Guidant Corporation

• Advisor, Electrical Engineer

  • Jan 1999 - Apr 2006

  • Member of a team that added the first RF telemetry functionality to the company’s implantable defibrillators. Involved in the protocol development and did the digital IC design in Verilog and VHDL on a mixed language ASIC. Fully engaged through SCAN insertion, synthesis, timing analysis and verification. • Developed a protocol and automatic test system to measure sensitivity and specificity of Guidant’s implantable defibrillators. The test applied recorded electrograms containing various arrhythmias to the device inputs and recorded its responses. The results were submitted to the FDA in support of a new algorithm which classifies rhythms and determines when therapy is to be delivered. • Technical Lead of Test Group on Hardware Design Team. Responsible for design analysis and design verification testing of hardware for the company’s next generation automatic implantable defibrillator / pacemaker. Also, responsible for design and development of the system breadboard (PC board equivalent of the defibrillator hardware to be used in software development) production test development of the completed product and all laboratory equipment support for Redmond design team. Test generation includes: • Digital IC, ATPG SCAN and functional test vectors implemented on IMS Blazer test system. • Flex circuit, Boundary SCAN and functional testing using GPIB / VXI test system. • Completed product, functional tests using GPIB / VXI test system, software developed in LabVIEW. • Member of team that developed a new production test system for the company’s defibrillators.
