An implantable medical device includes a porous metal foam or foam-like structure having pores defined by metal struts or webs wherein the porous structure has directionally controlled pore characteristics. The pore characteristics controlled include one or more of the metal structure porosity, pore size, pore shape, pore size distribution and strut thickness. The pore characteristics may vary in one or more directions throughout the structure. Preferably the pore characteristics are controlled to match the porous metal structure to various mechanical and biological requirements of different regions of the structure in order to optimize aspects of the implants performance and may vary not only over the surface of the porous structure but through the depth of the porous structure. The thickness of the porous metal structure may also be modified to establish a thickness profile that optimizes mechanical and biological requirements of the implants performance. Acetabular cup embodiments of the invention are described. Various methods of manufacturing implants having directionally controlled pore characteristics are described.

This invention is directed to the field of medical implants, and more specifically to biodegradable injectable implants and their methods of manufacture and use. The injectable implants disclosed herein comprise glycolic acid and bio-compatible / bio-absorbable polymeric particles containing a polymer of lactic acid. The particles are small enough to be injected through a needle but large enough to avoid engulfment by macrophages. The injectables of this invention may be in a pre-activated solid form or an activated form (e.g., injectable suspension or emulsion).

The present invention relates to biscarbodiimides, thiourea derivatives, urea derivatives, and cross-linked hyaluronan derivatives having at least one intramolecular disulfide bond, and methods of preparation thereof. The invention also includes thiolated hyaluronan derivatives and salts thereof having at least one pendant thiol group or a modified pendant thiol group, and methods of preparation thereof. An example of a modified pendant thiol group is a sulfhydryl group linked to a small molecule such as a bioactive agent, for example a drug or pharmaceutically active moiety. A hyaluronan derivative having a sulfhydryl group linked to a pharmaceutically active moiety is useful as a sustained or controlled release drug delivery vehicle. Compositions containing the hyaluronan derivatives of the invention can reversibly viscosify in vivo or in vitro, in response to mild changes in condition, and are thus useful in ophthalmic surgery and in tissue engineering.

The present invention concerns a high melt strength propylene polymer or copolymer suitable for manufacturing foams and thermoformed product exhibiting a melt strength of at least 3 g and comprising a high molar mass portion and a low or medium molar mass portion. The polymers are produced by subjecting propylene and optionally other olefins to polymerization in a plurality of polymerization reactors connected in series, employing different amounts of hydrogen as a molar mass modifier in at least two of the reactors, and carrying out the polymerization reaction in the presence of a catalyst system capable of catalyzing the formation of a high molar mass polymerization product having a MFR2 of less than 0.1 g / 10 min and a low or medium molar mass polymerization product having a MFR2 of more than 0.5 g / 10 min.

The invention provides a touch control display panel. The touch control display panel comprises a substrate, a thin film transistor array, an organic light emitting unit, a thin film packaging layer and a touch sensing electrode, wherein the thin film transistor array, the organic light emitting unit and the thin film packaging layer are sequentially stacked on the substrate, and the touch sensing electrode is arranged on the side, away from the organic light emitting unit, of the thin film packaging layer. The touch control display panel comprises a display area and a non-display area surrounding the display area. The non-display area is provided with a first dam surrounding the display area, and a second dam surrounding the first dam. The non-display area comprises a binding area and frame areas located on the two sides of the binding area, and at least the binding area, the portion between the first dam and the second dam and the side, close to the display area, of the first dam are filled with organic materials. Touch control electrode lead breakage caused when the touch control electrode leads pass through uneven dam areas is avoided. Besides, the organic materials have good elasticity, can relieve and protect stress accumulation of the touch control electrode leads when the display panel is bent. The provided touch control display panel is more applicable to flexible display.

Building panels 1, 1′ provided with a mechanical locking system including a tongue 30, at first edge 4a of a first building panel 1, cooperating with a tongue groove 20, at a second edge 4a of an adjacent second building panel 1′, for vertical locking of the building panels and a method for producing such building panels 1, 1′. The method includes the step of forming the tongue of material of the first edge. The insertion groove (40) may have a sidewall (60) at a third edge (5a), which is adjacent the first edge (4a), and may be open at a fourth edge (5b), which is opposite the third edge.
