Abstract: Devices, systems and methods are provided for delivering molecules, particularly small molecules and/or macromolecules, to cells within the body, particularly to target cells which directly therapeutically benefit from the functionality of the molecules. Example molecules include DNA plasmids, RNAs (e.g. messenger RNA (mRNA), small interfering RNA (siRNA), micro RNA), oligonucleotides, antisense oligonucleotides (ASO), proteins and/or materials which invoke genetic or epigenetic changes in the cellular behavior, to name a few. In such instances, the molecules are driven into the target cells with the use of pulsed electric fields (PEFs) which deliver the molecules through the cell wall of the target cells so that the desired genes are able to carry out the desired effect within the cells. Thus, the molecules are to be delivered to the desired location within the body at a desired time and in a desired concentration relative to the delivery of the pulsed electric fields for optimal outcomes.

Abstract: Devices, systems and methods are provided for treating conditions of the reproductive tract. A number of conditions can afflict the lining and cell layers deeper within the anatomical structures. For example, cervical intraepithelial neoplasia (CIN), also known as cervical dysplasia, is a condition involving abnormal growth of cells on the surface of the cervix that could potentially lead to cervical cancer in situ (CIS). Other conditions include human papillomavirus (HPV)-related cervical disease, various endometrial diseases, acute and chronic cervicitis, and various infections (e.g. trichomoniasis) to name a few. In some embodiments, treatments eliminate diseased, damaged, abnormal or otherwise undesired cells leaving the tissue framework intact. This allows the tissue to regenerate in a normal fashion, avoiding the formation of scar tissue.

Abstract: Devices, systems and methods are provided for treating conditions of the heart, particularly the occurrence of arrhythmias. The devices, systems and methods deliver therapeutic energy to portions the heart to provide tissue modification, such as to the entrances to the pulmonary veins in the treatment of atrial fibrillation. Generally, the tissue modification systems include a specialized catheter, a high voltage waveform generator and at least one distinct energy delivery algorithm. Other embodiments include conventional ablation catheters and system components to enable use with a high voltage waveform generator. Example catheter designs include a variety of delivery types including focal delivery, “one-shot” delivery and various possible combinations. In some embodiments, energy is delivered in a monopolar fashion. However, it may be appreciated that a variety of other embodiments are also provided.
