The present invention is directed to a cold cutting polypectomy snare. The cold cutting polypectomy snare has a cross section optimized for polypectomy. In some embodiments, the snare may have a uniform cross section along a length of the snare. In other embodiments, the snare may include a first side and a second side, wherein the first and second sides each have a unique cross section. Further, the cross-sections of the first side and the second side can be configured to couple together when a diameter of the snare is decreased to affect a cutting of a polyp.

A steel cord for the reinforcement of elastomer products such as elevator belts, conveyor belts, synchronous or timing belts or hoses or tyres is presented. The steel cord comprises strands and monofilaments made of steel filaments. The strands themselves are also made of steel filaments twisted together. The strands form the outer layer of the steel cord. The monofilaments are twisted into the cord with the same lay length and direction as the strands and are positioned in the valleys between the strands on the radial outer side of the steel cord. The steel cord has the advantage that it has a better fill factor and a rounder aspect. Furthermore the monofilaments may act as an early wear indicator of the elastomer product.

A steel cord that is suitable for reinforcing rubber articles such as tires. The inventive steel cord enables to completely eliminate the presence of cobalt in a tire when combined with the proper cobalt free compound. Advantageously the steel cord adheres equally well to rubbers containing organic cobalt salts. The inventive wire is different from prior art steel cords in that the brass coating now comprises iron particles. The iron particles have a size between 10 nm and 10 000 nm. The presence of iron mitigates the adhesion retention loss of the rubber to steel cord bond in a hot and humid environment. It is a further advantage that the inventive steel cord does not contain any intentionally added cobalt thereby contributing to the elimination of harmful substances in the production area as well as the environment.
