摘要： A catheter and a micro catheter (10) for nerve intervention are provided, and the catheter wall of the catheter comprises a smooth layer (23), a reinforcing layer (24) and an outer covering layer (25) in the order from inside to outside. The smooth layer (23) and the outer covering layer (25) are both made of polymer materials. The reinforcing layer (24) is a supporting layer, which is connected with the smooth layer (23) and the outer covering layer (25) respectively, so as to connect the respective layers of the catheter together. The catheter comprises a proximal portion (11) and an extension portion in the direction from the proximal end to the distal end. The reinforcing layer (24) assumes a braid structure at the proximal portion (11), and assumes a helix structure at the extension portion.

摘要： The present application discloses a surgical apparatus for aneurysms comprising: a stent, a delivery guide wire, an introducer sheath and a microcatheter, wherein: the stent is a self-expanding stent; the delivery guide wire outside of which the stent is restrained to is provided in a lumen of the introducer sheath; the introducer sheather is connected with the microcatheter, with lumens communicating, to form a passageway through which the delivery guide wire and the stent are delivered into a human body. The surgical apparatus for aneurysms provided in the examples of the present application is able to deliver and release the stent which has high density and is super soft to a vascular lesion. A lattice structure of the stent is of high coverage at the vascular lesion such that the stent released into the vessel produces the same effects as healing of parent vessel, and thus improves the treatment of vascular aneurysms.
摘要翻译： 本申请公开了一种用于动脉瘤的手术装置，包括：支架，输送导丝，导引鞘和微导管，其中：支架是自扩张支架; 引导器护套的内腔中设置有限制支架的输出导丝， 引导器护套与微导管连接，流体连通，以形成通道，输送导丝和支架通过该通道输送到人体内。 在本申请的实施例中提供的用于动脉瘤的手术装置能够输送和释放具有高密度且对血管病变超柔软的支架。 支架的晶格结构在血管损伤处具有高覆盖率，使得释放到血管中的支架产生与母体血管愈合相同的效果，从而改善血管动脉瘤的治疗。

摘要： A medical guide wire comprises a metal core (1), a coil (2), a delivery element (3) and a boss (4). The metal core (1) has a variable-diameter structure, which consists of a linear structure (1-3), a stepped structure (1-2) and a linear structure (1-1) from a proximal end to a distal end. The number of the coil (2) is one or more, and the coil(s) is/are fixed on the linear structure (1-1) and the stepped structure (1-2) at the distal end of the metal core (1). The number of the delivery element (3) is one or more, and the delivery element(s) is/are fixed to the stepped structure (1-2) of the metal core (1). The boss (4) is fixed on the stepped structure (1-2) of the metal core (1) behind the delivery element (3). When the medical guide wire is delivering an implant instrument, the delivery element on the medical guide wire makes each segment of the implant instrument receive even resistance by rubbing the inner wall of the implant instrument, thereby integrally delivering the implant instrument into the human lumen.
摘要翻译： 医疗导丝包括金属芯（1），线圈（2），输送元件（3）和凸台（4）。 金属芯（1）具有可变直径结构，其由线性结构（1-3），阶梯结构（1-2）和线性结构（1-1）组成，从近端到远端 。 线圈（2）的数量为一个或多个，并且线圈（一个或多个）固定在线性结构（1-1）和金属芯的远端处的台阶结构（1-2）上 1）。 输送元件（3）的数量是一个或多个，输送元件（一个或多个）被固定到金属芯（1）的阶梯状结构（1-2）。 凸台（4）固定在输送元件（3）后面的金属芯（1）的台阶结构（1-2）上。 当医用导丝输送植入器械时，医用导丝上的输送元件通过摩擦植入器械的内壁而使植入器械的各段受到均匀的阻力，从而将植入器械一体地输送到人体管腔中。
