Japanese study investigates new device for accurate haemodialysis catheter placement

20th Aug 2018

Researchers at Okayama University report in The Journal of Vascular Access the use of a supporting device for accurately placing haemodialysis catheters in dialysis patients. The device was successfully used in a group of 10 patients and, according to the investigators, is expected to become an essential tool in situations where other, catheter-free haemodialysis approaches are not possible.

Toshiaki Ohara (Assistant Professor, Okayama University, Okayama, Japan) and colleagues developed a device which they have found helps to enable accurate tunnelled cuffed catheter (TCC) placement. The researchers’ insertion support device accommodates for individual body shape differences and is expected to decrease the rate of TCC replacements—typically ranging between 8.9% and 56%.

The device was made from expanded polytetrafluoroethylene (ePTFE). It can be described as a bendable ribbon with holes (eyelets) spaced 1cm apart; the holes allow for the making of markings on the patient’s body with a felt-tip pen.
