Our Values

Embody Quality

Build Partnerships

Serve the Greater Good

Earn Trust

Take Ownership

“Your values create your internal compass that can navigate how you make decisions in your life. If you compromise your core values, you go nowhere.”
- Roy T. Bennett
Quality is our #1 goal in manufacturing. It is essential for safe devices and consistent business.
Strong partnerships are built on trust. We believe trust is implicitly granted at the beginning of a relationship and then strengthened through good partnership. We strive to always be strengthening the trust we share with customers, vendors, and team members.
Our business is built on strong partnerships. We join forces with our customers, vendors, and team members to achieve common goals. We are not driven by individual transactions.
Creativity will help propel us into the future.  Without creativity a business will eventually fall behind competitors and stagnate.  Our wide-ranging experience and penchant for trying new things will enable us to develop creative, innovative, and technologically superior solutions.
Greater Good
The world is bigger than us and the moment we live in. We want to be a valued member of the community. Our good fortune is used to pay it forward to a world that needs positive influence.


What is mis?

Midwest Interventional Systems (MIS) is a contract design and development and contract manufacturer for minimally invasive based delivery systems. We design, develop, and manufacture custom medical device solutions.

Where is MIS located?

MIS is located in the heart of Medical Alley in Maple Grove, MN.

HOW does MIS develop devices?

At MIS it all starts with an idea. You come to us with your device concept, whether it's a napkin sketch or a product you've already begun to develop. We're ready to help with our decades of experience. Our dedicated quoting team will take a close look at your idea or device, understand your critical design requirements and provide you with a detailed estimate to meet your product milestones. From there, we leverage our phase-based design control process to bring your device to market on a sustainable and scalable platform.

How Do your Design Tools Work?

Getting an estimate for your component or device should be easy and fast. That's why MIS has developed several tools to make the process simpler for you.

Need an extrusion or balloon estimate? Use our online designers to enter your custom specifications and you will receive an email with your design. We'll follow up with an estimate within 24-hours. Click here to design your balloon, or here to design your extrusion.

Do you have a balloon catheter, steerable catheter, or reinforced shaft program you want quoted? We've got you covered. Our Catheter Design Templates are designed to gather all of the information we need to quote your project, allowing for a fast and efficient transfer of knowledge. Just download the form-entry-PDF and email it to info@midwestint.com! Have a different device you need quoted? No problem! You can request a quote here.

Do I need an Nda to work with Mis?

While it is common for both parties to sign an NDA before working together, it is not required. Our standard NDA is straight-forward and protects your information.

DOES MIS Have A quality System?

Yes, MIS does have a quality system! Quality is foundational to who we are as a company, and we pass quality down to every device that we design and manufacture under our roof. Our quality system is certified to ISO 13485:2016 and we thoroughly believe in strict design controls and good manufacturing and documentation policy.

How long does it take to receive a quote?

When you request a quote from us, we get to work immediately. Our quoting team will look at your device and any prints you have included make sure that we have all of the information we need to give you an accurate and detailed estimate. Once we have all of the necessary information, we aim to have a quote in your inbox within 3 business days for complex systems. For simpler projects you can expect a quote even faster, and we typically quote all balloon and extrusion requests within 24 hours!
