Baylis Medical Company

What Baylis Medical Company does

Baylis Medical Company is a Montréal-based medical device company founded in 1986 that specializes in high-technology cardiology, endovascular, and oncology products. Its core competency is transseptal access devices and steerable sheath technology used in minimally invasive cardiac electrophysiology procedures, including atrial fibrillation ablation and structural heart interventions. The company's proprietary technology enables precise catheter navigation through transseptal puncture to access the left atrium, a critical step in advanced EP and structural heart procedures.

Baylis Medical generated revenue through direct B2B sales of specialized catheters and access devices to hospitals and electrophysiology labs performing cardiac ablation and structural heart procedures. The company operated with 501–1,000 employees and was identified as a key player in the global steerable sheath market, valued at approximately $0.94 billion in 2025 with a projected 7.34% CAGR to $1.78 billion by 2034. It also operated within the broader $6.7 billion global electrophysiology market, which was forecast to grow at approximately 12% CAGR. Pricing was handled through quote-based contracts with healthcare institutions; no public pricing was disclosed.

In 2021, Baylis Medical was acquired by Boston Scientific as part of Boston Scientific's broader strategy to expand its electrophysiology portfolio—an effort that also included the acquisition of Farapulse. Following the acquisition, Baylis Medical's transseptal access and steerable sheath technology was integrated into Boston Scientific's product offerings, gaining access to the acquirer's global medical device distribution network. As a result, Baylis Medical no longer operates as an independent entity; its products are commercialized as part of Boston Scientific's electrophysiology portfolio.

Broad incumbents

• Boston Scientific: Baylis Medical's parent company and a global medtech leader. Boston Scientific is a direct competitor in steerable sheaths and EP, and now integrates Baylis's transseptal access technology into its broader cardiac portfolio alongside ablation and mapping systems.
• Abbott: Named alongside Baylis as a key player in the global steerable sheath market. Abbott has a broad cardiac and EP portfolio including ablation catheters, mapping, and cardiac devices, competing head-to-head with Baylis's transseptal access technology.
• Medtronic: Identified as a key player in the steerable sheath market alongside Baylis. Medtronic's cardiac rhythm and EP business offers ablation, cryoablation, and mapping systems that compete with Baylis's procedural enablement tools.
• Stryker: Named as a key player in the steerable sheath market alongside Baylis. Stryker operates broadly across multiple medtech verticals and competes with Baylis's transseptal access technology through its interventional and cardiac procedural portfolios.

Direct peers

• Biosense Webster (Johnson & Johnson MedTech): The global leader in electrophysiology with a comprehensive portfolio of ablation catheters, 3D mapping (CARTO), and steerable sheaths. Directly competes with Baylis in transseptal access and steerable sheath technology used in EP ablation procedures.
• AtriCure: Specializes in atrial fibrillation and left atrial appendage management products. Operates in the same cardiac EP and left-atrial procedure space where Baylis's transseptal access technology is used, addressing adjacent steps in the ablation workflow.
• Merit Medical Systems: Manufacturer of vascular access and procedural devices including sheaths and guidewires. Directly comparable to Baylis in steerable sheath and vascular access product categories used across interventional cardiology and EP.
• Teleflex: Produces interventional and vascular access devices including specialty catheters and sheaths. Competes with Baylis in steerable sheath technology and other access products used in cardiac and vascular procedures.

Emerging players

• Stereotaxis: Developer of robotic magnetic navigation systems for EP ablation. Competes in the same EP ablation workflow where Baylis's steerable sheaths are used, offering an alternative approach to catheter navigation that could displace or complement manual steerable sheaths.
• Acutus Medical: EP-focused company developing mapping and ablation technologies for arrhythmia treatment. Overlaps with Baylis at the EP procedure workflow level, particularly in tools that interface with transseptal access and ablation catheter navigation.
