Profile: Acumen Medical, Inc. offers therapeutic device for heart. We provide Insight™ endocardial visualization system and Spirit™ navigable lead delivery catheter. The Spirit navigable lead delivery catheter is designed for navigation to a chosen pacing site in the coronary venous system, and the Spirit's hub integrates luers designed for both guide wire access and distal contrast or flush injections. Our Insight endocardial visualization system combines EP catheter steering and torque transmission with high-resolution, visible light imaging to enable positive confirmation of the coronary sinus ostium. The Variable Steering Radius™ provides a wide array of steering curves to enable coronary sinus access even in enlarged or atypical atria. It is reinforced with a stainless steel ribbon-wire braid designed for accurate torque transmission.
