A stent (10) for reinforcing a vessel wall is constructed from a single elongated wire. The wire is first bent into a series of tight bends. The wire is then further bent into a sequence of loops (50) that are connected by half hitch junctions (56) and interconnections which are either aligned or spiral around a circumference of the stent. The completed stent forms a cylindrical form which can be expanded from an initial diameter to a larger implanted diameter by application of a radially outward force from a balloon catheter (12) or the like.

Endovascular stent apparatus and method

A stent for reinforcement of the lumen of a peristaltic organ is formed by knitting preferably a nitinol wire into a pattern of overlapping loops selected such that from a relaxed state each row of loops may shift axially relative to and independently of the rows on either side. This local lengthening and shortening accommodate peristalsis of the organ without migrating within the organ. A stent is also shown which comprises two resilient cylindrical mesh layers and a semi-permeable compliant membrane such as expanded polytetrafluoroethylene, sandwiched between. The two mesh layers may be knit of a flexible filament, and the knit may be configured so that the stent can adapt to peristalsis of the body lumen. A method is also shown of manufacturing a delivery system for a resilient tubular device such as a stent so that the device can be inserted into the body in a substantially reduced diameter. The method uses a confining block having a bore and a slot leading into the bore. The tubular device is pinched and inserted into the bore and the slot, two mandrels are inserted into the bore, one inside the device and one outside and the mandrels are revolved about each other to roll the device on itself.

A method is disclosed to detect the presence of an analyte. The method involves forming a complex comprising the analyte and a binding entity. The binding entity comprises a first partner of an energy transfer system. The complex is then contacted with a reporting entity to form a unit. The reporting entity comprises a second partner of the energy transfer system. The first partner and the second partner are within Furster's radius of each other in the formed unit. The unit is irradiated with energy which can only be absorbed by one of said partners, namely, the energy donor, which then emits fluorescent energy. Some of this energy is absorbed by the other of said partners, namely, the energy acceptor, which also emits fluorescent energy. However, the fluorescent energy of the energy acceptor is of longer wavelength and in addition may be of substantially greater duration than the fluorescent energy of the energy donor. The detection of fluorescence at the longer wavelength or after a given time interval verifies the presence of the analyte.

Analyte detection by means of energy transfer

A soil cultivating implement of relatively large working width comprises a row of rotary soil working members that, in the working position of the implement, extends substantially horizontally perpendicular to the intended direction of operative travel A thereof, said soil working members being carried in two separate groups by corresponding substantially axially aligned hollow frame portions 23 with each soil working member rotatable about the upwardly extending axis of a corresponding shaft 25A. In order to enable the implement to tow a separate implement, machine or device that is to be used in combination therewith, it is provided with rear coupling means that includes rearwardly directed arms 46. The arms 46 and other parts of the rear coupling means are prevented from becoming bent, broken or otherwise damaged during use, and particularly during inoperative transport at which time the two frame portions 23 are folded upwardly and inwardly towards one another about pivots 4 by hydraulic rams 9, by providing a single frame beam 1 that is in advance of the rotary soil working members, mounting a coupling member or trestle 11 on a central portion 2 of that beam 1 and releasably bolting a carrying structure of the rear coupling means to the coupling member or trestle in a relatively fixed position. Preferably, chains or other flexible but inextensible tie members 51, 52 and 53 link the arms 46 to the carrying structure, link the arms to one another, and link the arms to the outer ends of upwardly tiltable outer portions 7 of the single frame beam 1.

A microwave heating device which comprises a heating chamber (3) to receive an article (2) being heated, a microwave generator (11) for irradiating microwaves in the heating chamber (3), and a steam generator (12) for supplying the heating chamber (3) with steam. Provided in the heating chamber (3) are heat accumulating plates (28a, 28b) adapted to be subjected to microwave irradiation for heating and heat accumulation. Accordingly, dewing resulting from steam is reduced in the heating chamber (3).

Concrete blocks consist of (per m3) : Sand (grain size 0-4 mm) 400-700 (530) kg. Slag (grain size 0-4 mm) 400-700 (550) kg. Gravel (grain size 3-9 mm) 500-700 (650)kg. Cement 200-400 (300) kg. Water 60-170 (80) kg. Blocks made from the concrete mix are fed to a tumbling machine in which the corners and edges are rounded off. The blocks after treatment are used to pave roads etc. The uniformity of the blocks give a smoother road surface with reduced traffic moise. Paving blocks made from the material have an antique appearance and provide better grip for tyres in bad weather. They are also cheaper than blocks made from blue basalt.
