We are currently marketing three products:

CVProfilor® DO-2020 CardioVascular Profiling System. The CVProfilor® DO-2020 System has been approved by the FDA, and is being marketed to primary care physicians and other health care professionals within the United States. These physicians and other health care professionals can either purchase the CVProfilor® DO-2020 directly from us, lease it through a third-party capital lease, or rent it from us on a "per-patient-tested" rental basis.

Utilizing our Central Data Management Facility, or CDMF, we are able to track utilization of the CVProfilor® DO-2020 System in each physician's office and medical clinic and to invoice our physician customers based on the number of CardioVascular Profile Reports (CVProfile Reports) which they generate each month.

HDI/PulseWaveCR-2000 Research CardioVascular Profiling System. The CR-2000 Research System is being marketed worldwide "for research purposes only" to clinical research investigators for the purpose of collecting data in cardiovascular studies. Further, because the CR-2000 Research System bears the CE Mark (CE 0123) and meets the European Union Medical Device Directive, physicians may use the CR-2000 Research System with patients in a clinical setting in the European Union.

CVProfilor® MD-3000 CardioVascular Profiling System. The CVProfilor® MD-3000 System is the international version of the CVProfilor® DO-2020 System designed for physicians outside the United States. The CVProfilor® MD-3000 System has a CE Mark (CE 0123) that allows it to be marketed within European Union countries.
