Medtronic has recently achieved a significant milestone with the U.S. Food and Drug Administration’s approval of its Affera mapping and ablation system, intended for the treatment of persistent atrial fibrillation (AFib). This new system, which went into effect following a $925 million acquisition of Affera in 2022, features innovative technology that combines both mapping capabilities and a dual-energy catheter. This technology distinguishes it significantly from its predecessor, Medtronic’s Pulseselect, as well as competing systems like Boston Scientific’s Farapulse and Johnson & Johnson’s Varipulse, by offering both radiofrequency (RF) and pulsed field ablation (PFA) energies.
PFA, the latest advancement in cardiac ablation techniques, treats heart arrhythmia by using electrical pulses that cause less damage to surrounding tissues compared to traditional methods that employ heat or cold. Unlike Medtronic’s Pulseselect, which was the first FDA-approved PFA device but lacked mapping and RF capabilities, the Affera system incorporates these features, addressing significant gaps and setting a new standard in the field.
The Affera Sphere-9 catheter, integral to the system, allows toggling between RF and PFA energies and integrates advanced mapping technology. Previously, physicians in need of mapping PFA procedures were generally limited to third-party systems predominantly from Abbott and J&J. This landscape began to shift with the FDA’s recent approvals, first of Boston Scientific’s Farapulse mapping system and shortly after, Medtronic’s Affera system. These approvals suggest an impending transformation in the electrophysiology market, particularly challenging the dominance of Abbott and J&J in RF ablation procedures.
Financial analysts have responded positively, noting Affera as a “meaningful upgrade” over Pulseselect, with a potential significant impact on the market. With the ability to perform point-by-point ablation, Affera is suited for a broader range of cases compared to systems like Farapulse, which is optimized for single-shot, de novo ablation. This versatility could potentially shift the standard treatment approach, leading to varying market shares among competitors. Some analysts and physicians anticipate that as new devices like Affera are introduced into the market, there will be considerable shifts in device use preferences among healthcare providers, with potential implications for product pricing and market share dynamics. Boston Scientific is preparing to counter these developments by presenting new PFA data tailored to persistent AFib populations and advocating the efficiency of their technology.
Despite this competitive landscape, the true market impact of Affera is expected to materialize slowly, with Medtronic projecting a modest contribution to its revenues in the current fiscal year, anticipating a more significant revenue ramp up in fiscal 2026. Medtronic’s CEO, Geoffrey Martha, indicates that while there have been breakthroughs in manufacturing capabilities recently, there is still substantial progress to be made in supply chain and production to fully capitalize on the Affera’s market potential. The complexities of manufacturing these advanced catheters have been highlighted as an ongoing challenge, though Martha suggests that competitor narratives may be influencing this perception.
As the market adapts to these innovations, there is a nuanced set of expectations and strategies among major players and observers alike. The evolving technology and regulatory approvals are set to redefine treatment paradigms and competition in the electrophysiology space, marking a significant leap forward in the management of atrial fibrillation through advanced ablation technologies.
