Interventional Cardiology

Whether designing and producing a stent delivery system or balloon catheters, Quasar Medical’s streamlined assembly and automated processes deliver customized solutions for every project. Through strong partnerships with our clients, we ensure that manufacturing technology and capacity are never an obstacle to the success of your device. Our engineering services ensure a design-for-manufacturability (DFM) approach, keeping production efficiencies and cost reductions in mind with every product.

Applications of Interventional Cardiology

  • Cardiac catheterization: A diagnostic test for determining the presence of plaque, the strength of heart muscles, and heart valve functioning.
  • Percutaneous coronary intervention (PCI): Technique used for restoring blood flow through an artery.
  • Atherectomy: Hardened blockages are removed using various tools during catheterization; stenting may also be done.
  • Patent foramen Ovale Closure: An innovative catheter-based procedure that can replace open-heart surgery in infants.

Coronary artery diseases stem from a number of causative factors. Those who have developed a coronary artery disease tend to choose non-invasive or minimally invasive treatment methods that fall under the umbrella of interventional cardiology (IC). IC basically involves the use of catheters in the diagnosis and treatment of various coronary artery diseases: angina, arrhythmias, myocardial infarction (heart attack), and many more.  Such minimally invasive procedures significantly reduce patient risk while ensuring precise delivery of the  treatment within the heart. 

Open-heart procedures, on the other hand, are much harder to recover from and can cause issues with other healthy parts within the body and the heart. The catheter is a narrow tube, with a diameter as small as1/10th that of a human hair, capable of carrying and delivering medical treatments to the heart. When an artery has been narrowed or blocked, a balloon catheter is commonly used. This is known as angioplasty (a.k.a., percutaneous transluminal angioplasty or balloon angioplasty). 

Catheters may also have a sheath for protection; a drug-delivery tip for delivering contrast dyes or medicines within the artery; a balloon that can be precisely controlled by the interventional cardiologist; or carry bio-sensors for determining blood flow, pressure, temperature, and the internal anatomy of the arteries. Balloon catheters can even be used to deliver and place a stent in the affected vessel following an abrasive procedure (atherectomy). Precise control over the functioning of the balloon and a pulverizing tip—to remove plaque, deliver drugs, perform imaging, etc.—is mandated for any good IC device brand. During an IC procedure, if a balloon tip takes too long to expand or a catheter tube is not flexible enough to travel without friction through the blood vessel from the leg to the heart, it can cause undue discomfort or even injury.

The design, materials used in production, and quality of the catheter and its balloon tip are therefore critical to the success of the interventional cardiology procedure. The higher the quality and precision of a device, the  more an OEM will be seen as a superior brand in the market.

When looking for medical device manufacturers in the field of interventional cardiology, the following features such as: 

  • Expertise in new product design & development 
  • Rapid overall turn-around (from design to delivery)
  • Cost-effective end-to-end manufacturing, including clean rooms, breakthrough technology for production (e.g., molding, assembly, tubing, and staging multiple-QC testing points), and packaging 
  • A resilient supply chain (from receiving supply materials to delivering finished products to clients on time, even in times of crisis situations like COVID-19)
  • Complete multi-layer intellectual property (IP) protection 
  • Global production standards

Quasar is your end-to-end medical device manufacturing solution with 30 plus years of medical device design and manufacturing expertise.
