  • the function of the outer section is to hinder the catheter (drain) to slip in.
  • the outer section is shorter, than the middle section.
  • the urological catheters in most cases are used for smoothing over urethra-strictures.
  • a typical example is the prostate enlarging: the prostate and the part of the urethra (running in it) , the so called pars prostatica make only small part of the complete length of the urethra (about 20cm). This length in zero-setting 2,5-4cm, but in case of prostate enlarging it is rarely bigger than 5-7 cm.
  • the export shape makes it possible to adjust the length of the urological catheters to the useful part of the bridging.

  • the elastic inner pigtail eludes the intestines which contingently may drift towards it.
  • the invention's twelve sections are provided with constant wall, which means that there are no gaps or breakthrough on the sidewalls. These twelve sections serve the lead of the body liquid from the ventricle, or the bridging of the stricture.
  • the spiral-diameter of the middle 12 sections pigtail's shape is advantageously smaller, than the shape of the spiral-diameter in the inner 10 sections.
  • outer 14 sections advantageously also pigtail formed - outer 14 sections contain 17 exitgaps, where the bodyliquid can be led across.
  • the outer 14 sections are provided with 15 sidegaps, where the urine exits, or other liquid in case of a drain.
  • the outer 14 sections are expediently shorter than the middle 12 sections.
  • the outer 14 sections Due to the flexible past of the pigtail shaped outer 14 sections, after the removal of the leadingwire or the propstring it hooks, so helping the positioning of the equipment. Similarly to the middle pigtail, it is capable for non-stop adaptation, respectively lowers the danger of decubitus due to its mobility.
  • This section's pigtail shape means additional safety against sideeffects in cases where the equipment slips into the body in extreme measure.
  • the outer 14 sections may not only be pigtail shaped but it can be provided by other arbitrary for example straight shapes.

  • the 16 closingdevice advantageously is located at the meeting point of the middle 12 sections and the outer 14 sections and the in the territory of the 16 closingdevices the equipment is formed with a larger cross-section in order to hinder it to slip in to the ventricle.
  • the part wider than the other parts of the equipment helps the positioning, because it indicates the start of the narrowed part during inserting. Concering its shape it is advantageously assymmetrical arbor shaped, where the inner end is wider than the outer, and it connects with appropiate transition to the outer and middle 14,12 sections.
  • the 16 closingdevices may exemplary contain 32 closingunits prostrained with 30 springs, and 20 leading strings that are fixed to 32 closingunits and are outlet of the body. It opens the 16 closingdevices by pulling.22 "ears" are fastened to the end of the 20 exit strings which facilitate the opening of the 16 closingdevices. The 22 ears hinder the string to slip in, on the other hand it helps to identify the otherwise thin string during use.
  • the 16 closingdevices can be of course formed as electromagnetic or other type of lock.
  • the 20 exit strings lead outside of the opening of the urinary canal or across other bodysurface gap.
  • the 20 exit strings secure the opening of the lock by a slight pull, on the other hand the equipment can be taken away by the increase of pulling force.
  • This exit string can contain a so called optic or electronic wiring, whichby we can gain information about the characteristics (e.g. pH,ion content, temp, etc.) of inner liquid collected in the abdomen or other ventricle.
  • the measure string must be so long that it enters the ventricle determined by the pigtail.
  • Equipments appropiate to the required measurements can be connected to its outer end.
  • the 20 exit strings are thin, the sideffects observed on the conventional catheters can be eliminated.
  • the 20 exit strings are made of thin, large and tensile strength strings. It is barley sensible due to its size, it does not irritate and does not cause ascending infection.
  • the equipment is seen in position for the void of 40 bladder. It is seen on the figure that the pigtail shaped inner 10 sections are located in the 40 bladder, the also pigtail shaped middle 12 sections bridge the extension of the 42 prostates, the exemplary also pigtail shaped outer 14 sections are located on the 44 ureters' initial segment.
  • the equipment described previously can be placed in with the help of the 18 propstrings or -wires. After the removal of the propstring the triple pigtail hooks and takes position. Dependency from the modification of the bodyposition, the catheter's (drain) position automatically corrigates.
  • the equipment can be produced with solid length because the double or triple pigtail combination secures appropiate length adaptation, in most cases.
  • the equipment's width is chosen by the following.
  • the inner pigtail is the thinnest part, for the easy insert, with 10-12 Ch diameter
  • the middle pigtail has similar width, 10 -12 Ch diameter suits here as well.This part is expediently somewhat shorter, 5-7 cm.
  • the closingdevice's territory is wider, than the catheter's other parts, its diameter is 16-18 Ch. Its length is advantageously 1 - 1,5 cm,dependently from the closingdevice.
  • the outer 14 sections' width is advantageously 14 Ch, its length 2-3 cm. In the case of drains the diameter might be smaller, and the size of trocar used for insert suits it. In case of drains 1,5 -2 cm width is satisfactory.
  • the invention's important advantage is that it is provided with the appropiate length in the case of urological catheters. This way a larger part of the urethra devoids the constant sideffects caused by the catheter, for example mechanical irritation,injuries, infections, secondary narrowings.
  • the inner pigtail does not irritate the bladder-wall, (the ventricle's wall in case of drain), not even when the chamber is absolutely empty.
  • the double or triple pigtail construction makes the complex dinamic adaptation possible. On one hand it positions the equipment (catheter,drain) into the narrow territory.On the other hand this positioning is in change according to the modification of bodyposition, the incidental infenction's decrease or the to the change of the bladder's size (the different ventricles in case of drains).
  • the equipment's width (10-14 Ch) is smaller than that of the conventional catheters' (16-20 Ch), on the other hand the double or triple pigtail structure reduces the pressure on every part of the catheter.
  • the insert of the equipment is extremely easy, because it is relatively thin, its inner end is rounded, its material is elastic, and the closingdevice-part indicates the place of narrowing.
  • the closingdevice is simple, and the liquid's removal is easily carried into effect.
  • the equipment does not block sexual life in case of constant insert.
  • the equipment can be applied for women as special catheter with a little modification: the outer section's length and width must be cut back, respectively the leading string may be shorter. This way the female catheter can be applied in case of incontinence.
