  • Divided tip urinary catheter with balloon inflation generated method of urine drainage
    Patent number: 11253682
    Abstract: The present invention discloses a urinary catheter that utilizes balloons to generate a method of urine drainage. The disclosed invention does not implement a traditional drainage port and avoids an exposed catheter tip. Rather, this invention consists of a multi-lumen shaft with a divided tip that generates a horizontal aperture for urine drainage when separated. The invention utilizes retention members that can take the form of multiple expandable balloons or a singular, expandable, central balloon. The balloon element can consists of balloons that are attached separately to each divided tip or one balloon shared with adjacent divided tips so that when the balloon element expands, a communication channel is revealed between the bladder and the central lumen of the shaft, ultimately generating a method of urine drainage.
