Abstract: A dehydrated hydrogel incorporating a plasticiser and fibers which have provided cations for cross-linking the dehydrated hydrogel.

Abstract: Fibres which are useful in wound dressings comprising an alginate co-spun with at least one water soluble organic polymeric species (other than an alginate). Examples of such fibers comprise alginate and CMC.

Abstract: A wound dressing beneficial for use on high exuding wounds comprising a breathable film having an increased MTRV capability and an absorbent layer having high fluid holding capacity located on the film side remote from the wound. The dressing is further characterized by a low profile suitable for use under garments. The dressing may further comprise a third layer located on the film side proximal to the wound that is alternatively either absorbent to further control moisture levels at the wound site, or alternatively promotes the production of exudate to facilitate the flushing of the wound. The dressing may also comprise a compressive element on the side of the absorbent layer remote from the wound to provide compressive therapy capability.

Abstract: Melt extrudable thermoplastic polytetramethylene ether polyurethane-urea elastomers of this invention are prepared by reacting a tetramethylene ether glycol with 4,4'-diphenyl methane diisocyanate to form a polytetramethylene ether polyurethane pre-polymer having a number average molecular weight of from about 2,000 to about 10,000. This pre-polymer is water extended to form a thermoplastic bio-compatible elastomer having a number average molecular weight of about 50,000 to about 100,000, and a weight average molecular weight of about 300,000 to about 1,000,000. The elastomer so obtained has a softening point in the range of 127.degree. - 149.degree. C. and may be melt extruded without decomposition to produce articles useful in the field of medicine and surgery.

Abstract: A bonding wedge for joining or bonding wire leads to contact areas or elements in the semiconductor and electronic industry including a rectangular wire guiding hole extending therethrough cooperating with a positioning groove formed on the bonding tip.
