DELIVERY WIRE GUIDE AND THERAPEUTIC DEVICE Russian patent published in 2023 - IPC A61B17/221 A61F2/966 

FIELD: medical instruments.

SUBSTANCE: delivery wire guide and a therapeutic device. The delivery wire guide for delivery of a medical implant contains a core rod and a guiding element on the core rod. A recess is formed on the guiding element. The guiding element contains a body and a notch formed on the outer surface of the body. The notch forms a recess. The notch has a design corresponding to at least part of the design of the medical implant when the medical implant is in a coiled state. The notch mirrors the inner surface of a medical implant in a coiled state. According to the second embodiment, the delivery wire guide for delivery of a medical implant comprises a core rod and a guiding element on the core rod. A recess is formed on the guiding element. The guiding element contains an inner part and an outer part. The inner part is made of metal material and is fixed over the core rod. The outer part is made of polymer material and fixed over the inner part. The therapeutic stent delivery device comprises a delivery catheter, a medical implant, and the delivery wire guide described above. The delivery catheter defines a lumen extending axially through it, wherein the lumen is configured to receive a medical implant such that the medical implant is pressed against the wall of the lumen to assume a coiled state in which the medical implant is seated on the guiding element so that at least partially placed in the recess.

EFFECT: increase in the reliability of the delivery wire guide during the delivery of the stent is achieved and its delivery is facilitated.
