Problems solved by technology

In use, the characteristics of the smooth and flat surface lead to the disadvantages that the amount of drug in the coating is small and it is easy to fall off during the process of advancing, expanding and rubbing against the blood vessel wall

Embodiment Construction

[0022] The surface strip balloon catheter as shown in the figure is a creative improvement to the existing percutaneous transluminal angioplasty and percutaneous transluminal coronary angioplasty balloon catheters.

[0023] This surface strip-shaped balloon catheter includes a guide wire 11, an inner catheter 12, an outer catheter 13, a balloon body A, a strip-shaped bulge 14, a concave groove 15 and a drug coating 16, and is characterized in that:

[0024] The upper surface of the balloon A is a cavity-shaped balloon formed by alternately arranging strip-shaped protrusions 14 and concave-shaped ravines 15 .

[0025] The two ends of the above-mentioned balloon body A are respectively fixed on the outer catheter 13 which is divided into two sections.

[0026] The number of strip-shaped protrusions 14 on the balloon body A is 2-80.

[0027] The strip-shaped bulges 14 and concave-shaped ravines 15 of the balloon A are strip-shaped distributed in the same direction as the axis of...

Abstract

The invention relates to a catheter with a strip saccule on the surface, which comprises a guide wire (11), an inner catheter (12), an outer catheter (13), a saccule body (A), strip bulges (14), concave channels (15) and a medicament coating (16), and is characterized in that: the surface of the outer catheter is provided with the saccule body formed by arranging and combining the strip bulges (14) and the concave channels (15) at intervals. The catheter with the strip saccule on the surface can carry more medicaments, ensures that the medicaments are difficult to fall off in the process of advancing, expanding and rubbing a vascular wall because the vascular wall is difficult to contact and rub the medicaments in the pits and concave channels on the surface, and can effectively improve treatment efficiency.

Description

technical field [0001] The invention relates to a surface-coated drug balloon catheter, in particular to a strip-shaped balloon catheter, which is suitable for percutaneous intraluminal angioplasty and percutaneous intraluminal coronary angioplasty. Background technique [0002] Balloon catheter is a tool for endovascular angioplasty, which has been widely used in clinical medicine of percutaneous transluminal angioplasty and percutaneous transluminal coronary angioplasty. Under the guidance of medical imaging equipment, it uses percutaneous puncture technology to insert the balloon catheter into the narrow part of the blood vessel, and expands the balloon under strict monitoring to expand the narrow part of the blood vessel, so as to restore the diameter of the lumen, The purpose of speeding up blood circulation. The existing balloon body is an inflatable complete balloon body arranged at the distal end of the catheter and surrounding the guide wire, and the smooth and fla...
