Dilatation catheter

blood vesselballoondrug eluting

Overview
Nordson MEDICAL designs, develops and manufactures medical balloons with fully integrated in-house capabilities: extrusion, tooling design, manufacturing and testing. The company supports rapid prototype-to-production transition and high-volume manufacturing.

Key attributes

• Complex geometries: multi‑lumen, bent, offset and stepped designs
• Wall constructions from ultra‑thin to thick; non‑compliant to highly compliant
• Material options: PET, Nylon, Polyurethane and other thermoplastic elastomers
• Coating options: hydrophilic/hydrophobic, antithrombogenic, abrasion‑resistant, drug‑release, conductive, reflective

Applications

• Dilatation: high‑pressure balloons for lumen dilation (including coronary, esophageal, ureteral and valvular applications)
• Stent delivery: low‑compliance, high‑pressure balloons for stent deployment and post‑dilation
• Positioning: offset/asymmetric and dog‑bone shapes for targeted device alignment in complex anatomy
• Occlusion: low‑pressure elastomeric balloons for cavity filling and temporary occlusion
• Endovascular graft delivery: balloons to deploy and secure grafts to vessel walls
• Energy & light delivery: ultra‑thin wall and optically clear balloons for thermal or photonic therapies
• Drug delivery: dual‑balloon or sealing shapes for localized therapeutic delivery
