Distal Access Catheter: The “Pathway Engine” for Multi-Device

Interventions

In complex interventional procedures, clinicians use a variety of tools: guidewires, balloons, stents, microcatheters, aspiration systems, and embolic agents. All of them rely on one critical foundation—a stable access pathway.
The Distal Access Catheter is engineered for this role. Acting as a “pathway engine,” it supports, guides, and enables smooth transition between tools, making it the central link between operator control and lesion access.

Why Is It the First Step in an Interventional Chain?

✅ 1. Reinforced Structure for Push and Support

This catheter features a multi-layer design, including a low-friction PTFE inner liner and a high-density stainless steel braid for external support. It can smoothly navigate deep or tortuous anatomy while providing enough backup support to facilitate device delivery—especially useful for balloons, stents, or microcatheters.

✅ 2. Smart Material Selection for Smooth Device Passage

The PTFE inner lumen significantly reduces resistance for guidewires, microcatheters, and stent systems. This minimizes the risk of wire kinking, device sticking, or delivery failure—especially critical in calcified or narrow arteries.

✅ 3. Large Inner Lumen for Multi-Device Compatibility

Designed with a spacious internal diameter, the catheter allows for combined use of multiple tools, such as a guidewire + microcatheter + balloon system. This enhances workflow by reducing the need for repeated exchanges.

✅ 4. Clear Tip Visibility for Confident Navigation

With a platinum-iridium radiopaque marker at its tip, the catheter provides real-time visibility under fluoroscopy, helping physicians accurately judge its position and prepare for the next procedural step.

Typical Use Combinations:

• With Microcatheters: In neurointerventions, the distal access catheter acts as a launch pad for microcatheters to reach distal brain vessels.

• With Aspiration Systems: In thrombectomy cases, it can serve as a supportive conduit or direct aspiration catheter, increasing suction force.

• With Balloons or Stents: In coronary CTOs, it offers the backup force needed to cross and treat occluded segments.

✅ Conclusion: Stable Access Drives Procedural Success

Every tool in an interventional procedure depends on a secure, flexible, and supportive main route. The Distal Access Catheter, through smart structure and material engineering, becomes more than just a tube—it becomes the backbone of the intervention, enabling safe, smooth, and efficient device operations from start to finish.
