In particular, the present invention relates to a catheter for drainage purposes and a device for positioning the catheter. [Prior Art] In many medical conditions, it is necessary to discharge or release liquid in the body cavity, such as 'urine, blood, and the like. Many catheter designs are available and generally available for this purpose. If the drainage tube is required to act for a long time, such as days, weeks or even months, it is mainly that the catheter can be properly fixed in the body cavity for drainage. A common type of fixed catheter is a conventional c〇pe loop tube or a lockable "lead" catheter. The catheter feature includes a means for forming a crimp (i.e., lead) at the distal end of the catheter once it has been positioned within the body lumen thereby forming an effective means to prevent or prevent the catheter from being withdrawn. For example, the crimp can be formed by pulling a thin wire that secures the proximal end of the catheter and from the lumen of the catheter to its distal end where it exits through an exit aperture positioned adjacent the tip of the catheter. The thin wire re-enters the catheter along the outer surface of the catheter back through a hole of a certain distance through the distal exit hole, and then passes through the interior of the catheter to the proximal end of the catheter, wherein the thin wire "slack end can be grasped by a physician and Take it when pulling. Pulling the thin wire causes the two distally positioned holes to approach each other, thereby forming the curl. Percutaneous renal system is the oldest technique used in the insertion of radiation. It comprises a drainage catheter or tube disposed within the renal pelvis through a subcutaneous injection. The drainage catheter with the percutaneous renal hole is typically the above-mentioned "c〇pe ring, type discharge catheter. 90412-981125.doc f Early methods are very time consuming and require multiple program steps. It must be spent on a week of Yin Bei on this red order ^. ..., and, the technology has been substantially developed and today a program can be implemented in a continuous step-by-time. Although the coupon of the Cope loop catheter ^ ^ + 优 优 ^, due to its use of the curl to have an effective locking function, it still has the disadvantage of M y , 杲 1 . For example, the problem with the Cope ring is that the desired loop is not in the non-expanding system. In particular, the T degree is particularly in the ureter, so it is sometimes blocked in the kidney when the locking curl is obtained. The curling of the lock may require a substantial touch. The urine is a salt-based supersaturated solution that is readily crystallized by the solution when it is in contact with foreign matter such as a material: If this; obstruction and because the extraction thin line travels within the lumen of the catheter =, the fine line will block in the sinking (tetra) crystal. In this case, it may be difficult to hang, if not impossible, to make a 'open'... Coupling the thin line to remove the curl and "open" & Thus the physician may need to perform a more complicated and invasive insertion to remove the catheter.

The first drainage catheter is pushed into the introducer until the catheter plug is in close proximity to the introducer plug, and a loop is formed in the body lumen of the first V-tube end region. In another general aspect, a method of extracting an inner body cavity includes inserting an introducer into a body cavity, inserting a first water conduit into the introducer, and pushing the first drain guide into the introducer Removably attaching a catheter plug to an introducer plug and using the first drainage catheter to draw fluid from the body cavity. The extracting action can further include separating the catheter plug from the introducer plug, withdrawing the first drainage catheter by the introducer, leaving the introducer in the body lumen, and placing a second drainage catheter Insert into the introducer. The introducer includes an introducer plug and a longitudinal passageway through a sheath between the proximal end and the distal end. The plug has a longitudinal passage and is engageable to the proximal end of the sheath. The first drainage conduit includes the catheter plug, a tubular body, at least one elongate member, and an annular member. The tubular body has a distal end region, the elongated member having a transport end and a proximal end. The catheter plug is connected to the tube body near the -12- 90412-981125.doc [S] end region. The ankle extension member has a proximal end and a distal end. The elongate member distally mounts the distal end region of the body, the proximal end of the elongate member being coupled to the annular member and the elongate member passing along the outer surface of the first drainage conduit between the annular member and the distal end region of the tubular body. The first drainage catheter is pushed into the introducer straight-to-shoulder S plug adjacent to the introducer plug, and a loop is formed in the body lumen of the distal end region of the first arch iliac tube. . In another aspect, a method of extracting an inner body cavity includes inserting a guide into the cavity II, inserting the first water conduit into the introducer, and pushing the first introducer ¥ S into the guide, Removably attaching a catheter plug to the guide plug's use to draw liquid from the body cavity using the first drainage catheter, the catheter plug is separated from the introducer plug, and the introducer is guided by the introducer 'The introducer is left in the body cavity and the second drainage catheter is inserted into the introducer.

The first pushes the guide until the catheter plug is in close proximity to the introducer plug and the younger one is located in the first body cavity and the second loop is used in 90412-9Bll25.doc -13 - 1322695 A portion of the distal end region of the first drainage catheter is formed in the second body lumen. This catheter offers many advantages. For example, the catheter can be used to easily and simply form a loop within the unitary cavity - even in chambers where access to the space is limited or limited. Another advantage of the catheter is that catheter replacement is very easy to implement. In particular, this replacement typically does not require the use of ancillary equipment such as wires, anesthesia, and fluoroscopy. Furthermore, the replacement of the catheter can be performed by a nurse outside the hospital, and the doctor does not need to monitor the procedure. A further advantage is that if the pull-out configuration of the thin wire extends along the outside of the conduit tube, it is blocked by, for example, precipitation of urine salts, resulting in the elimination of fine line clogging. This will reduce or eliminate the problems associated with prior art Cope loop catheters, where the thin wire extends over the inside of the catheter. The details of one or more embodiments of the invention are set forth in the drawings Other features and advantages of the invention will be apparent from the description, drawings and claims. [Embodiment] Figures la and lb illustrate a locking catheter 2 of a prior art Cope loop. The conduit 2 includes a discharge liquid flowing through the tube 4.

The p portion 8c extends through the proximal end of the plug tube 4 to exit. The terminology is defined as the guiding point away from the catheter into the body. The term "proximal" is used to refer to the guiding point of the catheter into the body. For example, the distal end of the catheter is indicated. Will be positioned at the catheter end of the body, and the proximal end of the guide indicates that the catheter end will be at or near the guiding point or outside the body. The term "distal area" is used herein to indicate that it will be located in the body and away from the body. The area of the catheter guiding point, and the proximal area, is used herein to refer to an area that is not closer to the guiding point. Furthermore, the proximal end and the distal end of the long member or the thin line are used to indicate the thin wire member/components respectively suitable for the proximal end and the distal end, that is, the distal end of the thin wire may be the actual end of the thin wire or a part thereof. For example, a thin line intermediate area suitable for remote positioning. If the physician pulls the portion of the thin line 8 that extends from the connector 6, the first through point 12 will be pulled in the direction of the second through point M. If the physician continues to pull the thin line 8, the distal end of the catheter 2 will form a loop (ie "lead") (Fig. ib). In this position, the thin line segment 8b will give its length reduced to a virtual zero value. If properly formed in the cavity into which the catheter has been inserted, the loop will provide a reliable means to prevent the catheter from being pulled out. The procedure for positioning the Cope loop locking catheter 2 includes the expansion of the penetrating 'incision of the kidney, and thereafter inserting the catheter 2 into the expanded tissue channel. Thus the catheter remains in the dilation channel and directly contacts the renal tissue. As mentioned above, this prior art catheter 2 has the disadvantage that it is difficult to produce the ring 90412-981125.doc • 15-13225695 because the catheter 2 must be inserted into the cavity to be discharged to a sufficient degree, which would allow for a Complete loop. Thus, the catheter can be clogged in various irregularities, such as in the renal pelvis or ureter when the lumen is a kidney pelvis. If the catheter 2 is clogged with irregular tissue, there is no sufficient space to create the loop, because for example when the thin wire 8 is pulled by a physician, the distal end will not be able to wrap it around. Referring to Figure 2', a set of medical devices 2 includes a dilator (2), an introducer 24-lead (or Cope loop) catheter, and a guide pin or mandrel. The introducer 24 includes a set of camps. j. Lean S 25a and a connecting piece, such as plug 25b (hub). As described in detail below, the dilator _ is positioned to position the device within the venting chamber. The conduit 26 has an extraction means (e.g., a ring member, a stopper or a stop) that is configured to interact with the introducer plug 25b. The stop means 28 can have the form of an annular member or annular member and can be slidably attached to the conduit conduit. From the annular member 28 an elongate member or traction line is advanced to the distal end of the connector 34 (or at a point near the distal end), wherein it extends through the conduit conduit 30, for example by the opposite end Leave, and travel (four) and connect (four) ring members 28. The draw line 32 extends through the conduit conduit by simply pulling the wire through the conduit of the tip, such as by a needle through the tube 35, or by making a hole in the cavity and then pulling the wire therethrough. The traction second line is substantially inelastic so that the loop can be reliably formed. The traction line 32 is coupled to the conduit line 3q by a pair of conduits which can be formed into any suitable device such as a metal strip, a dry agent or a dough. The dilator 22 includes a radiopaque segment 23. For example, this paragraph can be made up of a 1 with 90412-981125.doc

As described in detail below, the radiopaque segment allows the physician to be confident that the introducer 24 is located within the collection system under the fluorescent lens. Although the fluorescent lens is a method of visually observing the introducer in the body cavity, the technique of ultrasonic can also be used to observe the configuration of the medical device (ie, introducer, needle, wire, dilator, catheter) in the body cavity. . Visual inspection of these ultrasonic devices in a body cavity is well known to those skilled in the art. The catheter 26, guide wire 24 and dilator 22 are manufactured from commonly used medical grade plastics using standard techniques. For example, the plastic can be one or more polyurethanes, latexes, and any other polymers, as well as - pebax9 materials. Again, the conduit 26 can be made from more than one material. Different rigid materials can be used to create a conduit 26 having different stiffness in different regions. Preferably, the distal end region of the catheter 26 includes a portion of the catheter 26 that is adapted to form a loop. When a loop is formed, the distal end region of the catheter 26 defines a stiffness greater than the stiffness of the proximal region of the catheter 26, wherein The proximal end region of the catheter 26 includes a portion of the catheter 26 that is adapted to be located within the introducer 24. Materials with different stiffness can be welded at the same time or joined by welding. Alternatively, when the guide f26 is injection molded, a process in which the material is just adjusted in performance is used. If required, the catheter can produce different thicknesses in different sections... Memory metal or spring metal can also be used for the conduit 26. The guide pin or mandrel 27 can be made of any medical grade metal or polymer. 90412-981125.doc 1322695 5H metal can be, for example, non-recorded steel, nickel-Chin or titanium. The polymer can be one or more of the above polymers. The draw thin line 32 can be made, for example, of nylon. Referring to Figure 2W2c, the structure of the conduit 26 can be formed along the length of the tube 3 based on the thin, (4) = point of the tube - a loop. For example, Figure 2b illustrates the thin line passing through the tube 3 at a location distal to the guide. Figure 2c illustrates the thin line 32 passing the tube 30 a set distance near the end of the 4 conduit 26 end.

For example, reference to ^3a_h '% of the catheter can be located in the kidney pelvis without the purpose of taking the kidney pelvis. Initially, a hollow needle 37 is used to percutaneously penetrate the kidney 38 to provide an access path to the collection system 39, such as. Hai kidney moon plate. The penetrating action is completed so that the needle needs to be entered - the renal pelvis 39 (Fig. 33). A wire 42 then passes through the lumen of the hollow needle 37 such that its Z extends into the collection system, which corresponds to a distance of about 4 cm to 5 cm beyond the tip of the needle 37 (Fig. 3b). When the lead 42 is located within the body cavity, the needle is then pumped: (Fig. The dilator 22 is next inserted into the introducer 24, and the dilator and introducer assembly is passed through the guide pin 42 and inserted into the kidney tissue (figure The tissue entering the tissue through the assembly will widen or expand the channel originally created by the needle 37. The tissue is expanded as much as possible in an atraumatic manner, but must be in the introducer cannula 25a and by the introducer There is a smooth transition between the expanders extending outwardly of the cannula. For example, the introducer cannula can be tapered to have an inner diameter that is at least greater than the outer diameter of the expander 22. This is most easily Tilting the distal end of the sleeve 25a to a relatively small angle is achieved, the angle 90412-98IJ25.doc m is >45, preferably less than 30. Preferably, it is less than 2 (Γ. Usually, the angle is more The smaller the better, and only the manufacturing technique limits the angle value. Of course, if the sleeve 25a is made of a sufficiently thin material, if the expander 22 is well suited for mounting in the sleeve 25a, a tapered shape may not be required. In order to reduce the friction between the introducer 24 and the expander 22, a water absorption (hydr〇f Il) A friction coating can be applied to the dilator 22. The dilator 22 can be coupled to the plug 25b of the introducer 24 through a plug at the proximal end of the dilator 22. Further, the distal end of the dilator 22 preferably forms a The sharp edge and the inner diameter of the dilator 22 match the diameter of the wire. The assembly of the dilator 22 and introducer 24 can then be advanced slightly toward the collection system, where the physician can selectively fluoresce the lens, ultrasonically Or verifying that the non-transmissive section 23 is located in the collection system (Fig. 3e) because the dilator 22 is located inside the introducer 24 such that the radiopaque section 23 is located at the distal end of the sleeve 25a. The physician can confirm when the cannula 25a is located just inside the collection system by looking up the radiopaque segment under the fluorescent lens. The dilator 22 is then withdrawn ' leaving the introducer in the collection system (Fig. 3f) The catheter 26 is then introduced into the introducer 24 (Fig. 3g). ^To facilitate introduction of the catheter into the introducer' the rigid guide pin 27 is first inserted into the catheter to provide longitudinal stiffness and support the catheter. Thus, The conduit 26 is less likely to block in the guide 24 'No A blockage may occur due to the flexibility of the catheter. To reduce friction between the introducer 24 and the catheter 26, a friction reducing coating may be applied to the catheter line 30. Further, a gasket is preferably disposed in the plug. Between 3 6 and 25b to prevent leakage. In general, the guide 24 and the assembly guide catheter subsystem must be flat 90412-981125.doc 19 slip and easily bend without damage. When =6 has been inserted The guide member 24 to the annular member 28 abut the guide: when the time is as shown in Fig. 3g, the thin, (4) will be tight = the elongation of the thin line 32 is the length of the (four) length of the ring member 28 and The abutment point to the thin line of the plug 25b is equal in length to the junction of the conductor 34 just off the sleeve. Since the wire 32 is elongated and cannot be extended due to its lack of elasticity, and because the distal connection point 34 cannot be advanced by the distal tip of the introducer, the catheter is advanced to advance the guide wire to create the conduit 3 Loop. During the formation of the loop, the guide pin 27 must be removed to prevent interference with the loop. Alternatively, the guide pin 27 can be maintained in position but it must not advance with the conduit 26. As the catheter 26 advances further into the introducer 24, the catheter line 30 located behind the point μ will thus be removed by the introducer and pass through the point 34, whereby the loop will begin to form (Fig. 3h) . The physician advances the catheter 26 until the catheter plug 36 mates with the introducer counterpart plug 25b. In this position, the plug and 25b can each be coupled together, for example by a thin wire bond, a bayonet lock or by any other locking means. Thus, the catheter is locked into the collection system (i.e., the kidney pelvis) and the loop effectively occupies the catheter into the kidney. The procedure for configuring the conduit 26 can be summarized as follows: (1) using a needle to create a passage through the tissue to the cavity to be discharged; (2) inserting a wire through the needle and advancing the wire into the cavity; (3) removing the And passing the wire through an expanded state and an introducer and expanding the tissue; (4) removing the expander and passing through a catheter having a pulling wire connected to the distal end thereof and passing through the wire into the catheter; 5) Stop the insertion of the conduit when the fine wire connection point is located just above the distal guide 90412-981125.doc • 20· 1322695; (6) be sure that the thin wire will elongate and it will be fixed in the -extended position; (7) Advancing the catheter into the introducer to form the loop of the distal guide (IV); (8) coupling the catheter and the introducer after the required size has been formed; and optionally, (9) Fixing the introducer/catheter assembly to the patient's skin.

(7) positioning an introducer in the channel; (3) inserting - having a pull wire attached to the distal end of the catheter and (4) confirming that the traction thin wire is elongated and when the thin wire connection point is located just beyond the outlet hole of the catheter, it is confirmed that it will be fixed in the extended position; (5) the catheter is advanced and guided And thereby forming a loop of the distal catheter opening; and (6) locking the catheter in the position when the desired size loop has been formed. Figures 4a-d illustrate the interaction between the conduit 26 and the introducer 24 which primarily forms the π a- m 夂 夂 夂. Initially, the conduit 26 leads into the V-state 24 until the ring: the piece 28 remains on the connector 25b (Fig. Tu Tian "_ IPU". At this point, the distal tip of the catheter extends slightly outwardly from the introducer and the spurs are tightly tied to the thin line. The distance between the connection 25b and the connector 36 is ... indicating the circumference of the loop formed. Furthermore, as the catheter advances, the guide f combination extends beyond the guide 90412-98H25.doc Γ 1 1322695 and the distance between the two tabs 25b, 36 will be approximately equal to d. The physician then pushes the catheter 26 slightly further into the introducer 24. Since the annular member 28 remains in the connector 25b and because the draw line 32 is already tight, further advancement of the conduit 26 will cause the loop to begin to form (Fig. 4b). This distance is reduced to a distance I as the catheter advances. As mentioned above, the reduction in distance 4 is approximately equal to the amount by which the catheter extends beyond the introducer. As the catheter % advances further within the introducer 24, the draw line 32 maintains a substantially fixed length that maintains the distal end of the catheter proximate the distal tip of the introducer. Thus, as the conduit line 30 advances through the guide (Fig. 4c), it will begin to form a large loop. When the distance t is reduced to - distance seven, an approximately equal amount advances through the introducer. Finally, pushing the catheter 26 completely into the introducer 24 will entrap the annular member 28 between the tabs 25b, 36 and lower the distance. When the annular member 28 is trapped between the connecting pieces 25b, 36, the ring is round; The circumference of the loop is set by increasing or decreasing the length of the draw line. For example, to reduce the circumference of the loop, the length of the draw line is reduced and the circumference of the loop is reduced, and the length of the (4) thin line must be increased. Typically, the introducer 24 has a length that is approximately equal to the length of the elongate member or wicking wire 32 that is coupled to the traction device or ring member and the elongate member by the elongate member. More specifically, the length of the through member is connected to the traction means and the distance between the distal end of the tubular body and the length of the elongated member or the thin wire 32 is 10 mm and longer than the length of the member. Lead length. The advantage of the medical device 2 is that the catheter 26 can be easily changed 904J2-981125.doc • 22. For example, if the catheter becomes blocked. In fact, the catheter 26 can be changed by a single device without the use of any auxiliary devices and equipment, such as anesthesia. In particular, the conduit 26 is altered in the following manner. Initially, the nurse or physician releases the lock between the introducer 24 and the catheter 26 shortly and is withdrawn by the introducer. The catheter 26 is withdrawn until it does not extend beyond the introducer to completely eliminate the loop "because the traction line 32 travels along the outside of the catheter 26 in the space between the inner wall of the introducer and the outer surface of the catheter. Any salt will not be sufficient to precipitate to secure the wire to the catheter or introducer. The salt precipitation that solidifies the fine line to the guide is the biggest problem with prior art catheters because the fine line travels almost entirely inside the catheter. When the catheter 26 has been removed, a new catheter % is provided which is "inserted" into the inner cavity so that the guide is rigid enough to be pushed and the catheter is then reinserted. The guide pin 27 is then removed. Or contracting, and the catheter 26 is advanced to the introducer 24 such that the loop begins to form at the distal tip of the catheter. Although the medical device 20 will function as described above, the modified example works well. For example, The catheter 32 need not be secured to the annular member 28. Instead, the capillary line 32 can be provided as a single thin wire that can be attached to the distal end of the catheter pathway 30 rather than being secured at its proximal end. Outside the annular member, the thin wire must be fixed, for example, to the tabs 25b and/or 36. In such an implementation, it must have some indicator marks on the thin line to be able to discern when the 'tail point of the thin wire connection is located The desired position, that is, just beyond the distal exit opening of the conduit line. This discrimination can be achieved by a simple colored marking on the thin wire or tube so that when the thin wire is connected to the distal end of the conduit 30 has been reached Required position At this point, the sign will reach the proximal insertion opening of the introducer plug 90412-98l125.doc -23- 1322695 or the connecting piece 25b. At this point, the physician or nurse fixes his thin wire end at the introducer plug 25b, any suitable device such as a clip provided on the connector or interposed with the thin wire into a very small slit in the connector, wherein the diameter of the slit is greater than the width of the slit, forcing the wire to frictionally engage the configuration Many other fixtures will be feasible as long as they provide the attachment of the wire to the plug 25b. Referring to Figures 5a-c, in a further implementation, a guide tube 24 is used in conjunction with the guide 24, including a connector 45 and conduit 50. The conduit 5 includes an opening 55 for discharging liquid at the distal end 60 of the conduit 40. The conduit 5 also includes a first set of openings 65' at the distal end 60 of the conduit. a second set of openings 7A of the set of openings 65, and a third set of openings 75 adjacent to the second resistive opening. The drain conduit 40 also includes a stop member 8 for slidably mounting the line 50. 〇. The drainage catheter 40 Unlike the drainage conduit 26, a traction thin wire 85 is conveyed from the outside of the conduit to the inside of the conduit and then back to the outer side of the conduit. In particular, the traction thin wire 85 has two ends 9〇, 95, and its two ends , for example, using a sleeve, adhesive or other attachment means, connectable to the 裒幵v member 80. The 6 squat pull line 8 5 is advanced from the annular member 8 至 to the third set of openings 75, and proceeds to The inner lumen of the catheter 4. The traction thin wire 85 is sent out through the second inner opening 7 of the inner cavity. The traction thin wire 8 5 then travels along the outer side of the catheter 40 until it reaches the first set of openings 65. At this point the fine line enters the lumen of the catheter through the first set of openings. The distance between the first set of openings and the second set of openings 70 is approximately equal to the circumference of the loop when the catheter 40 is inserted into the introducer 24. The distance between the third set of openings 75 and the connector 45 is about 90412-981125.doc IS 1 -24- 丄 ^2695 is equal to the distance between the first set of openings 65 and the second set of openings 7〇. By pulling the traction wire 85 to the second barrier opening 70', when the catheter 4 and the introducer 24 are positioned within the body cavity, the traction wire will rub against the distal end of the introducer. This is an advantage because it extends the life of the thin wire and limits the failure mode for replacing the catheter. Referring to Figure 5d, in use, the catheter 4〇 enters the introducer 24, which is already in the integral cavity until the connector 25b contacts the annular member 8〇, at which point the draw thin wire 85 will be tightened . The catheter 4 is further pushed into the guided state 24 such that the connector 25b urges the annular member 80 along the conduit conduit 5 in the direction of the connector 45. Referring to Figure 5e, the catheter 40 is fully pushed into the introducer 24 until the connector 25b annular member 80 and the connecting benefit 45 are compressed together such that a loop is formed at the distal end 60 of the catheter 40. The second set of openings 7 is positioned along the length of the conduit conduit 5 at a distance from the distal end such that when the catheter buckle is fully pushed into the introducer 24, the distal end of the introducer approaches the opening 7 Hey. As such, the traction wire 85 is unlikely to rub against the distal end of the introducer 24 beyond the distal end of the catheter 4 and the introducer 24 remaining in the body cavity. The thin wire 8 5 will damage the pulling wire and cause it to break. Although Figure 5a illustrates a particular distance between the second pair of openings 7〇 and the third pair of openings 75, the distance can be increased or decreased. For example, the distance can be set at about one knives to thereby configure the second set of openings to approach the distal end 6〇 such that the traction line is located within the lumen of the catheter 4G for only - centimeters. This is beneficial in reducing the length of the draw line which is capable of having a salt > which, as described above, enables the draw line to be positioned in the lumen of the catheter. Even if the traction line is only one centimeter fixed the inner 90412.981125.doc -25-cavity' so the physician will be able to easily loosen and remove the loop in the catheter so that the physician can easily withdraw the catheter from the introducer. Referring to Figures 6a and 6b, in a further embodiment, a drainage lumen 100 capable of discharging a two-body lumen can be configured with the introducer 24 and includes a connector 105 and a conduit 11A. The line 11A includes a first set of openings 115 at the distal end 12〇 for discharging the first body cavity and a first set of openings 125 at the intermediate section 13〇 for discharging the liquid of the second body cavity. The first set of openings % 115 are formed in the first loop U5, and the second set of openings 125 are formed in a second loop 140. The first loop ι35 is formed in the conduit 110 using standard methods, such as by configuring the conduit 1 on a curved mandrel and configuring the assembly in a furnace to conduct a curve in the mandrel to the conduit . The conduit 1 also includes an annular member 145, a draw line 15A, and an opening 155 through which the draw wire passes. Pushing the catheter 100 into the introducer 24 will cause the annular member 145 to slide along the conduit 1 and form a loop. The conduit may also include a first loop 135 disposed thereon. The radiopaque strip is 16 turns so that the configuration of the guide can be viewed under the fluorescent lens to ensure that the first loop is properly positioned within the first body cavity to be discharged. The i-director 100 is used, for example, to discharge the kidney and the bladder. The catheter 1 is inserted in a manner similar to the above-described drainage catheter. Initially, however, the first loop 1 3 5 passes straight through the crucible guide 24. Optionally, the conduit i can be disposed on a wire. In either case, the catheter 1 is advanced until the first loop 135 is located within the bladder. In doing so, the introducer connector 2 pushes the annular member 145 externally and forms a second loop 14〇 within the kidney. In a further implementation, the traction line does not have to be fixed or fastened close to the 90412-981125.doc IS 1 • 26- guide your tip. If you want to be in the kidney tube, drain the route / below, for example, close to the urinary collection system.] It must provide a fairly long tip to make JL as close as possible! The cents exceed the input of the receipt too: make it, which is good for positioning, the point of the sea... Although for example, a circle is provided at the input point of the collection system to raise it. The fine wire of the catheter is fixed to the distal end of the It f a pilot tube. - The point just above the guide loop embodiment is described. Nonetheless, the I & correction can be achieved by deviating from the spirit and scope of the present invention, for example, Figure 7, the knot of the thin line extending along the two sides of the pipe 3 "extending along the pipe - side" to connect the The end of the thin wire is connected to the distal end and the other end to the stop or ring member 28. However, this would require that the connecting device 17G be located at the tip, for example using a - sleeve, a metal strip or molding, etc. 'To ensure that the thin wire end is tightly connected to the pipe. The metal strip can be a radiopaque metal strip so that it can be viewed under the fluorescent lens. Although the drawn thin wire travels along the outside of the duct as shown, its structure The drainage catheter 4 can be advanced to the inside or outside of the catheter in the manner described above with respect to the drainage catheter 4 of Figure 5a. Similarly, although the catheter has been described with reference to a renal pelvic catheter insertion application, it must be understood that the catheter is extensive except for use only in the kidney pelvis Application. For example, the catheter function will be able to discharge other body cavities of humans or animals such as, but not limited to, the bladder, gallbladder, abscess, abdominal cavity and chest cavity.
