
    Abstract: Disclosed are methods and devices for restoring or establishing nutrient flow to the nucleus pulposa. An implant comprises a nutrient flow path for extending between a source of nutrients and the nucleus pulposa. The implant is positioned within the patient such that a first end is in nutrient flow communication with a subject nucleus pulposa, and the source end is positioned in nutrient flow communication with a source of nutrients.

  • Patent number: 8696751
    Abstract: A spinal implant which is configured to be deployed between adjacent vertebral bodies. The implant has at least one extendable support element with a refracted configuration to facilitate deployment of the implant and an extended configuration so as to expand the implant and effectively distract the disc space, stabilize the motion segments and eliminate pathologic spine motion. The implant has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it typically passes to be deployed within the intervertebral space. The implant is provided with a locking system having a plurality of linked locking elements that work in unison to lock the implant in an extended configuration.

  • Patent number: 8636689
    Abstract: Pen injection devices (10) and methods of using a pen injection device are disclosed. Pen injection devices include a sterile dual transfer spike assembly (150) including a dual transfer spike defining a fluidic pathway; a first cartridge assembly (12) including a first cartridge (20) containing a first substance; a second cartridge assembly (14) including a second cartridge (30) containing a second substance; a plunger rod (50) translatable in a first direction; and a biasing mechanism (60) configured to bias the plunger rod in a second direction opposite the first direction. Methods of using a pen injection device having a first container, a second container, a plunger rod, and a biasing mechanism include activating the pen injection device, thereby creating a fluidic pathway between the first container and the second container; and translating the plunger rod at least once, thereby transferring a first substance from one container to the other container to mix with a second substance.
