Denervation of the distal renal arterial branches vs. conventional main renal artery treatment: a randomized controlled trial for treatment of resistant hypertension.

Background: Effective treatment of uncontrolled hypertension using catheter-based percutaneous renal denervation may depend strongly on the anatomic strategy applied when delivering therapy. We hypothesized that concentering renal denervation treatment in the distal region of the artery would improve clinical response.

Methods And Results: We conducted a single-center, double-blind, randomized, controlled, and parallel group study (ClinicalTrials.

Widely tunable polarization maintaining photonic crystal fiber based parametric wavelength conversion.

We report a near-visible parametric wavelength converter comprising a polarization-maintaining photonic crystal fiber (PM-PCF) pumped by a highly versatile diode-seeded master-oscillator power amplifier system based around 1.06 μm. The device is broadly tunable in wavelength (0.

Picosecond bismuth-doped fiber MOPFA for frequency conversion.

We report the development of a bismuth-doped fiber master oscillator power fiber amplifier system. The system operates at 1177 nm, producing 28 ps pulses at 9.11 MHz repetition rate, with an output power of 150 mW and a peak pulse power of 580 W.
