Tufts CTSI TranslationalDay2017: Lessons learned from the front lines

Rami Tzafriri, PhD and Michael Naimark, MS. “Lessons Learned from the Front Lines.” Summary: The Directors of Research and Innovation and Business Development presented advice and lessons learned from CBSET Inc.’s experiences on how to differentiate a new technology and navigate through a successful path to the market, and how to find the correct testing paradigm […]

TCT 2017: Stent based tissue drug and binding target protein distributions: durable versus deployable coatings

Rami Tzafriri, PhD. “Stent based tissue drug and binding target protein distributions: durable versus deployable coatings.” Summary: We developed immunofluorescence (IF) methods to track drug and target protein distribution in stented arteries, to aid the development and assessment of novel stent designs. Xience Pro (74 μg Everolimus/3.0×15 mm, durable coating) and MiStent (135 μg Sirolimus/3.0×15 mm, […]

SIB 2017: Particulate embolization from catheter coatings

Rami Tzafriri, PhD. ‘Particulate embolization from catheter coatings.’ Summary: Medical catheters permit minimally invasive external access for monitoring, imaging, sampling, local delivery of therapeutic agents, and placement of devices like endovascular stents, aneurysm coils and transcatheter valves. Catheter coatings are employed extensively as enhancers of device lubriciousness/ steerability and as platforms for local drug delivery. […]

VIVA2017: Plaxitel-Coated PTA Balloon Catheter: microcrystalline coating for improved delivery and retention

Rami Tzafriri, PhD. “Plaxitel-Coated PTA Balloon Catheter: microcrystalline coating for improved delivery and retention.” Summary: Drug coated balloons are a promising therapy for peripheral arterial disease, but differences in efficacy between devices and non-responders cannot be understood using current methods. To address this void, we developed methods for visualizing and quantifying coating distribution on arterial surfaces […]

CX 2017: Peripheral Innovation: Evaluation of a novel paclitaxel coated intravascular balloon

Peripheral Innovation: Evaluation of a novel paclitaxel coated intravascular balloon. Rami Tzafriri, PhD Summary: The presentation illustrated an innovative preclinical paradigm for evaluating and optimizing novel drug-coated balloon technologies by combining bioanalysis with imaging of the coating distribution. Presented at: CX 2017 – The Charing Cross International Symposium, April 25-28, Kensington, London, UK.

Society for Biomaterials: *BTI* From Benchtop to Clinical Trial: Examples of technology development

*BTI* From Benchtop to Clinical Trial: Examples of technology development. Rami Tzafriri, PhD Summary: Drawing on examples from renal denervation and other thought-leader debates at the conference, the presentation focused on several issues, including whether benchtop-to-clinical is the only path for new medical technologies, the roles and advantages of preclinical vs clinical trials in technology development, and […]

ICI 2016: Multiple drug coated balloon exposures increase arterial permeability and drug retention

Rami Tzafriri; Peter Markham; Brett Zani; Steve Alston; Elazer Edelman. ‘Multiple drug coated balloon exposures increase arterial permeability and drug retention.’ Presented at: Innovations in Cardiovascular Interventions (ICI), Dec 4-6, 2016, Tel Aviv, Israel. Summary: It is thought that increased dose or number of drug-coated balloon (DCB) inflations increases drug delivery and tissue retention – this […]
