What is a double lumen catheter?
Double lumen catheters are sometimes referred to as double-D lumen catheters in reference to the shape of each lumen in some designs, i.e., two semicircles. Many triple lumen catheters also have a design that is symmetrical, with the cross-section looking like a peace symbol.
What is the difference between a double lumen and a triple lumen?
If you place the central line for volume resuscitation or simple IV access, the double lumen catheter may be a better choice than a 7fr triple lumen. These catheters may be a larger french so each lumen is larger allowing for faster flow rates. See Poiseuille’s Law.
What is the difference between 7-fr and French triple-lumen catheters?
For instance, 7-Fr triple-lumen catheters have narrow lumens, long lengths, and high resistance to flow, restricting the rate of blood administration and creating increased shear force on blood cells that can damage them. Nine French triple-lumen catheters have larger lumens and shorter lengths and are satisfactory for blood administration.

How long can a dialysis catheter stay in?
Non-cuffed tunneled catheters are used for emergencies and for short periods (up to 3 weeks). Tunneled cuffed catheters, a type recommended by the NKF for temporary access, can be used for longer than 3 weeks when: An AV fistula or graft has been placed but is not yet ready for use.
How long can you live on dialysis?
Life expectancy on dialysis can vary depending on your other medical conditions and how well you follow your treatment plan. Average life expectancy on dialysis is 5-10 years, however, many patients have lived well on dialysis for 20 or even 30 years.
How long does it take to insert a catheter for dialysis?
Using image-guidance, the catheter will be manipulated to the vein. You may feel some additional pressure as the catheter is put in place. The procedure usually takes between 30 and 40 minutes.
What is a triple lumen PICC line?
PICC lines are inserted by certified PICC specialists, who use ultrasound and X-ray images to ensure that the line is in the correct spot. PICC lines can have 1-3 lumens, which allow medications to be attached and flow through the line. Additionally, blood draws for lab purposes can also be extracted from the line.
What size gauge is a PICC?
The catheter size for PICC lines is generally measured in French gauge, and may range from 2–6.
What is a triple lumen central line?
A double lumen catheter has 2 lumens while a triple lumen catheter has 3. Multi-lumen catheters allow us to run several different infusion with only one access site (Image 2). Multi-lumen catheters are often inserted through a short central line with a wider inner diameter.
What is the purple lumen for on a PICC line?
The end of each lumen has a hub which is coloured. Double lumen PICCs may have a BROWN or PURPLE hub and a WHITE hub. Generally the BROWN or PURPLE lumen is used to take blood samples and for giving blood products. The WHITE lumen is used for medications and IV fluids.
Lumen Design
Multi-lumen catheters often feature two or three lumens, although four and five-lumen designs are also common. In some situations, it is even possible to have more than five lumens.
Material Considerations for Multi-Lumen Catheters
The materials used in the design of a multi-lumen catheter will impact the performance of the device. For example, in multi-lumen catheters that feature multiple materials, the performance of the device will be impacted by each of the materials used.
Functional and Mechanical Considerations for Multi-Lumen Catheters

Speak to an Engineer
Multi-lumen catheters can be challenging to fabricate, highlighting the importance of an effective and structured design process. Excellent knowledge of materials is also required, in addition to design for manufacture and design for assembly expertise.
What is a Trifusion-Triple lumen catheter?
A trifusion triple lumen catheter is a central venous catheter made of polyurethane adapted from a Hickman catheter design. The catheter is a tunneled central venous catheter much like the Hickman catheter and is used for and considered a long-term catheter. The main difference between a trifusion catheter and a Hickman or broviac catheter or other similar catheters is the three lumen design of the catheter. This allows for the catheter to be used for various reasons simultaneously ie. for collecting blood samples and administering drugs. The catheter enters the vein near the base of the neck (Most commonly the internal jugular vein) where it travels through the central veins with one end of the catheter is placed in a large vessel near your heart (Superior vena cava/right atrial junction) and the other end tunneled under the sin exiting below the collar bone on the chest.

Why is a catheter cuff sutured in place?
The catheter is initially sutured in place to allow the cuff to have tissue ingrowth.
Where is the catheter placed in the heart?
Most commonly the catheter is placed into the internal jugular vein on the right just above the clavicle where it passes through the subclavian/brachiocephalic vein to enter the superior vena cava with the tip of the catheter opening at the superior vena cava (SVC) right above the right atrium of heart. The catheter can also be inserted into directly into axillary-subclavian vein percutaneously as opposed to the more common jugular vein access. If the catheter enters medially, there is a chance of catheter compression between first rib and clavicle, this is referred to as pinch off syndrome.
