Catheter assemblies of the invention are especially useful for sterile handling of suction catheters but the new assemblies may be utilized with urethral catheters, Foley catheters or any other form of tubes or catheters known to the surgical and medical arts which require sterile handling for installation in a patient.

2. Description of the Prior Art In the use of suction catheters, urethral catheters and similar medico-surgical tubes, it is necessary to preserve the sterility of that portion of the catheter which enters the body of a patient in order to prevent the patient from becoming infected by the insertion of the catheter. This presents difficulties to the surgeon or other person performing the catheter installation. For example, if it is necessary to catheterize a patient during a surgical operation, the surgeons hands or gloves will normally be soiled by blood or other materials which would come in contact with the walls of the catheter and be carried into the patients body if the surgeon were to directly contact the catheter during the installation with such soiled gloves. As a result, catheter installation under such circumstances is frequently performed by another person wearing a sterile pair of surgical gloves. As a matter of fact, this occurs so frequently that manufacturers of catheters make and sell so-called tray packages which enclose in sterile condition a catheter along with a pair of surgical gloves to be used in performing the installation of the catheter. Of course, not only does this add to the cost of catheterization of a patient, but the procedure consumes more time than is desirable. The magnitude of the problem can be understood if one realizes that a postoperative patient may need to be suctioned every minutes and at progressively longer intervals as his condition improves. Couple this with the fact that it is the current trend for hospitals to use suction catheters for a single use only and that as many as 400 suction catheters could be used on one patient within a 2-week period and it becomes apparent great saving in time can be made by eliminating the need for sterile gloves when suction catheters are installed.

It' has been proposed to enclose catheters in protective sheaths which are slit longitudinally so that the catheter can be manipulated into the body of a patient while its sterility is protected by the sheath. Catheter assemblies of this type are disclosed, for example, in US. Pat. Nos. 3,262,448 and 3,559,643. However, the concept of use of a protective sheath in the handling of catheters as employed in the prior art has been of relatively limited scope. Thus, in order to use the prior known catheter assemblies involving the protective sheath, the devices have required means other than the sheath itself to push the catheter for installation in the patient while preserving its sterility. Furthermore, use

of the prior known catheter assemblies have essentially been limited to a two-hand type of operation.

OBJECTS A principal object of this invention is the provision of new forms of sterile handling catheter assemblies. Further objects include the provision of:

l. Sterile handling catheter assemblies in which the catheter is carried in a protective sheath of unique construction which permits the sheath to be used as a means by which the catheter is advanced for installation in a patient.

2. Improved sterile handling catheter assemblies which are capable of being installed in a patient with a one-hand technique.

Other objects and further scope of applicability of the present invention will become apparent from the detailed description given hereinafter; it should be understood, however, that the detailed description, while indicating preferred embodiments of the invention, is given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

SUMMARY OF THE INVENTION The stated objects are accomplished according to the present invention by provision of sterile handling catheter assemblies which comprise a catheter, and a pro.- tective sheath formed of flexible plastic material enveloping at least the proximal end and central body portions of the catheter. The protective sheath has a longitudinal slit extending the entire length thereof, a pair of ribs extend radially from the sheath and run the full length thereof adjacent and parallel to the slit. These ribs serve as barrier members above the slit to preserve the sterility of the edges of the slit while the protective sheath is manipulated by a surgeon or other person and used as the means to advance the catheter for its installation in a patient. In one embodiment of the new catheter assemblies, the sheath is shorter in length than the catheter so that the distal end portion of the catheter remains uncovered by the sheath. In another embodiment, the sheath is longer than the catheter so that even the distal end portion is covered and the sheath extends beyond the distal end, e.g., about 1-3 cm.

Advantageously, both the catheter and the protective sheath are formed by extrusion from flexible waterproof non-fibrous thermoplastic. material. In such an extrusion, the ribs which constitute the barrier members for the slit are formed integrally with the remainder of the protective sheath. Although the longitudinal slit in the sheath can be formed by cutting, it is advanta- BRIEF DESCRIPTION OF THE DRAWINGS A more complete understanding of the new catheter assemblies of the invention and their methods of use may had by reference to the accompanying drawings in which: 7

DESCRIPTION OF PREFERRED EMBODIMENTS Referring in detail to the drawings, a catheter assembly of the invention 2 comprises a catheter 4 and a protective sheath 6. The catheter has a distal end portion 8, a proximal end portion 10 and a central body portion 12 which connects the distal end portion 8 to the proximal end portion 10. The protectivesheath 6 formed of flexible plastic material is shorter in length than the catheter 4 so that the distal end 14 of the sheath terminates proximally of the tip 16 of the catheter leaving the distal end portion 8 of the catheter uncovered. The remainder of the catheter comprising the central body and proximal end portions is enveloped by the protective sheath.

The sheath 6 has a longitudinal slit 18 which extends the entire length of the sheath. A first rib 20 runs the .full length of the sheath adjacent one side of the slit and, as can be seen in detail in FIG. 5, the rib 20 extends radially outwardly from the sheath 6. A second rib 22 which also runs the full length of the sheath adjacent the other side of the slit 18 extends radially outwardly from the sheath 6 substantially the same distance as the first rib 20.

With reference to FIG. 5, it can be seen that the ribs 20 and 22 create a pair of parallel barrier members above the slit l8 preventing objects, such as the finger 24 of a surgeon, from contacting the edges of the slit during manipulation of the catheter assembly in installation of the catheter in a patient. Hence, the pair of ribs 20 and 22 preserve the sterility of the slit edges 26 and 28 and thereby insure the sterility of the catheter when these edges contact the catheter as the protective sheath 6 is stripped from the catheter 4 during insertion of the catheter in a patient (see FIGS. 2 and 6).

The catheter assemblies of the invention require only one-hand manipulation to accomplish sterile installation of the catheter into a patient. The method of use of the new catheter assemblies can be understood by reference to FIGS. 1 and 2 which illustrate the installation of a suction catheter into a patient by way of a tracheostomy tube 30. With reference to FIG. 1, the protective sheath 6 of the suction catheter assembly 2 is grasped between the thumb 36 and index'finger 38 of j a short distance further along the protective sheath away from the junction between the catheter 4 and the parting in the sheath 6 and gently pushes the catheter assembly toward the patient so that a further section of the catheter enters the tracheostomy tube 30. As the catheter enters the tube, a further section of the sheath will part along the slit 18 and the portion of the sheath 6 which separates from the catheter 4 will slide down the outside and away from the catheter as illustrated in FIG. 2. This procedure is repeated a sufficient number of times so that the catheter advances into the patient to the distance required for the particular procedure being performed. The suction catheter having been joined by way of the vacuum controller 40 to a suction source, the suction catheter can be operated by manipulation of the vacuum controller 40 in the customary manner. It will be understood from this'description of use and by reference to the accompanying FIGS. 1 and 2 that during the manipulation of the catheter assembly for installation of the catheter in the patient, the catheter never comes in contact with any part of the hand 34 of the surgeon. Furthermore, no part of the protective sheath which comes in contact with the fingers or other portion of the surgeons hand will make contact with the catheter. The lumen of the protective sheath 6 is sterile and remains so throughout manipulation of the catheter assembly. The same is true of the edges 26 and 28 of the slit 18 because, as can be seen by reference to FIG. 5, the ribs 20 and 22 prevent any contact by the fingers or other portions of the surgeons hand so that sterility of the slit edges is maintained. This in turn pre serves the sterility of the catheter 4.

Details of construction of the proximal end portion of the catheter assembly illustrated at FIG. 1 are shown in FIG. 4'. The vacuum controller 40, which may be of the form shown and described in U.S. Pat. No. 3,610,242 or of any other suitable structure, is joined to the proximal end 10 of the catheter by a short section of tubing 42 which is cemented at one end to the inlet port 44 of the vacuum controller 40. The tube section 42 has an inside diameter approximately the same size as the outside diameter of the catheter and the proximal end of the catheter is inserted in the tube section 42 and cemented therein.

In the embodiment of the new catheter assemblies shown in FIG. 9, the assembly 60 comprises a catheter 62, a protective sheath 64 and the vacuum controller 66. The sheath 64 is longer than the catheter 62 so that the free end 68 of the sheath extends about I to 3 cm. beyond the distal end 70 of the catheter. The sheath 64 has a longitudinal slit 72 extending the full length thereof and adjacent ribs 74 and 76 as in the case of the embodiments described in connection with FIGS. 1-8.

The use of a catheter assembly as shown in FIG. 9 begins as a two-hand operation. As seen in FIG. 10, the free-end 68 of the sheath 64 with the slit 72 on top is grasped by the surgeon or other operator between thumb 78 and finger 80. Simultaneously, the sheath 64 is grasped near the catheter tip 70 in the other hand between thumb 82 and finger 84. With the finger 86 acting as a support below the catheter tip 70, the sheath end 68 is moved downward by thumb 78 and finger 80. This motion will bend the sheath over the tip 70 of the catheter and the slit 72 will open leaving the catheter tip 70 exposed as shown in FIG. 11. From then on, the installation of the catheter 62 into the patient will be essentially a one-hand procedure as described previously in connection with the embodiment of FIGS. l-8.

Different sizes of catheters are required for a variety of reasons, e.g., different sizes of patients, different medical or surgical procedures orthe like. In the preferred embodiments of catheter assemblies of the invention, each size of catheter will have a protective sheath of the most advantageous size for the particular size catheter with which it will be assembled. Preferably, the catheter sheath will be just slightly larger in inside diameter than the outside diameter of the catheter, e.g., the ID of the protective sheath 6 will be about 0.1 to 1 mm. larger than the OD. of the catheter 4. The wall thickness of the plastic sheath will depend, in part, upon the nature and type of material of which the plastic sheath is formed. Thus, with more rigid material, a thinner wall thickness for the sheath 6 is preferred. The sheath can be formed of any suitable flexible material including polyolefins, e.g., polyethylene or polypropylene; nylon; acrylic resins; etc., although polyvinyl chloride is preferred because this class material offers a wide range of selection and control in flexibility and strength properties making it possible to construct catheter assemblies of a wide range of sizes and shapes from a single type of material. The wall thickness of the plastic sheath advantageously will be between about 0.2 to 1 mm.

The ribs 20 and 22 which extend radially from the tubular cross-section of the plastic sheath may be varied in configuration. A preferred shape is triangular with the base formed integral with the shape per se and a rounded apex. Other shapes, however, are possible including semi-circular, rectangular, square crosssections or the like. Advantageously, the ribs will protrude between about 0.5 and 5 mm. and particularly 1 to 3 mm. above the outer surface of the protective sheath and the distance between the central axes of the ribs will be between about 2 to mm. and particularly 3 to 5 mm.

When plastic sheaths for the catheter assemblies of the invention are constructed and sized as described above, they will be relatively free to slide longitudinally along the catheters which are enclosed within the sheath. It is preferable, therefore, to arrange some means at the proximal end of the sheath to restrain the sheath from sliding along the catheter. This can be done in a variety of ways. For example, the sheath may be cemented or clamped at its proximal end about the encircled catheter. However, the surgeon or other user of the device may wish to completely separate the sheath from the catheter upon completion of the insertion procedure. Accordingly, a sheath restraining arrangement which does not permanently connect the sheath to the catheter is advantageous. An arrangement of this type is illustrated in FIG. 4. The section of connector tubing 42 is of slightly larger outside diameter than the inside diameter of the sheath 6. Accordingly, when the proximal end 46 of the sheath surrounds the connector tube section 42 there will be sufficient frictional engagement between these two parts 42 and 46 to restrain movement of the sheath 6 along the catheter 4.

In certain types of operations and for other considerations, it may be desirable not to remove the protective sheath from the catheter upon completion of the insertion procedure, but allow it to remain in a draped condition as shown in FIG. 2 until the catheter is removed from the patient. Further, when the catheter is removed, it may also be desirable to return the catheter back into the sheath, e.g., to provide a means for sanitary handling of the catheter by preventing the soiled outer surface of the catheter to come into contact with objects which might be contaminated by the mucus or other soiling material upon the catheter. For this purpose, the catheter assemblies of the invention may be provided with a movable slide 48 which can be used for encasing the used catheter within the protective sheath as it is withdrawn. In such a situation, the catheter and sheath will be separated from each other back as far as the catheter had been inserted into the patient. The slide member 48 would be moved distally on the sheath to this point. By holding the slide 48 in one hand and grasping the assembly in the other hand at some more proximal position, e.g., by the attached vacuum controller 40, the slide 48 may be moved towards the distal end of the assembly using a back and forth twisting motion. This forces the catheter back within the sheath as the catheter is simultaneously extracted from the patient. The slide member 48 is a short section of tubing, e.g., extruded plastic tubing,,having an ID. just slightly larger than the CD. of the sheath 6.

In the embodiment of the catheter assembly shown in FIG. 5, the two edges 26 and 28 of the slit l8 abut one another. An alternative arrangement is shown in FIG. 7. Here, one edge 50 of the slit overlaps the other edge 52. A construction of this type for the sheath 6a can easilybe obtained in forming the protective sheath by plastic extrusion by shaping the extrusion die to create a thin lip or ledge on the edge 52 which will underlay the opposing edge 50 of the slit 18a.

DISCUSSION OF DETAILS The catheter which comprises the assemblies of the invention may be manufactured to professional specifications and may be produced in varying degrees of flex ibility or rigidity by varying the formulation of the plastic material from which the tubes are extruded. They should be water-proof, flexible over a relatively wide range of temperatures, resistant to attack by body fluids, capable of being sterilized, such as exposure to ethylene oxide or gamma radiation, and preferably produced by extrusion at high speed in order to be relatively low in cost. There are a variety of plastic materials capable of providing these requirements for the production of catheter assemblies of the invention. Advantageously, both the catheters and the protective sheaths will be formed of non-fibrous plastic material and plasticized polyvinyl chloride is preferred. A particular useful material of this type can be formulated to have an extrusion temperature of about 3253 75F. However,

the invention is contemplated for use in connection with any plastic or elastomeric material known or found to be useful in the formation of disposable catheters, e.g., polyethylene, polypropylene, natural rubber,

synthetic rubber,etc.

The catheters of the new assemblies may be constructed with any special features which are known to be useful with medico-surgical tubes or which may be required for particular procedures in which the catheters are to be employed. These may include a nonsparking feature (see U.S. Pat. No. 3,007,132), x-ray markings (see U.S. Pat. No. 3,605,750) or a frosted surface to reduce friction in contact with other plastic aging material is available for such purposes in which the new catheter assemblies may be contained for extended periods of time in sterile condition immediately available to the surgeon or other user at the location where the catheter is to be used with a patient. Once enclosed in such package, the catheter assembly may be rendered sterile by the use of known sterilization methods, e.g., exposure to ethylene oxide or gamma radiation.

CONCLUSION The invention as described herein provides a means for removing a catheter from a sterile peel-back package and preserving the sterility of the catheter while it is being inserted into a patient, such as through the nose, mouth, urethra, an endotracheal tube,'a tracheostomy tube, a body incision or the like. This is accomplished without the person making the catheter installation needing to wear sterile gloves. When the catheter is introduced into a patient, the distal portion of the catheter, which extends out of the unique protective sheath, is entered into the orifice through which the catheter is to pass. With only one hand, the surgeon or the protective sheath to advance the catheter into required position in the patient. The protective sheath being of such construction that complete sterility of the catheter is maintained during such manipulation, moves out of the way as the catheter is advanced and creates no discomfort or trauma to the patient. Hence, the invention provides new sterile handling catheter assemblies of a single-use, disposable type which can be utilized with maximum efficiency in any required surgical or other medical procedure.
