Update Medical Transradial Coronary Stent System with Iso Certificate

What is the structure of coronary stent system?

Coronary stent system consists of support and conveying system.

The support is made of cobalt chromium alloy, whose surface is completely covered with amorphous silicon carbide coating. The support is divided into three designs: small one that support diameter of 2 to 3mm, medium one that support diameter of 3.5 to 4mm and large one with support diameter of 4.5 to 5mm.

The delivery system is a fast exchange PTCA catheter with an effective length of 140cm. The balloon is made of polyether block amide. The outer tube of the catheter is made of nylon and the inner tube of the catheter is made of HDPE. The proximal end of the catheter is coated with hydrophobic coating and the distal end is coated with hydrophilic coating.

In order to facilitate the observation and positioning of the support under fluoroscopy, the support is set between two ray detectability marks. The proximal rod of the coronary stent system is a sea wave tube with a port to connect the balloon for filling and retracting the balloon. The catheter cavity starts at the head end of the conveying system and ends at the guide wire penetration point with 29cm away from the distal end. The conveying system is compatible with guide wire with diameter of 0.014mm and guide tube with inner diameter than 0.056mm.

To understand when the head of the delivery system passes through the guide tube, there are shaft rod penetration marks on the sea wave tube at 92cm and 102cm from the distal end of the delivery system. The shaft seat is equipped with a snap in sea wave tube clamp frame, which should be used when the support system is placed on the preparation platform.
