May 2019Undisclosed stageKennedy Lewis Investment Management (lead)$55MCardioFocus, Inc. is a medical device company headquartered in Marlborough, Massachusetts, focused on advancing ablation treatments for cardiac disorders, particularly atrial fibrillation (AFib), the most common heart arrhythmia. The company develops and manufactures the FDA-approved HeartLight Endoscopic Ablation System, a catheter-based technology featuring direct visualization and titratable laser energy, which has treated over 6,500 patients in the US, Europe, and Japan. In March 2019, it received European CE Mark approval for the next-generation HeartLight X3 System. On May 28, 2019, CardioFocus completed a $55 million financing round with participation from its existing syndicate of institutional investors, including senior debt from Kennedy Lewis Investment Management. The proceeds were designated to accelerate the commercial introduction of the HeartLight Endoscopic Ablation System and support the global launch of the HeartLight X3 System. Kennedy Lewis, an opportunistic credit manager specializing in long-term, flexible growth financing for commercial-stage healthcare companies, led this effort through its Life Sciences group. Paul A. LaViolette, Executive Chairman, highlighted the investment's role in enabling broader adoption of the HeartLight System and a successful commercial launch of HeartLight X3 to advance AFib treatment. The deal ranked as a notable private equity transaction in the medical devices sector for Q2 2019. CardioFocus has raised over $312 million across 25 rounds historically, with later activity including a Series G - II round of $27.15 million in February 2023 and an acquisition of Galvanize - Electrophysiology Technology Business in January 2024. The company continues innovating in pulsed field ablation and electrophysiology technologies.
Mar 2017Undisclosed stage-$20MCardioFocus, a Marlborough, Massachusetts-based medical device company, develops laser-based ablation systems for treating cardiac arrhythmias, particularly atrial fibrillation (AF). Its flagship product, the HeartLight Endoscopic Ablation System, received CE Mark in 2009, U.S. FDA approval in April 2016, and Japanese approval in July 2017, enabling commercialization in Europe, the U.S., and Japan. The system uses direct visualization and titratable laser energy for pulmonary vein isolation procedures, with over 5,000 patients treated by mid-2018. In March 2017, CardioFocus completed a $20 million equity financing round with participation from its existing syndicate of institutional investors, including SV Health Investors. The proceeds supported expanding commercialization of the HeartLight system in the U.S. following FDA approval and advanced technology development, including the next-generation Excalibur Balloon, anticipated for European regulatory approval by year-end 2017. The atrial fibrillation catheter ablation market exceeded $1.5 billion globally, growing at 15% annually, projected to reach $2 billion in 2017. Subsequent financings included a $55 million round in May 2019 (partly debt from Kennedy Lewis Investment Management) for global launch of the HeartLight X3 system, $13 million debt from Trump Securities in April 2018, $21 million senior secured convertible note from GPB Capital in June 2018 (with $13 million initial tranche tied to revenue targets), and an $8 million equity sale in May 2019. Japan Lifeline expanded its distribution partnership in 2017, investing to accelerate global HeartLight expansion and HeartLight X3 development, targeting full Japanese commercial launch in 2018 post-reimbursement.
Jan 2015Undisclosed stage-$32MCardioFocus is a medical device company based in Marlborough, Massachusetts, specializing in laser-based ablation systems for treating atrial fibrillation (AFib), including the HeartLight Endoscopic Ablation System and later HeartLight X3. CardioFocus focused on advancing AFib treatments amid a market opportunity noted as $2 billion in 2006, emphasizing minimally invasive endoscopic laser ablation over traditional methods. Earlier, in April 2006, it completed a $21.5 million Series C financing led by H.I.G. Ventures and KBL Healthcare Ventures to support a U.S. pivotal trial for its endoscopically-guided catheter ablation system. Subsequent rounds included $30.6 million for European launch and U.S. trials, $31.7 million equity offering around 2017 with a Japan distribution deal via Japan Lifeline, $55 million in 2019 for HeartLight X3 commercialization, and others up to Series G in 2023, totaling over $312 million across 25 rounds. Sources mention clinical progress like treating over 6,500 patients with HeartLight by 2019, positive trial results for HeartLight X3 showing rapid pulmonary vein isolation, and partnerships like expanded collaboration with Japan Lifeline for Asia Pacific commercialization. The company received CE Mark for HeartLight X3 in 2019 but awaited U.S. FDA approval at that time. The firm was partially acquired in 2024 as part of its electrophysiology technology business.
