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.

Bioadhesive Compositions which comprise a hydrophobic polymer wherein the concentration of the polymer at the surface of the adhesive is greater than its concentration in the bulk of the adhesive are described; and biomedical electrodes, fixation products and wound dressings containing them.

Apertured fibrous structures and more particularly apertured fibrous structures containing one or more fibrous elements, for example filaments, containing one or more fibrous element-forming materials and one or more active agents that are releasable from the fibrous element when exposed to conditions of intended use, and methods for making same.

The present invention provides porous electroactive hydrogels, the deformation angle of which is controlled by electroactuation, and methods for preparing and using such hydrogels.

MRI-compatible medical instruments and appliances are made using bulk metallic glass alloys. MRI-guided methods include the use of articles that include bulk metallic glass alloys.

In one exemplary embodiment of the invention, a method and computer program include: receiving first and second ciphertexts having first and second data encrypted per an encryption scheme, the encryption scheme has public / secret keys and encryption, decryption, operation and refresh functions, the encryption function encrypts data, the decryption decrypts ciphertext, the operation receives ciphertexts and performs operation(s) on them, the refresh operates to prevent growth of the magnitude of noise for a ciphertext while reducing the modulus of the ciphertext without using the secret key, utilizing a modulus switching technique that involves transforming a first ciphertext c modulo q into a second ciphertext c′ modulo p while preserving correctness, the technique includes scaling by p / q and rounding, p<q; using the operation function(s), performing operation(s) on them to obtain a third ciphertext; and reducing a noise level of the third ciphertext using the refresh function.

Provided herein according to some embodiments is a method of forming a three-dimensional object, comprising: (a) forming a first intermediate object from a first polymerizable liquid; (b) forming a second intermediate object from a second polymerizable liquid; (c) optionally washing said first intermediate and said second intermediate; (d) contacting said first intermediate object to said second intermediate object; and then, (e) solidifying and / or curing a second solidifiable component (e.g., said second reactive component) in each of said first and second intermediate objects while said first and second intermediate objects are in contact with one another to couple said first and second intermediate objects to one another and form said three-dimensional object.

A golf club head has a face portion, a crown portion, a sole portion, a side portion and a hosel portion. Each portion is made of titanium or a titanium alloy. The side portion is formed integrally entirely from its toe side to its back side and its heel side. The side portion and the hosel portion are cast integrally. The face portion, the crown portion and the sole portion are molded separately from one another. The face portion, the crown portion, the sole portion and the side portion are welded integrally so as to form a golf club head. The Young's modulus of the crown portion is lower than any Young's modulus of the face portion, the sole portion, the side portion and the hosel portion.

There is provided a composition comprising a unique polymeric compound that provides a soft, flexible product. There is also provided a unique polymeric tampon applicator that is soft and flexible. When used as a tampon applicator barrel, the barrel is more comfortable and has improved ease of insertion. The polymeric compound primarily comprises a thermoplastic resin and a block copolymer that exhibit unique load, energy and modulus of elasticity properties. The polymeric compound should also include a plasticizer and a compatibilizer / flow modifier, and may include a slip / mold release agent, an antioxidant, and even a pigment. There is also provided a method for making the polymeric compound that will be formed into a product, such as an applicator or applicator barrel in which all of the above ingredients, except for the thermoplastic resin, are combined and formed into soft pellets. The soft resin pellets are then dry blended with pellets of the thermoplastic resin. The mixture of the thermoplastic resin pellets and the soft resin pellets are then melted and injection molded into the desired shape. There is thus provided a method of making a soft, polymeric tampon applicator or tampon applicator barrel.

Multi-layer films that are suitable for packaging and having improved sealing properties are disclosed. Some embodiments may also provide a lower minimum sealing temperature. A soft polymer is blended in a core layer and a tie layer comprising the soft polymer and, optionally, another polymer. A sealable layer is provided on the side of the tie layer opposite the core layer. The multi-layer films may be transparent, contain a cavitating agent, or are pigmented to form an opaque film. Also, the multi-layer film may be metallized or coated with a barrier coating.
