4.4. LEAD EVALUATION AND LEAD CONNECTION
PARADYM RF VR 9250 has two DF-1 and one IS-1 connector ports.
IS-1 refers to the international standard whereby leads and
generators from different manufacturers are assured a basic fit (ISO
5841-1:2000). DF-1 refers to the international standard for
defibrillation lead connectors (ISO 11318:2002).
Do not tie a ligature directly to the lead body, tie it too tightly, or
otherwise create excessive strain at the insertion site as this may
damage the lead. Use the lead stabilizer to secure the lead lateral to
the venous entry site.
Do not immerse the lead in mineral oil, silicone oil, or any other
liquid.
Do not grip the lead with surgical instruments.
Do not use excessive force or surgical instruments to insert a stylet
into a lead.
Use ventricular transvenous leads with caution in patients with either
a mechanical or bioprosthetic tricuspid valvular prosthesis.
Use the correct suture sleeve (when needed) , to immobilize the lead
and protect it against damage from ligatures.
Never implant the system with a lead system that has a measured
shock impedance of less than 30 ohms. A protection circuit in the
defibrillator prevents shock delivery when impedance is too low. If the
shock impedance is less than 30 ohms, reposition the lead system to
allow a greater distance between the electrodes.
Do not kink leads. Kinking leads may cause additional stress on the
leads, possibly resulting in lead fracture.
Do not insert a lead connector pin into the connector block without
first visually verifying that the setscrews are sufficiently retracted. Do
not tighten the setscrews unless a lead connector pin is inserted
because it could damage the connector block.
