Intended Use

INTERIM™ AV Temporary Pacing Catheters are indicated for temporary use in ventricular intracardiac pacing and intracardiac sensing in either the atrial or ventricular chambers.

Device Story

Temporary pacing catheter (Model INT-AV610) used for intracardiac pacing and sensing. Device features radiopaque PEBAX tubing with braided wire core; includes two atrial ring electrodes, one ventricular ring electrode, and one terminal contact tip electrode (all platinum-iridium). Proximal end has 2 mm gold-plated pin connectors for external pacemaker attachment. Design incorporates a Cournand curve at the ventricular tip and a secondary 90-degree offset atrial lobe (20 mm amplitude, 75 mm wide) to facilitate atrial wall contact for sensing. No internal stiffening wires used; shape maintained by PEBAX insulation. Used by clinicians in clinical settings to provide temporary cardiac pacing/sensing. Output is electrical signal transmission between heart and external pacemaker. Benefits include improved atrial sensing via anatomical conformance.

Clinical Evidence

No clinical studies performed on the subject device. Feasibility studies were conducted using a catheter with a similar electrode configuration to determine optimal atrial electrode location for sensing potential.

Technological Characteristics

6F diameter catheter. Materials: PEBAX (polyether block amide) thermoplastic insulation, platinum-iridium electrodes, braided stainless steel conductive wire, gold-plated pin connectors. Patient-contacting materials: PEBAX and platinum-iridium. Features Cournand curve and 90-degree offset atrial lobe. No internal stiffening wires. Passive device; no software or energy source.

Indications for Use

Indicated for patients requiring temporary ventricular intracardiac pacing and intracardiac sensing in either the atrial or ventricular chambers.

Regulatory Classification

Identification

Temporary pacemaker electrode: A device consisting of flexible insulated electrical conductors with one end connected to an external pacemaker pulse generator and the other end applied to the heart. The device is used to transmit a pacing electrical stimulus from the pulse generator to the heart and/or to transmit the electrical signal of the heart to the pulse generator. Permanent pacemaker electrode: A device consisting of flexible insulated electrical conductors with one end connected to an implantable pacemaker pulse generator and the other end applied to the heart. The device is used to transmit a pacing electrical stimulus from the pulse generator to the heart and/or to transmit the electrical signal of the heart to the pulse generator.

Predicate Devices

## Indication for Use and Description of Subject Device:

The subject device is indicated for temporary use in ventricular intracardiac pacing and intracardiac sensing in either the atrial or ventricular chamber. The catheter consists of radiopaque polymer (PEBAX) tubing encapsulating a braided wire core for optimum torque response. All electrodes, the two atrial ring electrodes and one ventricular ring electrode and a terminal contact tip electrode, are platinum-indium for maximum conductivity. The electrodes terminate at the proximal end of the catheter with 2 mm goldplated pin connectors for connection with the temporary external pacemaker. The INTERIMIM AV Shaped Temporary Pacing Catheter has a Cournand curve at the ventricular tip and a second curve (offset from the Cournand curve by 90°) in the region from 112 mm to 187 mm from the distal tip electrode. This curve or atrial lobe is 20 mm in amplitude and 75 mm wide. The atrial lobe is centered around the atrial ring-electrode pair to conform with the shape of the atrium endocardium. The atrial lobe and the Cournand curve are permanently set by the same manufacturing process which relies only on the PEBAX insulation to maintain the curved shape. No internal stiffening wires are used. The curve is intended to permit positioning of the atrial electrodes in contact or close proximity to the atrial wall for atrial sensing. The Model INT-AV610 is a 6F diameter catheter.

The materials use in the INTERIM™ AV Shaped Temporary Pacing Catheter are: PEBAX® (polyether block amide) thermoplastic insulation, platinum-iridium electrodes, braided stainless steel conductive wire and gold plated pin connectors. Only the PEBAX® insulation and the platinum-iridium electrodes are patient contacting.

Feasibility studies were conducted using a catheter with a similar electrode configuration to that of the subject device. These studies were used to determine the optimal location for the atrial electrodes with regard to atrial sensing potential. Clinical studies using the actual design of the subject device were not performed.
