Definitions

  • This invention covers an insulating and protective serving of wires and cables.
  • this invention specifically refers to permanent probes (pace-makers) acting on the cardiac muscle or used for any other neurologic application.
  • these single pole probes are consisting of multiple spiral connections (usually four wires) so as to ensure excellent resistance and flexibility. If differentiated loads are applied to the cardiac muscle or any other muscle, the required multiple pole connections have to be insulated both reciprocally and externally, which is currently achieved by silicone sheaths.
  • music steel strings of hand played instruments such as the strings of guitars, mandolins, harps etc. as well as of violins, 'cellos, etc.
  • surface corrosion mainly caused by acid perspiration which greatly damages their life and sound quality.
  • the wrapped wire is then stoved at a temperature which depends on the wire gauge. Stoving causes softening of the coating and thus improves the bond between turns as well as between wire and sheathing resulting in compaction and waterproofing of the finished wire surface.
  • the strings are usually in music wire and the protective serving may be the same as used for cardiac probes, i.e. in MYLAR or TEFLON.
  • the strings are no longer etched or exposed to corrosion caused by sweating hands, they will last much longer and maintain their original sound, which is a further objective of this intention.
  • Oven treatment will be the same as for the serving adopted for cardiac probes, except for the fact that the material having the above described characteristics, has a melting temperature of about 270°C.
  • 1 refers to the wire or cable covered by a first layer 2 consisting of a strap tightly spiral-wrapped in one (e.g. anti-clockwise) direction, topped by another layer 3 consisting of a strap tightly spiral-wrapped in the opposite (clockwise) direction.
  • these two layers may be covered by a third layer, spiral-wrapped in the same direction as the first one; the third layer may then be topped by a fourth, the spiral wrap of which will have the same direction as the second, and so on.
  • the straps used for the wrappings 2, 3 and following layers are usually in the same material and of the same size.
  • the conductor gauge When used for permanent probes, the conductor gauge is ranging between 0.10 and 0.14 mm and the strap thickness is about 14 micron. If two layers are applied, the final insulated and sheathed wire will have a diameter of ⁇ 0.16 - 0.20 mm.
  • the width of the strap will depend on the original diameter of the section which is reduced to 14 micron by drawing; for indicatory purposes, this width may be approx. 1 mm.
  • the strap may be in merchant type MYLAR or TEFLON which are both biocompatible and have excellent anticorrosion and insulating properties, although any other appropriate material may also be used for this purpose.
  • the wire or cable is placed in an oven for compaction of the wraps by bonding the layers both reciprocally and to the wire or cable.
  • Compaction is achieved by softening of the strap material which will require a temperature ranging between 90° and 180°C (the melting point of MYLAR and TEFLON being about 270°C) and a holding time of 4 - 5 hours, depending on the wire gauge and on the number or wraps.
