In modern medical technology, vascular interventional surgery is developing at an unprecedented pace, especially in the treatment of coronary and peripheral artery diseases. The performance of the catheter directly affects the success of the procedure.

Borrowability: Precise Access to Complex Lesions

In vascular interventional surgery, boroughability is one of the core indicators of catheter performance, especially when dealing with complex lesions (such as chronic total occlusion or highly calcified lesions). Excellent boroughability not only improves the ability of guidewires and catheters to pass through stenotic or occluded lesions, but also reduces the difficulty of the surgeon's operation, thereby shortening the operation time.

·Low-friction coating: Utilizing high-tech coatings (such as PTFE or hydrophilic coatings), the coefficient of friction with the vessel wall is significantly reduced, ensuring smooth passage of the catheter through narrowed areas.

·Tap-shaped flexible design: Flexible materials and a tapered structure are used at the distal end of the catheter to improve boroughability and vascular adaptability, while protecting the fragile vascular intima.

·High-precision manufacturing: Utilizing laser cutting and micro-welding processes, extremely high concentricity of the catheter's inner and outer walls is achieved, ensuring stability and precision even under extreme operating conditions.

Torsion resistance: Flexible and reliable operation.

Besides passability, torsion resistance is another key performance characteristic. Excellent torsion resistance allows the catheter to transmit more precise force and torsion in complex pathways, better meeting the needs of physicians.

·Multi-layer composite structure: Embedding a metal braided layer or employing a multi-layer design combining Pebax and nylon not only enhances the catheter's torsion transmission capability but also strengthens its pressure resistance.

·Balance of high pushing force and maneuverability: Optimizing the proximal rigidity and distal flexibility of the catheter allows it to provide both powerful pushing force and precise transmission during torsion.
