Ultimaster™ Tansei™
Mastering Complexity. Simple.
In clinical practice, where ~80% of cases can be expected to be complex1, it is more important than ever to have tools you can trust for PCI. Ultimaster™ Tansei™ provides enhanced pushability2 and excellent kink resistance2 with a stainless steel tapered core wire at the exit port and advanced shaft technology. With this new DES Terumo introduces a durable yet flexible tip2, specially developed for complex stenting procedures. This innovation will improve the deliverability2 of the whole stent system versus leading stent delivery systems.
Building on the heritage of Ultimaster™ with its proven clinical performance3, Ultimaster™ Tansei™ utilises the same abluminal gradient bioresorbable polymer coating to support early vascular repair4.

Building on the heritage of the Ultimaster™ stent
Ultimaster™ Tansei™ has all the key features of Ultimaster™ for supporting vascular repair1.
Innovative abluminal bioresorbable coating
- Drug coating applied in a gradient to reduce the risk of polymer cracking and delamination, even when the stent is overexpanded
- PCL added to PDLLA, increasing the elasticity of the bioresorbable polymer coating
Simultaneous polymer resorption and drug release within 3–4 months, to macth the procedure-triggered biological response
No drug coating on parts of the stent that experience the most physical stress.
Polymer integrity
Gradient coating maintains polymer integrity for reduced risk of delamination, even when overexpanded14
A tip designed to facilitate treatment of the most challenging cases
Updated design to maximize deliverability, even in the most challenging cases
- Flexible tip material: supports navigation through tortuous vessels
- Low passing resistance at the tip: minimizes the force required to cross challenging lesions
A tip specifically developed with the composition and shape to support durability
- Rounded shape: offers durability and crossability, even through areas of calcification
- Durable material: reduces the risk of tip damage when navigating challenging anatomy
Advanced shaft technology for outstanding acute performance
Maximizing transmission force, and kink resistance9
- Shaft reinforced with a stainless steel core wire: ensures optimal pushability and transmission force
- Stronger hypotube: maximising kink resistance for effective and reliable deliverability
Ensuring a smooth and balanced transition
- A stainless steel tapered core wire at the exit port for optimal pushability across the entire delivery system
Keep ahead of the curve in complex anatomy
Enhanced deliverability
In practice, where ~80% of cases can be expected to be complex1, it is more important than ever to have tools you can trust for percutaneous coronary intervention.
Ultimaster™ Tansei™ has been developed with challenging cases in mind, achieving optimal trackability and pushability11, which are essential for reliable delivery.
Combination of key features to optimize its use in complex bifurcation anatomy
Open cell, 2-link design eases side branch access – essential for effective bifurcation stenting
Uniform scaffolding enables optimal coverage of bifurcation anatomy
Good overexpansion capacity
- Post dilatation limit up to 5,5mm12
- Up to 5.8 mm showed in independent benchtest results13
Gradient Coating Technology
No drug coating on parts of the stent that experience the most physical stress
Ultimaster™ Tansei™ has been developed with challenging cases in mind, achieving optimal trackability and pushability, which are essential for reliable delivery.
