S-wan™ Dual-Point Adjustable Curved Sheath

S-wan™ dual-point adjustable bending sheath is the world's first multi-point bending-controlled delivery sheath tube independently developed by H&H Medical. It is suitable for vascular access such as structural cardiac intervention, peripheral intervention and nerve intervention, with a diameter of 6Fr to 23Fr.
This product obtained the National Medical Products Administration (NMPA) registration certificate in 2023.

S-wan is currently the only domestically marketed bipolar adjustable sheath with dual-point steering capability in the same plane, providing robust support for passing instruments to reach the target stably. S-wan is compatible with instruments of 6-14Fr outer diameter and offers a wide range of lengths from 50-95mm. It is expected to become a new tool for surgeries in vascular surgery, neurovascular intervention, structural heart disease, electrophysiology, and other disciplines.

S-wan bipolar steerable sheath

The S-wan bipolar steerable sheath is entirely manufactured in-house by Huihe Medical, from tube braiding to product assembly. It can form an S-shaped bidirectional curve intracorporeally, accommodate 6-18Fr interventional devices, and perform complex maneuvers such as fenestration, crossover, and carotid artery superselection, enhancing surgical efficiency for physicians.

Product Features

Stable Support

Strong Support, No Recoil: Equipped with H&H Medical's FREEKNIT variable knitting technology, it significantly enhances support strength and prevents sheath recoil after device passage.

Predictable Control: Utilizes stepless torque transmission technology to achieve 1:1 torque transfer, precisely reaching the target position.

Bending Control Aesthetics

Bipolar Reverse S-Curve Design: The proximal curve provides support against the contralateral vessel wall, while the distal curve ensures stable device delivery and superselection to the target vessel.

0–270° Bending Control: Meets the superselection needs of various vessels.

R & D background and process

S-wan is a product that comes from clinical practice and serves clinical practice. is also the first product that Huihe Medical uses a digital platform for R & D and design. With the help of Huihe Medical's powerful simulation technology capability, the mechanical parameters of the sheath tube in hemodynamics are simulated, so as to determine the design parameters and complete the iteration with the optimal design.
