Medtronic has unveiled three new additions to its coronary portfolio — a transradial diagnostic catheter and accompanying transradial devices to facilitate the treatment of coronary artery disease via the radial artery in the wrist.

Percutaneous coronary intervention, or PCI, is a nonsurgical procedure to treat the narrowing of coronary arteries. While PCI usually involves balloon angioplasty to compress plaque against the wall of the artery, the physician may also deploy a stent to keep the artery open. It is usually done through the femoral artery or the radial artery.
