Abstract: A catheter reinforcement layer (100) and a catheter (10). The catheter reinforcement layer (100) includes a spring component (110) and at least one axial component (120). The at least one axial component (120) extends along the spring component (110) from a proximal end to a distal end, and has at least one intersection with the spring component (110). According to the catheter reinforcing layer (100), by introducing one or more axial components (120) into a reinforcing layer of an existing spring component (110), the axial modulus of the catheter (10) is increased, thereby avoiding axial deformation or even breakage of the tubular body of the catheter (10) due to axial force.

Abstract: A vascular stent is disclosed, the vascular stent being a self-expanding braided tubular structure constructed from interwoven first and second components, or from interwoven second component interwoven. The first components include at least one first braid wire (11), each first braid wire (11) including a first wire core (111) and a cladding jacket (112) covering the first wire core (111). The second components include at least one first braid wire (11) and at least one second braid wire (12). The vascular stent is wholly fluoroscopically visible so that its boundaries can be identified during a surgical procedure, allowing a physician to clearly determine whether the vascular stent has adhered to a blood vessel wall. Moreover, the vascular stent provides strong support.

Abstract: An aneurysm occlusion device (10), a therapeutic apparatus for aneurysm occlusion and an aneurysm occlusion system are disclosed. The aneurysm occlusion device (10) includes at least an expandable mesh structure (11) having an expanded configuration with a planar spiral shape and a compressed configuration for delivery into an aneurysm (30) from a blood vessel. The expandable mesh structure (11) can be compressed within a catheter (40) and can recover the expanded configuration with the spiral shape after being released from the catheter (40). The aneurysm occlusion device (10) achieves stable, compliant packing while providing the advantages of among others, avoiding rupture of the aneurysm (30), preventing thrombosis in a blood vessel, increasing coverage of an opening at the aneurysm neck, promoting thrombosis in the aneurysm and accelerating embolization of the aneurysm (30).

Abstract: A release apparatus (100), a release system, a release method, and a treatment apparatus are disclosed. The release apparatus (100) uses two indicators, electric current and power comsuption, to determine whether the release process performed by the release system is successful. This reduces misjudgments, improves the accuracy of the determination of the release state. The release system also uses a self-loop structure, such that it is unnecessary to insert a conductive needle or electrode into the body of a patient, reducing the suffering of the patient.

Abstract: An embolic coil conveying device and a preparation method thereof are disclosed. The embolic coil conveying device includes a pusher and an embolic coil. A distal end of the pusher and a proximal end of the embolic coil are connected to serve as a detachment section. A stretch-resistant thread is disposed in the embolic coil. The stretch-resistant thread is fixed at the proximal end of the embolic coil. A conductive wire is disposed in the pusher. The stretch-resistant thread is connected to the conductive wire. Compared with the prior art, the present invention has the advantages that the stretch-resistant thread is fixed at the proximal end of the embolic coil, so that the stretch-resistant thread is connected to the conductive wire, thereby reducing the length of the detachment section, making the detachment section more flexible, and avoiding kick-out of a microcatheter due to release of the embolic coil.

Abstract: An electrolytic detachment mechanism and an electrolytic detachment device are disclosed. The electrolytic detachment mechanism is intended for cooperation with an electrolytic detachment apparatus to achieve an electrolytic detachment of an implant. The electrolytic detachment mechanism includes the implant, a detachment member (103), an electrical conduction member (101) and an absorption member (102). When absorbing electrolytes, the absorption member (102) will maintain electrical conduction between the detachment member (103) and a cathodic conductive element, thus resulting in enhanced electrolytic detachment reliability and overcoming the problems of a long detachment time and required multiple detachment attempts associated with existing electrolytic detachment devices.

Abstract: An embolization device and a coil thereof (10, 20, 30) are disclosed. The coil (10, 20, 30) is formed by joining together at least four structural elements arranged in different planes, which include at least two C-shaped elements (12) and at least one O-shaped element (13) or ?-shaped (11) element. The at least two C-shaped elements (12) are arranged in two adjacent planes and are sequentially joined together to form an S-shaped structure. The embolization device preferably includes plurality of coils (10, 20, 30) which are joined together side-by-side and end-to-end, wherein in any adjacent two coils (10, 20, 30), one is swivelable about an axis of the embolization device with respect to the other. The ?-shaped element is structurally stable, allowing the coil (10, 20, 30) to maintain good structural stability. At the same time, the three-dimensional S-shaped structure has good deflectability, which imparts high compliance to the coil (10, 20, 30).

Abstract: A catheter shaft in accordance with one embodiment of the present invention comprises a support member including a distal end, a proximal end, and a plurality of elongate flanges extending therebetween. Each elongate flange has a fixed end and a free end. The fixed end of each flange being fixed to a central portion of the elongate support member. In a preferred embodiment, a sheath is disposed about the support member of the catheter shaft.

Abstract: The present invention relates to a medical device comprising at least one tubular member having an inner surface and an outer surface. The inner surface of the tubular member is at least occasionally subjected to contact with at least one second surface. The tubular member therefore comprises a hydrophilic lubricious coating disposed on its inner surface to reduce the friction between the inner surface of the tubular member and the second surface which is caused by movement.
