Method and apparatus for laser balloon angioplasty treatment of medical conditions

摘要: A laser balloon catheter device includes a housing containing guidewire and an inelastic balloon. The is surrounded by clear silicone sleeve. series of polyester electrically conductive flexible film strips are embedded inside the sleeve adjacent Each strip contains several vertical cavity surface-emitting lasers, each operating at 760-780 nanometer wavelengths 1-10 milliwatts power. During angioplasty procedure, inserted into affected artery across region stenosis. inflated using inflation fluid provided from external source. expands to eliminate Power simultaneously applied lasers for period 5-10 minutes encourage healing reduce occurrence restenosis.
