Definitions

  • This invention pertains to catheters and more particularly to urethral catheters.
  • Catheter devices are well known in the prior art and have previously been used, for example, for emptying bladders. Catheters are particularly useful for this purpose in conjunction with people who, for example, for reasons of spinal cord injuries, are neurologically unable to empty their bladders.
  • a wide ⁇ spread technique for these individuals to empty their bladders is to insert a catheter through the urethra into the bladder, thereby allowing the urine to drain out of the bladder through the catheter. The catheter is then removed.
  • Figure 1 depicts the use of a typical prior art catheter 11 to empty a bladder 10.
  • catheter 11 is inserted through urethra 13 into bladder 10.
  • One or more orifices 13 at the distal end of catheter 11 serves to accept urine from bladder 10 for removal through fluid channel 12 contained within catheter 11.
  • fluid channel 12 contained within catheter 11.
  • a common result from this failure to provide an indication of how far the catheter has been inserted into the bladder is that the catheter is inserted too deeply into the bladder.
  • Several problems may result from the use of the catheter. For example, if the catheter pushes into the posterior or superior portion of the bladder wall, as shown in Figure 2, the catheter may cause trauma to the bladder, causing irritation and sometimes enough to cause bleeding.
  • Urodyna ic testing involves passing carbon dioxide or water through the catheter into the bladder and monitoring bladder contractions.
  • Prior art catheters are also often used to drain bladder replacements.
  • Patients who must have their bladder removed for any reason i.e. cancer
  • the bladder replacement may be connected to the urethra or may be constructed to drain out of an opening in the abdomen. It is often purposely constructed so it will only drain with catheterization.
  • the patients do not have normal bladder sensation.
  • the intestine has a much thinner wall than the bladder, so there is a risk of pushing a prior art catheter through the bladder replacement, especially shortly after surgery. There is also the problem of incomplete emptying because of placing the catheter too deeply into the bladder replacement.
  • a novel catheter which provides a means for easily and repeatably allowing the user to easily insert the catheter to a predefined distance which is optimal for emptying the bladder. This predefined distance is determined by a physician or nurse during the initial catheterization. Additionally this catheter can be maintained at the correct position, just inside the bladder, for urodynamic testing.
  • this takes the form of an enlarged portion, for example a flange, located between the handle and the insertable portion of the catheter.
  • This flange may be at a fixed distance or slidably adjustable along the length of the catheter. This flange serves to prevent the catheter tip from being inserted into the bladder further than its optimal location.
  • the handle may be made with a considerably larger diameter. This allows it to be more easily grasped by the user than the relatively small diameter of the insertable portion of the catheter. This allows not only easier insertion, but also easier withdrawal of the catheter.
  • an average user can, with little instruction, easily, quickly, and repeatably insert the catheter through the urethra into the bladder to the optimal depth for draining the bladder, and thereby preventing the catheter from being inserted too deeply into the bladder.
  • Figure 1 is a diagram depicting a prior art catheter inserted into a bladder
  • Figure 2 is a diagram depicting a prior art catheter inserted far too deeply into a bladder, thereby causing trauma to the bladder wall;
  • Figure 3 is a longitudinal cross-section of one embodiment of a catheter device constructed in accordance with the teachings of this invention.
  • Figure 4 is a cross-sectional, longitudinal view of one embodiment of a catheter device constructed in accordance with the teachings of this invention shown inserted through the urethra and into the bladder of a female user.
  • FIG 3 is a longitudinal cross section of one embodiment of the catheter device 30 constructed in accordance with the teachings of this invention.
  • catheter device 30 includes insertable catheter portion_33-constructed-much alon the lines of prior art catheters, and including one or more orifices 34 located at its distal end.
  • insertable catheter portion 33 is of limited length, and connected to or integrally formed with the remainder of catheter device 30.
  • the remainder of catheter device 30 includes handle 31 and flange or stop means 32 connected to the proximal end of insertable catheter portion 33.
  • Handle 31 is made to any convenient diameter and length, in order to be easily grasped and manipulated by a user. If desired, handle 31 is integrally formed with flange 32 and insertable catheter portion 33 as a single structure. Alternatively, one or both of flange 32 and insertable catheter portion 33 are removable from handle portion 31, for example by snaps, threads, etc. If desired, each of the components, i.e. handle 31, flange 32, and insertable catheter portion 33 are formed of stainless steel, various plastics, rubber, or silicone.
  • insertable catheter portion 33 is fabricated to have a diameter B within the range of approximately 12 to 18 French, preferably 14 French. (French is the terminology used to describe the circumference of a urinary catheter. French size is equivalent to the circumference of the catheter in millimeters, or 3.14 times the diameter of the catheter in millimeters.) Insertable catheter portion 33 is fabricated to have a length C. In the adult male, length C will range between approximately 18 and 25 cm. In the adult female, length C will range between approximately 4 and 8 cm.
  • Handle 31 is fabricated to have the same diameter or a larger diameter than insertable catheter portion 33.
  • the diameter A of handle 31 is formed in the range of 12 to 36 French, preferably 30 French.
  • handle 31 with a larger diameter than the insertable portion 33 allows handle 31 to be much more easily grasped and manipulated by the user than are prior art catheters, which maintain the diameter of the insertable portion throughout the entire length of the catheter.
  • the length of handle 31 will vary from approximately 3 cm to 6 cm in the male and from approximately 6 cm to 15 cm in the female.
  • catheter device 30 includes flange 32 located between handle 31 and insertable catheter 33.
  • Flange 32 has a thickness E in the range of approximately 0.5 to 1 cm, typically 0.7 cm.
  • Flange 32 also has a diameter D of approximately 1.5 to 3.5 cm, and preferably approximately 2.5 cm.
  • Flange 32 serves as a stop, thereby preventing catheter device 30 from entering into the urethra to a distance greater than C. In this manner, orifice 34 located at the distal end of insertable catheter portion 33 is insured to be located in the optimal portion of the bladder for drainage via catheter, avoiding the problems often encountered with the use of prior art catheters.
  • flange 32 allows insertable catheter portion 33 (having length C) to be inserted through the urethra into the bladder to the point just beyond the bladder neck, thereby allowing complete drainage and preventing damage to the bladder wall.
  • a flange 32 having a diameter D distinct from the diameter A of handle 31 allows the design of both handle 31 and flange 32 to be optimized for their own specific purposes.
  • flange 32 is slidably adjustable along the length of the catheter so as to provide the appropriate length C of insertable catheter portion 33.
  • catheter 30 includes markings in order to provide an indication of a preferred depth of insertion for a particular patient.
  • orifice 34 is connected to a channel running through insertable catheter portion 33, flange 32, and handle 31 to an appropriate exit point in handle 31.
  • handle 31 and flange 32 are fabricated to have the same diameter or, in other words, a single portion of catheter device 30 serves as both handle 31 and flange 32.
  • a diameter is selected which serves as both a useful diameter handle 31 to facilitate grasping and manipulation by the user, and for flange 32 which serves as a stop means defining how deep within the bladder orifice 34 is located.
  • Figure 4 depicts catheter device 30 inserted through urethra 42 into bladder 41 of a female patient.
  • flange 32 has a diameter sufficiently large to serve as a stop at opening 43 of urethra 42, thereby preventing catheter device 30 from being inserted through urethra 42 into bladder 41 too deeply.
  • orifice 34 located at the distal end of insertable catheter portion 33 of catheter device 30 is located at approximately the optimal portion of bladder 41 for drainage of urine, i.e. that portion of bladder 41 just beyond bladder neck 41a.
