Abbott Laboratories received U.S. FDA approval for its Esprit below-the-knee (BTK) everolimus-eluting resorbable scaffold system for use in chronic limb-threatening ischemia well ahead of the expected second half 2024 time frame. Esprit showed clear superiority to angioplasty in the LIFE-BTK trial presented at last year’s Transcatheter Cardiovascular Therapeutics conference and published in The New England Journal of Medicine.
