Dialysis catheter including pressure and impedance sensors

Abstract

In examples described herein, a catheter configured to deliver dialysate and extract an effluent fluid from a peritoneal cavity of a patient includes at least two sensors configured and positioned to generate respective signals indicative of one or more parameters related to PD treatment provided to the patient. The sensors can include, for example, a pressure sensor configured to generate a pressure signal indicative of a pressure of a fluid within a lumen of the catheter or external to the catheter and an impedance sensor configured to generate an impedance signal indicative of an impedance of a fluid within the lumen of the catheter or external to the catheter. A parameter related to PD treatment can include, for example, a catheter status or a peritoneal cavity status of the patient.
