Delivery guidewire and therapeutic treatment device

Abstract

The present invention relates to a delivery guidewire and a therapeutic treatment device including the delivery guidewire. The delivery guidewire includes a core shaft and a driving member arranged on the core shaft, and the driving member includes inner and outer components. The inner component is made of a metal and fixedly sleeved over the core shaft, and the outer component is made of a polymeric material and fixedly sleeved over the inner component. The inner component fixedly sleeved over the core shaft indirectly enhances attachment of the outer component to the core shaft, thus reducing the risk of loosening, wrinkling or displacement of the outer component and resulting in improved safety and reliability of the delivery guidewire during use.
