Important Safety Information

Caution: In the United States, the Corvia® Atrial Shunt System is an investigational device, limited by United States law to investigational use.

MAGNETIC RESONANCE (MR) IMAGING INFORMATION

MR Triangle alert

Non-clinical testing demonstrated that the Corvia Atrial Shunt is MR Conditional. A patient with this device can be scanned safely in an MR system immediately after placement under the following conditions:

  • Static magnetic field of 1.5-Tesla and 3-Tesla, only
  • Maximum spatial gradient magnetic field of 4,000-Gauss/cm (40-T/m) or less
  • Maximum MR system reported, whole body averaged specific absorption rate (SAR) of <2 W/kg (Normal Operating Mode)

Under the scan conditions defined, the Corvia Atrial Shunt is expected to produce a maximum temperature rise of 2.4°C after 15-minutes of continuous scanning (i.e., per pulse sequence).

In non-clinical testing, the image artifact caused by the Corvia Atrial Shunt extends approximately 5mm from this device when imaged using a gradient echo pulse sequence and a 3-Tesla MR system. The device shunt lumen cannot be visualized on T1-weighted, spin echo and gradient echo pulse sequences.
