AI Technical Summary

⚠Technical Problem

In existing technologies, rotational atherectomy or intravascular lithotripsy alone is insufficient to effectively treat complex calcified lesions, especially those with both superficial dense calcification and deep circumferential calcification. This requires multiple instrument exchanges, prolonging the operation time, increasing the complexity of the procedure, and raising patient risks.

⚗Method used

A shockwave rotational atherectomy catheter is designed to integrate rotational atherectomy and shockwave functions into a single catheter, including a rotational atherectomy component, forward and lateral shockwave chamber components, and a balloon component. The functional flow paths are separated by a partition layer to achieve physical isolation and simplify the surgical procedure.

🎯Benefits of technology

It enables thorough and safe treatment of complex calcified lesions, reduces surgical time and costs, lowers the risk of vascular injury, and improves ease of operation.
