Introduction:
In the field of peripheral interventional, Percutaneous Transluminal Angioplasty (PTA) with a balloon dilatation catheter has revolutionized the treatment of peripheral vascular diseases. This minimally invasive procedure offers significant advantages over traditional surgical interventions. In this article, we will delve into the details of PTA balloon catheters, exploring their structure,  working mechanism etc in peripheral medicine.

Structure and Design:
PTA balloon dilatation catheters consist of a flexible catheter shaft with an inflatable balloon attached at its distal end. The catheter is typically made of medical-grade polymers, allowing it to be maneuvered through the blood vessels with ease. The balloon is constructed from a material with excellent compliance and strength, such as high-pressure nylon or polyethylene terephthalate (PET).

Working Mechanism:
The primary purpose of a PTA balloon dilatation catheter is to widen narrowed or obstructed blood vessels. Once the catheter reaches the target site, the deflated balloon is positioned precisely within the stenotic segment. Subsequently, the balloon is inflated using a pressurized liquid, typically a mixture of saline and contrast medium.

As the balloon expands, it exerts radial pressure on the vessel wall, compressing the plaque or other obstructions present. This process remodels the vascular lumen, restoring blood flow and improving oxygen delivery to the affected tissues. Once the procedure is completed, the balloon is deflated and withdrawn, leaving the vessel in an improved state.

Kossel’s PTA balloon dilatation catheters have been approval by USFDA and have been used and widely praised in the mainstream markets.We are committing to product improvement and breakthrough, and strive to contribute to human health all over the world.
