Abstract
The present disclosure relates to a hemodialysis catheter that can monitor intravascular pressure using a MEMS sensor. The hemodialysis catheter comprises a venous lumen, an atrial lumen, and at least one MEMS system sensor. The hemodialysis catheter also comprises a data acquisition and processing system. The hemodialysis catheter can communicate with a monitor system to display pressure data.
Claims15
A hemodialysis catheter comprising:
- an elongate member having a proximal end, a distal end, a first tubular component and a second tubular component;
- wherein the first tubular component and second tubular component extend from the proximal end to the distal end of the elongate member;
- wherein the second tubular component extends a further distance from the proximal end of the elongate member than does the first tubular component;
- a microelectricalmechanical system sensor disposed proximate a distal end of the second tubular component;
- a connector hub at the proximal end of the elongate member;
- and
- at least one access line affixed to the connector hub in communication with at least a portion of the elongate member.

A method of performing hemodialysis comprising:
- inserting a portion of a hemodialysis catheter into the vasculature of a patient;
- wherein the hemodialysis catheter comprises a venous lumen, an atrial lumen, and at least one microelectricalmechanical system sensor near a distal end of the hemodialysis catheter;
- zeroing the microelectricalmechanical system sensor;
- analyzing the microelectricalmechanical system sensor waveform to determine position of the catheter relative to the heart;
- initiating blood flow from the patient, through the atrial lumen, to a dialyzer, through the venous lumen, and into the vasculature of the patient;
- measuring central venous pressure;
- assessing volume status;
- and
- stopping the blood flow from the patient.
