  • Antenatal risk assessment screening for pregnancy abnormalities
    Patent number: 6022695
    Abstract: Dimeric inhibin concentration can be used in the determination of the risk of a women carrying an unborn child affected by chromosomal abnormalities, e.g. Downs Syndrome. A method for antenatal screening for chromosomal abnormalities is carried out by measuring body fluid taken from a pregnant woman for the level of at least one marker or precursor or metabolite of the marker together with the gestational age of the woman are compared with reference values taken from women carrying fetuses with chromosomal abnormalities and/or women carrying normal fetuses, using dimeric inhibin as a marker. A second marker is the free beta subunit of human chorion gonadotropin. An apparatus for carrying out the method described comprises a computer with a means for comparing the values described.

  • Precision powder injection molded implant with preferentially leached texture surface and method of manufacture
    Patent number: 6022509
    Abstract: An implant component adapted for bone attachment or replacement is molded from a feed stock which contains a soluble major binder, a backbone binder and structural powder material. After the feed stock is injection molded to form a compact or preform, the major binder is removed from the green article, leaving a structure of interconnected porosity or texture, while the backbone binder remains until the component is sintered. Preferably, the amount of the soluble binder is set to increase the porosity, or reduce the stiffness, of the finished component, thus introducing a biocompatible or growth-enhancing level of porosity or stiffness during the molding process. In further or alternative embodiments, the component may be injection molded onto or about a solvent-leachable spacer preform and/or adjacent to another injected or molded portion of the component which serves as a structural body, frame or shell.

  • Swellable wound dressing materials
    Patent number: 6022556
    Abstract: The invention provides water swellable wound dressing materials comprising from 5% to 50% of an alginate ester of a C.sub.1 -C.sub.6 polyhydric alcohol; from 50% to 95% of a humectant consisting of one or more C.sub.1 -C.sub.6 monohydric or polyhydric alcohols; and from 0% to 30% of water, the percentages being calculated by weight based on the weight of the material when anhydrous. The preferred alginate ester is propylene glycol alginate (PGA). The materials swell but do not dissolve in cold or warm water. Insolubility is achieved by the addition of polyvaent cations such as calcium ions, or by covalent cross-linking of the pga, or by adding from 10 to 35% by weight of water-swellable polysaccharide such as gelatin, or by adding from 5% to 20% by weight of a cationic polymer such as chitosan.

  • Powder-free medical gloves
    Patent number: 6019922
    Abstract: A powder free medical glove having an outer side a silicon treated surface and the inside of cross linked coagulated glove bonded with a layer formed of an anti-blocking composition. The anti-blocking composition includes of a polymer or copolymer mixed together with a micronised high density polyethylene material and wax in suitable blends that result in the composition having anti-blocking and improved lubricity properties. The medical glove with the skin contacting anti-blocking coating enables donning of the glove to be effected without the aid of donning powder such as starch powder. When the finished glove is washed and rinsed with water to remove the coagulant powder, and the said glove treated with a silicon solution, a glove substantially free of loose powder glove is produced and has good lubricity for donning.
