PERIPHERAL VASCULAR

Below-the-knee Stent Delivery Catheter

Good push-ability is often traded for a thinner profile in catheter design, particularly for below-the-knee procedures.

For this project, our customer required a stent delivery catheter with both performance characteristics to enable access deep in the popliteal artery.

Challenge:

The requirement for this device was to have an ultra-low catheter profile (sub 0.004″/0.10 mm) combined with enhanced push-ability to deliver treatments to areas of the body, which are typically difficult to reach.

Solution:

In collaboration with our wider engineering team at Zeus, we specified the optimum polymer profile and designed a custom reinforcement method to strengthen the catheter without sacrificing wall thickness. Functional prototypes were quickly developed for pre-clinical trial testing using our rapid prototyping capability.

Outcome:

Pre-clinical test results indicate the design performs with superior efficacy to precisely navigate below-the-knee and accurately place stents in previously thought impossible locations. Based on these excellent results, validations are underway.

“Their expertise in catheter design and their prototyping capability was crucial. Creating a holistic solution allowed us to optimize our device to meet clinical demands.”
