Class, lib

All non-invasive devices intended for modifying the biological or chemical composition of blood, other body liquids or other liquids intended for infusion into the body are in Class lib, unless the treatment consists of filtration, centrifugation or exchanges of gas, heat, in which case they are in Class lla. Rule 4...

All active therapeutic devices intended to administer or exchange energy are in Class lla unless their characteristics are such that they may administer or exchange energy to or from the human body in a potentially hazardous way, taking account of the nature, the density and site of application of the energy, in which case they are in Class lib. 

Active devices intended to emit ionizing radiation and intended for diagnostic and therapeutic interventional radiology including devices which control or monitor such devices, or which directly influence their performance, are in Class lib. 

All devices intended specifically to be used for disinfecting, cleaning, rinsing or, when appropriate, hydrating contact lenses are in Class lib. 

By derogation from other rules, blood bags are in Class lib. 

STE and NSTE ACS, class I recommendation in all patients without contraindications for oral P-blockers, class I (NSTE ACS) and I la (STE ACS) for IV P-blockers, class lib recommendation for patients with moderate left ventricular failure with signs of heart failure provided they can be closely monitored. 

NSTE ACS, class lib recommendation for diltiazem for patients with AMI. 

Class II recommendations are those conditions for which there is conflicting evidence and/or a divergence of opinion about the usefulness/efficacy of a procedure or treatment. For Class lla recommendations, the weight of the evidence/opinion is in favor of usefulness/efficacy. Class lib recommendations are those for which usefulness/efficacy is less well established by evidence/opinion. 

Class lib The evidence documented only short-term benefits, or positive results were documented with lower levels of evidence. Class lib recommendations can be considered either optional or recommended by experts despite the absence of high-level supporting evidence.

AsnRS, LysRS, and AspRS, the partners of class lib aaRSs, display strong resemblances in the modular organization of their catalytic domain, but superposition reveals angular shifts of the N-terminal domain, which can reach up to 18.8°. ... 

HDAC6, a member of class lib, has received attention due to its identification as a Hsp90 deacetylase. This results in degradation of Hsp-90 associated pro-survival and pro-proliferative client proteins. Key examples include... 

The model DW4734A must be defined in one of the PSpice libraries. If you look in Appendix E on page 619, you will see the text below in the file class.lib ... 

The nominal value of pF is 200. The range of pF is 200 150. The transistor is equally likely to have a value anywhere in this range. The name of the model is QBf. The text NPN specifies the model as an NPN bipolar transistor. This model is included in class.lib. A limitation of this model is that none of the other transistor parameters have been specified. This model is almost ideal. Its limitations will become apparent when you observe that the high-frequency response does not roll off, even at frequencies beyond 1 GHz. 

The last model we will look at is a capacitor model with +80% and -20% tolerance. This model is called CAP20 80 and is included in class.lib ... 

In the library class.lib there are two jFET models called jMAX and jMIN. These models correspond to the minimum and maximum limits of the model J2n5951. The model jMAX is shown below ...
