This invention provides novel nanofiber enhanced surface area substrates and structures comprising such substrates for use in various medical devices, as well as methods and uses for such substrates and medical devices. In one particular embodiment, methods for enhancing cellular functions on a surface of a medical device implant are disclosed which generally comprise providing a medical device implant comprising a plurality of nanofibers (e.g., nanowires) thereon and exposing the medical device implant to cells such as osteoblasts.

An ultrasound catheter adapted for accessing small vessels in the distal anatomy is disclosed. The ultrasound catheter comprises an elongate tubular body formed with a delivery lumen. The flexibility and dimensions of the tubular body allow access to the distal anatomy by advancement over the guidewire. An ultrasound radiating member is provided along the distal end portion of the tubular body for emitting ultrasound energy at a treatment site. A drug solution may also be delivered through the delivery lumen and out an exit port to the treatment site.

An LED system that simulates bare or exposed neon in appearance. The curvilinear LED light source comprises a rigid, formable light guide having a generally circular cross-section and a flexible LED light engine. The light guide is made of a material or materials that can be heated and formed into a desired shape. The light guide retains the desired shape upon cooling. The flexible light engine is inserted into a groove in the light engine.

To more accurately control insertion of penetrating instruments (e.g., trocars, needles, or the like) into a body cavity, organ, or potential space, an accelerometer is coupled to the penetrating instrument. The accelerometer may by employed to measure or detect the sudden lack of resistance which occurs when the penetrating instrument penetrates to a predetermined depth (e.g., through the abdominal cavity, vein, or outer bone) in a more accurate and reliable way instead of practitioners' subjective feeling. An acceleration sensor (i.e., accelerometer) coupled to the penetrating instrument (e.g., trocar or the like) may transform the physical variable ‘resistance change’ into an electronic signal that is then processed in an electronic circuit, and finally triggers an audible/visible alarm and/or feeds an actuating mechanism to control movement of the penetrating instrument.

Compositions and methods in which dry-committed fibers are substantially homogeneously dispersed throughout a fibrous composition. The fibrous composition is characterized as having sufficient yield stress and viscosity such that the shearing forces from the mixing apparatus are effectively transferred down to the fiber level. This is accomplished by means of an appropriate thickening agent, e.g, gelatinized starch. The dry-committed fibers are exemplified by flash dry fibers or fibrous sheets that have been cut or torn into fragments less than 2 cm across. Providing fibers that have been dry-committed greatly reduces the time that it takes to obtain substantially homogeneous dispersion of the fibers throughout the fibrous composition. This, in turn, reduces the risk of mixture spoilage and mechanical or chemical damage to the solid components within the fibrous composition.

An antenna system that is insensitive to the surface on which it is mounted for use with a RFID tag having a wireless communication device, including a plurality of conductive tabs coupled to the wireless communication device for receiving and radiating radio frequency energy. At least two of the tabs are substantially identical in shape and coupled to the wireless communication device at feedpoint differing in location on each of the two tabs wherein the width of said at least two of said plurality of tabs taken transverse to the longitudinal centerline axis of each tab varies with distance along the longitudinal centerline axis of each of said tabs from its feedpoint. Alternatively, the wireless communication device is coupled to the tab at a feedpoint selected at a location differing on each of the tabs where the conducting area per unit length of the longitudinal centerline axis of each tab varies with distance along the longitudinal centerline axis of each of said tabs from its feedpoint. A radio frequency reflecting structure is coupled to the conductive tabs for reflecting radio frequency energy radiated therefrom. A dielectric material is located intermediate the conductive tabs and the radio frequency reflecting means.

The invention provides proteins from Neisseria meningitidis (strains A & B), including amino acid sequences, the corresponding nucleotide sequences, expression data, and serological data. The proteins are useful antigens for vaccines, immunogenic compositions, and/or diagnostics.

A plasma processing apparatus comprising: a process chamber for defining a plasma processing space in which a substrate holder for mounting a substrate thereon is installed; a plasma chamber in communication with an upper portion of the process chamber to generate and inject plasma into the plasma processing space such that the substrate is processed; a screen interposed between the process chamber and the plasma chamber to block plasma ions from being injected from the plasma chamber; and an ion trap for protecting the surface of the substrate from damage due to the injected plasma ion.

A method of performing radiation therapy includes delivering a therapeutic dose such as X-ray only to a target (e.g., tumor) with continuous broad beam (or in-effect continuous) using arrays of parallel planes of radiation (microbeams/microplanar beams). Microbeams spare normal tissues, and when interlaced at a tumor, form a broad-beam for tumor ablation. Bidirectional interlaced microbeam radiation therapy (BIMRT) uses two orthogonal arrays with inter-beam spacing equal to beam thickness. Multidirectional interlaced MRT (MIMRT) includes irradiations of arrays from several angles, which interleave at the target. Contrast agents, such as tungsten and gold, are administered to preferentially increase the target dose relative to the dose in normal tissue. Lighter elements, such as iodine and gadolinium, are used as scattering agents in conjunction with non-interleaving geometries of array(s) (e.g., unidirectional or cross-fired (intersecting) to generate a broad beam effect only within the target by preferentially increasing the valley dose within the tumor.

High-molecular compounds comprising repeating units represented by the general formula (1) or (2) and having number-average molecular weights of 10³ to 10⁸ in terms of polystyrene: (1) [wherein Ar¹ and Ar² are each independently a trivalent aromatic hydrocarbon group or a trivalent heterocyclic group; and X¹ and X² are each independently O, S, C(═O), S(═O), SO₂, C(R¹)(R²), Si(R³)(R⁴), N(R⁵), B(R⁶), P(R⁷), or P(═O)(R⁸), with the provisos that X¹ and X² must not be the same and that X¹ and Ar² are bonded respectively to the adjacent carbon atoms constituting the aromatic ring of Ar¹, and X² and Ar¹ are bonded respectively to the adjacent carbon atoms constituting the aromatic ring of Ar²] (2) [wherein Ar³ and Ar⁴ are each independently a trivalent aromatic hydrocarbon group or a trivalent heterocyclic group; and X³ and X⁴ are each independently N, B, P, C(R⁹), or Si(R¹⁰), with the provisos that X³ and X⁴ must not be the same and that X³ and Ar⁴ are bonded respectively to the adjacent carbon atoms constituting the aromatic ring of Ar³, and X⁴ and Ar³ are bonded respectively to the adjacent carbon atoms constituting the aromatic ring of Ar⁴].

A spoolable composite tube capable of being spooled onto a reel for storage and for use in oil field applications. The spoolable tube exhibits unique anistropic characteristics that provide improved burst and collapse pressures, increased tensile strength, compression strength, and load carrying capacity, while still remaining sufficiently bendable to be spooled onto a reel in an open bore configuration. The spoolable composite tube can include an inner liner, an interface layer, fiber composite layers, a pressure barrier layer, and an outer protective layer. The fiber composite layers can have a unique triaxial braid structure.

An instantaneous current and instantaneous voltage of a three-phase coil of a brushless DC motor are detected, and the internal condition of a compressor is predicted from these detection values. The prediction about the internal condition of the compressor is made in such a way that motor driving torque which is a parameter of a motor model is identified and poor lubrication, liquid compression or the like is predicted from this identified motor driving torque. This enables it to make, in real time, a failure forecast, failure diagnosis etc. on the compressor.
