Definitions

  • the second device 6 is arranged in, or fixed to, the first outer tube or tube 1 in a similar manner (by means of a type coupling bayonet) to how the device 3 had previously been fixed with the first tube 1.
  • the coupling between the tube 1 and the device 6 is made by means of the second bushing 62 (instead of the third piece 35, as in the first device 1).
  • the surgeon activates the second inner tube or tube 2 until the bushing 61, in turn, pushes the rods 63 until they are inserted into the wall of the urethra 4.
  • the activation is illustrated in Figures 6A to 6D and works in a manner similar to that of the activation of the rods 33 in the fixed device 3 with the bladder 5.
  • a pump located at the proximal end of the tube 2 is pressed, a fluid is injected along the tube 2 (along the conduit 28) and, when this fluid reaches the distal end of the tube 2, the grooved part 25 of the tube 2 is filled with this fluid at a certain pressure.
  • the pressure is applied by injecting serum at a pressure that varies within the range of 0.2 to 1 bar and, more preferably, 0.5 to 1 bar.
  • the manipulator pulls the inner tube 2 proximally, in such a way that the first bushing 31 of the first device 3 moves backwards. This causes the rods 33, which until then were curved, to slide along the channels and become straight (their original natural position). This is shown in Figure 6M.
  • the outer tube 1 is held and fixed substantially with the other hand.
  • the tube 82B does not have a grooved part that expands or inflates as a result of the pressure exerted by the fluid.
  • the tube 82B has two orifices or conduits to the channels or guides 66: an orifice 801 to the rear of each channel or guide (the part through which each rod begins to access) and an orifice 802 input to a part of the front half of each channel or guide (the part that approximately begins to bend each rod once it has traveled at least half of the corresponding channel or guide).

Abstract

L'invention concerne un système pour relier directement une vessie (5) à un urètre (4), comprenant : un premier dispositif (3) pourvu de tiges (33); un second dispositif (6) pourvu de tiges (63); un premier tube (1) conçu pour les dispositifs en vue de leur introduction dans l'urètre (4) jusqu'à ce qu'ils atteigne la vessie ou la fin de l'urètre, respectivement; au moins un second tube (2; 82A, 82B) qui peut glisser le long du premier tube. Les tiges sont droites. Le système comprend des moyens d'activation destinés, en réponse à leur manipulation lors de l'utilisation du système, à injecter un liquide le long d'au moins un second tube, appliquant une pression qui provoque le déplacement d'une partie mobile (31, 61) des dispositifs (3, 6), forçant les tiges à se déplacer le long de canaux (36, 66) jusqu'à ce qu'elles s'accrochent à la paroi interne de la vessie ou de l'urètre, accrochant respectivement le premier dispositif (3) avec la vessie (5) ou le second avec l'urètre. Pendant l'utilisation du système, et lorsqu'ils s'accrochent respectivement à la vessie (5) et à l'urètre (4), les deux dispositifs se fixent l'un à l'autre, reliant ainsi la vessie à l'urètre. L'invention concerne également un procédé destiné à relier une vessie à un urètre.
