ABSTRACT:
A catheter assembly including a foldable internal bolster. According to one embodiment, the catheter assembly includes a catheter, a first flexible filament and a second flexible filament. The catheter includes a tubular body and a pair of flexible legs. The tubular body is a generally cylindrical member shaped to include a proximal end, a distal end, a longitudinal lumen, a pair of external notches, a first bore extending from the proximal end to one of the notches, and a second bore extending from the proximal end to the other of the notches. Each of the flexible legs has a fixed end and a free end, the fixed end being integrally formed on the distal end of the tubular body. One end of the first filament is fixed to one of the flexible legs, and the opposite end of the first filament is slidably inserted up through the first bore. One end of the second filament is fixed to the other of the flexible legs, and the opposite end of the second filament is slidably inserted up through the second bore. Consequently, by pulling the filaments up through their respective bores, the free ends of the legs may be drawn towards the tubular body to form a pair of loops suitable for use as an internal bolster.
