Title:
CATHETER REINFORCING LAYER AND CATHETER
Document Type and Number:
WIPO Patent Application WO/2022/166539
Kind Code:
A1
Abstract:
A catheter reinforcing layer (100) and a catheter (10). The catheter reinforcing layer (100) comprises a spring component (110) and at least one axial component (120), the at least one axial component (120) extends from a proximal end to a distal end along the spring component (110), and the at least one axial component (120) has at least one intersection point with the spring component (110). According to the catheter reinforcing layer (100), by introducing one or more axial components (120) into a reinforcing layer of an existing spring component (110), the axial modulus of the catheter (10) is increased, thereby avoiding axial deformation or even breakage of the tube body of the catheter (10) due to axial force.
