WIPO Patent Application WO/2023/066065
Kind Code:
A1
Abstract:
The present application provides an implantable medical device and a medical wire thereof, being applicable to implantable medical devices. The medical wire comprises: at least two strands of twisted wires; the at least two strands of twisted wires are spirally wound along the axial direction of the medical wire; and the at least two strands of guide wires are twisted to form a strand of twisted wire. Multiple guide wires are twisted to form a twisted wire; multiple strands of twisted wires are spirally wound to form a medical wire; on the one hand, when the number of guide wires is increased, the diameter of the medical wire is not obviously changed and can be strictly controlled, damage caused by invasion operation is avoided, and the space utilization rate is high; and on the other hand, the screw pitch between coils of each twisted wire in the medical wire is reduced, such that the medical wire has better flexibility and stretchability, thereby reducing the foreign body sensation of implantation.
