Method of applying acoustic energy effective to alter transport or cell viability

A method for reversibly, or irreversibly, altering the permeability of cells, tissues or other biological barriers, to molecules to be transported into or through these materials, through the application of acoustic energy, is enhanced by applying the ultrasound in combination with devices for monitoring and / or implementing feedback controls. The acoustic energy is applied directly or indirectly to the cells or tissue whose permeability is to be altered, at a frequency and intensity appropriate to alter the permeability to achieve the desired effect, such as the transport of endogenous or exogenous molecules and / or fluid, for drug delivery, measurement of analyte, removal of fluid, alteration of cell or tissue viability or alteration of structure of materials such as kidney or gall bladder stones. In the preferred embodiment, the method includes measuring the strength of the acoustic field applied to the cell or tissue at the applied frequency or other frequencies, and using the acoustic measurement to modify continued or subsequent application of acoustic energy to the cell or tissue. In another preferred embodiment, the method further includes simultaneously, previously, or subsequently exposing the cell or tissue to the chemical or biological agent to be transported into or across the cell or tissue. In another preferred application, the method includes removing biological fluid or molecules from the cells or tissue simultaneously, previously or subsequently to the application of acoustic energy and, optionally, assaying the biological fluid or molecules.

Synchronizing Tumor Cells to the G2/M Phase Using TTFields Combined with Taxane or Other Anti-Microtubule Agents

Cancer cells can be synchronized to the G2 / M phase by delivering an anti-microtubule agent (e.g., paclitaxel or another taxane) to the cancer cells, and applying an alternating electric field with a frequency between 100 and 500 kHz to the cancer cells, wherein at least a portion of the applying step is performed simultaneously with at least a portion of the delivering step. This synchronization can be taken advantage of by treating the cancer cells with radiation therapy after the combined action of the delivering step and the applying step has increased a proportion of cancer cells that are in the G2 / M phase. The optimal frequency and field strength will depend on the particular type of cancer cell being treated. For certain cancers, this frequency will be between 125 and 250 kHz (e.g., 200 kHz) and the field strength will be at least 1 V / cm.

Presbyopia treatment by lens alteration

This invention effects a change in the accommodation of the human lens affected by presbyopia through the use of various reducing agents that change accommodative abilities of the human lens, and / or by applying energy to affect a change in the accommodative abilities of the human lens. This invention both prevents the onset of presbyopia as well as treats it. By breaking and / or preventing the formation of bonds that adhere lens fibers together causing hardening of the lens, the present invention increases the elasticity and distensibility of the lens and / or lens capsule.
