Nanoelectroablation control and vaccination
First Claim
1. A method of vaccinating a subject against a tumor, the method comprisingpassing multiple treatments of sub-microsecond pulsed electric fields with different parameters through tumor cells of a first subject;
- selecting, based on the multiple treatments, optimized parameters to formulate an effective sub-microsecond pulsed electric fields treatment which increases or maximizes apoptosis of the tumor cells of the first subject; and
using the formulated sub-microsecond pulsed electric fields treatment with the optimized parameters to create a vaccine with the increased or maximized apoptotic tumor cells to treat the tumor cells or other tumor cells of the first subject or a different subject with a same type of tumor cells.

Abstract
Techniques for treating a tumor and vaccinating against cancer are described. The techniques include treating the tumor by positioning electrodes over an interface between the tumor and non-tumor tissue and applying sub-microsecond pulsed electric fields. The positioning is facilitated by an imaginary contour line of a threshold value of the electric field. In an example, the imaginary contour line is overlaid over images that include the tumor such that the electrodes are properly positioned over the tumor. The techniques also include vaccinating against cancer by passing sub-microsecond pulsed electric fields through tumor cells of a subject sufficient to cause the tumor cells to express calreticulin on surface membranes. The tumor cells are extracted and introduced with the expressed calreticulin into the subject or another subject, thereby providing a vaccination.
