Medical Balloon Catheters: What Are Some Key Design Considerations?

Medical balloon catheters can be used to carry out a variety of invasive diagnostic and medical procedures, including balloon dilation to expand blood vessels and open up obstructions and also providing stents, as well as others.

It is possible to consider a myriad of elements to be considered when designing balloon catheters, including the balloon's use, the type of balloon used, the design of the catheter, as well as performance requirements. You can find more information about medicative balloon design online.

Applications

The intention behind why the catheter is used is the most important reason for designing the catheter. The most frequent uses for balloon catheters are Renal denervation, Cryoablation, Balloon sinuplasty, and Transcatheter aortic valve placement (TAVI).

Medical Balloons Types:

The two principal types that balloons can be found:

Uncompliant (high-pressure) balloons typically consist of polyester or nylon. They're utilized for situations when the balloon has to be inflated to a specified diameter, then apply massive pressure to eliminate an obstruction or dilate the vasculature.

Semicompliant (mid-pressure) balloons are generally comprised of Pebax or more robust polyurethanes. They're utilized for situations that require moderate-to-high pressures but need greater compliance than a balloon that is not compliant, as well as more flexibility to deliver.

Catheter types:

Otw (OTW) balloon catheters feature an extended guidewire which is a continuous length that the catheter is.

Balloon catheters that are RX rapidly exchange (RX) balloon catheters come with an extended guidewire that extends along a small segment (about 25cm) and can cut downtime compared to moving guidewires along the entire longest length.
