MedTech Monday: Philips bids on ultrasound-guided gene therapy

August 10, 2009 by MassDevice

Philips bids on ultrasound-guided gene therapy; MED-EL's Vibrant Soundbridge middle ear implant gets EU OK; nanoparticles traverse blood-brain barrier to help improve MRI visualization; microchip system can perform hundreds of parallel chemical reactions; and the FDA OKs Peak Surgical's PlasmaBlade for tonsil and adenoid tissue removal.

Philips bids on ultrasound-guided gene therapy: Delivering DNA sequences to cells for gene therapy is already being investigated, with the current approaches relying on viruses and smart nanoparticles as vectors for gene transfer. But Philips and GlyGenix Therapeutics, out of Woodbridge, Conn., plan on taking another approach, hoping that the large molecules can be pushed to their destination using ultrasound. Specifically, the pre-clinical trials will study the technology, known as ultrasound-mediated plasmid DNA (pDNA) delivery, on Glycogen Storage Disease Type 1a (GSD-1a) that exhibits a defective G6Pase gene.
