Problems solved by technology

Ischemic lesions of the lower extremities are characterized by calcification and elongated lesions. When balloon dilation is used for treatment, due to the poor push performance and low compressive strength of the existing balloon dilation catheter, it is difficult for the balloon dilation catheter to pass through the calcification. Lesions and long-term occluded blood vessels, which make it impossible to complete relevant surgical treatment

Abstract

The invention discloses a balloon dilatation catheter which comprises a pushing tube, an inner tube and a balloon, the inner tube is arranged at the far end of the pushing tube, and the outer surface of the inner tube is sleeved with the balloon; wherein the pushing tube is formed by blending and extruding polylaurolactam and polyether block polyamide. The pushing tube of the balloon dilatation catheter has reliable supporting performance and good flexibility and can penetrate tortuous blood vessels, calcified blood vessels and long-section occluded blood vessels, and the use performance is improved.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, and more particularly to a balloon expansion catheter. Background technique [0002] Since 1977, the success of the intracardiacular diaphragm forming (PTCA) has become the beginning of interventional treatment. In the past four decades, especially in the last decade, the interventional treatment has developed rapidly, and the intervention treatment from the initial Coronary is developed to almost all blood vessels. Interventional treatment has less bleeding, small trauma, less complications, fast postoperative recovery, safe and reliable, etc., greatly reduces the pain of patients. Balloon dilatation is a common interventional treatment, which can be used to expand narrow vascular. [0003] In recent years, with the intensification of my population, elderly patients have increasing the ischemia of lower extremity due to lower extremity arteriosclerosis. The lert ischemia has the chara...
