INTRAVASCULAR CUFF
An intravascular cuff acts as a lining between a native vessel and an intravascular prosthetic device. During deployment, the ends of the cuff curl back upon themselves and are capable of trapping native tissue, such as valve leaflet tissue, between the ends. The cuff creates a seal between the vessel and the prosthetic, thereby preventing leakage around the prosthetic. The cuff also traps any embolic material dislodged from the vessel during expansion of the prosthetic.
Shoulder prosthesis and components thereof
The present disclosure relates to a shoulder prosthesis comprising a glenoidal component having a glenoidal articulation surface and a humeral component having a humeral articulation surface, and a separate mobile glenohumeral bearing component comprising a glenoidal bearing surface and a humeral bearing surface arranged on opposite sides of the glenohumeral bearing component. The glenoidal bearing surface contacts in an implanted state the glenoidal articulation surface and/or the humeral bearing surface contacts in an implanted state the humeral articulation surface. At least one of the glenoidal and humeral bearing surfaces is concave. The glenohumeral bearing component is disposed in an implanted state between the glenoidal component and the humeral component. Both the glenoidal and humeral articulation surfaces are convex.
In-situ formed intervertebral fusion device and method
An orthopedic device for implanting between adjacent vertebrae comprising: an arcuate balloon and a hardenable material within said balloon. In some embodiments, the balloon has a footprint that substantially corresponds to a perimeter of a vertebral endplate. An inflatable device is inserted through a cannula into an intervertebral space and oriented so that, upon expansion, a natural angle between vertebrae will be at least partially restored. At least one component selected from the group consisting of a load-bearing component and an osteobiologic component is directed into the inflatable device through a fluid communication means.
Intervertebral spacer that dynamically promotes bone growth
A dynamic intervertebral spacer includes a ring which is split on an anterior portion. A posterior portion of the ring acts as a torsion spring. After implantation, the ring is able to act as a spring between superior and inferior vertebral bodies, thus allowing dynamic bone growth in fusion procedures.
Hip joint device and method
A medical device for implantation in a hip joint of a human patient, the natural hip joint having a ball shaped caput femur as the proximal part of the femoral bone with a convex hip joint surface towards the center of the hip joint and a bowl shaped acetabulum as part of the pelvic bone with a concave hip joint surface towards the center of the hip joint. The medical device comprising; an artificial caput femur, comprising a convex surface towards the center of the hip joint. The artificial convex caput femur is adapted to, when implanted: be fixated to the pelvic bone of the human patient, and be in movable connection with an artificial acetabulum surface fixated to the femoral bone of the patient, thereby forming a ball and socket joint. The medical device further comprises a fixation element comprising a fixation surface adapted to be in contact with the surface of the acetabulum and adapted to fixate the artificial convex caput femur to at least the acetabulum of the pelvic bone.
ORTHOPEDIC SURGICAL IMPLANT DEVICE WITH POROUS MATERIAL AND FLUID CHANNELS FOR CLEANING THE POROUS MATERIAL
This disclosure describes a surgical implant device comprising a body that includes a porous material forming at least a portion of the body, wherein the porous material is configured to promote bone ingrowth and is porous to a fluid. In addition, one or more fluid channels are formed in the body. The one or more fluid channels are arranged to define a fluidic path that exits into the porous material.
GLENOID IMPLANT HAVING MULTIPLE SECTIONS OF DIFFERING DIAMETERS
Disclosed are prosthesis systems and methods that provide ways by which the articulating surfaces of the implant can be exchanged such that the anatomic surfaces can be converted to reverse surfaces, while not exchanging the fixation components. Also disclosed herein are methods by which the surgeon can implant an inset anatomic articulating glenoid implant whereby at a later date, can remove the anatomic articulating surface and replace it with a reverse articulating surface such that the primary means of fixation remains well fixed in the glenoid fossa at the moment of articular exchange.
Intervertebral prosthesis
An intervertebral prosthesis for insertion between adjacent vertebrae includes upper and lower prosthesis plates locatable against respective vertebrae and having opposing, concavely curved recesses therein, and a core located between the plates. The core has opposed, convexly curved surfaces received in the recesses of the plates to allow the plates to slide in articulated manner over the core. The opposed surfaces of the core and the recesses of the plates have cooperating spherical curvatures. The recess of each plate surrounds a locating peg projecting centrally from the base of the recess and is bounded by an annular rim, such that the annular rims of the plates are arranged to contact one another at a predetermined limit of sliding movement of the plates over the core. The peg locates loosely in an opening located centrally in a curved surface of the core, whereby the plates can slide over the core in all directions while the peg holds the core captive.
Intervertebral prosthesis
An intervertebral prosthesis for insertion between adjacent vertebrae includes an upper plate, a lower plate and a core. The core is retained between the upper and lower plates by a retention feature in the form of central projections on the plates and a corresponding opening in the core. The retention feature is designed to allow the plates to slide over the upper and lower surfaces of the core in the anterior/posterior direction and in the lateral direction and to allow the plates to rotate with respect to each other and the core. The retention feature is also designed to prevent contact between the first and second plates during sliding movement of the plates over the core.
Standalone interbody implants
Stand-alone interbody fusion devices for engagement between adjacent vertebrae. The stand-alone interbody fusion devices may include frames and one or more endplates coupled to the frame. The frame may be configured and designed to provide the apertures which are designed to retain bone fasteners, such as screws or anchors, and secure the implant to the adjacent vertebrae.
