Is nesiritide available in the US?

I understand that nesiritide is a medication used to treat certain heart conditions, such as acute decompensated heart failure. My question is, is nesiritide currently available for use in the United States? I am aware that availability of medications can vary based on factors such as safety, efficacy, and FDA approval. Could you please provide some clarity on the current status of nesiritide in the US market? Thank you for your time and attention.
