STEMLESS METAPHYSEAL HUMERAL IMPLANT

A stemless prosthetic shoulder joint may include a prosthetic humeral head and a stemless base. The stemless base may include a collar and an anchor extending from the collar intended to anchor the base into the proximal humerus. The anchor may include various features to enhance the fixation of the base, including hooks, threads, and/or expandable members that may be transitioned from a contracted insertion condition to an expanded implanted condition once the base is positioned in the bone. The anchor and/or collar may also include additional features to enhance fixation, such as geometries and surface features to enhance fixation to bone. The anchor may include a plurality of chisel slots to facilitate removal of bone during a revision surgery.

20250090344 · 2025-03-20 · ·

A height-adjustable spinal fusion cage including a first end plate and a second end plate, a distal movement block fixed to be relatively movable to a dove-tail groove formed at a distal end of each of the first end plate and the second end plate, a proximal movement block fixed to be relatively movable to a dove-tail groove formed at a proximal end of each of the first end plate and the second end plate, an adjusting member rotatably fixed to the proximal movement block and screw-coupled to the distal movement block to adjust a distance between the distal movement block and the proximal movement block, and a vertical guide portion formed to be disposed at the first end plate and the second end plate and provide support for a load in a longitudinal direction or width direction of the first end plate and the second end plate.

LASER-PRODUCED POROUS STRUCTURE
20170014235 · 2017-01-19 ·

The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.

Implants having improved mechanical properties and/or degradation profiles, kits including such implants, and methods of producing and using the same.

Medical device suitable for location in a body lumen

A stent (1) for deployment in a blood vessel which is movable between an unloaded straight cylindrical state and a loaded curved state. The stent (1) is bendable between a first loaded configuration when the blood vessel is in the unloaded state, and a second loaded configuration when the blood vessel is in the loaded state. The stent (1) has an unloaded configuration which is intermediate the first loaded configuration and the second loaded configuration. Because of the unloaded configuration of the stent (1), the degrees of deformation which the stent (1) undergoes are minimized leading to minimized strains, increased fatigue life, and reduced risk of fracture.

MEDICAL DEVICE BASED ON BIOCERAMICS, ITS USE AS A SYNTHETIC BONE GRAFT AND PROCESS FOR THE PREPARATION THEREOF

The present invention relates to a medical device manufactured using the additive manufacturing process (3D printing). It is a medical device used preferably as a bone graft composed of a porous structure based on bioceramics based on -tricalcium phosphate (-TCP) or hydroxyapatite, which may or not contain nanostructures in its composition, for example: carbon nanostructures (graphene, graphene oxide, reduced graphene oxide, carbon nanotubes, etc.) and, in preferred embodiments, stem cells and polymeric membrane. Also, the present invention relates to the use of this device as a bone graft and the process of preparing this device.

Implants for use in total ankle replacement

Implants and devices for maintaining, correcting and/or fusing joint deformities are disclosed. The implant includes a first member, a second member, and an insert with a top surface and a bottom surface. The top surface of the insert couples to the first member and the bottom surface of the insert engages the second member. The top surface includes an anterior articulating surface with an anterior-medial sagittal radius and an anterior-lateral sagittal radius that is greater than the anterior-medial sagittal radius and a posterior articulating surface with a posterior-lateral sagittal radius and a posterior-medial sagittal radius that is greater than the posterior-lateral sagittal radius.
