No
The device description focuses on the physical components and mechanical aspects of temporary pacing leads. There is no mention of software, algorithms, or data processing that would suggest the use of AI or ML. The performance studies are limited to bench testing of material properties.
Yes
Explanation: The device is intended for "temporary postsurgical atrial and ventricular pacing and sensing," which directly addresses and treats a physiological condition (cardiac rhythm), making it a therapeutic device.
No
The device is described as a "Temporary Pacing Lead/Wire" intended for "temporary postsurgical atrial and ventricular pacing and sensing." Its primary function is pacing, which is a therapeutic intervention, not a diagnostic one. While it mentions "sensing," this is typically for the purpose of guiding pacing, not for independent diagnostic interpretation.
No
The device description clearly details physical components such as lead bodies, electrodes, conductors, needles, and connector pins, indicating it is a hardware device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
- Device Function: The described devices are temporary pacing leads and wires. Their function is to provide electrical stimulation to the heart muscle (myocardium) for temporary pacing and sensing. This is a direct intervention on the body, not a test performed on a sample taken from the body.
- Intended Use: The intended use is for temporary postsurgical atrial and ventricular pacing and sensing. This is a therapeutic and monitoring function, not a diagnostic test performed on a sample.
- Device Description: The device description details the physical components of the leads and wires, designed for implantation into the heart muscle. This aligns with an implantable or interventional device, not an IVD.
Therefore, the Model 6491, 6492, 6494, and 6495 temporary pacing leads and wires are not IVD devices. They are considered medical devices used for temporary cardiac pacing.

Device Description
The Medtronic Model 6491 Unipolar Pediatric Temporary Pacing Lead is designed for use in both the atrium and the ventricle. The unipolar lead is comprised of a lead body with the distal and proximal segment. The Model 6491 Unipolar Pediatric Temporary Pacing Lead consists of an electrode and an insulated multi-filament conductor which are crimped together. A blue monofilament proximally coiled for fixation of the lead is attached to the electrode and terminates distally in an atraumatic myocardial curved needle. A blue monofilament coil provides fixation while the lead is implanted in myocardial tissue. A curved atraumatic chest needle at the proximal end of the conductor wire permits exiting the pacing lead through the chest wall. To remove the pacing lead, gentle traction should be applied. No part of the Medtronic Model 6491 Unipolar Pediatric Temporary Pacing Lead remains in the body.
The Medtronic Model 6492 Unipolar Temporary Atrial Pacing Lead is designed for use in the atrium. The unipolar lead is comprised of a lead body with distal and proximal segments. The Model 6492 Unipolar Temporary Atrial Pacing Lead consists of an electrode and an insulated multi-filament conductor which are crimped together. A blue monofilament proximally coiled for fixation of the lead is attached to the electrode and terminates distally in an atraumatic myocardial curved needle. A blue monofilament coil provides fixation while the lead is implanted in myocardial tissue. An atraumatic chest needle at the proximal end of the conductor wire permits exiting the pacing lead through the chest wall. To remove the pacing lead, gentle traction should be applied. No part of the Medtronic Model 6492 Unipolar Temporary Atrial Pacing Lead remains in the body.
The Medtronic Model 6494 Unipolar Temporary Myocardial Pacing Wire is designed for use in both the atrium and the ventricle. The two leads are comprised of a lead body with distal and proximal segment. The Model 6494 Unipolar Temporary Myocardial Pacing Wire consists of two insulated multi-filament wire. At one end of each wire has been stripped to have an electrode surface. This surface area can partly or completely be used as an electrode. The stripped end terminates distally in an atraumatic myocardial curved needle. An atraumatic chest needle at the proximal end of the conductor wire permits running the pacing wire to exit through the chest wall. To remove the pacing wire, gentle traction should be applied. No part of the Medtronic Model 6494 Unipolar Temporary Myocardial Pacing Wire remains in the body.
The Medtronic Model 6495 Bipolar Temporary Myocardial Pacing Lead is designed for use in both the atrium and the ventricle. The bipolar lead is comprised of a lead body with distal and proximal segments which includes the integrated bifurcated proximal lead connection. The Model 6495 Bipolar Temporary Myocardial Pacing Lead consists of an insulated multifilament lead, which contains a distal, discrete, ring electrode, a discrete, tip electrode, and a coaxial conductor lead body. Each discrete electrode is crimped onto a conductor and terminates in an atraumatic myocardial curved needle. The curved needle is used to create a channel in the myocardium for embedding the electrodes. A blue monofilament coil provides fixation while the lead is implanted in myocardial tissue. An atraumatic chest needle at the proximal end of the conductor wire permits exiting the pacing lead through the chest wall. Terminated on the back of the chest needle are two breakaway connector pins, which provide an attachment to an external pulse generator. No part of the Medtronic Model 6495 Bipolar Temporary Myocardial Pacing Lead remains in the body.

6.4 Comparison of the Predicate Device
A comparison of the Streamline family of products is being made to the currently marketed predicate devices:
Models 6491, 6492, 6495 510(k) # K171253 and 6494 510(k) #K140972 and indicate the following similarities:
- Same intended use/indications ●
- Same operating principle ●
- Same fundamental technological characteristics ●
- Same overall design, dimensions, and performance ●
- o All materials are the same except for the minor formulation change of the base polyethylene (PE) material used for the insulation coating of the wire; The insulated wire comes in three different colors (yellow, purple, and blue) and no changes are being made to the supplier, chemical compositions or to the concentrations of these colorants.
- Same packaging materials ●
- Same sterilization requirements
