Regulatory Approval Challenges: Envveno may face significant delays or outright failure in obtaining and maintaining necessary regulatory clearances and approvals from authorities such as the FDA, which could prevent or delay product commercialization.

Clinical Trial Outcomes Uncertainty: Unfavorable or inconclusive results from clinical trials, or the inability to complete trials within anticipated timelines or budgets, could severely impact product development and market readiness.

Market Adoption and Competitive Landscape Risks: Envveno's products may not achieve widespread acceptance among healthcare providers and patients, or could face intense competition from established medical device companies with greater resources and market presence.
