Shockwave balloon catheters help advance coronary interventional techniques to a new level.

Intravascular shockwave lithotripsy (IVS) is an innovative technology developed based on the lithotripsy concept used to treat urinary tract stones, combined with balloon angioplasty. It selectively targets calcified lesions in the intima and submedullary media using acoustic pressure waves generated by pulses within the balloon, loosening the calcifications without affecting the integrity of the vascular intima. This achieves plaque modification, expands the lumen area, and provides conditions for subsequent stent placement and full expansion. It also overcomes the shortcomings of residual stenosis and ineffective fragmentation of calcified rings after coronary rotational atherectomy. It is hailed as another major "godsend" for patients with coronary artery calcification, helping them regain a healthy heart.

A reporter learned from a top-tier hospital in Guangdong Province that the hospital successfully completed a procedure using a Vesscrack shockwave balloon catheter and a drug-eluting balloon to treat in-stent restenosis. The patient, over 80 years old, sought medical attention due to recurrent chest tightness and chest pain. After a thorough examination, doctors discovered that the patient had multiple vessel lesions, requiring interventional surgery. One segment involved in-stent restenosis with severe calcification. Following extensive communication and analysis of the patient's condition, the professional team ultimately utilized a combined Vesscrack shockwave balloon catheter and drug-eluting balloon to treat the in-stent restenosis and severe calcification. Post-operatively, the patient's blood flow recovered well, and the surgery achieved satisfactory results.

With the development of science and technology and strong policy support in my country, high-tech breakthroughs in the medical field are constantly emerging, with numerous innovative achievements. The advent of several new cardiovascular coronary intervention products, such as bioresorbable stents, cutting balloons, and shockwave balloons, has benefited more patients with coronary heart disease, while also helping to overcome the technological bottlenecks imposed by foreign countries and accelerating the localization of high-end medical devices in my country. It is believed that in the future, more excellent domestic brands will "stand out" on the international stage, using "Made in China" to benefit more patients worldwide.
