A catheter left inside the body, either temporarily or permanently, may be referred to as an indwelling catheter. A permanently inserted catheter may be referred to as a permcath.

New device for accurately placing hemodialysis catheters on kidney patients

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