Embodiment Construction

[0193] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0194] It should be noted that when a component is said to be "connected" to another component, it may be directly connected to the other component or intervening components may also exist. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time.

[0195] Unless otherwise defined, all technical and scientific terms used herein have the same ...

Abstract

The invention discloses a bending-adjustable sheathed catheter and a delivery system employing the same. The bending-adjustable sheathed catheter comprises a catheter body with a far end and a near end. A drawing wire is connected to the wall of the catheter body. One end of the drawing wire extends to the near end of the catheter body. The joint of the other end of the drawing wire and the catheter body is adjacent to the far end of the catheter body. At a position adjacent to the far end of the catheter body, at least one section of the drawing wire is exposed outside the catheter body. Since one section of the drawing wire in the bending-adjustable sheathed catheter is exposed outside the catheter body of the sheathed catheter, a posture convenient for force application during drawing is achieved; the point of strength can be changed in a self-adaptive manner through movement relative to the catheter body; under the condition that the turning radius is large or introducers are long,hard and less prone to bent, safety and flexibility in operation are improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a bend-adjustable sheath and a delivery system using the bend-adjustable sheath. Background technique [0002] Interventional surgery causes little trauma to the human body and is less invasive. It is a medical technology that has been rapidly emerging and promoted in recent years. A channel is established between the lesion site and the external operation terminal to introduce diagnostic and treatment instruments, drugs, interventional instruments, etc. to the lesion site. The interventional diagnosis and treatment sheath has a distal end and a proximal end. The distal end can enter the vascular system of the human body, and the proximal end is connected to the operating handle. Other auxiliary instruments are punctured into the blood vessel, and the physician controls the distal end of the sheath along the pre-established guide wire track to the lesion to r...
