Provide customized high-quality sea tubes

Raw material: Medical grade stainless steel 304L

Diameter(mm)	Length(mm)	Wall Thickness(mm)	PTFE Coating Thickness(um)
0.2~1.5	300~2100	0.03~0.18	5~15

Technical advantages:

① High precision in inner and outer diameter dimensions, with wall thickness uniformity controllable within 3 μ m
② The optimal external surface roughness can reach Ra<0.2 μ m
③ The optimal inner surface roughness can reach Ra<0.6 μ m
④ The coating thickness is 5-15 μ m

Purpose:
A hypotube is a long metal capillary tube that is an important component of minimally invasive therapeutic catheters, used in conjunction with balloons and stents to open arterial blockages. The balloon part of the catheter is attached to the distal end of the hypotube. The hypotube enters the human body and pushes the balloon along the tortuous long blood vessels towards the site of arterial blockage. During this process, our hypotube can achieve resistance to twisting and bending, and can smoothly push, track, and rotate within the human body structure.
