Systems, apparatuses, and methods include an intraocular lens (IOL) cart that may assist with inventory management and may help users identify an IOL for use in a particular surgical application. The IOL cart may include sensors and indicators that provide information to a user and may update IOL inventory automatically whenever the IOL cart is accessed by a user.

An orthopedic implant manufacturing method. The method includes preparing a pre-operative surgical plan for a specific patient, the surgical plan including a three-dimensional image of a patient's joint indicating at least one resection plane, communicating the surgical plan to a surgeon of the patient, and receiving approval of the surgical plan and the resection plane by the surgeon. The method also includes providing automated osteophyte/protrusion removal control for surgeon manipulation, receiving a modified three-dimensional image of a patient's joint indicating an osteophyte/protrusion removal and a recommendation for a corresponding selected orthopedic implant from the surgeon, and requesting manufacture of the selected orthopedic implant.

A method of inserting an intervertebral disc implant into a disc space includes accessing a spinal segment having a first vertebral body, a second vertebral body and a disc space between the first and second vertebral bodies. The method includes securing a first pin to the first vertebral body and a second pin to the second vertebral body, using the first and second pins for distracting the disc space, and providing an inserter holding the intervertebral disc implant. The method also desirably includes engaging the inserter with the first and second pins, and advancing the inserter toward the disc space for inserting the intervertebral disc implant into the disc space, whereby the first and second pins align and guide the inserter toward the disc space.

A sound attenuating apparatus may include a replaceable sound attenuating device and an electronic receiver configured to mate with the replaceable sound attenuating device. The replaceable sound attenuating device may include a sound attenuating material having an embedded sensor element. The sensor element may have a property that corresponds to a type of replaceable sound attenuating device. The electronic receiver may detect the property of the sensor element. A computing device may determine the type of the replaceable sound attenuating device from the property of the sensor element and perform one or more operations based on the type of replaceable sound attenuating device, including audio control, safety warnings, personal attenuation rating determinations, and the like.

A system of prosthetic implants for a total knee replacement procedure is provided. The system includes a tibial component of a knee joint implant, a tibial insert configured to be positioned against the superior side of the platform of the tibial component, a first femoral component of a knee joint implant, and a second femoral component of a knee joint implant.

Medical implants including sensors are described. The implant may have a flexible shell with a base, wherein the plurality of sensors may be incorporated onto and/or into the shell. The plurality of sensors may be distributed at different locations of the shell. Each sensor of the plurality of sensors may be configured to measure one or more parameters such as, e.g., temperature and/or pressure, and may comprise an electromagnetic coil useful for wireless transmission of data. Each sensor may be configured to transmit data at a frequency different from the frequency of one or more of the other sensors, may be configured to transmit data at a time different from a time data is transmitted by one or more of the other sensors, and/or may include a device identifier different from the device identifier of one or more of the other sensors.

An intraocular implant device includes: (1) a lens portion; and (2) a peripheral portion surrounding the lens portion, wherein the peripheral portion includes multiple fiducials including a first fiducial, a second fiducial, and a third fiducial, the first fiducial, the second fiducial, and the third fiducial are positioned in the peripheral portion so that the third fiducial is displaced from a line segment connecting the first fiducial and the second fiducial.

A lens including a posterior surface, an anterior surface, and at least one identification marking on the lens. The at least one identification marking exhibits a first degree of visibility in an ambient lighting condition and a second degree of visibility greater than the first degree of visibility in a lighting condition different than the ambient lighting condition.

A method of inserting an intervertebral disc implant into a disc space includes accessing a spinal segment having a first vertebral body, a second vertebral body and a disc space between the first and second vertebral bodies. The method includes securing a first pin to the first vertebral body and a second pin to the second vertebral body, using the first and second pins for distracting the disc space, and providing an inserter holding the intervertebral disc implant. The method also desirably includes engaging the inserter with the first and second pins, and advancing the inserter toward the disc space for inserting the intervertebral disc implant into the disc space, whereby the first and second pins align and guide the inserter toward the disc space.

A prosthetic heart valve configured to replace a native heart valve and for post-implant expansion and having a valve-type indicator thereon visible from outside the body post-implant. The indicator communicates information about the valve, such as the size or orifice diameter of the valve, and/or that the valve has the capacity for post-implant expansion. The indicator can be an alphanumeric symbol or other symbol or combination of symbols that represent information about the characteristics of the valve such as the valve size. The capacity for post-implant expansion facilitates a valve-in-valve procedure, where the valve-type indicator conveys information to the surgeon about whether the implanted valve is suitable for the procedure and informs the choice of the secondary valve.
