AI Technical Summary

Technical Problem

Existing balloon catheters have limited functionality and cannot achieve precise positioning and effect assessment in interventional procedures, resulting in cumbersome operation and large amounts of contrast agent used, which increases the burden on patients' renal function.

Method used

A perfusion balloon dilation catheter system is designed, which integrates a catheter tip image acquisition module, a support wire tip image acquisition module, and a support wire tactile acquisition module to achieve the integration of balloon dilation and angiography functions. The angiography image is acquired through the catheter tip to confirm the position, and the morphology of the support wire and blood vessel is monitored in real time. The support force is adjusted to ensure safety and accuracy.

Benefits of technology

This technology enables precise positioning and efficacy assessment of the balloon dilation catheter at the lesion site, reduces the amount of contrast agent used, lowers the burden on the patient's renal function, and improves the safety and success rate of the procedure.

Abstract

This invention relates to the field of dilation catheter technology, and more particularly to an infusion balloon dilation catheter system, comprising an infusion balloon dilation catheter assembly, which includes a catheter hub, a stress-relieving tube, an outer tube, a balloon, and a tip tube connected in sequence; a catheter tip vascular image acquisition module, used to determine whether the balloon catheter is within the true lumen of the blood vessel; a support wire tip image acquisition module, used to acquire an image of the support wire morphology and the corresponding vascular morphology under X-ray fluoroscopy; and a support wire tactile sensing module, used to acquire the force changes, support wire morphology image, and corresponding vascular morphology image during support wire advancement to determine whether the support wire support force is adequate, and to adjust the support wire posture when the support wire support force is insufficient. The infusion balloon dilation catheter system of this invention simultaneously possesses balloon dilation and angiography functions, and utilizes image and data processing technology to improve the intelligence level of medical devices.
