摘要:
Described herein are treatment tip apparatuses (e.g., devices, systems, etc.) including one, or more preferably a plurality, of electrodes that are protected by an electrode partition, such as an electrode housing (which may be retractable) until pressed against the tissue for deployment of the electrodes and delivery of a therapeutic treatment. In particular, these apparatuses may include a plurality of treatment electrodes (e.g., needle electrodes) and be configured for the delivery of nanosecond pulsed electric fields.

The present disclosure describes a closely spaced array of penetrating electrodes. In some implementations, the electrodes of the array are spaced less than 50 µm apart. The present disclosure also describes methods for manufacturing the closely spaced array of penetrating electrodes. In some implementations, each row of electrode of the array is manufactured in-plane and then coupled to other rows of electrodes to form an array.

Dispositivo destinado al sector médico hospitalario para el diagnóstico, regeneración inducida en tejidos mediante electrolisis percutánea terapéutica y electro-estimulación focalizada basado en el uso de al menos una aguja bipolar que comprende en una área muy reducida de dos electrodos situados en el conductor exterior e interior de dicha aguja bipolar, limitando el tejido a tratar en la área del bisel de la aguja sin afectar al tejido sano circundante en el que se aplica a dicha aguja bipolar las señales eléctricas necesarias para diagnosticar el grado de degeneración y calcular la carga eléctrica necesaria para el tratamiento del tejido lesionado llevando un control de dicha corriente de manera que elimina las contraindicaciones que existen actualmente.
摘要:
An interface for coupling with a percutaneously implantable lead is described. The interface includes a rotation based system to engage the terminal connector of the lead. The interface includes a brake which retains the lead in the lead port through friction, but allows the lead to exit the lead port if sufficient force is applied. The interface can be coupled with the lead without removing a stylet or stiffening wire from the lead.

An EEG headpiece comprises an array of electrode pins, each electrode pin extending between a proximal end, formed by a proximal end face, and a distal end and comprising a conducting electrode and a thermoplastic material. The thermoplastic material is arranged at least around a periphery of the electrode pin or is pressable from a hollow space to the periphery. Each electrode pin is equipped for the transmission of energy, especially mechanical vibration energy, from the proximal end face to the thermoplastic material to liquefy at least portions of the thermoplastic material from a solid state to a flowable state, whereby the thermoplastic material is capable of flowing into structures of a tissue portion surrounding the periphery and of forming, after re-solidification of the thermoplastic material, an anchoring of the electrode pin in the tissue portion.

This document provides devices and methods for the treatment of heart conditions. For example, this document provides a percutaneous temporary epicardial pacemaker device and system for treating heart arrhythmia. In one implementation, a pacemaker device includes an electrode assembly including an electrode positioned at a distal end of the electrode assembly; a handle; and an adjustment mechanism whereby the electrode can be axially extended and axially retracted in relation to the handle.

Devices and systems for injecting fluids, such as anesthetics, to or near nerve tissue or other targeted anatomical location are disclosed herein. A conduit is generally configured to place the fluid delivery module in fluid communication with a needle that is configured to be inserted into the subject's anatomy. One or more medicaments (e.g., anesthetics) and/or other materials contained within containers (e.g., vials) that are secured to the injection system can be selectively delivered into an anatomy through the needle. Nerve stimulation and/or imaging technologies (e.g., ultrasound) can be used to locate a targeted anatomical location. Aspiration can be used to confirm needle location. An overlay on the imaging display can include, in addition to real-time imaging data, data and other information relating to back pressure at or near the needle tip, volumes or other amounts of fluids delivered by and remaining within the system, stimulation level and/or the like.
摘要:
A non-pharmaceutical apparatus, system and process for treating and/or detecting biological targets, such as infectious diseases, are provided in various implementations. In one implementation, a medical device, system and/or process targets biologic targets such as microorganisms, fungi, bacteria and viruses resident in an infected environment. Further various method of detecting the biological targets are also provided.
摘要:
A trial stimulation system includes a disposable trial electrical stimulator that, in some examples, is sterilized for a single use in a stimulation trial of one patient. Additionally, systems for securing a disposable trial stimulator to the body of a patient are described, which may function to improve the durability of the system during the trial period and reduce the risk of damage or malfunction to the system due to lead/electrode dislocation and/or off-label uses like showering or bathing with the trial stimulator still secured to the body
