A reader for medical implants includes an antenna and a transceiver chip connected with the antenna. The transceiver chip includes a power amplifier and a resistor. The power amplifier is connected with a reference voltage through the resistor and configured to produce a first communication signal with high frequency and transmit the first communication signal to the medical implants through the antenna. The medical implant receives the first communication signal and produces a second communication signal according to variation of parameters of the medical implant. The antenna is configured to receive the second communication signal. The power amplifier is further configured to vary a DC current which flows through the resistor according to the second communication signal and read signals of the medical implant according to variation of the DC current. The power amplifier is further configured to modulate the second communication signal into a low frequency signal.

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.

A prosthesis system comprises plates that can be positioned against vertebrae and a selected resilient core that can be positioned between the plates to allow the plates to articulate. The selected resilient core can be chosen from a plurality of cores in response to patient characteristics, such as age and/or intervertebral mobility, such that the prosthesis implanted in the patient is tailored to the needs of the patient. The plurality of cores may comprise cores with different resiliencies, and one of the cores can be selected such that the upper and lower plates articulate with the desired shock absorbing resiliency and/or maximum angle of inclination when the one selected core is positioned between the plates.

An orthopedic device includes a femoral implant having a non-custom internal bone engagement surface. The femoral implant includes at least nine parameters adjusted preoperatively to correspond to a specific patient. The parameters can include patient-specific lengths, such as, for example, medial and lateral condyle widths and notch height, and patient-specific medial and lateral angles.

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.

The invention relates to a method for the production and forgery-proof authentication of medical devices by using a nucleic acid having a known partial sequence, the method comprising the following steps: (i) producing a medical device (MED) having a permanent marking (PM), wherein the medical device (MED) comprises a polymer (P) with the permanent marking (PM) and the permanent marking (PM) contains at least one nucleic acid (NUK) with a known partial sequence (TSEQ); (ii) isolating the permanent marking (PM); and (iii) authentication of the medical device (MED) by detection of the at least one known partial sequence (TSEQ).

In various embodiments, an intervertebral disc prosthesis is provided. The prosthesis may be provided with an insertion adapter, such as a head, holder, or other carrier of the prosthesis. The insertion adapter may be configured to retain the prosthesis and to engage an insertion tool body. In various embodiments, the prosthesis and the insertion holder are provided in a sterile pack, with the prosthesis components and the insertion holder sterilized and packaged in one or more types or layers of sterile packaging. In various other embodiments, the prosthesis and an insertion tool are provided in a sterile pack, with the prosthesis components and the insertion tool sterilized and packaged in one or more types or layers of sterile packaging.

A system and method for transmitting implant data includes an orthopedic implant, a wireless receiver, and a processing circuit electrically coupled to the wireless receiver. The orthopedic implant is configured to transmit implant identification data and implant sensor data to the wireless receiver in response to a power signal. The orthopedic implant may transfer the data over, for example, a wireless network. The processing circuit receives the implant identification data and the implant sensor data from the wireless receiver and is configured to retrieve patient-related data from a database based on the implant identification data. The processing circuit may also be configured to update a patient queue, assign a patient room to a patient, and/or transmit the patient-related data and the implant sensor data to a client machine located in the patient room.

An orthopedic device includes a femoral implant having a non-custom internal bone engagement surface. The femoral implant includes at least nine parameters adjusted preoperatively to correspond to a specific patient. The parameters can include patient-specific lengths, such as, for example, medial and lateral condyle widths and notch height, and patient-specific medial and lateral angles.

A heart prosthesis that includes at least one information marker and methods of using the heart prosthesis are disclosed. The at least one information marker can indicate any suitable information associated with the heart prosthesis, e.g., one or more of a manufacturer, type, model, feature, size, and date. And the heart prosthesis can include any suitable prosthesis, e.g., a prosthetic heart valve or an annuloplasty prosthesis.
