Device Story

Temporary pacing leads (Models 6491, 6492, 6495, 6500) used for post-surgical cardiac pacing/sensing. Leads consist of electrodes, insulated multi-filament conductors, and fixation monofilaments; models include myocardial curved needles for tissue embedding and chest needles for exit through the chest wall. Bipolar model (6495) features bifurcated proximal connection. Operated by clinicians in surgical settings; leads connect to external pulse generators. Output is electrical pacing/sensing of myocardium. Leads are removed via gentle traction post-therapy. Benefits include temporary cardiac rhythm management following surgery. No part remains in body (except silicone disc in 6500).

Clinical Evidence

Bench testing only. No clinical data required or presented. Performance verified via biocompatibility, junction strength, and component qualification testing.

Technological Characteristics

Temporary pacing leads; unipolar and bipolar configurations. Materials include insulated multi-filament conductors, electrodes, and blue monofilament fixation sutures. Features myocardial curved needles and chest exit needles. Sterile, single-use. No software or electronic components; purely mechanical/electrical lead system.

Indications for Use

Indicated for temporary post-surgical atrial and/or ventricular pacing and sensing in patients requiring temporary cardiac support for 7 days or less. No specific age or gender restrictions; contraindications depend on patient-specific anatomy and medical condition.

#### Device Descriptions 6.1

## Model 6491 Unipolar Pediatric Temporary Pacing Lead

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 (see Figure 6-1) consists of an electrode (1) and an insulated multi-filament conductor (2) which are crimped together. A blue monofilament (3) proximally coiled for fixation of the lead is attached to the electrode and terminates distally in an atraumatic myocardial curved needle (4). A blue monofilament coil provides fixation while the lead is implanted in myocardial tissue. An atraumatic chest needle (5) 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.

Image /page/4/Figure/5 description: This image shows a diagram of a medical device with several labeled parts. The diagram includes labels for the electrode (1), insulated multi-filament conductor (2), blue monofilament coil (3), curved needle (4), and chest needle (5). The device appears to be a type of wire or catheter with a coiled section and needles at the ends.

## Model 6492 Unipolar Temporary Atrial Pacing Lead

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 (see Figure 6-2) consists of an electrode (1) and an insulated multi-filament conductor (2) which are crimped together. A blue monofilament (3) proximally coiled for fixation of the lead is attached to the electrode and terminates distally in an atraumatic myocardial curved needle (4). A blue monofilament coil provides fixation while the lead is implanted in myocardial tissue. An atraumatic chest needle (5) 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.

## Model 6495 Bipolar Temporary Myocardial Pacing Lead

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 (see Figure 6-3), which contains a distal, discrete, ring electrode (1), a discrete, tip electrode (2), and a coaxial conductor lead body (3). Each discrete electrode is crimped onto a conductor and terminates in an atraumatic myocardial curved needle (4). 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 (5) 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 (6), 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.

{7}------------------------------------------------

## Model 6500 Unipolar Temporary Myocardial Pacing Lead

The Medtronic Model 6500 Unipolar Temporary Myocardial 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 6500 Unipolar Temporary Myocardial Pacing Lead (see Figure 6-4) consists of an electrode (1) and an insulated multi-filament conductor (2) which are crimped together. A blue monofilament (3) proximally coiled for fixation of the lead is attached to the electrode and terminates distally in an atraumatic myocardial curved needle (4). A blue monofilament coil provides fixation while the lead is implanted in myocardial tissue. An atraumatic chest needle (5) 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 lead remains in the body, except the silicone rubber disc (6) in the case of atrial application.

and indicates the following similarities:

- Same intended use/indications ●
- Same operating principle
- Same fundamental technological characteristics ●
- Same overall design, dimensions, and performance
- All materials are the same except for the minor formulation change and new supplier of the blue monofilament suture.
- Same packaging materials ●
- Same sterilization requirements
