Medical instrument working end and method for endoluminal treatments

A medical instrument that utilizes electrical energy delivery between first and second opposing polarity electrodes in an interior bore of a working end to cause vaporization of an inflowing fluid media. The vaporization and expansion of the fluid media creates pressure gradients in the working end that causes heated vapor to propagate distally from the working end. The propagation or jetting of the vapor media is used to controllably cause thermal effects in endoluminal environments. The instrument and method can be used to shrink and occlude blood vessels in a treatment for varicose veins.

High speed, high density interconnect system for differential and single-ended transmission applications

The present invention is directed to a high density electrical connector which can provide 80 or more twinax connections per linear inch in a 20 millimeter card slot. In a typical electronic system package, 20 millimeters is the spacing from center line to center line of the adjacent parallel daughtercards. Twinax cable is coaxial cable that contains two inner conducting wires rather than one. The two inner conducting wires provide two physical channels. Coaxial cable is called “coaxial” because it includes one physical channel that carries the signal surrounded (after a layer of insulation) by another concentric physical channel, both running along the same axis. The outer channel serves as ground.

Safety penetrating method and apparatus into body cavities, organs, or potential spaces

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.

Methods for dispersing fibers within aqueous compositions

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.

Methods for implementing microbeam radiation therapy

InactiveUS20060176997A1Enhance in-beam absorptionEnhance therapeutic doseX-ray/gamma-ray/particle-irradiation therapyIrradiation devicesAbnormal tissue growthOrthogonal array
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.

Light-emitting diode lighting tube

A light-emitting diode (LED) lighting tube is of a disassembleable structure, which arranges those components that are susceptible to easy damage in an end cap that is located at an outer side. Thus, when the lighting device is malfunctioning, it only needs to replace the end cap module that is located at the outer side to resume normal operation of the lighting tube. Parts of long lifespan of the lighting tube are preserved so that the costs are reduced and the tread of environmental protection is met.

Methods for Implementing Microbeam Radiation Therapy

A method of performing microbeam radiation therapy (MRT) includes delivering a dose only to selected tissue in a target volume (10) with continuous broad beam, first, by interleaving arrays of microplanar beams (30,36) only at the target (10). Administered contrast agents can supplement the effect by preferentially increasing the target dose relative to dose in normal tissue. A broad beam effect is alternatively created using non-interleaving microbeam array(s) with scattering agents administered to selected tissue that preferentially increase valley dose (69) within target to approximate broad beam. The methods of interleaving microbeams are also applied to treat diseases and conditions by ablating at least a portion of selected tissue, or by damaging blood-brain barrier for efficient drug and / or cell administration. A system for performing interlaced microbeam radiosurgery preferably includes two orthogonal radiation source arms (102) for producing and interleaving microbeam arrays (30,36) at the target volume (10). The methods treat tumors, pain, epilepsy, and neurological diseases.

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.
