Sterilizing procedures for heart-lung machines

Sterilizing Procedures for Heart-lung Machines.

Types of heart-lung machines used in extra-corporeal circulation.

IT is to extra-corporeal circulation that cardiac surgery owes its present momentum. Without this system of circulating blood outside the body through a variety of pumps and oxygenating devices, it is fair to say that no adequate access to the interior of the heart could have been obtained. Correction of congenital defects within the heart demands that the interior of its cavities be available ...

A method of sterilizing and preserving fresh allograft heart valves.

The present study was undertaken to find an antibiotic mixture which would rapidly and completely sterilize a heavily contaminated allograft heart valve without reducing its viability. Two different antibiotic combinations were used; formula A was used for 66 valves and formula B for 60 valves. Viability of the valves was assessed by autoradiography and tissue culture, and was found to be simil...

Super liquid-repellent gas membranes for carbon dioxide capture and heart–lung machines

In a gas membrane, gas is transferred between a liquid and a gas through a microporous membrane. The main challenge is to achieve a high gas transfer while preventing wetting and clogging. With respect to the oxygenation of blood, haemocompatibility is also required. Here we coat macroporous meshes with a superamphiphobic-or liquid repellent-layer to meet this challenge. The superamphiphobic la...
