The device of the present invention comprises an intervening release liner as a common special feature, and the intervening release liner covers a part of an adhesive surface of a patch. The intervening release liner gets away from the patch, and is fixed to a patch application support (or porator tab). Due to such constitution, under a situation in use where the first part of the adhesive area of the patch adheres to a skin surface, the patch application support is slidable along the skin surface while peeling the intervening release liner from said part of the adhesive area of the patch to adhere to the skin surface.

This invention provides methods and systems for achieving high-specificity killing of targeted cells using Magneto-Electric Nano-Particles (MENPs) and functional or diagnostic imaging that detects changes at the cellular level. Embodiments comprise injecting into a patient's body manufactured MENPs that have a higher tendency to accumulate near or attach to targeted cells through one or more physical forces and/or biological mechanisms; and applying a magnetic field to the MENPs to generate an action that is sufficient to cause death of the targeted cells, and using an imaging apparatus to image or detect a specific property of the MENPs or changes in a property of the MENPs due to the coupling of the MENPs with their surrounding environment.

An irreversible electroporation and radio frequency ablation (IRE/RFA) generator incudes an IRE pulse generator, harmonic filtration circuitry, and a waveform interleaver. The IRE pulse generator is configured to generate biphasic IRE pulses. The harmonic filtration circuitry is configured to convert the IRE pulses into an RF signal. The waveform interleaver, which is configured to receive the IRE pulses and the RF signal and generate an IRE/RFA output signal by interleaving in alternation one or more of the IRE pulses with one or more periods of the RF signal.

The invention provides for a system for estimating a 3-dimensional treatment volume for a device that applies treatment energy through a plurality of electrodes defining a treatment area, the system comprising a memory, a display device, a processor coupled to the memory and the display device, and a treatment planning module stored in the memory and executable by the processor. In one embodiment, the treatment planning module is adapted to generate an estimated first 3-dimensional treatment volume for display in the display device based on the ratio of a maximum conductivity of the treatment area to a baseline conductivity of the treatment area. The invention also provides for a method for estimating 3-dimensional treatment volume, the steps of which are executable through the processor. In embodiments, the system and method are based on a numerical model which may be implemented in computer readable code which is executable through a processor.

The robot control system comprises a control console and a control unit in signal communication with the control console and the robotic tool. The surgical hub comprises a display. The surgical hub is in signal communication with the robot control system. The surgical hub is configured to detect the surgical instrument and represent the surgical instrument on the display.

Presented herein are techniques for providing tinnitus relief to recipients via an implantable arrangement. In accordance with embodiments presented herein, an implantable medical device, such as implantable tinnitus therapy device, auditory/hearing prosthesis, etc., comprises one or more implantable sensors configured to be implanted in a recipient. The one or more implantable sensors are configured to detect body noises of the recipient. The implantable medical device is configured to classify/categorize the one or more body noises and set, select, or otherwise determine a tinnitus therapy for the recipient based on the classification of the one or more body noises.

A method of delivering pulsed electrical energy to a target tissue region includes delivering a first therapeutic pulse, the delivering of the first therapeutic pulse includes delivering a first pulse for a first time period, the first pulse having a first voltage amplitude. A second pulse is delivered immediately after the first pulse for a second time period, the second pulse having a second voltage amplitude configured to electroporate the target tissue region, the second time period being less than the first time period. A third pulse is delivered without delay after the second pulse for a third time period, the third pulse having a third voltage amplitude being at least one from the group consisting of substantially the same as the first amplitude, larger than the first amplitude, and less than the first amplitude.

A “localizable” systemic gene therapy system is provided substantially increasing the transfection efficiency of the gene vectors into targeted tissue cells and substantially reducing the escape of the gene vectors from the targeted tissue volume, such as would waste the vectors, promote undesired immune reactions, and/or incur prohibitive costs for the required dose of gene-containing virus vectors. In this regard, the invention provides a means to simultaneously achieve local electroporation and gene-containing vector injection in a portion of a vascularized organ. It includes two double-balloon catheters that create contained volumes in parallel blood vessels for the introduction of vectors with reduced loss along with electrodes providing electroporation of the cells in the same location where the vectors are injected.

Apparatus is provided that includes a two-dimensional arrangement (70) of extracranial electrodes (30), configured to be placed outside and in electrical contact with a skull of a subject identified as at risk of or suffering from a disease; and a cerebrospinal fluid (CSF) electrode (32), configured to be implanted in a ventricular system of a brain of the subject. Control circuitry is configured to drive the extracranial and the CSF electrodes (30, 32) to clear a substance from brain parenchyma of the subject into at least one region of the brain selected from the group consisting of: a subarachnoid space of the brain and dural sinuses of the brain. Other embodiments are also described.

Described herein are apparatuses and methods for applying high voltage, high current, sub-microsecond (e.g., nanosecond range) pulsed output to a biological material, e.g., tissues, cells, etc., while preventing damage from load arcing. Some of the apparatuses and methods described herein may limit the load and pulsed power source current in case of load arcing significantly by using a transmission line (e.g., coaxial cable, twisted pair or parallel pair cables) between the pulsed power source and the load having a length configured to achieve this goal.
