The present invention relates to a system and method for spinal disc replacement surgery via a lateral approach. The invention also relates to a spinal disc replacement device that is designed to be inserted via the lateral approach disc replacement surgery. The invention further relates to tools used for the spinal disc replacement surgery via the lateral approach.

A surgical implant and a surgical kit. The surgical implant having a body for contacting and supporting adjacent vertebrae. The body has a) opposing superior and inferior surfaces with or without corrugations, b) recesses formed in the opposing superior and inferior surfaces within a peripheral boundary of the body, and a recess-fill material (which preferably promotes osseointegration) disposed in the recesses.

Orthopedic devices are described including polymer compositions used to make the devices. The polymer composition contains a polyoxymethylene polymer in combination with various additives that prevent against agglomerations and spotting even when the composition contains significant amounts of coloring agents and/or waxes. In addition, the polymer composition has reduced formaldehyde emissions and excellent thermal stability properties.

The present invention is an internal osseointegrated transfemoral amputee implant device and related methods. The device is designed to restore the enclosed nature of the bone marrow system which is disrupted by amputation, plus provide a pressure tolerant (weight-bearing) surface and mechanical anchoring for the iliotibial band.

The invention relates generally to generation of biomimetic scaffolds for bone tissue engineering and, more particularly, to multi-level lamellar structures having rotated or alternated plywood designs to mimic natural bone tissue. The invention also includes methods of preparing and applying the scaffolds to treat bone tissue defects. The biomimetic scaffold includes a lamellar structure having multiple lamellae and each lamella has a plurality of layers stacked parallel to one another. The lamellae and/or the plurality of layers is rotated at varying angles based on the design parameters from specific tissue structural imaging data of natural bone tissue, to achieve an overall trend in orientation to mimic the rotated lamellar plywood structure of the naturally occurring bone tissue.

An acetabular spacer device, of a type that is temporary and disposable, adapted to be implanted in use in a bone cavity placed at a joint of the human body, such as a hip or shoulder joint, has a cup-like shape, substantially hemispherical, and includes a first convex surface, adapted to be positioned at the bone cavity, a second concave surface, which defines a cavity, further includes at least one pharmaceutical or medical substance, such as at least one antibiotic, adapted to treat during use an ongoing infection in the bone cavity.

Provided for herein, in several embodiments are implants and methods of using same to repair damaged or defective soft tissue. In several embodiments, the soft tissue comprises cartilage within a joint space. In several embodiments, the implants provided for comprise a stimulating region and an anchoring region. In several embodiments, the implants are spherical. A discontinuity between a surface of the implant and the surrounding cartilage advantageously facilitates implant placement and stimulation of generation of fibrous tissue, and subsequently new cartilage.

A motion preserving spinal implant is presented for use in placement between intervertebral space for total replacement of a degenerated spinal disc. The motion preserving spinal implant has a pair of end plates sandwiched around an inner core and an outer core, with the inner core being concentrically positioned within the outer core. The outer core encapsulates the inner core and provides adequate sealing of the inner core while maintaining flexibility and elasticity to advantageously support physiological movements. The inner core is constructed of an elastomeric material and acts as a solid diaphragm in order to resist and withstand localized compression and other forces. The end plates provide anchoring and fusion with adjoining vertebra and hold the inner and outer cores in place. The motion preserving spinal implant restores the normal height and natural function of the degenerated spinal disc and preserves the natural motion of the spine.

Techniques and devices for improved breast surgeries are provided. The devices can include tissue matrix and synthetic meshes for surrounding breast implants or tissue expanders to provide improved implant outcomes for pre-pectoral implantation or other implantation techniques.

At least a portion of fabrics for use in medical devices is formed from polymeric materials. The fabrics may be uncoated, partially coated or fully coated with one or more layers of a polymer. The fabrics may be used for the leaflets and/or cuffs of prosthetic heart valves and as a component of other medical devices.
