Basic Technical Requirements For Balloon Catheters Basic Technical Requirements For Balloon Catheters - Medical Coating - Cheersonic Balloon catheters are divided into balloon dilatation catheters, balloon occlusion catheters and balloon remodeling catheters. Balloon dilatation catheter is a flexible catheter with an inflatable balloon at the head, which is used to dilate narrow hollow organs in the human body under image guidance, such as blood vessels, digestive tract, urinary [...]

Degradable Polymer Occluder Degradable Polymer Occluder - Medical Device Surface Coating - Cheersonic The traditional treatment for congenital heart disease is open thoracic surgery, which can cause severe trauma to the patient. With the development of interventional medicine, there are currently 5 types of occluders on the market for the interventional treatment of congenital or structural heart diseases - atrial septal defect occluder, ventricular septal defect occluder, soft [...]

Coronary Stent Coronary Stent - Medical Device Coating - Cheersonic Coronary heart disease is the abbreviation of coronary atherosclerotic heart disease, which is usually caused by coronary atherosclerosis leading to stenosis or obstruction of the vascular lumen, or myocardial ischemia, hypoxia or necrosis caused by coronary functional changes (spasm). . Coronary stent is an intravascular supporter made of metal or polymer material, which can be sent to the [...]

Different characteristics of PTCA balloon Each company's PTCA balloons have various characteristics, such as balloon size, materials used, construction, and compliance of the balloon to the vessel lumen. Depending on the location and severity of the lesion, PTCA is required to have different properties and characteristics. PTCA balloons are divided into compliant, non-compliant and semi-compliant balloons according to their compliance. Semi-compliant PTCA balloon for pre-dilation of lesions before [...]

Optimizing Second-generation Drug-eluting Stents Optimizing Second-generation Drug-eluting Stents - Spray Coater - Cheersonic In order to solve the problem of late thrombosis risk, after 2006, the second generation of drug-eluting stents embarked on the road of comprehensive optimization, mainly from the three aspects of stent platform, drug and coating. Optimization 1. Optimization of the bracket platform: Nickel-titanium alloy or cobalt-chromium alloy and other alternatives to stainless steel have [...]

3 Key Biomedical Materials 3 Key Biomedical Materials - Ultrasonic Nozzle - Cheersonic Biomedical materials refer to new high-tech materials that can diagnose, treat, repair, replace diseased tissues, and reconstruct organ functions for living organisms. As an interdisciplinary research field of materials and biomedicine, the research and development of biomedical materials is inseparable from the material discipline. The material structure determines the performance, and the performance leads to [...]

Nervous System Intervention Nervous System Intervention - Ultrasonic Atomizing Nozzle - Cheersonic Neurointerventional techniques, as the name suggests, are used to treat neurological diseases. Under the support of digital subtraction angiography (DSA) system, it adopts intravascular catheter operation technology, through selective angiography, embolization, dilatation, mechanical removal, drug delivery and other specific methods to treat lesions involving the human neurovascular system. Diagnose and treat. It is an emerging minimally [...]

Cardiac Interventional Devices Segmentation Cardiac Interventional Devices Segmentation - Ultrasonic Coating Systems - Cheersonic Main research contents of cardiac intervention: Cardiovascular and cerebrovascular interventional treatment devices mainly include coronary stents, distal protectors, vascular closure devices, ASDs, artificial valves and PDA occluders. Cardiovascular disease refers to diseases related to the heart or blood vessels. Usually includes coronary heart disease, cerebrovascular disease/stroke, hypertensive heart disease, rheumatic/rheumatoid heart disease, congenital heart [...]

Interventional Therapy Interventional Therapy - Biocoating - Cheersonic Nozzle Definition of Interventional Therapy Interventional therapy 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 several millimeters in blood vessels and skin without exposing the lesions, or through the original pipes of the human body, in the imaging equipment (angiography machine, fluoroscopy machine, [...]

Preparation Of Coating On Balloon Surface Basic Concepts About Balloons Balloon outer diameter: Refers to the outer diameter of the balloon and distal catheter in the unexpanded state. Coating substances on the surface of the balloon • Hydrophobic coating (Hydro-phobic) is mostly stent balloon. • The hydrophilic coating (Hydro-phylic) enhances the passing ability of the balloon. Dilation pressure (Nominal Pressure): refers to the pressure required to obtain the [...]
