Description
MEDICAL DEVICE WITH IMPROVED WIRE GUIDE ACCESS
Description Technical Field
This invention relates to medical devices, more particularly to catheters used in surgical procedures. Background of the Invention Sphincterotomes are used in the biliary system as part of an Endoscopic
Retrograde Cholangiopancreatography (ERCP) procedure when the Sphincter of Oddi becomes constricted due to disease or trauma. The sphincterotome, which is typically introduced through the working channel of an endoscope, serves both to cannulate the ductal system and enlarge the opening by delivery of electrical current to a cutting wire. Most standard sphincterotome models, e.g., the MINI-TOME PC™
(Wilson Cook Medical, Inc., Winston-Salem, NC), include a wire guide side port connected distal to the handle into which a wire guide is introduced once access is obtained to the biliary system. The wire guide provides continual access across the sphincter as well as a means to exchange other devices that may be used. The wire guide port usually contains a luer fitting for injection of contrast media or other liquid materials. Unfortunately, this must be done with the wire guide removed so that the syringe or delivery apparatus can be coupled to the side port. Adding a separate fitting on the side port for the wire guide would create a portal for leakage of material, especially when contrast is being injected therethrough. To maintain separate injection and wire guide lumens, in addition to the required lumen for the electrical conductor wire, either results in either smaller lumens than would be optimal or necessary, or requires that the sphincterotome catheter be made larger, also something that is not desirable, especially for a device used within an endoscope. The same problem can be found in other devices, such as balloon catheters, and retrieval devices, such as baskets. Accommodating the control member of the apparatus, the wire guide, and still provide for the injection of contrast media, requires three separate pathways. Unfortunately, providing for all three to be simultaneously operable within a device is often unacceptable due to size
constraints. What is needed is a medical device, such as a sphincterotome, that utilizes a control member, that can allow the wire guide to be used while the fluids (e.g., contrast media, saline) are being injected, without requiring a third lumen such that the device will pass through a standard endoscope. Summary of the Invention
The foregoing problems are also solved and a technical advance is achieved with a medical device, such as the illustrative sphincterotome, having a side port assembly which includes a first port, such as a standard luer lock fitting, which is adapted for injection of fluids or infusate (a first pathway), and a second port, such as a Tuohy-Borst fitting, that is configured for introduction of a standard medical wire guide (a second pathway) where the fitting on the second port can be made to seal around the wire guide to prevent the passage of air or fluids, while still permitting longitudinal movement of the wire guide. The first and second ports communicate with a first lumen of the catheter portion, such as via a shared first passageway (e.g., a cannula), while a second passageway lumen of the catheter portion contains the controlling element apparatus (e.g., electrical conductor (sphincterotome wire), actuating mechanism, inflation lumen(s), etc.) of the device (the third pathway), which may extend to the proximal handle of the device via a second passageway. Combining the fluid pathway and the wire guide pathway into a single passageway within the apparatus, permits the second pathway to be dedicated to housing the control apparatus. Otherwise, a third large lumen would have been required to accomodate all three pathways, thereby increasing the diameter of the catheter. By making the wire guide pathway (second port) sealable, such as with a Tuohy-Borst fitting, constrast media, saline, water, or other liquid media can be injected around the wire guide. For example, in the illustrative sphincterotome, the present invention allows a wire guide to be preloaded into the sphincterotome prior to the cannulation and cutting procedure, advantageously making the entire procedure easier and quicker to perform. In addition, having the preloaded wire guide extending from the distal tip, increases the physician's ability to cannulate closed sphincters and other strictures due to the smaller diameter of the wire guide. The same concept can be extended to other types of devices used with wire guides, such as balloons,
catheters, baskets, snares, deflectable devices, etc., wherein the controlling element is disposed in the second passageway, while the wire guide and injected fluid share the first passageway. Brief Description of the Drawings

FIGs. 1 -2 depicts a medical apparatus 1 0 of the present invention, such a§ a sphincterotome assembly, comprising a medical device 1 1 , such as an electrosurgical device or sphincterotome, comprising a handle assembly 14, an elongate portion 20, which in the illustrative embodiment is a 6 Fr sphincterotome catheter (tapered distally to 4.5 Fr tip), and a working member 36, which comprises a cutting wire in the in the illustrative embodiment, situated about the distal portion 9- of the catheter portion 20. The handle assembly 1 4 is used herein to generally refer to the proximal portion of the device from which the operator manipulates the device 1 1 and through which all ancillary devices and materials are introduced. The handle assembly 1 4 includes a side port assembly 1 3 that further comprises a first port 1 6, such as a standard luer lock fitting for the infusion of fluids or infusate, and 5sealable, second port 1 5, such as a standard Tuohy-Borst fitting, that can be used for the introduction of a wire guide 1 2 which is typically used during a sphincterotomy procedure, such as to cannulate a stricture at the Sphincter of Oddi. In the illustrative embodiment, the side port assembly 1 3 is conveniently located distal the grasping portion 40 of the handle assembly 1 4. As depicted in FIG. 2, the ffist and second ports 1 5, 1 6 function as the proximal access points to the first pathway 37 for fluid infusion and the second pathway 38 for the wire guide,
respectively. Both pathways 37,38 feed into a shared first passageway 26, such as the illustrative tubular conduit or cannula 46, (typically thin-wall stainless steel) that in turn, communicates with a first lumen 22 which generally extends throughout the catheter portion 20 of the device 1 1 . The cannula 46 comprising the first pδssageway 26 serves to guide and protect the wire guide 1 2 as it traverses the first passageway 26 and feeds into the first lumen 22, as well as providing a conduit to carry the fluid comprising the first pathway 37 as the two pathways 37,38 converge within the first passageway 26. The second lumen 23 of the catheter portion 20 serves to accommodate a third pathway 39, which comprises a control member 24 tβat extends distally to operate or activate the working member 36 of the device 1 0. In illustrative sphincterotome 1 1 of FIG. 1 , the control member 24 comprises the electrical conductor or wire 24 that extends to the distal portion 34 of the device 1 1 , where it becomes the cutting wire 36 used to burn or slice through tissue forming a stricture and enlarger the opening. In the illustrative embodiment, the second £5ssageway 27 includes an optional cannula 41 that houses and protects the sphincterotome wire 24 within the side port assembly 1 3 of the handle portion 1 4. Proximally, the sphincterotome wire 24 connects inside the handle assembly 1 4 to a standard electrical connector 25 located on the side of the handle assembly. Distally, the first and second passageways 26,27 connect with the proximal end 31 2Φthe sphincterotome catheter portion 20, thereby communicating with the first and second lumens 22,23, respectively. To provide further protection to the wire 24, the distal portion 42 of the second passageway 27 is enlarged at the junction with the second lumen 23 of the sphincterotome catheter. The cannula 46 comprising the first passageway 26 extends into the first lumen 22, providing a means of 6tachment and reinforcement at the junction of the passageways 26,22. As shown in FIG. 1 , an outer sleeve 30 is typically placed over this junction to provide added reinforcement and support. It should be noted that the illustrative sphincterotome is merely exemplary and one skilled in the medical arts should be able to conceive of design variations that still would fall within the scope of the invention. 30 FIG. 3 depicts a cross-sectional view of catheter portion 20 of the sphincterotome 1 1 , containing a first and a second lumen 22,23 as shown in FIG.
3. Typically, the first lumen 22 is somewhat larger that the second lumen 23 for the purpose of accommodating a wire guide 1 2, while having sufficient space to permit the delivery of fluids, such as contrast media or saline, therearound. In the illustrative sphincterotome, the second lumen 23 diameter is generally about 0.023". Irδorder to accommodate a standard 0.025" wire guide 1 2 (actual diameter 0.020" to 0.025"), the first lumen 22 would preferably have a diameter of about 0.040" to 0.044", with a more preferred diameter of 0.041 " to 0.042". Generally, this diameter still permits a viscous fluid, such as most contrast media, to be infused though the remaining space of the lumen 22 with the wire guide 1 2 in place. These tKEmensions are merely exemplary, and can be appropriately scaled upward or downward, depending on the size of the wire guide 1 2 used, and the diameter of the working channel of the endoscope. The cross-sectional shape of a particular lumen 22,23 is not especially critical for an understanding of the invention and may be round, "D" or crescent-shaped, or some other configuration. While it generally most tlδsirable to limit the number of lumens to keep the O.D. of the device 1 0 as small as possible, particularly if it is to be used within an endoscope having a channel size of 2.8 mm, additional lumens may also be included, if desired such that the pathways 37,38,39 of the device are distributed in some other manner or combination. Restricting the number of lumens to two is preferred, however, as long 2§ the design allows for continual presence of a wire guide during infusion of fluids, such that the wire guide 1 2 need not be removed and can be pre-loaded, if desired. In the illustrative embodiment of FIG. 1 , a standard wire guide 1 2 (e.g., a standard biliary .025" PTFE-coated nitinol wire guide) is shown preloaded into the sphincterotome 1 1 via the first port 1 6. Depicted in FIG . 2, the port 1 6 includes a 2§aling mechanism 32 comprising a seal 28, such as an o-ring, and a tightening component 1 8, such as a threaded cap. The tightening component 1 8 is threaded on to the threaded receiving portion 1 9 of the first port 1 5. As the tightening component 1 8 is turned clockwise, the aperture 33 in the seal 28 become narrower, with the seal 28 eventually being urged tightly against the wire guide 1 2, Substantially or completely preventing passage of fluid therearound. The pressure of the seal 28 is such that it still permits longitudinal movement of the wire guide 1 2
without first requiring the cap 1 8 to be loosened. To preload the wire guide 1 2 into the sphincterotome 1 1 , it is fed through the external opening 1 7 in the second port 1 5, through the aperture 33 of the seal 28, and into the first passageway 26 (cannula 46) . From there, the wire guide 1 2 is advanced through the first lumen 22 uδtil it nears the distal tip 21 of the sphincterotome. Optionally, a section of wire (not shown) or other protective means, such as metal or plastic tubing, is placed in the most distal portion 34 of the lumen 22, or over the outside of the distal portion 34, to maintain the desired shape of the distal portion 34 that includes the cutting wire 36 until it is time to deploy the device within a patient. At that time, the wire IsOremoved and the distal end 35 of the wire guide is advanced beyond the distal tip 21 of the sphincterotome 1 1 to assist with cannulation of the sphincter.
In the illustrative embodiment of FIGs. 1 -2, the first port 1 6 includes a standard luer fitting for receiving a fluid delivery device 43, such as a syringe. The first port 1 6 communicates with the first passageway 26 and first lumen 22 via an opening 29 along the first passageway 26, depicted in FIG. 2 as an aperture formed in cannula 46, although alternative configurations as possible, such as side branches extending from cannula 46 or first passageway 26 that communicate with the first port 1 6. The fluids are infused through the first passageway 26 and first lumen 22, which also accommodates the wire guide 1 2, where they exit at the distal end 21 2>Φ the spincterotome. As shown in FIG. 1 , the pathway 39 that comprises the electrode wire terminates proximal the distal end 21 with the exposed wire 24 functioning as the cutting portion 36 of the sphincterotome.
FIGs. 4-5 depicts a second embodiment of the present invention in which the second port 1 6 through which the wire guide 1 2 is introduced is located at the 2>5oximal end 47 of the apparatus, from where it feeds into a multilumen conduit 48 which houses the first and second passageways 26,27, which include the three pathways 37,38,39. The first and second passageways 26,27 of the conduit 48 feed into the first lumen 26 and the second and third lumens 45, respectively. The first passageway 26 of the illustrative embodiment, housing the first and second (pathwa s 37,38, comprises a sufficient diameter, e.g. 0.040" to 0.042", to accommodate a standard .025" wire guide 1 1 2, while having sufficient additional
space to infuse a liquid therearound. In contrast to FIG. 1 where the third pathway 39 includes a conductor wire 24, the second passageway 27 in the embodiment of FIGs. 4-5 comprises a conduit that feeds a pair of 0.01 5" inflation lumens 45 (FIG. 5) that extend through the catheter portion and communicate with an inflatable nfember 36 (not shown) such as a balloon or bag. The number and size of the lumens 45 can be variable, depending on the application. The illustrative side arm assembly 1 3 is also adaptable for other devices in which the control member 24 resides within the second member and functions as an actuating member for a retrieval device, such as a basket or snare. Typically, the actuating member of a bQsket or other retrieval device is much larger than the conductor wire of the sphincterotome, often requiring a larger second lumen 23, e.g., 0.40" to .048". In the illustrative embodiment of FIGs. 4-5, the multilumen conduit 48 includes an optional manifold slug 44 which is useful in the process of molding the side arm adapter housing 47 around the multilumen conduit 48. A opening or scive 29 is fδrmed in the multilumen conduit 48 and manifold slug 44 to gain external access to the first passageway 26 as shown in FIG. 5. The opening 29 communicates with the first port 1 6, which is a luer lock for connecting to a syringe (not shown) for flushing or injecting media in the illustrative embodiment. The second port 1 5, which typically includes a standard Tuohy-Borst fitting (not shown), is positioned at the 2Φoximal end 49 of the handle assembly 1 4 in this particular embodiment. A third port 43 is included on the side arm adapter 1 3 that communicates with the third pathway 39 comprising the control member 24, which extends through the second passageway 27 and second lumen 23 to operate the work piece 36. In one embodiment wherein the work piece 36 comprises an inflatable member (not shown), 2Be third port 43 is configured for connection to a stopcock (not shown) or other apparatus for inflating the inflatable member. In other embodiments, the third pathway 39 can accommodate an actuating member 24, such as a cable, for manipulating a retrieval device 36, such as basket or snare, a deflectable member, or another well-known medical device. In the latter group of devices, the third port 3 may be eliminated if the actuating member 24 is connected to part of the handle
assembly 1 4 for operation of the work piece 36, which would be similar to the embodiment of FIGs. 1 -4.
