US Patent:

20100030211, Feb 4, 2010

Filed:

Jun 24, 2009

Appl. No.:

12/491151

Inventors:

Rafael Davalos - Blacksburg VA, US
Paulo A. Garcia - Christianburg VA, US
John H. Rossmeisl - Blacksburg VA, US
John L. Robertson - Floyd VA, US
Robert E. Neal - Richmond VA, US

International Classification:

A61B 18/18
A61N 1/05

US Classification:

606 41, 607 72

Abstract:

The present invention provides methods, devices, and systems for in vivo treatment of cell proliferative disorders. The invention can be used to treat solid tumors, such as brain tumors. The methods rely on non-thermal irreversible electroporation (IRE) to cause cell death in treated tumors.

International Classification:

A61B 18/14
A61M 5/00

US Classification:

604 20, 606 41

Abstract:

The present invention relates to the field of medical treatment of diseases and disorders, as well as the field of biomedical engineering. Embodiments of the invention relate to the delivery of Irreversible Electroporation (IRE) through the vasculature of organs to treat tumors embedded deep within the tissue or organ, or to decellularize organs to produce a scaffold from existing animal tissue with the existing vasculature intact. In particular, methods of administering non-thermal irreversible electroporation (IRE) in vivo are provided for the treatment of tumors located in vascularized tissues and organs. Embodiments of the invention further provide scaffolds and tissues from natural sources created using IRE ex vivo to remove cellular debris, maximize recellularization potential, and minimize foreign body immune response. The engineered tissues can be used in methods of treating subjects, such as those in need of tissue replacement or augmentation.
