Intended Use

The PVR-100 / Vasogram is a noninvasive medical device used in conjunction with other devices such as: continuous-wave Doppler ultrasound, treadmill testing, and ultrasonic imaging techniques for vascular studies of the limbs and digits. Use of the PVR-100 / Vasogram in this manner allows the physician to noninvasively diagnosis extremity arterial and venous disorders, and receive, record, and produce a visual display of local arterial compliance.

Device Story

PVR-100/Vasogram II is a noninvasive diagnostic system for vascular studies. Device integrates with continuous-wave Doppler, treadmill testing, and ultrasonic imaging to assess limb and digit vasculature. System captures physiological signals to evaluate arterial and venous disorders; specifically, the Vasogram component measures, records, and displays local arterial compliance. Operated by physicians in clinical settings to aid in the diagnosis of extremity vascular conditions. Output provides visual data on arterial compliance, assisting clinicians in identifying arterial/venous pathology and informing treatment decisions.

Clinical Evidence

No clinical data provided; substantial equivalence based on technological characteristics and intended use comparison to the predicate device.

Technological Characteristics

Noninvasive vascular diagnostic system; integrates with Doppler ultrasound, treadmill, and ultrasonic imaging. Features include signal acquisition for arterial/venous assessment and local arterial compliance measurement. System provides visual display of compliance data. Connectivity and software details not specified.

Indications for Use

Indicated for patients requiring noninvasive vascular assessment of limbs and digits to diagnose arterial and venous disorders. Used by physicians in conjunction with Doppler ultrasound, treadmill testing, or ultrasonic imaging.
