PRODUCT
1) ACUSON and SONOLINE Antares and Antares PE ultrasound systems at product versions 4.0 and 5.0 with cardiovascular options installed; ACUSON Antares 4.0 & 5.0: 10032747, 10037592, 10040728; ACUSON Antares PE 4.0 & 5.0: 10032746, 10037591, 10038202, 10040729; SONOLINE Antares 4.0 & 5.0: 05936518, 08653771, 10037593; Antares Cardio Options: 10036613, 10036588, 10036585, 10436250; The ACUSON Antare is a general purpose Diagnostic Ultrasound system. Its function is to acquire primary or secondary harmonic ultrasound echo data and display it in: B-Mode, M-Mode, Pulsed (PW) Doppler Mode, Continuous (CW) Doppler Mode, Color Doppler Mode, Amplitude Doppler Mode, a combination of modes, Harmonic Imaging, or 3D/4D imaging on a FPD display. The Antares ultrasound imaging system is intended for the following applications: Abdominal, Intraoperative, Small Parts, Transcranial, OB/GYN, Cardiac, Transesophageal, Pelvic, Neonatal/Adult Cephalic, Vascular, Intravascular, Musculoskeletal, Superficial Musculoskeletal, Great Vessel, and Peripheral Vascular applications. The system also provides for the measurement of anatomical structures that provide information that is used for clinical diagnosis purposes. Recall # Z-1836-2011;
2) ACUSON S2000 ultrasound systems (all versions) with cardiovascular options installed; ACUSON S2000: 10041461; S2000 Cardio Option: 10041853; The ACUSON S2000 Ultrasound System is a multi-purpose mobile, software controlled diagnostic ultrasound system with and on-screen display for thermal and mechanical indices related to potential bio-effect mechanisms. Its function is to acquire primary or secondary harmonic ultrasound echo data and display it in B-Mode, M-Mode, Pulsed (PW) Doppler Mode, Continuous (CW) Doppler Mode, Color Doppler Mode, Amplitude Doppler Mode, a combination of modes, or Harmonic Imaging and 3D/4D Imaging on a Flat Panel Display. The ACUSON S2000 ultrasound imaging systems are intended for the following applications: Fetal, Abdominal, Intraoperative, Pediatric, Small Parts, Transcranial, OB/GYN, Cardiac, Pelvic, Neonatal/Adult Cephalic, Vascular, Musculoskeletal, Superficial Musculoskeletal, and Peripheral Vascular applications. The system also provides the ability to measure anatomical structures {fetal, abdominal, intraoperative, intraoperative neurological, pediatric, small organ, neonatal cephalic, adult cephalic, cardiac, trans-esophageal, transrectal, transvaginal, peripheral vessel, musculoskeletal (conventional), musculo-skeletal (superficial) and neonatal cardiac} and calculation packages that provide information that provide information to the clinician that may be used adjunctively with other medical data obtained by a physician for clinical diagnosis purposes. Recall # Z-1837-2011;
3) ACUSON X300, X300 PE and SONOVISTA X300 (all versions) with cardiovascular options installed; ACUSON X300: 10037409, 10132987, 10038837; SONOVISTA X300: 10133170; ACUSON X300 PE: 10348531, 10348532, 10348533; X300 Cardiovascular Options: 10133037, 10348777, 10349032, 10427797, 10427822 10427816, 10563788; The Siemens Acuson X300 ultrasound imaging system is intended for the following applications: General Radiology, Fetal, Abdominal, Intraoperative, Pediatric, Small Parts, Neonatal/Adult Cephalic, Cardiac, Transesophageal, Pelvic, Transcranial, OB/GYN, Urology, Vascular, Musculoskeletal, Superficial Musculoskeletal, and Peripheral Vascular applications. The system also provides for the measurement of anatomical structures and for analysis packages that provide information that is used for clinical diagnosis purposes. Recall # Z-1838-2011
REASON:
There is an error in the estimation of mean pressure gradient in the Cardiac measurement package. The currently implemented calculation will result in an underestimation of the mean pressure gradient (PGmean) when estimated from a trace of the Doppler waveform of the stenotic flow..
