Titanium Grade 36 to Titanium Grade 1 weld on Implantable Cardioverter Defibrillator (ICD)
Zusammenfassung
Finding cost reduction on medical
devices production, a new Feedthrough array design
will be implemented in an Implantable Cardioverter
Defibrillator, incorporating glassed Feedthrough of
Titanium Grade 36 in a ferrule with glass insulator.
This design will be used in place of the brazed
Feedthrough of Niobium Type 2 in a ferrule with
sapphire as insulator utilized in legacy devices. The
Titanium Grade 36 Feedthrough will be welded per
Resistance Spot Welding to Interconnect Ribbons of
Titanium Grade 1. Being the first time that will be
used of Titanium Grade 36 as material on
Feedthrough, this new weld will be analyzed and
characterized to meet the device requirement and
obtain the economic impact of the material change
with a benefit of $18-20M NPV. The Design for
Reliable Manufacturing method demonstrate that a
robust characterization design can be development
in order to meet the specification as implement the
new FT array knowing all effected factors.
