Intended Use
The Blazer Dx-20 is a diagnostic catheter indicated for temporary use in electrophysiology studies for intracardiac stimulation (pacing) and/or recording of electrical potentials.
Device Description
The Boston Scientific Corporation Blazer Dx-20 is a sterile, single use steerable diagnostic electrophysiology catheter used to record intracardiac electrical potentials. The Blazer Dx-20 Catheter is also used to deliver pacing stimuli from an external source. The Blazer Dx-20 Catheter is a bi-directionally steerable diagnostic catheter built on a modified SteeroCath Dx shaft platform with a molded handle. It has one tip electrode and up to 19 ring electrodes for a total of 20. The ring spacing configurations vary with each model. The catheter shaft of the Blazer Dx-20 is equivalent to the SteeroCath Dx Catheter, which is designed to allow for a standard curve of the catheter distal section. The catheter shaft has a soft distal section in order to minimize trauma and risk of perforation. The Blazer Dx-20 Catheters use a thumb-actuated bidirectional steering mechanism. contained within an ergonomically shaped cylindrical handle that is also utilized by the currently marketed SteeroCath Dx Diagnostic catheters. A thumb-level motion of the piston actuates the steering of the distal tip. The catheter is placed into the heart and is guided to location by steering the distal tip area of the catheter. Tip and ring electrodes come into contact with the endocardium where electrical contact is made and pacing and recording of electrograms becomes possible. No new technology or circuitry is associated with the transmission of electrical signals to or from the endocardium - the Blazer Dx-20 Catheter relies on platinum-iridium alloy, ring electrodes whose circuitry is identical to standard electrode and pacing catheters. Additionally, the electrical connections made (catheter to EP recorder) are similar to those for commercially available electrode recording and pacing v catheters.
More Information

No
The device description focuses on the mechanical and electrical components of a standard diagnostic catheter and explicitly states "No new technology or circuitry is associated with the transmission of electrical signals". There is no mention of AI or ML in the provided text.

No

The device is described as a "diagnostic catheter" used for "recording of electrical potentials" and "delivering pacing stimuli from an external source" for "electrophysiology studies," which points to diagnostic and temporary pacing functions rather than long-term therapeutic treatment.

Yes
The "Intended Use / Indications for Use" section explicitly states, "The Blazer Dx-20 is a diagnostic catheter indicated for temporary use in electrophysiology studies for intracardiac stimulation (pacing) and/or recording of electrical potentials." The "Device Description" also mentions it is a "diagnostic electrophysiology catheter used to record intracardiac electrical potentials." Both statements confirm its diagnostic purpose.

No

The device description clearly details a physical catheter with electrodes, a steerable shaft, and a handle, indicating it is a hardware medical device, not software-only.

No, the Blazer Dx-20 is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro (outside the body) for the examination of specimens derived from the human body to provide information for diagnostic purposes. This includes things like blood tests, urine tests, and tissue biopsies analyzed in a lab.
  • Blazer Dx-20 Function: The description clearly states the Blazer Dx-20 is a diagnostic catheter used for intracardiac stimulation (pacing) and/or recording of electrical potentials within the heart. This is an in vivo (within the body) procedure.
  • Mechanism of Action: The device works by making electrical contact with the endocardium to record and deliver electrical signals directly within the heart. It does not analyze specimens outside the body.

Therefore, based on the provided information, the Blazer Dx-20 is an in vivo diagnostic device, not an in vitro diagnostic device.

Dear Ms. Malmborg:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act
