Introduction
Coronary lesions often exhibit certain features posed as challenging while performing a percutaneous coronary intervention (PCI) viz. thrombus, bifurcation, ostial lesion, calcification, and chronic total occlusions (CTOs) (1). The use of microcatheters as a coronary interventional tool assists in performing invasive endovascular procedures by serving a broad range of functions in these complex vessel anatomies.
The objective of this article is to formulate and deliberate on the recommendations for the selection of microcatheters and their utility in coronary interventional procedures. The discussion included broadly the following two topics:
• Understanding the significance of a microcatheter in the cardiac catheterization lab—which included a discussion on the types of microcatheter available in the Indian market and their significance in PCI procedures.
• Criteria for the selection of microcatheters—which included a discussion on the selection and preference of one microcatheter over another based on lesion/anatomy-specific criteria or hardware characteristics.
TAPERED STAINLESS STEEL BRAID CONSTRUCTION FOR OPTIMAL GUIDEWIRE SUPPORT
FINECROSS MG stainless steel braid construction is designed to provide strength, responsiveness and support for improved pushability to access and cross complex lesions.
13cm FLOPPY DISTAL SEGMENT FOR SUPERIOR TRACKABILITY
The distal 13 cm is ultra flexible for improved trackability around tight bends and tortuous anatomy. The floppy distal segment is designed to be atraumatic and provide an optimal balance between trackability and safety while navigating through the tortuous anatomy.
TAPERED OUTER DIAMETER FOR SUPERIOR CROSSABILITY
The outer diameter of the stainless steel shaft tapers from a proximal 2.6Fr. to a distal 1.8Fr. designed for improved crossability and guidewire handling.

Structural Properties/Characteristics of Microcatheters
As per the experts, multiple microcatheter features impact its selection viz. tip profile, shaft profile, tip and shaft flexibility, inner lumen diameter, radiopacity of the device, and microcatheter tube structure a.
Conclusion
Thus, microcatheter selection and operating techniques are vital to a successful treatment plan, which should be based on the recommendations derived for clinical expertise and operator efficiency. For next-generation microcatheters, an increase in support without compromising on flexibility and lowering of the tip profile in comparison to the ones currently present in the market is needed.

Guide catheters are required for all coronary interventions to provide access to the coronary ostium and support equipment delivery. The ideal guide provides stability for device advancement through the coronary anatomy, while minimizing vessel trauma and allowing for vessel opacification.
The catheter is guided to the narrowed artery. Then, a smaller balloon catheter is inserted through the flexible catheter and inflated at the narrowed area to open it. Often, the doctor will also place a mesh coil called a stent at the narrowed part to help keep the artery open.

PTCA Balloon Ryurei
Description
Confidence in your hands
Ryurei™ has superior crossability1 thanks to the combination of low distal profiles and Terumo’s hydrophilic M coating. The short balloon bonding and reinforced shaft1 results in enhanced trackability1 while maintaining excellent pushability1.
These features can increase physician’s confidence in success even during complex procedures.
CharacteristicsExcellent Pusability
The combination of flexible distal part, tapered core wire on the midshaft and the thick proximal hypotube, results in smooth and balanced transition across the entire catheter for high transmission force, resulting in excellent pushability
Superior Crossability2
Thanks to the combination of distal low profiles and the Terumo hydrophilic M-Coat, Ryurei offers low friction in crossing tight lesions
Enhanced Trackability2
With an optimal tip design and improved balloon bonding, Ryurei provides enhanced trackability, even in tortuous anatomy and difficult to navigate vessels.
