Main Points of Manufacturing Small Caliber Artificial Blood Vessels Small-bore vascular grafts perform poorly clinically, mainly due to the development of intimal hyperplasia and thrombus formation. To overcome these challenges, various design approaches, material selection, and surface modification strategies have been employed to improve the patency of small-diameter grafts. These include material selection, surface modification to enhance biocompatibility/endothelialization, and mechanical properties of the grafts currently being implanted. An [...]

Medical Conveyor Polymer Materials In minimally invasive interventional medical devices, stents and covered stents are commonly used. These devices and conveyors constitute a complete interventional medical device. After the transporter is transported, it has to complete the disposal process of withdrawing from the body after placement, so it is usually a disposable appliance. Even so, the performance of the conveyor will directly affect the smoothness of the operation [...]

Implantable Polymer Materials In minimally invasive interventional therapy devices, polymer materials can be used to meet the needs of carriers that need controlled release systems, such as covered stents, embolic agents, biodegradable stents and therapeutic drugs. Such devices usually coexist with the human body for a long time after implantation. Therefore, the polymer materials used shall ensure good antithrombotic property, excellent compatibility, stable physical and chemical properties and [...]

Artificial Blood Vessel Manufacturing Process To date, most of the manufacturing methods used for artificial blood vessels are as follows: Electrospinning is one of the versatile methods used by tissue engineers to fabricate degradable scaffolds because it is compatible with many polymers and customizable enough to create vascular conduits with optimized properties. The process converts polymers dissolved in volatile solvents into nano- and microfibers in the application of [...]

Minimally Invasive Interventional Medicine Minimally invasive interventional medicine is an emerging medical technology that uses a series of interventional equipment and modern equipment to reach the lesion in the body, so as to achieve the effect of minimally invasive treatment. Different from traditional surgical operations, it has the advantages of only local anesthesia, small trauma, high safety factor, and fast postoperative recovery, which greatly reduces the pain of [...]

Medical Intervention Catheter Vascular interventional catheters are high-value consumables commonly used in doctors' operations. A thin catheter can help the surgeon solve problems. With the continuous development of science and technology, and the continuous improvement of product performance requirements of patients for medical devices, various factors promote the continuous change of production materials for vascular interventional catheters. How did the materials for vascular interventional catheters develop? This needs [...]

Electrospun Fiber Electrospun fibers shine in the fields of orthopedics and artificial vascular stents Why Choose Electrospinning Technology With the development of nanotechnology and the emergence of polymer materials, synthetic nanofibers are gradually known and widely used in catalysis, energy, biomedicine and other fields. Among the many preparation methods of synthetic nanofibers, electrospinning has become one of the best choices due to its simplicity, quickness, cost-effectiveness and high [...]

Definition of Interventional Therapy 1. Definition of Interventional Therapy Interventional treatment is an emerging treatment method between surgery and medical treatment. To put it simply, interventional therapy is to make tiny channels with a diameter of a few millimeters on blood vessels and skin without exposing the lesion by surgery, or through the original pipeline of the human body, in the imaging equipment (angiography machine, fluoroscopy machine, CT, [...]

Surface Antibacterial Functional Coating In recent years, with the frequent use of biomedical materials, the problem of iatrogenic infection caused by pathogenic bacteria adhering to the surface of medical devices or implant biomaterials has become one of the biggest hidden dangers to the health of patients worldwide, seriously endangering Social public health security. Therefore, designing an effective method to construct a surface coating with antibacterial function has important [...]

Neural Microwire Neural Microwire - Medical Device Coatings - Cheersonic It is well known that guide wire plays a very important role in the diagnosis and treatment of cerebrovascular diseases. A good guide wire can make the operation more effective, and a poor guide wire can drive the surgeon crazy. The blood vessels in the brain are not only thin but also tortuous, and the requirements for the [...]
