What manufacturing process is used for the making catheters?

What manufacturing process is used for the making catheters?

A long, thin tube is made by pouring the raw material into a room temperature vulcanization (RTV) mold, which is in the desired shape and diameter of the catheter. The material is then cured with heat for a duration of 0.5 to 40 hours. Once it is cool, the tube is pulled out from the mold.

What is PTCA catheter?

A PTCA catheter is a device that operates on the principle of hydraulic pressurization applied through an inflatable balloon attached to the distal end. A PTCA balloon catheter has a single or double lumen shaft.

What are balloon catheters made of?

Compliant (elastomeric) balloons are typically made of polyurethane or silicone. They are inflated by volume, rather than pressure. Able to stretch 100% to 800%, they are often used in applications that require the balloon to fully conform to or occlude the anatomy.

What is rapid exchange catheter?

The Rapid Exchange balloon catheter (RX) Xperience, is designed for percutaneous transluminal angioplasty of coronary arteries. The shaft of the catheter features a combination of a single lumen at the proximal end and double lumen at the distal end:

What are the types of urinary catheter?

What are the types of urinary catheters? There are three main types of catheters: indwelling catheters, external catheters, and short-term catheters.

How is PTCA done?

PTCA, or percutaneous transluminal coronary angioplasty, is a minimally invasive procedure that opens blocked coronary arteries to improve blood flow to the heart muscle. First, a local anesthesia numbs the groin area. Then, the doctor puts a needle into the femoral artery, the artery that runs down the leg.

Why is a PTCA done?

Percutaneous transluminal coronary angioplasty (PTCA) is performed to open blocked coronary arteries caused by coronary artery disease (CAD) and to restore arterial blood flow to the heart tissue without open-heart surgery.

Are called balloon catheter?

: a catheter with an inflatable tip which can be expanded (as by air or water) especially to hold the catheter in place or to expand a partly closed or obstructed bodily passage, opening, or vessel (such as a coronary artery) — called also balloon-tipped catheter. — see balloon angioplasty.

What does PTCA stand for in cardiology?

PTCA Abbreviation for percutaneous transluminal coronary angioplasty. Angioplasty performed to open a narrowed coronary artery, in which a balloon-tipped catheter is inserted into an artery in the groin or shoulder and threaded to the affected part.

What is the purpose of PTCA?

PTCA is used to treat coronary artery disease, which may manifest as traveling pain and discomfort in the chest.

What is the PTCA balloon catheter made from?

A PTCA balloon catheter has a single or double lumen shaft. The catheter features a balloon of appropriate compliance for the clinical application, constructed from a polymer.
