The retention balloon of the Foley urinary drainage catheter is replaced by a new self-retaining system. This new self-retaining catheter eliminates the problem of residual urine and also of bladder wall irritation caused by continuous contact with a spherical retention balloon; it also does not rely on a stylet for placement. The new system may use an internal control wire that reversibly foreshortens the proximal end of the catheter thus radially displacing longitudinal strips defined in the proximal catheter to form retention wings. Alternatively, a balloon situated between the longitudinal strips is inflated to force open the retention wings once inside the urinary bladder. Radial displacement of the retention wings widens the spaces between the longitudinal strips, these spaces constituting the drainage apertures which permit complete emptying of the urinary bladder, thereby eliminating a source of bladder irritation. The radially displaced retention wings abut the bladder wall in a non-continuous manner thereby reducing the area of bladder-catheter contact and further reducing bladder wall irritation.

An indwelling urinary catheter assembly is disclosed having an indwelling catheter and a sheath enclosing an insertable portion of the indwelling catheter.

An indwelling urinary catheter having a simple structure that can discharge urine easily is disclosed. The indwelling urinary catheter comprises a body that includes an inserted part to be inserted into the bladder, and a non-inserted part that is formed in one body with the inserted part and positioned outside of the bladder, a discharging tube installed inside of the body for discharging the urine, the first fixing member formed inside of the inserted part, and an expander one end of which is fixed to the first fixing member. Typical problems associated with the conventional balloon-shaped fixing member are resolved because the indwelling urinary catheter is fixed in a desirable position by an expanding a part of the body. Also, because the indwelling urinary catheter of the present invention needs no additional fixing devices such as the balloon-shaped fixing device but instead can be fixed by the expander, it has a simple structure and enlarged inner diameter of the discharging tube. Thus urine is discharged from the bladder effectively. Moreover, the indwelling urinary catheter has a long life and can be manufactured economically and quickly due to the simple and effective structure.

A partial-length catheter, or an extendable tube or sleeve member of the catheter, is selectively movable within the prostatic urethra to open a urine drainage passageway through and obstructed portion of the prostatic urethra or to open the external urinary sphincter muscle and thereby discharge urine from the bladder. A control element is manipulated at a position exterior of the urinary canal to selectively move the catheter or the extendable tube or sleeve member, thereby selectively controlling urine discharge. The catheter may also be used to diagnose urinary retention problems caused by a weak bladder or a prostatic obstruction.

The invention provides an improved indwelling urinary catheter of the inflatable type having a unique, low profile device by which to retain the catheter within the bladder, so that urine can be removed therefrom while avoiding obstruction to the descending fetal vertex during the process of labor and delivery. Thus, making it better suited for obstetrical applications. The retaining device consumes less obstructing volume in the bladder than that which would ordinarily be consumed by a conventional Foley-style balloon, whereby both the frequency and severity of fetal vertex obstruction and its resulting increased time of labor, operative delivery and injury to maternal urologic tissue can be reduced. The obstetrical foley retains the tradition Foley-style balloon distal to the improved low-profile laboring balloon for insufflation in the event a surgical delivery by cesarean section is indicated. The traditional balloon with its larger volume allows easy identification of the bladder during surgical delivery. This unique design allows the added advantage of multiple options and uses in a single foley catheter without the need of changing catheters.
