The modular stem component may include a shaft portion, a head, and a sleeve. The shaft portion is configured for receipt within the intramedullary canal of a bone and the head is configured to receive another component of a modular prosthetic system, such as a femoral neck, thereon. In one exemplary embodiment, the head extends radially around at least a portion of the stem and includes a rib defining a flange extending therefrom. The sleeve, which is formed as an independent part of the modular stem component and is made at least partially of a highly porous biomaterial, includes opposing ends and has a bore extending therethrough. The bore is configured to facilitate sliding receipt of the sleeve on the head.

A surrogate multilayered material and manufacturing method thereof includes a first fiber reinforced layer, the first reinforced layer including a crosslinked polymer and fibers, and a second fiber reinforced layer, the second reinforced layer including the crosslinked polymer and the fibers. A foam layer is disposed between the first and second fiber reinforced layers. Opposite faces of the foam layer are in direct contact with the first fiber reinforced layer and the second fiber reinforced layer. The foam layer has a compressive strength of about 3.5 to about 4.5 MPa, when measured as per ASTM-D-1621-73, and a shear strength of 1.50 to about 2.15 MPa, when measured as per ASTM-C-273.

A wrist endoprosthesis (2) for functional replacement of the human wrist, containing a radius component (4) that has a shaft (10) for anchoring in the radius, a head (12), and a first joint surface (16), which is implemented on a distal head face (14), and a carpal component (6) that has a proximal carpal face (22), a distal carpal face (20) and a second joint surface (24) which is formed on the proximal carpal face (22) and interacts with the first joint surface (169) of the radius component (4), characterized in that the carpal component (6) is substantially trough-shaped, in order to at least partially surround the carpal bones. Also, a wrist endoprosthesis (2) that has anti-luxation protection (8), a method for producing wrist endoprostheses (2) and a computer program product.

An implant is provided for use in an ankle joint between reconditioned end surfaces established on a distal end of an upper tibia bone and an opposing lower talus bone. The implant comprises a substantially porous rigid component adapted to be anchored against the upper tibia reconditioned end surface and the lower talus reconditioned end surface. The component defining an opening therethrough. An intramedullary nail is configured to pass through the opening in the component when the nail is driven through the talus and into the tibia.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a cord that is flexible and elongated defining a length. The cord may include a core having a porous surface and a porosity-reducing element on at least a portion of the core.

An annuloplasty ring is provided including a core defining a closed ring and comprising one or more flexible portions, wherein the core is capable of deformation about the flexible portion between a first configuration and a second configuration upon application of a predetermined force; a resilient intermediate layer; and a fabric cover layer.

Embodiments of the present disclosure relate generally to an orbital floor implant (10). One embodiment provides an implant with a first surface that is a fully porous, bone-side layer (16) and a second surface that is a non-porous, orbital content-side layer (18). The implant material itself may be polymeric material throughout, without the need for an embedded mesh or other support matrix. The implant is provided in a pre-shaped configuration and is of a material that allows it to be bent for shaping purposes. An extending tab (12) with eyelet portion/opening (14) can enhance securement options to a patient's bone.

A covered stent for implantation at vascular branches includes a stent body and a membrane fixedly connected to the stent body, wherein micropore areas are provided on the membrane, and the micropore areas have a plurality of micropores which are arranged into an array with pore spacing ranging from 0.2 mm to 2.0 mm. The micropores are capable of allowing blood flow to pass through, and during implantation of the covered stent, the micropore areas are used to identify branch regions of blood vessels and provide an access path for implantation of branch stents, such that the blood flow of nearby branch vessels will not be blocked while treating aortic lesions.

An apparatus is provided for draining aqueous humor from an eye for reducing intraocular pressure. The draining apparatus comprises a tube defining a passage for fluid flow between an inlet end and an outlet end. An outlet assembly contacts the conjunctival layer externally of the eyeball. The outlet assembly comprises a housing in fluid communication with the outlet end of the tube and having an aperture for allowing egress of aqueous humor onto the external ocular surface. A resistive component is disposed in the housing for providing resistance to a flow of aqueous humor. A pair of tabs project outwardly and are adapted to be disposed subconjunctivally for securing the draining apparatus relative to the eyeball.

An orientable intravascular device having a “twelve o'clock” marker on a proximal and distal end for treating an aneurysm, including a packaging catheter with an identical fixed non-round shaped inner lumen, a pusher wire having an occlusion device releasably disposed on the distal end of said pusher wire, preloaded at a fixed circumferential orientation, with corresponding markers on the outside of said packaging catheter, a hub having an inner lumen that is shaped to marry with the outer lumen of the packaging catheter to deliver a delivery wire and occlusion stent in a predicted orientation, and maintaining such orientation as the wire and stent are advanced through said delivery catheter, and while said delivery catheter is withdrawn. Methods of using same are disclosed.
