Brief Summary: Prior to using these devices, please review the User’s Manual for a complete listing of indications, contraindications, warnings, precautions, potential adverse events and directions for use.

Indications: The IsoFlex® S lead is designed for use in combination with a compatible pulse generator to provide permanent pacing and sensing in either the atrium (Models 1643K and 1642T are j-shaped) or ventricle (Models 1645K or 1646T).

Contraindications: The use of IsoFlex® S leads is contraindicated in patients who are expected to be hypersensitive to a single dose of 1.0 milligram of dexamethasone sodium phosphate.

The use of Models 1645K and 1646T is also contraindicated in the presence of tricuspid atresia and in patients with mechanical tricuspid valves.

Potential Adverse Events: The IsoFlex® S pacing lead clinical trial involved 65 Model 1642T and 93 Model 1646T leads implanted in 95 patients. Cumulative implant duration by lead location is as follows: atrium: 7704 days (mean implant duration 120.4 days, range 1 to 210 days), ventricle: 12144 days (mean implant duration 129.2 days, range 35 to 219 days).
