Acutus Medical's acquisition of Rhythm Xience brings the Flextra steerable introducer sheath into Acutus Medical's product portfolio.
May 17, 2019 — At the 40th annual Heart Rhythm Scientific Sessions, May 8-11 in San Francisco, Acutus Medical announced the agreement to acquire Rhythm Xience Inc., and new strategic partnerships with Peerbridge Health, Cardiac Designs and MedFact. Acutus' expanded portfolio builds on the organization's mapping and visualization technology platform.
The Rhythm Xience acquisition and partnership agreements create a foundation for Acutus to provide solutions spanning access, therapy, diagnostics and rhythm monitoring:
Access Sheaths and Introducers
Acutus is acquiring Rhythm Xience, known for its integrated family of novel and user-friendly transseptal crossing and steerable introducer systems. This acquisition expands Acutus' ability to improve access and effectively treat arrhythmias with: Flextra, a two-way steerable introducer sheath; Guider, a fixed curve introducer; and Lancer, a transseptal crossing device. All products are U.S. Food and Drug Administration (FDA)-cleared and commercially available.
Monitoring
To ensure early detection as well as to validate treatment efficacy, Acutus has partnered with Peerbridge Health to offer the advanced ambulatory Peerbridge Cor electrocardiogram (ECG). The Peerbridge system offers a truly wireless multi-channel ECG monitor that is FDA-cleared to detect up to 26 different arrhythmias. The system records every heartbeat for up to seven days and can transmit patient-activated events via the cloud, ensuring accelerated arrhythmia detection by clinical staff. At the end of each test, a quantitative analysis and atrial fibrillation (AFib) burden summary is delivered to prescribing physicians summarizing every cardiac event, both asymptomatic and patient-activated.
For longer-term remote monitoring, the Acutus QCheck handheld ECG and mobile app are now available through a partnership with Cardiac Designs. When individuals experience arrhythmia symptoms, QCheck records heart data and quickly displays results in the mobile app, which can then be transmitted to a medical professional via email or text. QCheck is available in the Apple App Store and Google Play by prescription or over the counter. All monitoring products are FDA-cleared and commercially available.
Robotic Ablation Catheters to Deliver Therapy Solutions
Acutus has signed an exclusive agreement with MedFact to distribute its robotically enabled point radiofrequency (RF) ablation catheter utilized for the Stereotaxis robotic navigation system. This agreement further enhances Acutus' integration with the Stereotaxis navigation system announced earlier this year.
The Acutus portfolio also includes its AcQMap advanced cardiac imaging and mapping system. AcQMap incorporates precision ultrasound atrial anatomy reconstruction and highly reproducible, high-definition non-contact charge density mapping. The system also provides workhorse contact mapping capabilities, now available in Europe. AcQMap's increased clarity of arrhythmia pattern mapping aids in the development of patient-specific ablation strategies. Unique to this system, physicians can rapidly remap and confirm the efficacy of each ablation.
