摘要:
The present technology relates to modular valve replacement systems for treating valve-related cardiac disorders. In select embodiments, the modular valve replacement system includes a fixation device and a permanent valve assembly. The fixation device and the permanent valve assembly are delivered separately, enabling use of smaller delivery systems and facilitating less-invasive implant techniques. The fixation device is implanted first and provides a mounting fixture for the subsequently delivered permanent valve assembly. In some embodiments, the permanent valve assembly is at least partially mechanically isolated from the fixation device after the permanent valve assembly is attached to the fixation device. In some embodiments, the fixation device includes a temporary valve assembly that prevents regurgitation until the permanent valve assembly is implanted.
