A Foley catheter can also be used to ripen the cervix during induction of labor. When used for this purpose, the procedure is called extra-amniotic saline infusion . [ 9 ] In this procedure, the balloon is inserted behind the cervical wall and inflated, for example with 30-80 mL of saline. [ 9 ]
Cervical dilation may be induced mechanically by placing devices inside the cervix that will expand while in place. A balloon catheter may be used. Other products include osmotic dilators , such as laminaria stick (made of dried seaweed) or synthetic hygroscopic materials, which expand when placed in a moist environment.
Extra-amniotic saline infusion (EASI), [14] in which a Foley catheter is inserted into the cervix and the distal portion expanded to dilate it and to release prostaglandins. Cook Medical Double Balloon known as the Cervical Ripening Balloon with Stylet for assisted placement is approved by the FDA in the United States.
A balloon catheter is a type of "soft" catheter with an inflatable "balloon" at its tip which is used during a catheterization procedure to enlarge a narrow opening or passage within the body. The deflated balloon catheter is positioned, then inflated to perform the necessary procedure, and deflated again in order to be removed.
The cervix consists of two parts; the upper part lies in the pelvic/abdominal cavity and the lower part is intravaginal. [1] Cervical effacement or cervical ripening refers to the thinning and shortening of the cervix. This process occurs during labor to prepare the cervix for dilation to allow the fetus to pass through the vagina. While this ...
Asherman's syndrome (AS) is an acquired uterine condition that occurs when scar tissue forms inside the uterus and/or the cervix. [1] It is characterized by variable scarring inside the uterine cavity, where in many cases the front and back walls of the uterus stick to one another.
Hegar dilators are used to induce cervical dilation in order to gain entry to the interior of the uterus. During the process of dilation, the cervix may have to be stabilized with a tenaculum , and then the dilators are slowly entered into the cervical canal with a lubricant, starting with a thin, low Hegar number rod and progressing gradually ...
Diagram of a Foley catheter. Foley first described the use of a self-retaining balloon catheter in 1929, to be used to achieve hemostasis after cystoscopic prostatectomy. [2] He worked on development of this design for use as an indwelling urinary catheter, to provide continuous drainage of the bladder, in the 1930s.
