What CIRCA Scientific does
CIRCA Scientific, Inc. is a privately held medical device company founded in 2009 and headquartered in Englewood, Colorado, that develops and commercializes cardiac access and monitoring technologies for electrophysiologists and interventional cardiologists. The company operates three product franchises: esophageal temperature monitoring probes (S-CATH, S-CATH M, MATRIX12 M) connected to the CIRCA Temperature Monitoring System, the CrossWise RF Transseptal Access System, and the PeriCross Epicardial Access Kit. Core technology centers on proprietary multi-sensor probe designs with 12 thermistor sensors on PEBAX-coated flex-circuits (GaplessGrid) for rapid edge-to-edge esophageal temperature detection, tine-based epicardial capture mechanisms, and zero-exchange RF transseptal cannulas compatible with major sheaths and 3D mapping systems (CARTO, EnSite X). All major products are FDA 510(k) cleared and protected by an extensive US patent portfolio spanning the S-CATH, MATRIX12, CardioCurve, CrossWise, and PeriCross families.
The company generates revenue primarily through hardware sales of proprietary single-use cardiac devices to hospitals, EP labs, and cardiac catheterization labs, complemented by recurring accessories (interconnect cables, mapping cables, temperature standards). Pricing is quote-based and contract-driven, with GPO agreements in place with Premier, Vizient, and MAGNET Group covering thousands of US healthcare facilities. GTM is hybrid: a 40+ US independent representative field-sales force targeting top EP programs and academic medical centers, augmented by international distributors for OUS markets. Marketing is anchored at major electrophysiology conferences (HRS, VT Symposium, AF Symposium) and peer-reviewed clinical publications. CIRCA has supported over 400,000 AF ablation procedures in more than 300 US hospitals and is trusted by the top 5 US EP programs. Leadership includes experienced medical device operators (CEO Lee Geist, CCO David Smith, CFO Bryan Grulke of Volcano Capital), and a $16M private placement was initiated in September 2024 to fund commercial scaling of the CrossWise and PeriCross platforms.

CIRCA Scientific competitors and assessment
Company assessmentDirect peers
- Boston Scientific: Boston Scientific is the largest direct competitor to CIRCA across multiple product lines: owns the FARADRIVE steerable sheath (with which CIRCA's CrossWise is compatible but competes against), acquired Baylis Medical's transseptal platform for $1.75B in 2022 (NRG RF transseptal needle and VersaCross), and acquired Advanced Cardiac Therapeutics which had thermal sensing ablation catheter technology. BSC serves the same electrophysiologist and interventional cardiologist customers.
- AtriCure: AtriCure is the leading competitor in epicardial and surgical ablation, directly competing against CIRCA's PeriCross Epicardial Access Kit. AtriCure's cryoICE and Isolator Synergy tools are used in the same VT ablation procedures where PeriCross provides pericardial access. Both companies target interventional cardiologists and electrophysiologists performing complex ablations.
- Abbott: Abbott is a major EP player whose EnSite X 3D cardiac mapping system integrates with CIRCA's MATRIX12 M (both display the probe on mapping). Abbott also sells ablation catheters and sheaths that compete in the same EP lab workflow. Both target electrophysiologists performing AF ablation procedures.
- Biosense Webster (Johnson & Johnson): Biosense Webster is the largest EP-focused medical device company globally. Its CARTO 3D mapping system and VIZIGO steerable sheath are both mentioned as integration points and competitors for CIRCA products. Biosense Webster's ThermoCool catheters and CARTO mapping platform dominate the EP lab where CIRCA's tools are used.
- Pressure Products: Pressure Products manufactures the SafeSept needle-free transseptal puncture system, which directly competes with CIRCA's CrossWise RF Transseptal Access System. Both target electrophysiologists performing left atrial access for AF ablation and structural heart procedures, addressing similar procedural efficiency and safety pain points.
- CeloNova BioSciences: CeloNova BioSciences has commercialized the TEmpo esophageal temperature probe, which directly competes with CIRCA's S-CATH and MATRIX12 M products for AF ablation procedures. Both companies target electrophysiologists seeking rapid, accurate temperature monitoring to prevent esophageal thermal injury during ablation.
Broad incumbents
- Medtronic: Medtronic is a broad incumbent across cardiovascular and EP with ablation catheters, mapping systems, and cryoablation tools. While Medtronic is less directly competitive in esophageal temperature monitoring or transseptal access specifically, its broad EP portfolio and CryoCath acquisition position it as a bundled competitor for the same hospital customers CIRCA serves.
Emerging players
- Acutus Medical: Acutus Medical is an emerging player in EP diagnostics and access, with mapping systems and sheath products used in the same ablation procedures where CIRCA's tools are deployed. While Acutus focuses more on mapping and diagnostic catheters, both companies are smaller EP-focused players competing against the same large incumbents.
- Stereotaxis: Stereotaxis develops robotic EP navigation systems used in ablation procedures where CIRCA's temperature monitoring and access tools are deployed. While Stereotaxis focuses on remote magnetic navigation, both companies serve the same electrophysiology labs and face similar competitive dynamics against the major EP incumbents.
- CardioFocus: CardioFocus develops the HeartLight laser balloon ablation system for AF, an alternative ablation modality to the RF ablation workflows where CIRCA's esophageal temperature monitoring is most critical. As ablation technologies evolve, CardioFocus represents an emerging alternative workflow that could affect demand for traditional temperature monitoring tools.
