TIFR Zero-Pressure balloon program crosses a milestone [PDF]

arXiv, 2021
High altitude scientific balloons offer unique opportunities to carry scientific payloads to stratospheric altitudes at a cost several orders of magnitude lower than corresponding satellite missions. Balloon-borne payloads are easy to implement allowing quick experiment turn-around times and inexpensive reflights can be conducted as payload is most of ...

INtravaScular OptIcal Frequency Domain ImaGing EvaluaTion of the Femoropopliteal Lesion With JETSTREAM Atherectomy (INSIGHT JETSTREAM)

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background There have been no prior reports of detailed evaluations using intravascular imaging during Jetstream treatment. Aims This study, therefore, aimed to investigate the effects of calcification characteristics and wire bias on lumen gain in Jetstream atherectomy using optical frequency domain imaging (OFDI). Methods This study enrolled

Enhanced Drug Effect With Cutting Balloon Followed by Drug Coated Balloon in a Rabbit Model

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Drug‐coated balloon (DCB) are effective treatment options for patients with coronary artery disease and using of scoring or cutting balloon before the DCB usage were recommended. However, the effectiveness of lesion preparation with cutting balloons (CB) followed by DCB (CB + DCB) has not been evaluated before.
