The materials used in the design of a multi-lumen catheter will impact the performance of the device. Material Considerations for Multi-Lumen Catheters For example, percutaneous transluminal coronary angioplasty catheters typically have lumens of varying sizes and shapes. However, there is no set design for the lumens inside the catheter, as it is possible to size and shape the lumens based on the requirements of the catheter and what it will be used for. Both double and triple lumen catheters are often used for peripherally inserted central catheters. Many triple lumen catheters also have a design that is symmetrical, with the cross-section looking like a peace symbol. For example, a triple-lumen catheter could have one large-diameter lumen and two with smaller diameters.ĭouble 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. It is also possible to design lumens with various sizes and shapes within the same catheter. In some situations, it is even possible to have more than five lumens. Multi-lumen catheters often feature two or three lumens, although four and five-lumen designs are also common. To speak to one of our engineers about your idea for a new multi-lumen catheter device, please get in touch by completing the form below. Instead, each lumen has its own exit point, allowing the treatment to pass through one of the lumens and out of its exit point into the bloodstream Those capabilities include infusing drugs while monitoring flow rate, as well as flushing, cooling, heating, and aspiration.Ī crucial benefit of multi-lumen catheter design is that treatments inserted into the lumens do not mix inside the catheter. However, multi-lumen catheters also have other capabilities. This can include using the separate lumens to administer different treatments. However, the multi-lumen design allows more than one activity to take place during the same procedure. As it is a single catheter, there is only one entry point. In simple terms, a multi-lumen catheter is a single catheter with multiple internal channels or lumens. They can also be designed with a wide range of performance characteristics.įurthermore, advances in the design of catheter devices are opening up new opportunities and making it possible to create new multi-lumen catheter products that will improve the treatment and diagnosis of patients with various complex conditions. You will probably find, however, that someone in the hospital has already obtained this information.Multi-lumen catheters are used for several different applications, including highly complicated procedures. They are usually very accommodating and will supply educational materials to the staff. You merely have to contact the representative who sells them to the hospital. The manufacturers also have a lot of information about the lines that your hospital purchases from them. You might contact your central supply people or the personnel who insert these PICC lines and ask if they have any information about them that they can share with you. It has information about the catheter in it. This booklet is usually placed in the chart at the time of insertion (at least that's where we put it). There is also a booklet that accompanies each PICC insertion kit. Most PICC lines have one lumen that is slightly larger than the other. The minute any infused solution exits the PICC it enters the turbulent blood flow of the superior vena cava and is instantaneously mixed with the incoming blood flow going into the right atrium of the heart and is hemodiluted. The turbulence of the blood in that anatomical area makes the idea of any solutions getting intermingled moot. This can be confirmed by looking at the x-ray report because the placement of the catheter tip should have been confirmed by x-ray. Usually, it is in the superior vena cava of the heart. The answer to the question at hand ultimately lies in where the tip of the PICC line rests. One of the reasons for inserting a dual lumen PICC is for the purpose of infusing two different solutions (including a blood and blood products) through each line at the same time.
