Cortical Rim-Supporting Interbody Device
A central inflatable distractor and a perimeter balloon are inserted into the disc space in uninflated configurations. The central inflatable distractor is then expanded, thereby distracting the vertebral endplates to the controlled height of the central inflatable distractor. The perimeter balloon is then inflated with a curable substance. The perimeter balloon expands as it is filled with the curable substance and conforms to the void remaining in the disc space around the central inflatable distractor, thereby creating a horseshoe shape. Once the flowable material in the perimeter balloon has cured, the central inflated distractor can be deflated and removed. The remaining void (or inner space) is then packed with graft for fusion.
Intersomatic cage, intervertebral prosthesis, anchoring device and implantation instruments
An intersomatic cage, an intervertebral prosthesis, an anchoring device and an instrument for implantation of the cage or the prosthesis and the anchoring device are provided. An intersomatic cage or an intervertebral prosthesis fit closely to the anchoring device, which includes a body of elongated shape on a longitudinal axis, of curved shape describing, along the longitudinal axis, an arc whose dimensions and radius of curvature are designed in such a manner that the anchoring device may be implanted in the vertebral plate of a vertebra by presenting its longitudinal axis substantially along the plane of the intervertebral space, where the anchoring device is inserted, by means of the instrument, through a slot located in at least one peripheral wall of the cage or on at least one plate of the intervertebral disc prosthesis to penetrate into at least one vertebral plate.
Total knee replacement prosthesis with high order NURBS surfaces
A knee replacement prosthesis comprising a femoral component and a tibial component that enable anterior-posterior translation of the femur relative to the tibia and enable the tibia to rotate about its longitudinal axis during flexion of the knee. The femoral component connects to the distal end of a resected femur and includes medial and lateral condyles having distal, articulating surfaces, and a patellar flange having a patellar articulating surface. The tibial component connects to the proximal end of a resected tibia and includes a proximal bearing surface with medial and lateral concavities that articulate with the medial and lateral condyles. The condylar articulating surfaces and the said concavities are substantially defined by non-uniform, rational B-spline surfaces (NURBS).
Trapeziometacarpal joint implant and associated methods
A trapeziometacarpal joint implant includes a body defining a median plane, a metacarpal joint surface, and a trapezium joint surface. A first central region of the metacarpal joint surface is situated on an opposite side of the median plane from a second central region of the trapezium joint surface. The first and second central regions correspond to profiles of a first axial segment and a second axial segment, respectively. The first and second axial segments are one of a cylinder, a cone and a torus and are centered on a first axis and a second axis, respectively, where the first and second axes, as projected on the median plane, are substantially perpendicular to each other.
Device for repairing an intervertebral disc
A device (1, 100) for repairing an intervertebral disc comprising an anchoring body (2, 102), suitable for being advanced into and secured in one of the vertebrae adjacent the intervertebral disc; and a prosthesis (3, 103, 203, 303) attachable in a secure coupling position to the anchoring body (2, 102) and adapted for retaining or replacing the nucleus pulposus in an interior space of an outer annulus of the intervertebral disc, the anchoring body supporting and arranging in the cited coupling position the prosthesis such that the prosthesis is oriented to in a direction toward and through a hole in the outer annulus, the prosthesis comprising at least one active portion (4) adapted to assume and maintain a first placement shape (A) suitable for permitting the active portion to be inserted into and through the hole in the outer annulus during a placement thereof into the interior space of the outer annulus, and at least a second operative shape (B) suitable for at least partially occluding the hole in the outer annulus and/or replacing at least a portion of the nucleus pulposus upon the active portion assuming a placement position in the interior space of the outer annulus.
Low profile intervertebral implant
The present invention is directed to a low profile intervertebral implant for implantation in an intervertebral disc space in-between adjacent vertebral bodies. The intervertebral implant includes a plate preferably coupled to a spacer. The plate is preferably formed from a first material and the spacer is preferably formed from a second material, the first material being different from the second material. The plate is preferably sized and configured so that the plate does not extend beyond the perimeter of the spacer. In this manner, the plate preferably does not increase the height profile of the spacer and the plate may be implanted within the intervertebral disc space in conjunction with the spacer.
METHOD FOR LUBRICATING AN ARTIFICIAL CONTACTING SURFACE
A method for implanting a medical device for implantation in a mammal joint. The method comprising the steps of creating an opening reaching from outside of the human body into the joint, providing said artificial contacting surface to said joint, fixating the artificial contacting surface to the joint, implanting said reservoir in the human body, and lubricating the artificial contacting surface with use of a lubricating fluid contained in said reservoir.
SYSTEM AND METHOD FOR MAKING PERSONALIZED FIBROCARTILAGE IMPLANTS
Systems (500, 1000) and methods (1700) for fabricating a soft tissue implant (100, 400). The methods generally involve: receiving implant data representative of the target implant; determining a planned weaving path for forming the soft tissue implant; and communicating the planned weaving path to an output device.
Spinal Implant With Fluid Delivery Capabilities
A spinal implant that allows for fluid injection of material is disclosed. The implant includes a fitting with a passage and holes that are in fluid communication with the passage. The holes extend through upper and lower surfaces and/or into a central cavity of the implant. The implant allows for material to be introduced into the implant after initial implantation thereof. Methods of implanting the implant are also disclosed.
Silicone nucleus implants
A nucleus implant includes a core (10) arranged inside a nucleus pulposus space (Es) obtained after nucleotomy of the intervertebral disk (Di) and at least one extension (11) penetrating inside at least one channel (Co) formed in the vertebral body of the corresponding vertebra (Va, Vb) to strengthen and ensure a connection between the nucleus implant (1) and the bone body of the vertebra (Va) and/or (Vb) through the diffusion or migration of the viscoelastic material making up the nucleus implant in the cancellous bone of the vertebra.
