iLet Infusion Set Options:
Living with an insulin delivery system means that small equipment choices can make a big difference in everyday comfort and confidence. If you use the iLet Bionic Pancreas, understanding your iLet infusion set options can help you choose a setup that fits your routine and your healthcare provider’s recommendations.
The infusion set is the part that connects the iLet system to your body and delivers insulin through the cannula. Beta Bionics currently lists compatible infusion-set options including Inset™ and Contact™ Detach, with differences in cannula material, length, and how long the set is intended to be used.
At Alfa Healthcare Supply Inc., we understand that ordering diabetes supplies is about more than finding a product. You want the right supply, clear information, and dependable service. This guide explains the important iLet infusion set options in simple language so you can discuss the best choice with your healthcare professional.
What is an iLet Infusion Set?
An infusion set is a small disposable system used to deliver insulin from an insulin pump to the body. It generally includes the cannula or needle, adhesive base, connector, and tubing.
For the iLet Bionic Pancreas, the infusion set works as part of the insulin-delivery system. The iLet automatically adjusts insulin delivery based on compatible CGM information, but the physical infusion set still needs to be properly inserted, connected, and functioning.
Beta Bionics warns that users should receive appropriate training and follow the iLet User Guide. Incorrect use can result in too much or too little insulin delivery.
That is why understanding your iLet infusion set options is important before ordering or changing your supplies.
What are the Main iLet Infusion Set Options?
When comparing iLet infusion set options, two important names to know are:
- Inset™
- Contact™ Detach
Beta Bionics identifies compatible infusion sets and provides dedicated instructions and support resources for both options.
The options are not exactly the same. They use different cannula materials and may have different available lengths and intended wear periods.
1. Inset™ Infusion Set
Inset is a Teflon-cannula infusion set. The iLet User Guide lists compatible Inset configurations with 6 mm and 9 mm cannula lengths, with an intended duration of approximately 2 to 3 days.
The Inset design also allows temporary disconnection from the pump without necessarily removing the entire infusion set. Manufacturer instructions describe disconnecting the tubing from the cannula housing and reconnecting it later.
For some users, this can make the Inset option convenient for everyday routines.
2. Contact™ Detach Infusion Set
Contact Detach uses a steel cannula. The iLet User Guide lists 6 mm and 8 mm cannula lengths, with an intended duration of approximately 1 to 2 days.
The steel-cannula design provides another option for people who may have particular infusion-set needs. Your healthcare provider can help determine whether this style is appropriate for you.

Why Cannula Material Matters
One of the most important differences between these iLet infusion set options is the cannula material.
Teflon Cannula
Inset uses a soft Teflon cannula. A soft cannula sits under the skin after insertion while the introducer needle is removed.
Some people prefer soft cannulas because of their feel and flexibility.
Steel Cannula
Contact Detach uses a steel cannula. Steel infusion sets can provide a different experience compared with soft-cannula sets.
Beta Bionics’ healthcare-provider guide discusses steel infusion sets as an option that may be considered for people with a history of infusion-set failures or other circumstances where reliable insulin delivery is especially important.
However, this does not mean one style is universally better. Your healthcare provider should help you decide which option is appropriate for your individual situation.
How Do You Choose Between iLet Infusion Set Options?
Choosing among iLet infusion set options should not be based only on price or appearance. Think about your daily routine, previous infusion-set experience, skin comfort, cannula requirements, and your healthcare provider’s recommendation.
Consider Your Previous Experience
If you have previously used an insulin pump, you may already know whether you prefer a soft or steel cannula.
If you are new to pump therapy, your diabetes care team can help you understand the differences.
Consider Wear Duration
Inset and Contact Detach have different listed durations in the iLet User Guide. Inset is listed for 2–3 days, while Contact Detach is listed for 1–2 days.
Always follow the manufacturer’s instructions for changing your particular infusion set.
Consider Comfort
Everyone’s skin and body are different. An infusion set that feels comfortable for one person may not feel the same for someone else.
Pay attention to irritation, discomfort, adhesive problems, or repeated site issues, and discuss them with your healthcare professional.
Consider Your Lifestyle
Think about exercise, work, sleep, travel, clothing, and other daily activities.
The right infusion set should fit into your normal routine rather than making diabetes management unnecessarily difficult.
iLet Infusion Set Options and Site Selection
Infusion-set placement matters because insulin delivery depends on a functioning infusion site.
Your healthcare professional should teach you where and how to place your infusion set. Follow the instructions supplied with your particular product.
It is also important to pay attention to your CGM location. Beta Bionics warns not to insert an insulin infusion set within 3 inches of the CGM sensor, because insulin delivery near the sensor can affect sensor accuracy.
Avoid inserting an infusion set into an area that is irritated, damaged, scarred, or otherwise unsuitable according to your healthcare provider’s instructions.
Signs Your Infusion Set May Not Be Working Properly
Knowing the iLet infusion set options is only part of safe pump use. You should also know when an infusion site may have a problem.
According to Beta Bionics, possible signs of infusion-site failure include:
- Glucose levels continuing to rise despite insulin delivery
- Glucose remaining unusually high
- A kinked or dislodged infusion set
- Insulin leaking around the site
- A wet area or noticeable insulin odor
- Problems with tubing or connections
Beta Bionics recommends checking the infusion set, tubing, and connections regularly for leaks, air bubbles, or kinks because these issues can restrict or stop insulin delivery.
If you suspect your infusion set is not working, follow your prescribed troubleshooting procedure and contact your healthcare team when appropriate.
Changing an iLet Infusion Set
Changing an infusion set should always be done according to the instructions for the specific product.
The iLet Supply Change Guide explains that users select the appropriate cannula type and length during the iLet setup process before filling the cannula.
The process generally involves:
- Preparing the new infusion set.
- Preparing the insertion site.
- Inserting the infusion set according to the manufacturer’s instructions.
- Connecting the tubing correctly.
- Selecting the correct cannula type and length on the iLet.
- Filling the cannula as instructed.
- Confirming that insulin delivery has resumed.
Never improvise the filling or insertion process. The manufacturer specifically provides instructions because incorrect handling can result in unintended insulin delivery.
Why Having Extra iLet Infusion Sets Is Important
Diabetes supplies can sometimes be damaged, lost, disconnected, or affected by an unexpected site problem.
For this reason, keeping backup supplies available is a smart part of preparation.
Beta Bionics’ safety information recommends carrying insulin infusion sets as part of an emergency kit and lists a minimum of two infusion sets among the supplies to carry.
Having backup supplies can be especially helpful when traveling, working long hours, exercising, or spending time away from home.
Buying iLet Infusion Set Options
When ordering iLet infusion set options, check the product name carefully.
Do not assume that every infusion set designed for another insulin pump will work with the iLet. Compatibility is important.
Beta Bionics specifically identifies compatible infusion sets for the iLet and provides manufacturer resources for Inset and Contact Detach.
At Alfa Healthcare Supply Inc., customers can explore diabetes and durable medical equipment supplies while getting help understanding product information before placing an order.
Final Thoughts on iLet Infusion Set Options
Understanding your iLet infusion set options can make routine diabetes supply decisions easier. The two major options to know are Inset, which uses a Teflon cannula, and Contact Detach, which uses a steel cannula. They also differ in available cannula lengths and intended wear duration.
The best choice depends on your individual needs, comfort, lifestyle, and healthcare provider’s recommendations. Always use infusion sets specifically identified as compatible with your iLet system and follow the manufacturer’s instructions.
