Additionally, the AR system can include a plurality of inertial measurement units, where a respective inertial measurement unit is attached to each respective camera. Optionally, the AR system can be configured to display image data (e.g., medical image data) registered and superimposed on the real-time image as seen by the user of the AR system.

Abstract: A method and process for at least partially forming a medical device. The present invention is generally directed to a medical device that is at least partially made of a novel alloy having improved properties as compared to past medical devices. The novel alloy used to at least partially form the medical device improves one or more properties (e.g., strength, durability, hardness, biostability, bendability, coefficient of friction, radial strength, flexibility, tensile strength, tensile elongation, longitudinal lengthening, stress-strain properties, improved recoil properties, radiopacity, heat sensitivity, biocompatibility, improved fatigue life, crack resistance, crack propagation resistance, etc.) of such medical device.

Abstract: A system and method is provided for estimating orientation and position of surgical instrumentation or tools relative to a patient's bone structure. The system and/or method may include registering an axis and/or plane associated with a patient's bone. The system and/or method may further include receiving, from magnetic and orientation sensors, information indicative of orientation and position of the surgical instrument or tool relative to the registered axis and/or plane.

Abstract: A bone fixation screw device for implantation into a bone of a patient is disclosed. The screw device includes a screw body having an outer surface. A plurality of outer screw threads extends around the outer surface of the screw body. A plurality of apertures or passages is defined through the outer surface. A plurality of anchors can extend out of corresponding apertures in the screw body. The anchors can be inserted into a patient's bone to further fixate and purchase the bone screw within the patient's bone. The screw body can include an inner cavity, the plurality of apertures each being open to the inner cavity. The anchors can extend out of corresponding apertures from the inner cavity.

Abstract: Interbody fusion devices and related methods of manufacture are described herein. An example interbody fusion device can include a plurality of vertebral endplates, and a body extending between the vertebral endplates. The body and the vertebral endplates can define an internal cavity. Additionally, each of the vertebral endplates can include a lattice structure and a frame surrounding the lattice structure, where the lattice structure being configured to distribute load. Each of the vertebral endplates can also include a plurality of micro-apertures having an average size between about 2 to about 10 micrometers (?m), and a plurality of macro-apertures having an average size between about 300 to about 800 micrometers (?m).

Abstract: A medical device for insertion and expansion in a body passageway. The medical device includes an inflatable device such as a balloon that is designed to be inflated and deflated while positioned in the body passageway. The inflatable device is inflatable by inserting a fluid in an internal cavity of the inflatable device. The inflatable device includes an outer surface that has a surface structure or micro-surface structure which is designed to at least partially penetrate into an inner wall of the body passageway when the inflatable device is inflated.

Abstract: A method and process for at least partially forming a medical device which improves the physical properties of the medical device.

Abstract: A joint monitoring system for measuring performance parameters associated with an orthopedic articular joint comprises a force sensing module and an inertial measurement units. The sensing module comprises a housing that engages with the joint articular surface having a medial portion and a lateral portion. The sensing module also includes a first and second set of sensors disposed within the housing. The first set of sensors are mechanically coupled to the medial portion of the particular surface and configured to detect information of a force incident upon the medial portion of the articular surface. The second set of sensors are mechanically coupled to the lateral portion of the articular surface and configured to detect information a force incident upon a lateral portion of the articular surface. The inertial measurement unit is configured to detect an orientation of at least one of a first and second bone of a knee joint.

Abstract: A knee balancing system for measuring performance parameters associated with an orthopedic articular joint comprises a force sensing module and one or more inertial measurement units. The force sensing module comprises a housing that includes an articular surface having a medial portion and a lateral portion, each of which is substantially mechanically isolated from the other. The force sensing module also includes first and second sets of sensors disposed within the housing. The first set of sensors is mechanically coupled to the medial portion of the articular surface and configured to detect information indicative of a first force incident upon the medial portion of the articular surface. The second set of sensors is mechanically coupled to the lateral portion of the articular surface and configured to detect information indicative of a second force incident upon a lateral portion of the articular surface.

Abstract: A method for estimating leg length and offset, comprises registering an anatomic coordinate frame associated with a patient's pelvis. The method also comprises measuring a first position of a femur relative to the patient's pelvis. The method further comprises receiving, from magnetic and orientation sensors, information indicative of a change in a position of the femur relative to the pelvis of the patient's pelvis. Alternatively, the method further comprises receiving, from light and orientation sensors, information indicative of a change in a position of the femur relative to the pelvis of the patient's pelvis. The method also comprises determining at least one of a leg length and an offset based on the first position and the change in position.
