When you need an experienced catheter development and manufacturing team to support your microcatheter program, Midwest Interventional Systems is your turn-key solution. We leverage our design and development expertise in microcatheters, along with our strategic relationships with key component vendors to produce microcatheters with industry leading performance while maintaining thin wall construction and tight tolerances. By utilizing our experience, our clients are able to get to market faster and within budget.
By defining the design outputs at the beginning of our program
These outputs are driven by the anatomy, approach, and device or therapeutic to be delivered. We have direct experience in designing and developing microcatheter systems, which include:
Once the desired functional requirements are determined for your catheter system, our design engineers begin designing the components of the delivery system to achieve the desired outputs.
Mandrel and processing aid selection is critical in microcatheter design. Depending on the design requirements for the inner lumen of the microcatheter, there are several features that must be considered:
The next component MIS evaluates in the design process is the liner material for the main lumen of the catheter. Liners are lubricious material that line the inner diameter of lumens to reduce frictional forces from passing other instruments, catheters, devices. There are a number of options for liner material to incorporate into the delivery system, and they ultimately depend on the application. Common liner materials typically consist of:
Liner thicknesses for microcatheters can vary, but we have experience in working with liners that have a single wall thickness of 0.0005”.
The next layer to a microcatheter delivery system is typically a reinforcement layer. The reinforcement layer plays a critical role in the overall device torquability, achievable bend angles and bend diameters, kink resistance, and pushability. Depending on the application of the device, performance requirements, and other interacting devices, MIS engineers have a plethora of options in their catheter reinforcement toolbox, including, but not limited to:
- Braid Reinforcement
Wire thicknesses as low as 0.0005”.
- Coil Reinforcement
- Braid/Coil Hybrid
The final layer in constructing a microcatheter is the jacket, or medical extrusion. The extrusions provide coverage over the reinforcement layer of the catheter and are also critical to the device torqueability, flexibility, compression and elongation resistance. MIS will help in developing a number of specifications surrounding these jackets, which include:
