DEVICE FEATURES
Detailed Device Description
Features of the EASYTRAK™ 2 IS-1 lead include the following:
•
Over-The-Wire Lead Design:
The lead design consists of an open-
lumen conductor coil that tracks over a 0.014-in (0.36-mm) diameter
guide wire.
•
Steroid:
The silicone rubber collar between the lead tip and distal
electrode contains a nominal dose of 0.7 mg dexamethasone acetate.
Upon exposure to body fluids, the steroid elutes from the lead to help
reduce tissue inflammation response at the distal electrode.
•
Slotted-Ring Dual
-
Electrodes with IROX Coating:
The two slotted-
ring electrodes provide a pacing and sensing surface in the coronary
venous system. The IROX™ coating creates a larger surface area for
sensing while maintaining a smaller electrode diameter for pacing, which
reduces polarization potentials.
•
Pace/Sense Configurations:
The EASYTRAK 2 IS-1 lead offers
various pace/sense configurations depending upon the programming
options of a compatible Boston Scientific CRT heart failure device. Refer
to the pulse generator manual for instructions.
•
Distal Tip:
The distal tip is protected by molded silicone rubber. This
protection allows for lead advancement through the coronary venous
system.
•
Tined Fixation:
Two silicone tines provide passive fixation of the lead
after surgical placement.
•
Lead Body:
The distal portion of the lead body is 5.4F in diameter and
consists of a coradial (corrosion-resistant, multifilar) coil that provides
two conductive pathways. The conductor filars are individually sheathed
in Ethylene Tetrafluoroethylene (ETFE) insulation and the conductor coil
is sheathed in silicone insulation. In addition, the silicone rubber is
covered with a polyurethane protective sleeve.
•
IS-1 Bipolar Connector:
The industry standard connector can be used
in conjunction with a compatible cardiac resynchronization therapy
(CRT) device with IS-1 ports.
