Development of ultra-thin polyethylene balloons for high altitude research upto mesosphere [PDF]
arXiv, 2014 Ever since its inception four decades back, Balloon Facility of Tata Institute of Fundamental Research (TIFR), Hyderabad has been functioning with the needs of its user scientists at its focus. During the early nineties, when the X-ray astronomy group at TIFR expressed the need for balloons capable of carrying the X-ray telescopes to altitudes up to 42

Endovascular balloon angioplasty versus stenting in patients with Takayasu arteritis
Medicine, 2017 Background: Symptomatic or significant vascular lesions of Takayasu arteritis (TA) need interventions. Although percutaneous transluminal angioplasty with balloon is a less invasive and safe method, stent implantation in TA can be an alternative option ...

SABAT: the "Sapienza" Balloon Trajectory Simulation Code [PDF]
arXiv, 2018 We present SABAT ("Sapienza" Balloon Trajectory Simulation Code), a Fortran software for the simulation of zero-pressure scientific balloon trajectories at stratospheric altitudes. Particular attention is made to the correct reproduction of the balloon ascending phase to the floating altitude.

Interventional Neuroradiology, 2017 Balloon angioplasty is often performed for symptomatic vasospasm following aneurysmal subarachnoid hemorrhage. Angioplasty of the anterior cerebral artery (ACA), however, is perceived to be a challenging endeavor and not routinely performed due to ...

Balloon Angioplasty for Arteriovenous Graft Stenosis
Journal of Endovascular Therapy, 2001 Purpose: To retrospectively review the long-term outcome as well as the cost effectiveness of thrombolytic therapy and balloon angioplasty (TBA) versus surgical thrombectomy and balloon angioplasty (SBA) in the treatment of prosthetic dialysis access grafts.

Circulation, 2015 Background— Drug-coated balloons (DCBs) have shown promise in improving the outcomes for patients with peripheral artery disease. We compared a paclitaxel-coated balloon with percutaneous transluminal angioplasty (PTA) for the treatment of symptomatic ...

International Journal for Numerical Methods in Biomedical Engineering, 2013 Today, the majority of coronary stents are balloon‐expandable and are deployed using a balloon‐tipped catheter. To improve deliverability, the membrane of the angioplasty balloon is typically folded about the catheter in a pleated configuration. As such,

Steam balloon concept for lifting rockets to launch altitude [PDF]
arXiv, 2018 Launching orbital and suborbital rockets from a high altitude is beneficial because of e.g. nozzle optimisation and reduced drag. Aeroplanes and gas balloons have been used for the purpose. Here we present a concept where a balloon is filled with pure water vapour on ground so that it rises to the launch altitude.

Existence theorems for thin inflated wrinkled membranes subjected to a hydrostatic pressure [PDF]
arXiv, 2006 In this paper, we establish rigorous existence theorems for a mathematical model of a thin inflated wrinkled membrane that is subjected to a shape dependent hydrostatic pressure load. We are motivated by the problem of determining the equilibrium shape of a strained high altitude large scientific balloon.

Frontiers in Cardiovascular Medicine, 2015 In chronic thromboembolic pulmonary hypertension (CTEPH), stenoses or obstructions of the pulmonary arteries due to organized thrombi can cause an elevation in pulmonary artery resistance, which in turn can result in pulmonary hypertension.
