Cerebrovascular Stent
Stroke, also known as “stroke”, is an acute cerebrovascular disease, which is divided into ischemic stroke and hemorrhagic stroke, which are often called “cerebral infarction” and “cerebral hemorrhage”. The incidence rate of acute cerebrovascular diseases remains high, seriously threatening people’s healthy life. When a cerebral blood vessel is severely blocked, a stent is usually inserted to widen the narrowed blood vessel and allow blood to flow normally. This is an important means to treat and prevent cerebrovascular disease.
Cerebrovascular stent implantation is a minimally invasive surgery. Under the monitoring of an angiography machine, a catheter, guide wire, and balloon are inserted through the femoral artery or radial artery. Under the action of the catheter, guide wire, and balloon, , the stent is placed in the stenotic part of the blood vessel to expand the narrowed blood vessel and improve the distal blood supply, thereby achieving the purpose of treating and preventing cerebral infarction. Cerebrovascular stent implantation is characterized by less trauma, less pain, and shorter hospitalization time, so it is widely used in the treatment of cerebral artery stenosis.
Indications for carotid artery stenting:
1. The carotid artery stenosis rate is confirmed by imaging examination to be ≥70%.
2. The carotid artery stenosis rate is ≥50% and there is clear ulcer formation and/or unstable plaque.
3. Stenosis of 50%-70%, accompanied by obvious related symptoms such as repeated transient ischemic attacks and a history of ipsilateral cerebral infarction.
4. Restenosis after endarterectomy and stent surgery.
5. Lesions with high surgical risk or that cannot be treated by surgical methods, such as bilateral severe stenosis and tandem stenosis.
6. Arterial dissection caused by spontaneous, traumatic or postoperative conditions.
Indications for intracranial stent implantation:
1. Symptomatic intracranial artery stenosis >60%.
2. The blood vessels distal to the stenosis are normal, the length of the diseased blood vessels in the posterior circulation is <20mm, and the length of the diseased blood vessels in the anterior circulation is <15mm.
3. Residual stenosis after acute arterial thrombolysis and thrombectomy.
4. Recurrent clinical symptoms and neurological dysfunction consistent with narrowed blood vessel supply areas.
Of course, doctors must make optimal choices based on the patient’s condition and specific problems during clinical operations.
UMC7100 Ultrasonic Balloon Catheter Coating Machine is designed for drug eluting balloons. It provides a uniform drug coating for the balloon catheter through ultrasonic spray technology. UMC7100 can also be used to adjust and control the deposition process of drug coatings for different liquid formulations. With the help of a special fixing device design, the entire balloon catheter can be sprayed with a maximum spraying length of 280 mm., It also has the functions of solvent doping, pre-heating, humidity control, and drying. The equipment has the characteristics of precise application amount, uniform film layer, and high utilization rate of chemical liquid. Cheersonic has extensive experience in surface coating of implantable medical devices (such as drug stents and balloons), and can provide customers with complete solutions.
