Anterior cruciate ligament (ACL) is one of the most susceptible ligaments of the knee that can suffer injury. These ruptured ligaments can be treated through surgical intervention using a braided structure that either acts as a substitute graft in isolation or an augmentation device alongside the biological tissue. Therefore, the main objective of the research work is to present an analytical model for predicting the complete set of tensile properties of braided prosthesis consisting of multifilament strands based upon predefined braid geometry and constituent material properties. The model has also accounted for the kinematical changes under defined loading conditions. The research findings have been confirmed by making a comparison between the theoretical and experimental results. The tensile properties of braided prostheses predicted via analytical route matched reasonably well with the experimental results.

Objective: The purpose of this study was to investigate the timing and mode of failure of metallic screw-type suture anchors used to attach artificial tendons to bone in an New Zealand White rabbit model.
Study Design: Metal suture anchors with braided composite sutures of varying sizes (United States Pharmacopeia (USP) size 1, 2, or 5) were used to secure artificial tendons replacing both the Achilles and tibialis cranialis tendons in 12 female New Zealand White rabbits. Artificial tendons were implanted either at the time of (immediate replacement, = 8), or four/five weeks after (delayed replacement, = 4) resection of the biological tendon.

Background: Lack of a dedicated thrombectomy device for cerebral venous thrombosis hinders the recanalization ability of endovascular treatment (EVT). Novel NiTi-braided stent retriever (Venous-TD) is a dedicated venous sinus thrombectomy device. This study aims to demonstrate the safety and efficacy of Venous-TD.

This study investigates the mechanical behaviour of poly(ɛ-caprolactone) (PCL) continuous filaments produced by a novel electrospinning (ES) method. These filaments can be processed into woven or braided structures, showing great promises as scaffolds for ligament and tendon repair. Mechanical characterisation of the filaments using DMA and uniaxial tensile tests shows that the filament response is viscoelastic-viscoplastic.

Intracranial aneurysm is a common cerebrovascular disease with high morbidity and mortality. Endovascular interventional therapy has advantages of high efficiency and minimally invasive. In this paper, the technical development of intracranial aneurysm interventional therapy Instruments was introduced, by interpreting the design mechanism of various types of coil, comparing the clinical benefits of braided and cut stents for assisting coil deployment, as well as analyzing the design principle and the optimization direction of currently the most eye-catching flow diverter, and thus the development and application of various interventional devices were discussed.

Arterial aneurysms remain a significant public health problem because they often result in death when ruptured; therefore, they require immediate medical treatment. Endovascular aneurysm repair (EVAR) has recently become the primary treatment option, owing to the fewer side effects compared to those with open surgery. However, stents used for conventional EVAR often cause side-branch occlusion, which alters the perfusion of vital organs.
