Abstract

A medical catheter device (14) in which a guidewire (16) is receivable in a guidewire lumen which is slotted (15) in the longitudinal direction of the catheter (14) and has at least one lumen opening (13) located between the catheter ends into which the guide wire (16) is insertable into the guide wire lumen and from which the guide wire (16) can be guided out of the guide wire lumen, characterized in that said lumen opening (13) extends obliquely through the lumen opening (13) the lumen opening (13) extending, on its upper side open guidewire guide member (4, 5) can be used or inserted.

Description

  • The present invention relates to an apparatus for a medical catheter in which a guide wire is receivable in a guide wire lumen slotted longitudinally of the catheter and having at least one lumen opening located between the catheter ends into which the guide wire is insertable into the guide wire lumen and from which the guidewire can be guided out of the guidewire lumen.
  • Devices of the abovementioned type are already known in connection with ERCP catheters used for endoscopic retrograde cholangiopancreatography (see, for example, US Pat. DE 697 38 642 T2 . DE 697 34 672 T2 ), also referred to as short-wire / quick-release biliary catheters. In these prior art devices, the guidewire is received within a guide wire lumen contained within the catheter which is slotted over substantially the entire catheter length and which has a lumen opening located between the catheter ends for insertion of the guidewire into this guidewire lumen into which the guidewire is threaded into the guidewire lumen to then be advanced in the guidewire lumen toward the catheter distal end. However, in order to guide the guide wire out of the relevant lumen opening, ie when the guide wire is pushed from the distal end of the catheter through the guide wire lumen in the opposite direction from the previously considered insertion direction, the catheter must be bent in the area of said lumen opening so that the guide wire is therefrom Lumen opening can escape. If such a kinking were omitted, namely, the guide wire would continue to be moved only along its guide wire lumen.
  • This manipulation of the catheter for guiding the guide wire out of the relevant lumen opening is sometimes considered undesirable. Rather, there is a desire for a procedure which avoids this unwanted handling.
  • Although there are already known biliary catheters ( DE 600 24 206 T2 . DE 601 08 014 T2 ), which have a so-called hood device in the region of a lumen opening of a guide wire lumen lying between catheter ends. However, this hood device only allows insertion of a guide wire into the hood device, but not a lead out of the guide wire from the relevant hood device, ie when the guide wire is pushed in its opposite direction of insertion previously considered direction from the distal end of the catheter through the guide wire lumen. The reason for this is firstly that the hood device, together with an additional working lumen, provides access to a single lumen to a distal catheter end. On the other hand, the reason is that the hood device has a disposable lip seal on its end projecting into the single lumen of the catheter, which can pass through the guide wire only in its insertion direction
  • In addition, an insertion tool for (re) inserting a guide wire into a guide wire lumen of a catheter with an insertion funnel slotted on its upper side is already known ( DE 600 35 936 T2 ). However, this insertion tool also does not allow leading out of the guide wire from the relevant insertion funnel, that is, when the guide wire is pushed in the direction opposite to its normal insertion direction from the catheter distal end through the guide wire lumen. Also in this case, the catheter would have to be bent in the region of the insertion funnel, so that the guide wire can emerge there from the lumen opening.
  • The invention is therefore based on the object to show a way, as in a device of the type mentioned can be done while avoiding the considered in the considered known devices as undesirable handling of the catheter, in a simpler way, a safe lead out a guidewire to reach a lumen opening present in a guidewire lumen of a catheter between its ends when the guidewire is pushed from the distal end of the catheter through the guidewire lumen in the opposite direction to its normal insertion direction in the lumen opening in question.
  • The above object is achieved in a device of the type mentioned in the present invention, characterized in that in said lumen opening with respect to the longitudinal direction of the catheter obliquely through the lumen opening extending, on its upper side open guidewire guide member is used or used.
  • This provides the advantage that the guidewire guidewire is sure to insert the guidewire into the guidewire channel at the distal catheter end as well as when the guidewire is withdrawn in the opposite direction to its normal insertion direction from the distal end of the catheter, both during its normal insertion through the respective lumen opening allowed to lead out. A kinking of the catheter in the region of said lumen opening is in any case not required here.
  • Expediently, the guide wire guide part extends with its end protruding into said lumen opening into the vicinity of the bottom wall of the guide wire lumen. This has the advantage that the mentioned lead out of the guide wire from said lumen opening of the guide wire lumen is additionally improved.
  • According to a further expedient development of the invention, the guidewire guide part, at least in the region of its insertion into said lumen opening, has a width which corresponds approximately to the width of the area of the guidewire lumen receiving the guidewire guide element. As a result, the security is further increased that the aforementioned lead out of the guide wire from said lumen opening of the guide wire lumen safely, so easily done.
  • The guide wire guide part preferably has an at least approximately semicircular cross section, a U-shaped cross section or a V-shaped cross section and is made of plastic or metal. As a result, the advantage of a particularly low design effort for the guide wire guide is achieved.
  • According to a further expedient development of the invention, the guide wire guide part is received by a receiving member which is open to the upper side, which can be attached to the catheter in the region of said lumen opening and / or fixedly attached to the catheter by means of a shrink tube. This results in the advantage of a particularly effective connection of the guidewire guide member to the catheter.
  • Preferably, the receiving member is provided with a clamp-like gripping member for gripping the catheter at least partially surrounding or gripping it. This allows a particularly simple attachment of the guidewire guide member to the catheter, either only temporarily or permanently, for example by an additional adhesive bond.
  • Conveniently, the receiving member and the clip-shaped attachment member made of plastic or metal. This has the advantage of a particularly small design effort for the formation of the receiving member and the bracket-mounted attachment part with it.
  • With reference to drawings, an embodiment of the present invention will be explained in more detail below.
  • In the drawings show
  • 1 a greatly enlarged side view of an embodiment of a device according to the invention,
  • 2 a greatly enlarged plan view of the device according to 1 .
  • 3 a greatly enlarged sectional view of the device according to 1 according to the in 2 indicated section line AA,
  • 4 a greatly enlarged front view of the device according to 1 and 2 .
  • 5 a greatly enlarged perspective view of the device according to 1 to 4 without a guidewire and
  • 6 a greatly enlarged perspective view of the in 5 shown device after attachment to a medical catheter and receiving a guide wire which is inserted into a guide wire lumen of the catheter or led out of this.
  • Before referring to the embodiment of the device according to the invention shown in the drawings, it should be noted that the same elements or devices are denoted by the same reference numerals in all drawings.
  • In the 1 to 4 Guidewire guide device according to the invention shown on a greatly enlarged scale, hereinafter referred to as device for short, is generally designated by the reference numeral 1 designated. The device in question 1 consists of a first guidewire wrapping cheek 2 and one with this in one in the 1 to 3 On the right-hand side of the illustrated second guidewire wrapping cheek 3 , Both guidewire wrapping cheeks 2 and 3 lie opposite each other, as shown in the plan view 2 is apparent. To these two guidewire containment cheeks 2 and 3 close in the right part of the 1 to 3 a first handle part 7 and a second handle part 8th the device 1 at. The handle parts 7 and 8th the device 1 As will become apparent, for one of two guidewire guideways 4 and 5 existing guidewire-Leitteil in a sense a recording member.
  • To the aforementioned handle parts 7 and 8th joins the right side of the 1 to 3 one with the device 1 coherently formed cones 6 at. This pin 6 can, as related to the description of the 6 will be apparent to a fixed attachment of the device to a medical Are used catheter, for example by means of a pin 6 and the respective catheter surrounding shrink tube.
  • Between the two guidewire enclosing cheeks 2 and 3 is in the device 1 a guidewire leader embedded, consisting of a straight guidewire leader 4 in the 1 to 3 shown on the left and from this immediately adjacent bent guide wire guide 5 in the 1 to 3 on the right. The two guidewire guideways 4 and 5 , which are made of either plastic or metal, are open to their respective top. They may have a semicircular, a U-shaped, a V-shaped or other shaped cross section in the form of a channel, such as a quadrangular cross section. For the materials for the two guidewire guideways 4 and 5 Of course, these are biocompatible materials.
  • The guidewire guideways 4 and 5 serve, as their name implies, to an in 1 to 5 not shown guidewire - as in 6 shown and there with 16 is - to guide, so to lead, on the one hand, when this guide wire is inserted through a provided between the ends of a medical catheter opening in a guide wire lumen contained in the catheter, and on the other hand, when the guide wire through the relevant Opening is led out of said guidewire lumen. The last-mentioned opening of the guide wire lumen can be a second opening of the guide wire lumen between the ends of the catheter. In this case, two devices can then be used 1 be attached to the catheter according to the invention. The guidewire guideways 4 and 5 every device 1 thus each fulfill a dual guidewire guiding function, namely for introducing a guidewire into a guidewire lumen and for guiding the guidewire out of the guidewire lumen.
  • The straight guide wire guide 4 stands with his in 1 to 3 left end of the left outer side of the two guidewire enclosing cheeks 2 and 3 from and is relative to the bottom of the device 1 obliquely downwardly inclined, as shown in the sectional view according to FIG 3 is clearly visible. The angle of inclination of the straight guide wire guide 4 with respect to the bottom of the device 1 may for example be 10 °. The curved guide wire guide 5 is about the middle of the device 1 in the longitudinal direction of a Bahnumlenkteil. The bent guidewire Leitteil 5 terminates at the top of the device body of the device 1 like this 3 and 4 is apparent.
  • As already mentioned, the guide wire guide part extends 4 between the first guidewire wrapping cheek 2 and the second guidewire wrapping cheek 3 , Between these two guidewire enclosing cheeks 2 and 3 there is an open passageway 9 through which the two guidewire containment cheeks 2 and 3 to the top and bottom of the device 1 in the left area of the device according to 1 to 3 are open.
  • To the two guidewire enclosing cheeks 2 and 3 close to the right side of the 1 to 3 two handle parts of the device 1 on, a first handle part 7 and a second handle part 8th , Between these two, for detecting the device 1 serving handle parts 7 . 8th There is a first transition area 11 and a second transition area 12 between the two handle parts 7 respectively. 8th for forming a guide wire guide receiving area, here for the bent guide wire guide 5 , but also for a short piece of this connected straight guidewire Leitteiles 4 , The body of the device 1 is thus in the range of the two handle parts 7 respectively. 8th connected.
  • How out 3 and 4 indicates is located on the bottom of the device 1 , and more precisely between their handle parts 7 . 8th an open to the bottom catheter abutment area 10 , This catheter abutment area 10 here has a semicircular or U-shaped cross-section. With the help of this catheter system area 10 can the device 1 in the region of a lumen opening of a guide wire lumen of a medical catheter are also attached to this, for example by simply plugging it onto the catheter or by fixing it to the latter by means of an adhesive bond. The device 1 with the catheter abutment area 10 can act as a clamp-shaped attachment part, which at least partially surrounds or grips for attachment to the catheter. These parts or areas of the device 1 can be made of plastic or metal. The materials for the two parts or areas are of course also biocompatible materials.
  • Let us now consider the perspective views shown on an enlarged scale 5 and 6 considered. The 5 shows the device 1 as they are in the 1 to 4 before being attached to a medical catheter and without a guidewire. This device 1 thus represents the device that can be used in conjunction with a medical catheter in which a guide wire is receivable in a guide wire lumen slotted in the longitudinal direction of the catheter and at least one lumen opening lying between the catheter ends, into which the guide wire is insertable into the guide wire lumen and out of which the guide wire can be guided out of the guide wire lumen.
  • In 6 is that out 5 apparent device 1 shown as with the protruding end of the straight guidewire Leitteiles 4 in an opening 13 a guidewire lumen of a medical catheter 14 is introduced. The guidewire lumen of the catheter 14 has between its ends in the longitudinal direction a longitudinal slot 15 through which a guidewire inserted into the guidewire lumen 16 can be pulled out. This pulling out of the guidewire 16 occurs in the initially mentioned ERCP catheter usually when after laying the guidewire 16 by means of the catheter 14 in a patient with other medical instruments using the inserted guidewire 16 is worked, such as by means of a papillotome or a balloon catheter.
  • The guide wire guide 4 runs with his in the said lumen opening 13 protruding end to near the bottom wall of the guidewire lumen. In addition, the guide wire guide member 4 at least in the area of its introduction into said lumen opening 13 a width that is about the width of the guide wire guide 4 receiving portion of the guidewire lumen corresponds. This is a safe insertion of the guide wire 16 in the guidewire lumen but above all, a safe lead out of the guidewire 16 ensured from the guidewire lumen.
  • Out 6 it also appears that the device 1 with her thong 6 by means of a pin 6 and the catheter 14 enclosing heat shrink tubing 17 with the catheter 14 is firmly connected.
  • The guidewire 16 can, as already mentioned above, by means of the device 1 into the guidewire lumen of the catheter 14 introduced at one point or guide wire lumen opening easily and / or out of this guide wire lumen at the same location or by means of another device 1 at one of said one location spaced apart along the catheter 14 provided second point or guide wire lumen opening are easily brought out, without causing it each a kinking of the catheter 14 requirement.
  • In the drawings is an embodiment of the device 1 represented according to the invention on a greatly enlarged scale. In practice, the device is 1 However, in their dimensions designed much smaller than shown here. So has the medical catheter 14 an outer diameter of between about 1.5 mm and 2.5 mm, depending on the application. Accordingly, the catheter abutment area 10 dimensioned accordingly. This results for the device 1 in practice a height and width dimension of about 5 mm and a length without the projecting straight straight guide wire guide member from his body 4 from about 20 mm to 40 mm. The straight guide wire guide 4 can from the device 1 protrude about 10 mm.
