Title:
ELECTRODES FOR ELECTROPORATION
Document Type and Number:
WIPO Patent Application WO/2017/145689
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a technique whereby it is possible to stably improve the efficiency of introduction of a foreign material, and perform in vivo electroporation by a simple and quick operation regardless of the operator's skill. The present invention pertains to an electrode for electroporation having a plurality of electrode needles. The electrode for electroporation is characterized in that: the electrode has a structure comprising first polarity electrode needles, an electrode needle holding part, and a syringe holding part; the electrode is configured so that two or more first polarity electrode needles protrude from the bottom surface of a lower structure of an outer frame support of the electrode needle holding part towards an object to be electroporated; the lower structure of the outer frame support has, on the bottom surface thereof, a syringe needle insertion/retrieval hole which communicates with the syringe holding part; the syringe holding part is present on the reverse side of the electrode needle holding part from the side facing the object to be electroporated; and the syringe holding part is configured to have a syringe needle insertion/retrieval path having a second polarity conductive part on at least part thereof.
