2. Off-pump coronary artery bypass - Wikipedia

   en.wikipedia.org/.../Off-pump_coronary_artery_bypass

   Off-pump coronary artery bypass (OPCAB), or beating-heart surgery, is a form of coronary artery bypass graft (CABG) surgery performed without cardiopulmonary bypass (heart-lung machine) as a treatment for coronary heart disease. It was primarily developed in the early 1990s by Dr. Amano Atsushi.

   The first minimally invasive heart cardiac surgery was performed in the United States on January 21, 2005, at The Heart Institute at Staten Island University Hospital in Staten Island, New York by a team led by Dr. Joseph T. McGinn. This technique is an off-pump coronary artery bypass surgery.

4. Water softening - Wikipedia

   Brine draw: Water is directed through a jet pump, which pulls salt water from the brine tank, before the water and brine pass through the resin bed in the normal direction, if co-current, or in the reverse direction, if counter-current. [12] The output of this typically thirty-minute process is discarded through the drain hose.

   Water to be filtered is then applied to the filter surface until the filter clogs and the backwash cycle needs to be repeated. [3]: 264–8 [4]: 10.53–10.58 [5]: 937–9 [6]: 8.11–8.18 [7]: 353–6 Some water treatment filters use surface wash systems that break up the heavily clogged, granular media surface layer.

6. Minimally invasive direct coronary artery bypass surgery

   en.wikipedia.org/wiki/Minimally_invasive_direct...

   Minimally invasive direct coronary artery bypass (MIDCAB) is a surgical treatment for coronary heart disease that is a less invasive method of coronary artery bypass surgery (CABG). [1] MIDCAB gains surgical access to the heart with a smaller incision than other types of CABG.

   Cognitive impairment has been reported in up to 80% cases after CABG at discharge and lasts for a year in up to 40% of cases. The cause remains unclear; CPB is an unlikely cause because even in CABG patients without CPB, as in off-pump CABG, and PCI patients, the incidence is the same. [38] [39]
