| titleOfInvention | Guiding catheter and guiding catheter system |
| abstract | A guiding catheter (100), comprising a catheter main body (110) extending in an axial direction, wherein the catheter main body (110) comprises an inner-layer catheter body (111), an outer-layer catheter body (113), and an intermediate layer (112) located between the inner-layer catheter body (111) and the outer-layer catheter body (113); the intermediate layer (112) is configured to have a relatively high rigidity; the intermediate layer (112) is provided with an opening (300) extending in an axial direction; the inner-layer catheter body (111) is configured to have an inactive extending area (200) extending in a circumferential direction; and the inactive extending area (200) is at least partially accommodated in the opening (300) of the intermediate layer (112). Further provided is a guiding catheter system, comprising the guiding catheter (100). The inactive extending area (200) provided on the inner-layer catheter body (111) enables the outer diameter of the guiding catheter (100) to be less than other guiding catheters of non-expansible inner diameters; and when delivering an instrument with the same specifications, the guiding catheter of the present invention more easily passes through a circuitous blood vessel to reach a designated position during a puncturing and subsequent positioning process, thereby having a smaller delivery resistance, and thus less damage is done to an inner cavity of the blood vessel. |
