PTCA & PTA Balloon Catheter Design and Development

ProXCath Medical is a high-tech medical device company specializing in the research, design, and development of devices that allow for minimally invasive medical procedures. We have over 15 years of experience and are pleased to present our PTCA and PTA balloon catheter design and development.

But first, let’s uncover what they are.

What is a PTCA Balloon Catheter?

A percutaneous transluminal coronary angioplasty (PTCA) is a minimally invasive procedure used to open a blocked coronary artery. The primary goal is to increase blood flow in this blocked vessel. A PTCA balloon catheter is the tubing with a balloon at one end that is used to perform this procedure.

What is PTA Balloon Catheter design?

PTA, which stands for percutaneous transluminal angioplasty, is a minimally invasive medical procedure used to open a clogged blood vessel. The flexible tubing used to perform this procedure to restore blood flow is known as a catheter.

Details and uses of the two devices

These devices are classified into two types: over-the-wire (OTW) and rapid exchange (Rx). The most common one is Rx, which is used on the majority of coronary procedures.

However, this is not to say that OTW are no longer effective as they are the preferred type in highly tortuous blood vessel pathways. They are the best because they give up deflation time and pushability.

They are used during angioplasty procedures to compress plaques within a clogged coronary artery and to deploy stents. They are usually delivered to the cath lab with a stent already attached to the balloon. And the surgeon in charge of the procedure inflates the balloon, causing the stent to expand. When deflated, the stent usually remains behind the artery, allowing the catheter to be easily removed.

These stents are known as balloon-expandable stents. Self-expandable stents, which are typically made of Nitinol alloy, are another type.

Specifications of the two devices

Medical Devices Catheter manufacturing usually makes the OTW about 150cm long with a 300cm wire. The Rx is used with a standard wire ranging between 150-180 cm.

A standard OTW balloon catheter has two lumens that run the length of the catheter. The balloons are typically 145-150 cm long and designed to be used with various sized guard wires.

An OTW has the advantage of maintaining distal artery access with the balloon beyond the lesion while the guard wires are exchanged by the surgeon. The entire system tracks well because the entire length of the balloon has a wire lumen, allowing for lengthy wire guidewire exchanges. After the guidewire has been removed, the cardiologist can use the same system to deliver drugs distally to the artery.

The RX is used to treat the most difficult lesions because of its low tip entry and crossing profiles. The balloon is long and tapered, with a lubricious coating. They also provide improved visibility, allowing for more precise placement during procedures. They are also very pushable with little resistance, and their length helps with distal access.

Bottom line

Both of these devices are created with the utmost precision by the best catheter technology company in medical devices class II & III. However, advancements are constantly being made to improve their functionality. ProXCath is one of the innovators whose goal is to improve the efficiency of these devices.
