Applications of Heparin Lithium Coating

Applications of Heparin Lithium Coating – Cheersonic

1. Cardiovascular Interventional Field
Coronary Interventional Treatment (PCI): In PCI, the guidewire is a crucial instrument guiding the balloon catheter and stent to the narrowed coronary artery. Coating the guidewire with heparin lithium effectively prevents blood from clotting and forming thrombi. Because coronary arteries are small and have high blood flow rates, thrombus formation can lead to vascular blockage and serious complications such as myocardial infarction. The heparin lithium coating, through its anticoagulant properties, reduces this risk and improves the safety of the procedure.

Pacemaker Implantation: During pacemaker implantation, the electrode leads need to be inserted into the heart through blood vessels. During this process, the heparin lithium coating prevents blood from clotting on the lead surface, ensuring successful placement and reducing postoperative complications such as electrode dysfunction and infection due to thrombosis.

2. Angiography and Intravascular Ultrasound

Angiography: During angiography, an angiography catheter needs to be inserted through a blood vessel to the target site. Coating the catheter and guidewire with heparin lithium can prevent blood clotting from affecting the angiographic results. Because blood clotting can block catheters, preventing the smooth injection of contrast agents or affecting image quality, making it difficult for doctors to accurately assess vascular lesions.

Intravascular ultrasound: The use of a lithium heparin coating on the guidewire of intravascular ultrasound equipment also prevents thrombosis, ensuring the ultrasound probe can move smoothly within the blood vessel, obtaining clear and accurate information on the vessel wall structure and lesions, providing a reliable basis for diagnosing vascular diseases.

3. Hemodialysis Field

Dialysis Catheters: In hemodialysis, dialysis catheters are crucial channels connecting the patient’s blood vessels and the dialysis equipment. The lithium heparin coating on the catheter surface prevents blood clotting within the catheter, ensuring smooth blood flow during dialysis. Blood clotting in the dialysis catheter can reduce dialysis efficiency or even interrupt dialysis, threatening the patient’s life and health.

4. Extracorporeal Circulation Equipment

Oxygenators and Tubing: In extracorporeal circulation surgeries (such as coronary artery bypass grafting), blood needs to flow within extracorporeal circulation equipment (such as oxygenators and various tubing). The heparin lithium coating on these devices reduces blood clotting upon contact with the device surface, ensuring smooth extracorporeal circulation and lowering the risk of serious complications such as organ ischemia and hypoxia caused by thrombosis.

5. Neurovascular Interventional Field
Cerebrovascular Interventional Therapy: In cerebrovascular interventional surgeries (such as intracranial aneurysm embolization and endovascular treatment of acute ischemic stroke), guidewires and catheters need to be operated on in delicate and tortuous cerebral blood vessels. The heparin lithium coating prevents blood clotting, reduces thrombosis damage to cerebral blood vessels, and improves the success rate of the surgery and patient prognosis. This is because cerebral vascular occlusion can lead to severe brain damage, such as cerebral infarction.
