Coronary Catheter

Coronary CTO Microcatheters

Coronary CTO (chronic total occlusion) microcatheters are specialized catheters specifically designed for treating chronic total occlusions in the coronary arteries. These advanced microcatheters play a crucial role in CTO procedures, enabling precise navigation through the blocked coronary artery to reach the exact site of the occlusion.

We provide a full range of coronary CTO microcatheter solutions to support every phase of the product life cycle:

  • Design and development of coronary CTO microcatheters.
  • Transfer of products and processes from one site to another to support product-line transfer, line duplication, low-cost manufacturing, and prototype-to-production migration.
  • Manufacture of standard and custom cardiovascular medical-device components, including polyimide-coated wire, high-spring constant coils, braided shafts, polyimide tubing, braided multi-lumen extrusions, PT electrodes and marker bands, welded electrode assemblies, coated stainless wire-welded pull cables, thermocouples, micro-machined ablation tips, micro-molding, and machined and molded handles.
  • Design for manufacturability (DFM) to assure that final products can be repeatedly manufactured while meeting quality, reliability, and performance requirements.
  • Clinical and regulatory expertise through our physician advisory board; preclinical product evaluation; validated test methods; and medical device registration, reporting, and vigilance.

With comprehensive manufacturing capabilities, we develop cardiovascular catheters and cardiovascular sheaths in a wide range of models and configurations. Our technical experts ensure the highest-quality materials are matched to the precise design specifications and requirements of every cardiovascular component and cardiovascular device we manufacture.

We maintain ISO 13485 certification across our facilities, as well as quality and process management systems that meet the highest standards set by the United States Food and Drug Administration, the European Community, and other international regulatory authorities. Our technical experts ensure design for manufacturability to decrease development time, minimize costs, and achieve speed to market.

We maintain strong R&D investment to develop new technologies that complement customer initiatives to incorporate electrical and optical capabilities into catheters and sheaths. Throughout our partnership, we provide the mechanical design, process design, device testing, material testing, inspection, traceability, and documentation required to meet complex and sophisticated requirements. We support customers with the following catheter enabling platforms:

  • Mechanical competencies in delivery platforms, materials joining and precision coating to develop miniaturized sensor, electrical, and optical components.
  • Advanced electrical and optical design capabilities in fine wire joining, proximal ring connectors, sensor connector attachment, optical fiber connectors, optical fiber polishing, and wire bonding.
  • Clinical and design assurance to perform benchmark testing, technology research, and clinical evaluation.
