Abstract: Techniques for assessing a physiological profile of a patient include advancing a catheter shaft of a bifurcated renal catheter system into an aorta of the patient, deploying branches of the bifurcated renal catheter system into the renal arteries of the patient, detecting a renal arterial physiological parameter with a sensing mechanism, and assessing the physiological profile of the patient based on the physiological parameter. Related techniques include modifying or initiating pharmacological or surgical treatments for the patient based on the assessment.

Abstract: A Braille writing instrument has a housing which has a first end and a second end, extending in a first direction. Six plungers are positioned near the first end, arranged in a first column of three plungers and a second column of three plungers. The first and second columns are adjacent to one another to define three rows of plungers with each row having two plungers. Each plunger is movable in the first direction between a stored position and a write position. The instrument further has six styluses which are positioned near the second end, and are arranged in a first column of three styluses and a second column of three styluses. The first and second columns of styluses are adjacent to one another to define three rows of styluses with each row having two styluses. Each stylus is movable in the first direction between a retracted position and an extended position.
