Embodiment Construction

[0034] The sheath is an important part of the delivery system for minimally invasive interventional therapy. Compared with the operating doctor, the proximal area of ​​the sheath is the closest, and the opposite is the distal area. According to the difference in performance requirements of the sheath for specific operations, the stiffness of the proximal region and the distal region of the sheath can be the same or different. Typically, the proximal region is stiffer than the distal region to provide better forward pushing performance; the distal region is more compliant than the proximal region to provide better tracking of the delivery system through tortuous vessels sex. Depending on the pushability, trackability or other properties required of the delivery system, a multi-layered structural design may be used in the proximal region, or in both the proximal region and the distal region.

[0035] Therefore, the present invention proposes a reinforced composite sheath with a...

Abstract

The invention discloses a reinforced compound sheathing canal, a preparation method and application thereof. The reinforced compound sheathing canal sequentially comprises an inner layer, a reinforced layer and an outer layer from interior to exterior, wherein the reinforced layer comprises axial reinforcing elements and a spiral reinforcing element, the spiral reinforcing element is a single spiral element or is formed by combining two or more spiral elements, the axial reinforcing elements are disposed on the inner side or outer side of the spiral element, or are inserted between the spiral elements, and various axial reinforcing elements are uniformly arranged in the circumference direction of the sheathing canal. The reinforced compound sheathing canal provided by the invention has the advantages of thin wall, high axial strength, high radial strength, high torque transitivity and the like, can be applied to a transport system for transporting medical device implants needed in a minimally invasive treatment and can reduce the outer diameter of the transport system, so that the medical device implants are easy to arrive at lesion positions, damage to the blood vessel of a patient is reduced, and sufficient technical support is provided for reliable, successful and safe transport and implantation of the medical device implants by the transport system.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a reinforced composite sheath commonly used in interventional device delivery systems. Background technique [0002] Minimally invasive interventional therapy is a surgical treatment method performed under image guidance. During the operation, medical device implants or drugs are delivered to the lesion with minimal trauma through the delivery system for physical, mechanical or chemical treatment. . Among them, the sheath, as an important part of the delivery system, has been widely used in minimally invasive interventional therapy. [0003] For the minimally invasive interventional treatment of blood vessels, the operating doctor usually makes an anatomical incision or performs puncture on small blood vessels (such as the femoral artery) to form an entrance, and then implants medical devices such as stent grafts through the entrance and small blood vessels with the help...
