The present invention relates to apparatus for topical application of material for cosmetic purposes (10). The apparatus for topical application of material (10) comprises measurement apparatus configured to measure a property of skin of a human or animal subject and actuating apparatus configured to change a permeability of the skin of the human or animal subject in dependence on the measured property of the skin. The apparatus for topical application of material (10) further comprises application apparatus configured to apply material for cosmetic purposes to the skin whilst substantially no iontophoretic current flows through the skin and after the permeability of the skin has been changed.

An exemplary apparatus, can include, for example, a circulating tumor cell (CTC) treatment arrangement, a pump arrangement configured to circulate a fluid through the CTC treatment arrangement, and an electric field generator electrically connected to the CTC treatment arrangement, and configured to apply an electric field to the fluid circulating through the CTC treatment arrangement. The pump arrangement can be a peristaltic pump, which can be configured to continuously circulate the fluid through the CTC treatment arrangement. According to another exemplary embodiment of the present disclosure, method, system and computer-accessible medium can be provided for killing at least one circulating tumor cell (CTC). Using such exemplary embodiment, blood can be pumped from a body of a patient to an electroporation chamber inside of a CTC treatment arrangement. An electric field can be applied to the blood located in the electroporation chamber in order to kill the CTC. The electric field-applied blood can be pumped back into the body.

A patch for a therapeutic electrical stimulation device includes a shoe connected to the first side of the patch, the shoe including a body extending in a longitudinal direction from a first end to a second end, and having first and second surfaces, the first end of the shoe defining at least two ports, and the first surface of the shoe defining a connection member. The patch also includes at least one conductor positioned in the ports of the first end of the shoe. The shoe is configured for sliding insertion into a receptacle defined by a controller so that the conductor is connected to the controller to deliver electrical current from the controller, through the conductor, and to the electrodes, and the connection member is at least partially captured by a detent defined by the controller in the receptacle to retain the shoe within the receptacle.

A wearable item is formed of conductive fibers and non-conductive fibers. Encapsulated nutrients are placed on the non-conductive fibers. A voltage is placed on the conductive lines in order to induce an electric field so that the effective absorption rate of the nutrients through the skin of a user is increased.

An improved system described herein can include an expandable member (e.g., to temporarily dilate a targeted tissue) equipped with one or more Pulsed Field Electroporation (PFE) electrodes configured to cause localized and targeted PFE output at the targeted tissue.

Example systems, apparatuses, methods, and computer program products are disclosed for electroporating cells in a tissue using a set of voltage pulses generated by capacitor charge circuitry based on a voltage supply. An example method includes continuously monitoring a set of characteristics of the voltage supply and the set of voltage pulses; generating a first set of monitor signals based on the set of characteristics; detecting a first fault condition based on the first set of monitor signals; and generating a first crowbar trigger activation signal. The example computer method further includes: detecting a second fault condition based on a second set of monitor signals generated based on the first set of monitor signals; and generating a second crowbar trigger activation signal. Subsequently, the example computer method includes electrically disconnecting the capacitor charge circuitry from electroporation electrode circuitry based on either the first or second crowbar trigger activation signal.

The disclosure is directed to a device for electroporating and delivering one or more antigens and a method of electroporating and delivering one or more antigens to cells of epidermal tissues using the device. The device comprises a housing, a plurality of electrode arrays projecting from the housing, each electrode array including at least one electrode, a pulse generator electrically coupled to the electrodes, a programmable microcontroller electrically coupled to the pulse generator, and an electrical power source coupled to the pulse generator and the microcontroller. The electrode arrays define spatially separate sites.

Nanosecond pulsed electric field (nsPEF) treatments of a tumor are adjusted based on a size and type of the tumor to stimulate an immune response against the tumor and other tumors in the subject. Calreticulin expression on tumor cells can be detected to confirm treatment. An immune response biomarker can be measured, and further nsPEF treatments can be performed if needed to stimulate or further stimulate the immune response. Cancers that have metastasized may be treated by directly treating a tumor that is most accessible. The treatment can be combined with CD47-blocking antibodies, doxorubicin, CTLA-4-blocking antibodies, and/or PD-1-blocking antibodies. Electrical characteristics of nsPEF treatments can be based on the size, type, and/or strength of tumors and/or a quantity of tumors in the subject.

A transdermal delivery system (1) configured to deliver an active agent to human or animal tissue, comprising a penetrative electrode (2) of one polarity that provides an electrical contact (3) beneath the stratum corneum (20); a surface electrode (4) of the opposite polarisation to that of the penetrative electrode (2) that provides an electrical contact to the external surface of the skin (21) on the opposite side of the stratum corneum (20) to the electrical contact (3) of the penetrative electrode (2); a dispenser (5) configured to deliver of an active agent to the external surface of the skin (21) adjacent to an electrical contact of the surface electrode (4); a method of delivering the active agent to the tissue of a human or animal body using the transdermal delivery system (1) and an electrode assembly (10) for use in preparing the transdermal delivery system (1).

Systems and methods are described for operating an electroporation system with single cell resolution. A micromanipulator assembly includes three orthogonally-positioned linear movement stages and a rotational stage to adjust the position of a tip of a micropipette. The system is configured to detect when the tip of the micropipette is placed in contact with an exterior surface of a cell based at least in part on a measured resistance from a first electrode positioned within the micropipette. In some implementations, the resistance is measured between the first electrode and a second electrode positioned at a defined distance from the tip of the micropipette and moved by the micromanipulator assembly with the micropipette. In some implementations, the control unit applies filtering and conditioning mechanisms to the measured resistance signal in order to detect contact between the tip of the pipette and the exterior surface of the cell. It also applies electroporation pulses of different shapes, durations, and frequencies.
