“…The weight of the tip (12 g) is intended to prevent catheter displacement when floating in the peritoneal fluid or as a result of bowel loop movement. Although the incidence of malfunction with SLCs is lower when compared to other types of catheters, (14,(16)(17)(18)(19)(20)(21)(22)(23), current prospective studies are limited and there is no record of randomized studies.…”

“…Multiple studies have shown improved function, decreased migration, and longer catheter survival with the SLPDC. [9][10][11][12][13][14] However, drawbacks of the SLPDC include the signi cantly increased diameter of the terminal tungsten cylinder compared to the nominal diameter of the catheter precluding the ability to place it percutaneously through small sheaths, its inability to vary the length of the effective catheter, and its restricted application to a straight catheter instead of a coiled catheter.…”

Purpose Peritoneal dialysis (PD) catheters function best when residing within the retrovesical space of the peritoneal cavity, but they frequently migrate and fail. A novel variable length and conforming PD catheter weighted anchor to prevent migration has been evaluated.Methods Test devices were placed in normal saline for 21 months. The effluent was periodically measured for heavy metals, including tungsten. The water-tight property of the device was also tested separately. Four cadavers were subjected to three-dimensional imaging and maneuvering to evaluate percutaneous insertion, function, stability within the retrovesical space, and percutaneous retrievability in 10 test devices.Results Liquid leakage was low, with a mean absorbance of the test device effluent saline of 0.015. Mean methylene blue absorbance of the test device was significantly lower than the positive control (p-value = 0.01). Leakage of tungsten from devices made with medical grade Silastic tubing was also low, with a mean of 0.362 mg/L in the effluent saline, compared to a background concentration of 0.166 mg/L. Each test device was successfully inserted into the retrovesical space and retrieved percutaneously and remained completely intact following placement and insertion. No test device migrated as shown on axial cone beam CT imaging. Mean flow times and volumes were satisfactory at 3 minutes and 0.92L, respectively, for all test devices. For all catheters, the mean flow rate was 312 cc/min. No significant difference was found between the pre-roll and post-roll mean flow rates of the test devices (p-value = 0.35).Conclusion This PD catheter weighted anchor showed stability, with minimal leakage of tungsten. All test devices were successfully inserted and retrieved percutaneously, with no damage or migration, and mean flow rates were satisfactory. Further investigation is warranted.

“…[8] Revision of PD catheter migration is often unsuccessful, usually resulting in PD catheter replacement. [9] PD catheter malfunction is one of the major barriers to increasing the utilization rate of PD. This study has evaluated multiple variations of a protoype PD catheter device which combines an effective weight effect at the intraperitoneal terminus of the catheter with other features, such as maintaining the same low pro le throughout the PD catheter length.…”
