Cardiovascular is one of the largest and most durable segments in medical devices, and for the people who sell in it, one of the most rewarding. The work happens in the cath lab and the structural-heart suite, on some of the highest-stakes cases in medicine.
Here are the companies that lead cardiovascular devices, and, drawing on years in structural heart, what it is actually like to sell among them.
Why is cardiovascular such a large device market?
Cardiovascular is broad by nature. It spans cardiac rhythm management, meaning pacemakers and defibrillators, structural heart, meaning replacement valves and closure devices, electrophysiology, meaning mapping and ablation, and vascular disease, meaning stents and clot removal. Each is a substantial market on its own.
It is also riding real tailwinds. An aging population, a large unmet clinical need, and a wave of minimally invasive structural-heart therapies keep the field growing, which is part of why it is such a good place to build a career.
Who are the leading cardiovascular device companies?
A few names anchor the category:
- Medtronic runs the largest cardiovascular business in devices, near $14 billion a year, spanning cardiac rhythm and heart failure (about $7.5 billion), structural heart and aortic, and coronary and peripheral vascular. Its franchises include Micra leadless pacemakers, Evolut TAVR valves, and pulsed field ablation.
- Abbott is a cardiovascular powerhouse across electrophysiology (about $2.8 billion), rhythm management with Aveir leadless pacemakers, vascular (about $3.0 billion), and structural heart (about $2.5 billion) with MitraClip, TriClip, and the Amulet left atrial appendage closure device.
- Boston Scientific is a structural-heart and electrophysiology leader, and the maker of the Watchman FLX, the market-leading device for left atrial appendage closure.
- Stryker entered clot removal in a big way with its 2025 acquisition of Inari Medical, pushing its vascular business to about $2.0 billion.
Between them, these companies cover rhythm, structural heart, EP, and vascular, the four pillars of the cardiovascular field.
What is it like to sell in the cath lab?
It is some of the most clinical, highest-acuity selling in the industry, and it does not feel like a typical sale. In structural heart, the rep or clinical specialist is the expert in the room, guiding the physician through a live implant. Take left atrial appendage closure, where a Watchman or Amulet seals off the appendage to prevent stroke in atrial fibrillation patients: roughly 90 percent of strokes in non-valvular AFib start with a clot there, so a good procedure genuinely prevents a catastrophic event. You go home knowing you made an impact.
That clinical depth is also what makes the work valuable. This is not a commodity driven by price; it is a clinical sale where interpreting imaging, sizing a device, and troubleshooting live create a real moat around your expertise. Having two strong competitors in a space, Boston Scientific and Abbott in appendage closure, only raises the value of a specialist who knows the anatomy and owns the relationships.
How do you break into cardiovascular sales?
Cardiovascular is rarely a first job, because the clinical bar is high. The most common way in is through a clinical or field-support role: cardiac sonographers, cath lab nurses, and pacing, EP, or structural-heart specialists all transition into these roles and then into selling.
The reps who thrive invest heavily in the clinical science, because credibility with cardiologists and electrophysiologists is earned through competence in the room. It is demanding, but it pays well, it grows, and few fields let you feel your impact as directly.
Key Takeaways
- Cardiovascular spans rhythm management, structural heart, electrophysiology, and vascular, one of the largest device segments.
- Medtronic leads near $14 billion; Abbott and Boston Scientific are structural-heart and EP powers; Stryker entered clot removal via Inari.
- Boston Scientific's Watchman leads left atrial appendage closure; Abbott's Amulet is the main competitor.
- Cath lab and structural-heart selling is a clinical sale, not a commodity, which makes deep expertise a career-long moat.
- Most reps enter through clinical or field-support roles and invest heavily in the clinical science.
Frequently Asked Questions
What are the largest cardiovascular device companies?
Medtronic runs the largest cardiovascular device business, near $14 billion a year across rhythm management, structural heart, and vascular. Abbott and Boston Scientific are major structural-heart and electrophysiology players, and Stryker recently entered clot removal through its Inari acquisition.
What is structural heart in medical device sales?
Structural heart covers minimally invasive, transcatheter treatments for the heart's valves and chambers, such as replacement aortic valves (TAVR), mitral repair (MitraClip), and left atrial appendage closure (Watchman, Amulet). It is one of the most clinical and fastest-growing corners of cardiovascular devices.
Is cardiovascular sales a good career?
For the clinically inclined, yes. Cardiovascular is large, durable, and innovation-heavy, and cardiac lines tend to pay above the general rep market. The trade is that it is highly technical, high-acuity selling, often supporting live procedures in the cath lab, which demands real clinical fluency.
How do you get into cardiovascular device sales?
It is rarely a first job because the clinical bar is high. Most people enter through a clinical or field-support role, such as a cardiac sonographer, cath lab nurse, or pacing, EP, or structural-heart specialist, and then move into selling after building clinical credibility.
