Percutaneous Coronary Intervention
A catheter-based therapy in which a blocked artery is opened using one or several of six different
tools. All are delivered by means of a tube inserted in the femoral artery (at the groin) and advanced
to the mouth of the artery. Following are the tools:
- Compacts plaque to create a larger, approximately normal coronary channel
- Delivering low grade radiation to a treated segment of coronary artery to prevent recurrence of scar formation
- A balloon with micro blades that scores the plaque and relaxes it as it is compacted by the balloon
- A catheter* consisting of aligned optical fibers that delivers colder laser energy to plaque or clot and vaporizes it into CO2 (carbon dioxide) and water
* a catheter is a tube directed into a coronary artery without surgery that then delivers some form of energy to modify or remove plaque.
