Drug information is sourced from FDA, DailyMed, and other government databases. Adverse event data from FAERS does not establish causation. Always consult a healthcare professional for medical decisions.

235 active job openings with heavy investment in Engineering (100 roles) and Commercial (66 roles) signal active growth and opportunity for advancement.

Portfolio spans high-impact, life-saving devices (LifeVest, AutoPulse, Proteus Cooling System) with direct clinical relevance and meaningful patient outcomes.

Watch Out For

Recent FDA warning letter (June 2026) regarding quality and CGMP violations raises immediate concerns about operational compliance and regulatory standing.
Permanent facility closure in Palm Springs, CA affecting 96 employees (October 2025) signals ongoing restructuring and potential headcount volatility.
Minimal early-stage pipeline momentum: only 1 Phase 2 program active, 20 total trials, and limited published research (5 publications) suggest innovation output lagging relative to R&D headcount.

Quality and reporting processes

Permanent closure of Palm Springs facility affecting 96 employees in October 2025; recent FDA warning letter (June 2026) may trigger additional restructuring.

Dual regulatory and operational headwinds (FDA warning + recent facility closure) pose immediate risk to job security and organizational morale—monitor remediation progress closely.
