Product Overview
The Medtronic Azure S DR MRI SureScan™ is an advanced cardiac device designed for patients requiring sophisticated pacing support. This system is indicated for rate-adaptive pacing and offers dual-chamber and atrial tracking modes, aiming to improve patient quality of life by synchronizing heart rhythms and preventing symptomatic bradycardia.
Key Features
- MRI SureScan™ Technology: Approved for 1.5T and 3T MRI use under specified conditions, allowing patients to undergo necessary MRI scans safely.
- BlueSync™ Ready: Facilitates wireless communication and data management.
- Extended Longevity: Offers over 10 years of projected service life.
- Updated MVP™ Algorithm: Enhances pacing performance and patient outcomes.
Physical Characteristics
The device features a compact design with specific physical dimensions and material composition optimized for patient comfort and biocompatibility. Key characteristics include a volume of 12.75 cm³, a mass of 22.5 g, and dimensions of 46.6 mm x 50.8 mm x 7.4 mm. Materials in contact with human tissue are titanium, polyurethane, and silicone rubber.
Pacing Parameters and Functionality
The Azure S DR MRI SureScan offers a comprehensive range of programmable pacing parameters, including various pacing modes (e.g., DDDR, AAIR), adjustable rates, pulse widths, and sensitivity settings for both atrial and ventricular pacing. It also includes advanced features like Atrial and Ventricular Capture Management, Rate Response, and Tachyarrhythmia detection and intervention.
Indications and Contraindications
This device is indicated for patients with symptomatic bradycardia, AV block, sinus node dysfunction, and other conditions benefiting from chronic cardiac pacing. It is contraindicated for concomitant implantation with other bradycardia devices or ICDs, and in patients who cannot tolerate pacing rates above the programmed Lower Rate. Specific contraindications also apply to dual-chamber sequential pacing and asynchronous pacing.
