    摘要: An HIPR emulsion of bitumen in water is prepared by a method which comprises directly mixing 70 to 98% by volume of bitumen having a viscosity in the range 200 to 500,000 mPa.s at the mixing temperature with 30 to 2% by volume of an aqueous solution of an emulsifying surfactant, percentages being expressed as percentages by volume of the total mixture. Mixing is effected under low shear conditions in the range 10 to 1,000 reciprocal seconds in such manner that an emulsion is formed comprising highly distorted bitumen droplets having mean droplet diameters in the range 2 to 50 micron separated by thin films of water. The emulsions can be cut back to provide stable emulsions of lower bitumen content which are useful in roadmaking and the formation of protective coatings.

    摘要: An HIPR (high internal phase ratio) emulsion of oil in water is prepared by directly mixing 70 to 98% by volume of a viscous oil having a viscosity in the range 200 to 250,000 mPa.s at the mixing temperature with 30 to 2% by volume of an aqueous solution of an emulsifying surfactant or an alkali, percentages being expressed as percentages by volume of the total mixture. Mixing is effected under low shear conditions in the range 10 to 1,000 reciprocal seconds in such manner that an emulsion is formed comprising highly distorted oil droplets having mean droplet diameters in the range 2 to 50 micron separated by thin interfacial films. The emulsions are much less viscous than the oils from which they are prepared and may, optionally after dilution, be pumped through a pipeline.

    摘要: A braided stent (1) for transluminal implantation in body lumens is self-expanding and has a radial expanded configuration in which the angle α between filaments is acute. Some or all of filaments (6,7) are welded together in pairs at each end (4,5) of the stent to provide beads (8), thereby strengthening the stent and assisting its deployment from a delivery device. The stent is preferably completely coated using a biocompatible polymeric coating, said polymer preferably having pendant phosphoryl choline groups. A method of making the stent by braiding and welding is described as well as a delivery device for deploying the device. The present invention provides a biocompatible crosslinked coating and a crosslinkable coating polymer composition for forming such a coating. The biocompatible crosslinked coating may be formed by curing a polymer of 23 mole % (methacryloyloxy ethyl)-2-(trimethylammonium ethyl) phosphate inner salt, 47 mole % lauryl methacrylate, 5 mole % γtrimethoxysilyl propyl methacrylate and 25 mole % of hydroxy propyl methacrylate. The crosslinkable coating polymer may include 23 mole % (methacryloyloxy ethyl)-2-(trimethylammonium ethyl) phosphate inner salt, 47 mole % lauryl methacrylate, 5 mole % γtrimethoxysilyl propyl methacrylate and 25 mole % of hydroxy propyl methacrylate.

    摘要: The present invention relate to a balloon expandable stent mounted on a balloon catheter, the entire assembly being overcoated with a coherent polymer coating, which is preferably substantially continuous over the circumference and, more preferably, axial length of the stent on the balloon. The polymer coating improves retention of the stent on the balloon during delivery and does not adversely effect the deployment characteristics, nor the balloon failure characteristics. The product is made by mounting the stent on the balloon and coating the assembly with a liquid coating composition containing a suitable polymer followed by curing of the coating. The polymer is biocompatible and preferably crosslinkable in the coating composition, and crosslinked in the final product. A suitable polymer is formed from monomers including a zwitterionic, preferably a phosphoryl choline, group, and monomers including a trialkoxysilyl group. Preferably the coated product is contacted with ethylene oxide to provide simultaneous sterilization and additional curing.

    摘要: An implant having a coating comprising a polymer matrix is swollen in a pharmaceutical solution whereby pharmaceutically active compound is imbibed into the polymer matrix. When the product is implanted, release of the pharmaceutically active compound from the coating takes place. The polymer is preferably formed from ethylenically unsaturated monomers including a zwitterionic monomer, most preferably 2-methacryloyloxyethyl-2′-trimethylammoniumethyl-phosphate inner salt. The monomers from which the polymer is formed may further include surface binding monomers, such as hydrophobic group containing monomers, and crosslinkable monomers, the content of which may be used to control the swellability. Preferably the implant is a stent and the coating of polymer on the exterior wall surface is thicker than the coating of polymer on the interior surface. Release of the drug may be controlled by selection of comonomers. The implant is suitably a stent for use in the cardiovascular system.
