Intended Use

Arox bipolar, passive-fixation, endocardial pacing leads (Arox xx-JBP) are intended to provide permanent pacing and sensing in the atrium and or ventricle when used with a compatible pulse generator.

Device Story

Arox leads are bipolar, passive-fixation, endocardial pacing leads; available in straight or J-shaped configurations for atrial or ventricular placement. Device features four silicone tines for passive fixation in heart trabeculae. Tip electrode uses platinum/iridium base with fractal iridium surface (3.5 mm²); ring electrode uses platinum/iridium base with fractal iridium surface (22.6 mm²). Lead conductor consists of quadrifilar MP35N wire in coaxial configuration; insulated with silicone rubber tubing; utilizes 3.2 mm IS-1 connector. Used by physicians in clinical settings to provide permanent pacing/sensing when connected to a compatible pulse generator. Modifications from predicate Merox leads include increased tip electrode surface area and lenticular tip shape, matching the Polyrox lead family.

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

# Arox Passive-Fixation, Bipolar, Endocardial Pacing Lead Special 510(k) Premarket Notification

# 1. 510(K) SUMMARY

Name and Address of Sponsor:

6024 Jean Road Lake Oswego, OR 97035 Establishment Registration Number: 1028232 Device Name: Proprietary Name: Arox Leads Classification: Class III (21 CFR 870.3680(b)) Classification Name: Cardiovascular Permanent Pacemaker Electrode Product Code: DTB Date Prepared: April 16, 2002

### General Description:

The BIOTRONIK Arox lead is a bipolar, passive-fixation, endocardial pacing lead available in straight and " J"-shaped configurations, for placement in the ventricle or atrium. The designation Arox xx-BP refers to Arox straight leads, which are available in lengths (xx) of 53 or 60 cm; Arox xx-JBP refers to Arox "J"-shaped leads, which are available in lengths of 45 and 53 cm.

The Arox xx-JBP model has a permanent bend proximal to both lead electrodes, resulting in the distal portion of the lead body having what is commonly referred to as a "U" or "J" shape. This lead shape facilitates placement in the right atrial appendage.

Arox xx-BP and Arox xx-JBP leads feature four silicone tines for passive-fixation in the heat's trabeculae. The tip electrode is made of a platinum/iridium base material, with a fractal iridium surface and electrically active surface area of 3.5 mm². The ring electrode is made of a platinum/iridium base material, with a fractal iridium surface and electrically active surface area of 22.6 mm². The lead conductor consists of quadrifilar MP35N wire in a coaxial configuration, insulated with silicone rubber tubing. All Arox leads utilize a 3.2 mm IS-1 connector.

#### Device Modification:

The Arox leads introduced in this Special 510(k) notification are modified versions of BIOTRONIK's currently marketed Merox leads (#K010281, dated 04-09-02). The modifications are a change in the tip electrode surface area from 1.3 mm² to 3.5 mm² and a change in the shape of the tip from segmented to lenticular. The tip electrode surface area size and shape are identical to BIOTRONIK's currently marketed Polyrox family of passive-fixation, endocardial leads (#K000763, dated 04-06-00).

### Predicate Devices:

BIOTRONIK proposes the following leads cleared through 510(k) notifications as predicate devices for the Arox leads:

- BIOTRONIK's Merox passive-fixation, endocardial leads (#K010281, dated 04-09-02)
- BIOTRONIK's Polyrox passive-fixation, endocardial leads (#K000763, dated 04-06-00) ●

#### Indication for Use:

Arox bipolar, passive-fixation, endocardial pacing leads (Arox xx-BP and Arox xx-JBP) are intended to provide permanent pacing and sensing in the atrium and or ventricle when used with a compatible pulse generator.

Dear Mr. Brumbaugh:

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.
