Definitions

  • the present invention relates to the field of angioplasty.
  • It relates more particularly to a device intended to introduce a material, for example a stent, into the arterial network by endoscopic route.
  • the invention aims to solve the problem of positioning a material such as a beveled stent at a bifurcation.
  • the beveled stent has a bias which must be positioned angularly so as to optimize blood circulation.
  • patent PCT / US97 / 18201 describes a beveled stent and equipment consisting of a balloon guided by a guide wire, A stabilization catheter guided by a second guide wire is intended to prepare the positioning of a bifurcation.
  • Another patent published under the number EP891751, discloses a balloon comprising a coil which is positioned in the main artery, "to facilitate the positioning of a balloon in a lateral channel.
  • the invention relates to a device for positioning a material introduced into the arterial network by endoscopy, characterized in that it consists of a tubular element having a asymmetrical lateral extension for the angular positioning of the material.
  • This asymmetrical extension allows angular positioning of the device relative to the orientation of the bifurcation.
  • the tubular element consists of an inflatable balloon.
  • the tubular element is formed by an inflatable balloon extended by a lateral protuberance.
  • the tubular element is extended by a lateral lug for the angular positioning of the material.
  • the lateral extension has a radio-contrasted mark.
  • the device comprises a retaining means for maintaining the lateral extension in the folded position against the tubular element during the introduction phase.
  • the retaining means consists of a link capable of being released by traction on a wire.
  • the positioning device comprises a removable sleeve surrounding, at the time of introduction into the artery, the stent and the lateral protrusion, said sleeve being able to be removed near the bifurcation to release the lug lateral.
  • the removable sleeve includes an asymmetric radiopaque marker.
  • FIG. 1 shows a device during the introduction phase
  • FIG. 2 represents a device during the positioning phase
  • - Figure 3 shows a sectional view of an alternative embodiment
  • Figures 4 and 5 show views of alternative embodiments, after removal of the removable sleeve
  • the device consists of a balloon
  • This balloon (1) substantially cylindrical.
  • This balloon (1) is advantageously inflatable to provide an accessory function of expanding a stent.
  • the lug (2) is folded back in the axial position. It can be held by a sheath (4) which holds the lug
  • This sheath (4) is attached to a wire (5) making it possible to withdraw it in the proximal direction to release the lug (2), as shown in FIG. 2.
  • the lug then comes to orient itself in a radial direction. It constitutes an angular reference allowing the positioning of the device and of the material which it supports, for example a beveled stent.
  • the lug (2) has a radio-contrast mark to check the orientation and correctly position the beveled stent.
  • It can also be produced in the form of a main balloon of tubular shape, extended by a separately inflatable lateral protuberance. It can also be produced in the form of a tubular element extended at the distal end by a silicone lug or by an inflatable lug.
  • the lug can be proximal or distal with respect to the balloon or other systems carrying the stent, if the latter is self-expanding with shape memory.
  • Figure 3 shows a sectional view of an alternative embodiment with a removable sleeve (10), in the insertion position
  • Figures 4 and 5 show views of alternative embodiments, after removal of the removable sleeve.
  • the catheter (11) forms a support for the beveled stent (12).
  • This catheter (11) has for this purpose a distal part (13) whose cross section corresponds to the internal cross section of the endoprosthesis (11) in the retracted position.
  • a shoulder (14) blocks the stent (11).
  • the sleeve (10) can be removed by pulling on a wire fixed to the end of said sleeve.
  • the withdrawal of the sleeve (10) releases the lateral lug (15 or 16), which can be in the distal position, in front of the stent (10), as shown in FIG. 4, or in the proximal position, behind the stent (10 ), as shown in Figure 5.
  • Figures 6 to 9 show other alternative embodiments, with a metal guide (20) passing through the carrying catheter (11) and emerging in the proximal region by a lumen (21) which can be located behind the stent (10) as shown in Figures 6 and 7, or in front of the stent (10) as shown in Figures 8 and 9.
  • the lumen (20) is provided in the oblique area (17) of the stent (10) intended for connection with the daughter branch .
  • the guide (20) is introduced into the daughter branch of the arterial bifurcation. It can be directed in the antegrade direction or in the retrograde direction depending on the configuration of the channel and its opening in the catheter (11).
  • the markers, pins or guide are held against the carrying catheter (11) by means of the external sleeve (12) during the stage of introduction into the artery.
  • the withdrawal of the retractable sleeve (12) causes the erection of the lug, and allows the advancement of the guide (20).
  • the withdrawal of the sleeve can be carried out on the proximal or distal side.
