摘要:
This invention is an improved method and device for treating varicose veins 200 or the greater saphenous vein 202. The method comprises the use of infrared laser radiation in the region of 1.2 to 2.2 um in a manner from inside the vessel 200 or 202 such that the endothelial cells of the vessel wall 704 are damaged and collagen fibers in the vessel wall 704 are heated to the point where they permanently contract, the vessel 200 or 202 is occluded and ultimately resorbed. The device includes a laser 102 delivered via a fiber optic catheter 300 that may have frosted or diffusing fiber tips 308, or that may be provided with a protective spacer. A motorized pull back device 104 may be used, and a thermal sensor 600 may be used to help control the power required to maintain the proper treatment temperature.
摘要:
An electrode catheter is introduced into a hollow anatomical structure, such as a vein, and is positioned at a treatment site within the structure. Tumescent fluid is injected into the tissue surrounding the treatment site to produce tumescence of the surrounding tissue which then compresses the vein. The solution may include an anesthetic, and may further include a vasoconstrictive drug that shrinks blood vessels. The tumescent swelling in the surrounding tissue causes the hollow anatomical structure to become compressed, thereby exsanguinating the treatment site. Energy is applied by an electrode catheter in apposition with the vein wall to create a heating effect. The heating effect causes the hollow anatomical structure to become molded and durably assume the compressed dimensions caused by the tumescent technique. The electrode catheter can be moved within the structure so as to apply energy to a large section of the hollow anatomic structure. In a further aspect, the location of the electrodes is determined by impedance monitoring. Also, temperature sensors at the treatment site are averaged to determine the site temperature.

The invention relates to a method for printing printed material which is individualized with logistical printed image elements, wherein at least one printed image, particularly a static printed image, which is printed in a printing machine, is individualized by technically adding at least one dynamic logistical printed image element. According to the invention, data of the/each dynamic logistical printed image element is combined in such a way that the/each printed image and the/each logistical printed image element are automatically updated by comparing data between a data bank provided by a print job user and a data bank provided by a logistics provider prior to printing the printed material individualized with the/each logistical printed image element.

The invention relates to a method for producing an RFID label using a printing method. The aim of the invention is to apply the required parts to the label in a simple manner, and preferably also to protect the antenna from mechanical damage. To this end, at least part of the antenna required for the operation of the label and part of the oscillating circuit is applied to the stock by means of sheet-fed offset printing or directly or indirectly by means of a relief-printing plate. In order to protect the oscillating circuit from damage, the application surface thereof is lowered, or the oscillating circuit and the antenna are lowered into the stock after the application process.

The present invention relates to novel treatments of mammalian and human heart failure directed at improving cardiac creatine kinase metabolism, the prime energy reserve of cardiac muscle. The invention also relates to novel treatments using gene transfer vectors to increase myocardial creatine kinase protein expression and/or creatine kinase activity, as well as flux through the creatine kinase reaction and to thereby improve cardiac contractile function and ameliorate remodeling in heart failure. The invention further relates to methods for screening and identifying compounds that increase creatine kinase expression and/or creatine kinase activity as potential pharmaceutical compositions for heart failure therapy.

The present invention provides a system for achieving erythema and/or mild edema in an upper layer of skin, without causing blisters, and without the risk of high fluence levels or critical need for cooling.
摘要:
A device is disclosed for trapping mosquitoes. The device includes a housing, a bag and a fan located in the housing. The fan creates capture zone with an air flow towards the bag. A plurality of light sources attract mosquitoes to the capture zone. The light sources include an ultraviolet light, a plurality of light emitting diodes, and an incandescent light. A heat source also attracts the mosquitoes to the capture zone.
摘要:
A device for the simultaneous double-side grinding of workpiece wafers has two collinear grinding wheels and two hydropads oppositely positioned for hydrostatic bearing of the workpiece, each having at least one hydrostatic bearing and at least one dynamic pressure tube for measuring the spacing between the workpiece and the hydrdopads. The surfaces of the hydropads which face the workpiece are of nonplanar configuration, contoured in such a manner that the spacing between the surface and the workpiece adopts a minimum value near the edge of the hydropads proximate the grinding wheels, this spacing increasing at increasing distance from the grinding wheels. In a further embodiment, at least one bore, through which liquid and abraded material can be discharged from the vicinity of the dynamic pressure tube, is proximate each dynamic pressure tube.
