Boston Scientific

Boston Scientific is based in Marlborough, Massachusetts. Watchman is implanted to close the left atrial appendage in patients who cannot stay on anticoagulants, and Abbott's Amplatzer Amulet is the device cardiologists compare it with.

Farapulse is a pulsed-field ablation console and catheter for atrial fibrillation, competing with Medtronic's PulseSelect and with Johnson & Johnson's electrophysiology franchise. The console is a capital purchase, and the catheters are the repeat spend once physicians are trained on that waveform.

Group purchasing organizations such as Vizient and Premier negotiate device access, but the implanting physician still drives the brand. A hospital that credentials doctors on one ablation system tends to keep the matching generator in the lab.

Watchman and Amulet compete for a limited number of structural-heart lab slots.

Farapulse generators pull a stream of single-use catheters from the same vendor.

GPO contracts set price corridors, while physician preference sets the brand that is actually opened.

Patients are scheduled into whichever lab their cardiologist has trained on, not into an abstract device market.

Hospital supply-chain teams live with both the capital invoice and the catheter reorder.
