Filed:

Dec 30, 2002

Appl. No.:

10/331949

Inventors:

Rebecca Gottlieb - Culver City CA, US
Rajiv Shah - Rancho Palos Verdes CA, US
Mary M. Morris - Mounds View MN, US
Victor Giron - North Hills CA, US

Bradley J. Enegren - Moorpark CA, US

Assignee:

Medtronic Minimed, Inc. - Northridge CA

International Classification:

A61B 5/00
A61B 5/05
A61M 5/00
A61M 35/00

US Classification:

600300, 600309, 600347, 600365, 604264

Abstract:

A multilumen catheter having tubings extending into lumens within the catheter. The lumens may be used for blood, drugs or other medicants. The lumens may also be used for sensors. The junction element, external to the patient, connects the tubings to the lumens. The tubings, also external to the patient, connect to infusion members, to which one or more infusion systems may be connected to deliver blood, drugs and other medicants to the patient. A sensor having a sensing element may extend through the sensor lumen and be positioned internal to the patient for physiological parameter sensing. An external portion of the sensor may be connected to associated electronics to provide automatic monitoring of the physiological parameters and automatic delivery and control of the infusants. Also, a central line catheter for delivering fluids directly into a main artery or vein near the heart, which contains a first lumen to deliver a fluid through the central line catheter and a second lumen containing a sensor capable indicating a characteristic level in blood. The first lumen delivers the fluid downstream of the sensor to prevent any interference between the fluid delivery and the sensor readings.

The first lumen delivers the fluid downstream of the sensor to prevent any interference between the fluid delivery and the sensor readings. In other versions, the central line catheter can have additional lumens for additional purposes. In addition, the central line catheter can further include a flush sleeve to remove debris around the sensor.
