Adjustable bending delivery system / Adjustable bending sheath

Product Use:

This product can be used for transcatheter mitral/tricuspid valve repair, mitral/tricuspid valve replacement, and aortic valve repair procedures. It establishes a pathway between the patient's lesion site and the external operating end to deliver various diagnostic and therapeutic instruments, implantable devices, and medications to the lesion site, such as mitral valve clips, balloons, artificial valve stents, and observation lenses.

Product Structure and Composition:

The adjustable steerable delivery system consists of a controllable handle and a composite shaft (made of PEBAX, stainless steel wire, and PTFE). Multiple layers of steerable catheters are nested to achieve multi-degree-of-freedom bending and rotation.

Product Features:

1. The shaft exhibits strong kink resistance, pushability, and torque resistance, with a 1:1 torque response;

2. Excellent rebound performance after steering, with steering tension reaching over 250N;

3. Multi-layer catheter composite steering ensures smooth relative motion and stable trajectory;

4. The outer wall is smooth with good hydrophilicity and biocompatibility, while the inner wall is smooth and the inner layer is robust.
