  • Publication number: 20130158575
    Abstract: A surgical scalpel, scalpel instrument and/or scalpel system (collectively, scalpel), is configured for use in a transverse carpal ligament surgical procedure. The scalpel evaluates an incision path with respect to a nerve in the incision path, and performs the incision if appropriate. The scalpel emits a signal through a potential incision path through tissue captured by the scalpel. The scalpel utilizes the emitted signal to determine whether a nerve is in the incision path. The surgical instrument includes a retractable blade. Evaluation includes determining whether a nerve is present before incision and/or evaluating whether the target tissue has been appropriately captured. A warning is provided when a nerve is in the incision path and/or the captured target tissue is inappropriate. The surgical instrument disables extension of the blade when a nerve is in the dissection path and/or the captured target tissue is inappropriate.

  • Patent number: 8460390
    Abstract: A trial implant system includes a stem component and an articulating component forming part of a joint of a patient. A trial mounting assembly mounts the articulating component to the stem component at variable relative angular positions. The trial mounting assembly includes an expandable ball portion and an expansion element configured to expand the ball portion upon rotation of the expansion element. In an expanded state, the ball portion contacts a cavity within the stem at three points of contact to fix the center of rotation of the ball portion at a pre-determined location within the stem. The stem cavity defines an inwardly projecting circumferential lip that bears against ball portion as it expands to ensure the three-point contact.

  • Patent number: 8444698
    Abstract: A joint prosthesis includes a bone engaging portion, such as a stem, and articulating component, such as a humeral head, and an insert component that supports the articulating component and is removable from the stem. A mating component mates with the humeral head and is configured to engage the insert component at adjustable angles according to the anatomy of the patient's joint. In a revision surgery, the stem remains within the patient's bone while the insert component is removed with the mating component and humeral head fixed to the insert component. A new insert component may be prepared with the mating component and humeral head oriented to replicate the angular orientation of the previous prosthesis. The new insert component is then mounted within an insert cavity in the implanted stem and rigidly fastened to complete the revision.
