Systems, methods, and devices for treating a subject are described herein. In some embodiments, an applicator for selectively affecting a subject's subcutaneous tissue is provided. The applicator can include: a housing; a treatment cup mounted in the housing, wherein the treatment cup defines a tissue-receiving cavity and includes a temperature-controlled surface; at least one thermal device coupled to the treatment cup and configured to receive energy via a flexible connector coupled to the applicator and to cool the temperature-controlled surface; an at least one vacuum port coupled to the treatment cup and configured to provide a vacuum to draw the subject's tissue into the tissue-receiving cavity and against at least a portion of a treatment area of the temperature-controlled surface to selectively damage and/or reduce the subject's subcutaneous tissue.

Provided is an ablation device including a narrow insertion section insertable into a body, a distal end section provided at a distal end of the insertion section and having a narrow cauterizing surface that is formed in a longitudinal direction in one area in a circumferential direction and that releases energy to biological tissue, and a radiopaque marking section provided at the distal end section and substantially parallel to the cauterizing surface. The marking section has a three-dimensional shape such that projection shapes obtained when projected from different sides in a radial direction of the distal end section are different from each other.

A cooled radiofrequency ablation system including a probe assembly having a proximal region, a distal tip region, and a shaft is provided. First and second internal cooling fluid tubes extend from the proximal region and are positioned inside a cavity defined by the shaft. The distal tip region includes a conductive portion for delivering energy to a target location within tissue. The system also includes a radiofrequency generator for delivering energy to the target location and a cooling fluid reservoir and a bidirectional pump assembly for circulating a cooling fluid from the reservoir through the first internal cooling fluid tube then the second internal cooling fluid tube when the pump operates in a first direction or through the second internal cooling fluid tube then the first internal cooling fluid tube when the pump operates in a second direction to form lesions of different sizes at the target location.

Techniques for High-Frequency Irreversible Electroporation (HFIRE) using a single-pole tine-style internal device communicating with an external surface electrode are described. In an embodiment, a system for ablating tissue cells in a treatment region of a patient's body by irreversible electroporation without thermally damaging the tissue cells is described. The system includes at least one single-pole electrode probe for insertion into the treatment region, the single-pole electrode probe including one or more tines. The system further includes at least one external surface electrode for placement outside the patient's body and configured to complete a circuit with the single-pole electrode probe. The system also includes a control device for controlling HFIRE pulses to the single-pole tine-style electrode and the skin-surface electrode for the delivery of electric energy to the treatment region. Other embodiments are described and claimed.
