High-Performance Diagnostic Catheters for Advanced Cardiovascular Imaging

Diagnostic Catheters

Diagnostic catheters are essential medical devices used to navigate the vascular system and obtain critical information about cardiac anatomy and function. They facilitate the delivery of contrast media for imaging and the collection of physiological data.

Key Features:

• Material Composition: Typically constructed with biocompatible materials such as polyurethane or nylon, often reinforced with braided wire for enhanced torque control and kink resistance.

• Design Variations: Available in various French sizes (commonly 4F to 7F) and lengths (ranging from 65 cm to over 100 cm) to accommodate different patient anatomies and procedural requirements.

• Tip Configuration: Features soft, atraumatic, and radiopaque tips to ensure safe vessel engagement and precise visualization under imaging modalities.

• Lumen Size: Designed with large inner lumens to allow high flow rates of contrast media, enhancing image quality during angiographic procedures.

Notable Products:

• INFINITI™ Diagnostic Catheter by Cordis:

  • Material: Proprietary VESTAN™ Nylon for optimal torque and shape retention.
  • Sizes: Available in 4F, 5F, and 6F.
  • Design: True Lumen Design ensures consistent inner diameter from hub to tip, minimizing contrast jetting and improving catheter stability

• EXPO™ Diagnostic Catheter by Boston Scientific:

  • Material: Trilon material with full-length wire braiding for excellent pushability and torque transmission.
  • Sizes: Available in 5F, 6F, and 7F.
  • Design: Softer catheter shaft with a firm primary curve to enhance responsiveness and vessel engagement
