Doença Arterial Coronária e Intervenções Cardíacas

A DES is a metallic coronary stent coated with anti-proliferative drug preventing neointimal hyperplasia and restenosis after PCI. INVAMED ATLAS DES uses a thin-strut cobalt-chromium platform with polymer-based drug delivery.

Rotational atherectomy is indicated for heavily calcified coronary lesions that cannot be crossed or dilated with standard balloons. TemREN diamond-coated burrs ablate calcified plaque while preserving elastic tissue.

A guide extension catheter telescopes through the guiding catheter to provide deep-vessel backup support, extending reach into distal, tortuous, or calcified segments. Essential for complex PCI.

A DEB delivers drug to the vessel wall during inflation without leaving a permanent implant. Primary use: in-stent restenosis treatment and small vessel disease where stent placement is undesirable.
