Description

  • The invention relates to a valve introducer fitted with an adaptor for introduction into a human or animal body.
  • It will be of particular use in vascular surgery.
  • The instruments introduced into a human or animal body require the presence of shutter components to ensure that the introducer is leakproof.
  • This is particular true during endovascular surgery with the introduction of surgical instruments in an introducer since there must not be any backflow of blood through the introducer.
  • Valves for surgical instruments deformable by twisting already exist to increase the leakproof qualities of the instrument.
  • This solution is not fully satisfactory because when introducing several surgical instruments such as catheters and guides, there remains a gap between the instruments despite the valve, causing a leakage of blood.
  • Document WO00/32263 has already described an introducer device for use in the human body comprising a main elongated body fitted, at the proximal end, with several openings for surgical instruments. The device has leakage problems because the main elongated body is introduced directly into the human body and the instruments pass through it.
  • Moreover, the system is not very easy to use because, once the device has been introduced, there cannot be any change in diameter or in the number of openings in the proximal extremity without withdrawing the device, thereby leading to leakage of fluid from the human body.
  • There is therefore a need for a device that allows for the simultaneous use of several surgical instruments or instruments of very different sizes via an introducer in the human or animal body that produces a good seal and is easy to use.
  • To this end, the invention proposes a valve introducer for the human or animal body, characterised in that it comprises an adaptor whose outer surface is adapted to cooperate with the valve, an interior volume with at least one duct for allowing surgical or medical instruments having an elongated body to pass through and leakproof means.
  • According to one embodiment, the ducts of the adaptor comprise leakproof means at their proximal end and/or at their distal end.
  • Advantageously, the adaptor consists of an elongated, cylindrical body able to cooperate with a valve deformable by twisting.
  • The leakproof means in the ducts and the elongated body ensure that the adaptor and the adaptor-introducer are well-sealed.
  • Advantageously, the leakproof means at the distal extremity are also designed to avoid excessive movement of catheters by maintaining them in position along a certain axis.
  • The leakproof means at the distal end also plays a centring role.
  • Advantageously, the adaptor is characterised by an outer surface able to cooperate with the introducer and the means of attachment to the introducer.
  • Advantageously, the adaptor is characterised by a conical distal extremity designed to improve the insertion of the adaptor in the introducer by cooperating with a flat centring valve in the introducer and/or by causing the leakproof valve in the introducer to open, especially if the introducer is fitted with a leakproof valve deformable by twisting.
  • According to one embodiment, the adaptor ducts consist of a section that is more or less longitudinal compared to the body of the adaptor. They also have a divergent proximal section. This makes it easier to manipulate the surgical instruments introduced in the adaptor.
  • Advantageously, the centres of the proximal openings in the ducts lie in a predetermined circle.
  • According to one embodiment, a channel is located in the centre of the circle predetermined by the proximal openings of the ducts and, advantageously, this channel has the same leakproof means as the ducts.
  • Advantageously, the said channel is rectilinear to facilitate the handling of surgical instruments and especially the passage of a guide wire.
  • Other aims and advantages will become apparent during the following description of a preferred embodiment of the invention. However, this embodiment is not limitative.
  • It is appropriate to remember that the invention relates to a valve introducer for the human or animal body, characterised in that the valve is deformable by twisting and able to cooperate with an adaptor via its outer surface; the inner volume of the said adaptor comprises at least one duct allowing the passage of surgical or medical instruments with an elongated body; and the duct comprises leakproof means.
  • According to the preferred variations of the invention, the introducer is such that:
      • the duct in the adaptor comprises leakproof means at its proximal end,
      • the leakproof means at the proximal end of the adaptor duct include a haemostatic valve,
      • the duct in the adaptor comprises leakproof means at its distal end,
      • the leakproof means at the distal end of the adaptor duct include a haemostatic valve,
      • the haemostatic valve is held in place between a support and a washer,
      • the centres of the proximal openings of the adaptor ducts are located in a predetermined circle,
      • a channel is located in the centre of the circle predetermined by the proximal openings of the adaptor ducts and the said channel is rectilinear,
      • the adaptor ducts consist of a section that is roughly longitudinal compared to the elongated body of the adaptor and a divergent proximal section,
      • the adaptor ducts have different diameters,
      • the adaptor includes a conical distal extremity,
      • the adaptor comprises means of attachment to the introducer,
      • the adaptor includes a cylindrical elongated body,
  • According to the preferred variations of the invention, the introducer is such that:
      • it is fitted with a valve deformable by twisting which cooperates with an adaptor via its outer surface as previously described,
      • it has a flat centring valve able to cooperate with the distal end of the adaptor to facilitate its insertion by centring it.
  • The enclosed drawings are given as examples and do limit the scope of the invention. They represent only one embodiment of the invention and will make it easily understandable.

  • Adaptor (1) for valve (15) of the introducer (16) in the human or animal body comprises an outer surface (2) able to cooperate with valve (15).
  • Adaptor (1) comprises an elongated body (17) advantageously cylindrical in shape able to cooperate with valve (15) of introducer (16).
  • Advantageously, a sort of skirt (18) partially covers the elongated body (17) of adaptor (1).
  • According to one embodiment, valve (15) of introducer (16) is a valve deformable by twisting.
  • Valve (15) is comprised of a soft portion that is more or less cylindrical in shape consisting of a hollow section of flexible leakproof material such as silicone.
  • Both extremities (19) and (20) of valve (15) are joined to other parts used in the twisting of valve (15).
  • If there is no stress on the flexible portion, its centre is completely open allowing for the passage of surgical or medical instruments through valve (15).
  • Using cursor (21), the operator rotates extremity (20) by means of a cable. Twisting of the flexible section then tends to create an area of narrowing approximately in the middle of the flexible portion lengthways.
  • When an object is to be introduced through valve (15), the operator activates cursor (21).
  • It is also possible to rotate extremity (19) instead of extremity (20) and to simultaneously rotate the two extremities (19) and (20) in opposite directions.
  • According to one embodiment, the introducer may comprise an initial flat centring valve further up from valve (15) deformable by twisting.
  • Advantageously, the flat centring valve is of the tricuspid or punctiform type.
  • Adaptor (1) contains in its interior volume (3) at least one duct (4) allowing for the passage of surgical or medical instruments with elongated bodies.
  • According to one embodiment, adaptor (1) includes three ducts (4).
  • Advantageously, the ducts (4) comprise leakproof means at their proximal end (6) and/or distal end (5).
  • According to one embodiment, the ducts (4) include a haemostatic valve (22), preferably of the tricuspid type at proximal end (6) and/or a haemostatic valve (7), preferably of the tricuspid type at distal end (5). Tricuspid refers to a valve in the shape of a flexible silicon or polymer washer in the centre of which are three slots to enable the leakproof passage of instruments.
