St. Jude Offers Easier to Install ICD Connector System

St. Jude Medical's SJ4 connector system reduces the number of connections between the the ICD device to enable a streamlined implant procedure.

The SJ4 connector system features a single connection between the device and the defibrillation lead, and a single set screw (used to tighten and secure the lead to the device). Previous defibrillator lead designs required three separate connections and four set screws. The reduced number of lead connections also lessens the risk of lead-to-can abrasion, a known complication that can occur in patients who have an implantable device.

The St. Jude Medical SJ4 connector system is designed to meet the draft IS-4 standard as set forth by the International Organization of Standardization (ISO), but will not be labeled as such until the standard is finalized, which is expected later in 2009.

The Current Plus ICD was approved by the FDA in April 2009, along with the company’s Promote Plus cardiac resynchronization therapy defibrillator (CRT-D), which are compatible with the Durata SJ4 defibrillation lead. As with previously announced leads in the Durata lead family, the Durata lead with SJ4 connector features a soft silicone tip and Optim insulation, a hybrid insulation material that provides increased abrasion-resistance and durability, along with the flexibility and handling characteristics that facilitate device implantation.
