A knee spacer device configured to be implanted temporarily at the joint area between the tibia and femur of a patient to replace an infected joint prosthesis and to maintain the size or spaces of the patient's joint area before implanting a new prosthesis includes a tibial unit and a femoral unit.

Disclosed herein are implantable dual-valve devices having first and second valve structures, a connector coupled to the structures, and first and second sealing members coupled on each side of the device, along with related methods of deploying such devices.

A method of manufacturing a patient-customized tibial element for use in artificial knee joint surgery. A tibial element data table regarding sizes of proximal tibial prostheses is formed. Standard molds able to cover the tibial element data table are manufactured. A standard mold is selected from the standard molds in order to manufacture a patient-customized proximal tibial prosthesis. A proximal tibial prosthesis fitting a patient is formed using the selected standard mold.

A tibial implant having a stem and a tibial sleeve. The tibial sleeve having a proximal end and a distal end, where the proximal end includes an annular male portion. The tibial implant also includes an offset ring having a central bore that is offset from the center of the offset ring, where the bore of the offset ring receives the annular male portion of the tibial sleeve. The tibial implant further includes a base plate having a proximal end and a distal end, where the distal end of the base plate forms a female portion, and the female portion receives both the offset ring and the male portion of the tibial sleeve.

The present application relates to novel intraocular devices and their use in surgical techniques, as well as the novel surgical methodology achieved from their use.

Methods of selecting and implanting prosthetic devices for use as a replacement meniscus are disclosed. The selection methods include a pre-implantation selection method and a during-implantation selection method. The pre-implantation selection method includes a direct geometrical matching process, a correlation parameters-based matching process, and a finite element-based matching process. The implant identified by the pre-implantation selection method is then confirmed to be a suitable implant in the during-implantation selection method. Methods of implanting meniscus prosthetic devices are also disclosed.

Tissue anchors, kits that include a tissue anchor, and methods of anchoring tissue to a bone are described. An example embodiment of a tissue anchor includes a screw and a stem releasably attached to the screw. The screw defines a first opening, a second opening, and a lumen that extends from the first opening to the second opening. A portion of the stem is sized and configured to be received within the lumen defined by the screw.

A transdermal intraosseous device for coupling a bone stump to an external prosthetic device includes a bone fixator, an external connector and a plurality of modular interface components. The bone fixator includes a proximal portion configured for anchoring into the bone stump of the patient and a distal portion including a base collar configured for subcutaneous implantation. The external connector has a distal portion for coupling to the external prosthetic device and a proximal portion for coupling to the distal portion of the bone fixator. Each interface component can be removably coupled to the base collar and has different size and shape to provide a surgeon-selected transition between the prosthetic device and the patient's skin.

Various embodiments of craniofacial implants, surgical instruments, and techniques are described to provide improved surgical results.

Methods for the rapid retraction of trans-catheter heart valve delivery systems are provided. A rapid retraction trans-catheter heart valve delivery system comprises a catheter based delivery system. The delivery system has internal mechanisms that allow for the controlled deployment of a heart valve prosthesis, as well as mechanisms that allow for quickly closing the catheter once the heart valve prosthesis has been implanted. This rapid retraction ability allows for reduced procedural durations and thus reduced risk to the patient.
