Methods and apparatus for creating particle derivatives of HDL with reduced lipid content
First Claim
1. A selectively delipidated biological fluid comprising a particle derivative of an HDL particle and a substantially unmodified LDL particle as compared to an LDL particle,wherein the selectively delipidated biological fluid is formed by an extracorporeal selective delipidation process comprising the step of exposing a biological fluid comprising the HDL particle and the LDL particle to a lipid removing agent,wherein the particle derivative of the HDL particle comprises a lipid bilayer comprising phospholipids and a protein shell comprising apolipoprotein A-1, apolipoprotein A-2, and at least one of apolipoprotein C-III, apolipoprotein D or apolipoprotein E, andwherein a cholesterol content of the HDL particle derivative is lower than a cholesterol content of the HDL particle.

Abstract
The present invention is directed to systems, apparatus and methods for creating derivatives of at least one form of HDL without substantially affecting LDL. These derivatives of HDL are particles with reduced lipid content, particularly reduced cholesterol content. These particles have the capacity to bind cholesterol and are administered to a patient to enhance cellular cholesterol efflux and reduce cholesterol levels in cells, tissues, organs, and blood vessels. The present method is useful for treating atherogenic vascular disease and may be combined with other therapies such as statins, inhibitors of cholesterol absorption, niacin, anti-inflammatories, exercise and dietary restriction.
