type A

●Appropriate wedge-shaped transition
Wedge-shaped transition between dilator and sheath provides smooth and spontaneous insertion for catheter sheath, lowering damage to blood vessel
●Excellent lubricity and radiopacity
Sheath adopts PTFE+Bi2O3, bearing excellent lubricity and radiopacity
●Excellent radiopacity
Dilator adopts PP+BaSO4, bearing excellent radiopacity
●No plasticizer
Being safer for sidearm adopting TPU, no plasticizer DEHP 
●Haemostatic valve
Unique design of haemostatic valve prevents blood flowing out and provides convenient operation for guidewire and catheter

type BCD

●Excellent flexural-resistance and compliance
PTFE inner layer ensures smooth advancement 
stainless steel inner layer ensures excellent flexural-resistance
PA outer layer ensures smooth advancement inside bloold vessel 
●Safe and humanized design to lower operational risk
Perfect matching between sheath and dilator to reduce damage to blood vessel during operation; 
Mark band with non transparent X ray on sheath distal end to locate.
●Variety of specifications and types for more applications
●Hydrophilic coating for easy insertion 
Hydrophilic coating over sheath surface to provide a smooth surface for insertion
●Type D: Y-valve
Design of Y-valve prevents aeroembolism, reduces blood leak, being convenient for operation. No Y-valve in A/B/C.
