208 results about "Bony Tissues" patented technology

Bone tissue (osseous tissue) is a hard tissue, a type of dense connective tissue. It has a honeycomb-like matrix internally, which helps to give the bone rigidity.

Implant that can be implanted in osseous tissue and method for producing said implant corresponding implant

A bone implant (10) is implanted in a cavity parallel to an implant axis (I) and without substantial rotation. The implant includes, on an implant portion to be implanted, cutting edges (14), which do not extend in a common plane with the implant axis and are facing toward the distal end of the implant. The implant also includes surface ranges (16) of a material that is liquefiable by mechanical oscillations. The cutting edges (14) are dimensioned such that they are lodged in the cavity wall after implantation. For implantation, the implant is impinged with mechanical oscillations, resulting in the thermoplastic material being at least partially liquefied and pressed into unevennesses and pores of the cavity wall to form a form-fit and / or material-fit connection between implant (10) and cavity wall, when re-solidified. The cutting edges (14) anchor the implant in the cavity wall.

Modeling micro-scaffold-based implants for bone tissue engineering

A new conceptual biomedical method is presented for designing scaffold-based bone implants and using these implants in treating deteriorated bones. These implants have micro-architectural bone structures that are capable of mimicking the stochastic micro-structure as in natural bone bio-mineral structures. Moreover, they can be adapted as specific tailor-made compatible bone-repair mediator implants to be used as effective substitutes for natural damaged bone fracture structures.

Bone fixation plate

ActiveUS20050261690A1Increases magnitudeSmall resistance forceInternal osteosythesisFastenersSet screwSmall patellae
An apparatus for reducing the profile of a bone fixation plate while preventing backing out of screws is disclosed. The plate has at least two openings though which two screws can pass through bony tissue. The apparatus includes at least one section of relief and sections of engagement. As the screw is tightened, it will begin to lag the plate to the bone. When the screw head interferes with the plate at the interference point, there is a slight resistance that insertion forces can overcome. When the screw is advanced further, it snaps into the sliding fit area and is allowed to move freely. The forces that cause the screw to back out from the plate are preferably not strong enough to pass the screw head back past the interference section. At least one of the two openings is configured as an elongated slot to allow the screw to translate in the slot. It may be desirable to include a set screw to help prevent backout.

Shape changing bone implant and method of use for enhancing healing

ActiveUS20140257420A1Block soft tissue infiltrationStores recoverable mechanical energyInternal osteosythesisJoint implantsShape changeBone apposition
Described is a new bone healing method and class of bone fixation implants that change shape once implanted so as to minimize non-healing and speed the bone healing process. The bone fixation method involves shape changing implants that continuously hold the bones in apposition so that a gap does not form. Gaps in time allow non-bony tissue to infiltrate and stop healing. Furthermore, the implants actively compress bone to increase bone mass and strength. Bone cell pressure due to compression and electrical current flow due to bone deformation act to stimulate healing. The new implant designs also provide a scaffolding to conduct bone through the implant and across the healing bone interface. The methods and designs are applicable to but not limited to use for bone screws, plates, staples, rods, cylinders and external fixation devices.
