Disclosed is an expandable interbody fusion implant that is configured to have an initial configuration having a first footprint width suitable for being inserted into an intervertebral space and an expanded configuration having a second footprint width that is greater than the first footprint width. The implant may include a first body member and a second body member that is pivotally coupled to the first body member. The implant may be expanded using an inflatable balloon. The implant may be expanded bilaterally such that both body members rotate relative to the other or the implant may be expanded unilaterally such that one of the body members rotates relative to the other.

The present invention relates generally to devices and methods for firmly joining together components of a modular orthopedic prosthesis by securing female to male parts thereof together, and in particular a male part present in a modular component into a correspondingly configured female part (i.e., bore or recess) present in a further modular component thereof. Preferably the male part is tapered, and the bore or recess is correspondingly configured to provide a close tolerance fit therewith. In a preferred embodiment a securement device is used to join the components which securement device includes a heat resistant part or region which shields a heated part from its ambient environment; the securement device is useful in holding a component of an orthopedic prosthesis. In a further preferred embodiment the invention also comprises a heat treatment device which is issued to provide a suitable heat treatment to a component (or part thereof) of a modular orthopedic prosthesis. Methods of utilizing the securement device and the heat treatment device during surgical implantation of modular orthopedic prosthesis is also disclosed.

An automatic machine for processing a tooth by a graft material includes: a body including a power supply supplying power to a controller, which controls the amount of supply solution and operation of a suction pump and a vibrator, and having a receiving space; a receiving container disposed in the receiving space, having a space for keeping a tooth bone graft material, and including a net and a cover having a handle; a cylinder having a space for keeping the receiving container, and inlets and outlets for supplying and discharging the supply solution; a vibrator fastened to the cylinder and generating vibration of 1 to 100,000 VPM; a supplying container supplying the supply solution to the cylinder; and a suction pump discharging solution in the cylinder to a discharging container.

An implant system includes a fixation device that, in turn can include an expandable implant alone or in combination with an auxiliary implant. The expandable implant includes an expandable implant body that is made from an expandable material. The expandable material includes a polymer matrix and an expandable gas source contained within at least a portion of the polymer matrix. The implant system can further include an energy source configured to heat the polymer matrix to a temperature above its glass transition temperature, thereby causing the gas source to expand inside the polymer matrix. The fixation device can further include an insertion instrument configured to implant the fixation device into an anatomical cavity.

A syringe having an energy source disposed therein is disclosed. The syringe is capable of both the delivery and/or aspiration of materials as well as the delivery of an effective amount of various types of energy to a target to produce a desired result. A method utilizing the syringe to administer materials and to deliver energy to the material is also disclosed.

A method for locating a material having thermoplastic properties in pores of bone tissue includes providing a pin having the material having thermoplastic properties and a core, wherein the material having thermoplastic properties is arranged on the circumferential surface of the core constituting an outer region of the pin. An opening is provided in the bone tissue, and the pin is positioned at least partly in the opening. The outer region of the pin is then impinged with mechanical vibration energy for a time sufficient for liquefying at least part of the material having thermoplastic properties, and, in a liquefied state, pressing it into the pores of the bone tissue surrounding the opening. The vibration energy is stopped for a time sufficient for re-solidification of the liquefied material, and then the core is removed.

An articular ball impactor having a heat resistant material used during heat shrink fit process for providing secure fixation of Morse taper components in modular orthopedic implants. The female Morse component of the articular ball is heated by electromagnetic unit providing thermal expansion. Subsequently, itis impacted over the male Morse taper component and then cooled by commonly used sterile irrigation fluid allowing the female Morse component to shrink thus providing considerable compression, fit and significant reduction of micromotion that has been so widely responsible of fretting and mechanical corrosion.

An implant configured to completely replace degenerated or damaged nucleus pulposus in an intervertebral disc. The implant comprises a silicone elastomer shell that is implanted into a void within the annulus fibrosus created by at least partial removal of the nucleus pulposus therefrom. A colloidal suspension of platinum cured silicone-based polymer and carbon nanotubes is injected into the elastomer shell. The colloidal suspension is irradiated with electromagnetic radiation, particularly infrared or near infrared light, to the point that it hardens. The hardened implant becomes a mechanical replacement for the original nucleus pulposus in the intervertebral disc.
