• What is the primary purpose of the Model 255A Programmer III and how does it differ from other pacemaker programmers?

  The Model 255A Programmer III is designed specifically to control and adjust the operating parameters—such as pacing rate, output, and timing—of implanted cardiac pacemakers. Unlike some other programmers, it is tailored for precise programming of pacing functions in clinical settings like electrophysiology labs or hospital ECG departments, ensuring optimized patient therapy. Its software revision (Rev. 4004) suggests it may include updated features or improvements over earlier models, though the exact differences would require consulting the manufacturer’s documentation.

• Is the Model 255A Programmer III a single-use or reusable device, and what maintenance is required?

  The Model 255A Programmer III is a reusable electronic unit, meaning it is not intended for single-use disposal. While it does not require sterility (as it is not used in direct patient contact), it must be maintained according to the manufacturer’s guidelines to ensure accurate and reliable operation. Proper calibration, software updates, and routine servicing are critical to its performance.

• What regulatory pathway does the Model 255A Programmer III follow, and what does this mean for its use?

  The Model 255A Programmer III follows the FDA’s 510(k) clearance pathway, classified as a Class III device under regulation number 870.3700. This classification indicates it is subject to stringent oversight due to its role in controlling life-sustaining cardiac devices. The device holds a traditional 510(k) clearance (K882429) and was reviewed by the FDA’s Cardiovascular (CV) Advisory Committee, ensuring it meets safety and effectiveness standards for use in clinical settings by trained healthcare professionals.

• Who is authorized to use the Model 255A Programmer III, and where is it typically deployed?

  The Model 255A Programmer III is intended for use by trained healthcare professionals, specifically in specialized environments like cardiac electrophysiology labs or hospital electrocardiography departments. Its design and programming capabilities are tailored for clinical applications where precise adjustments to implanted pacemakers are required, ensuring optimal patient therapy under medical supervision.
