Problems solved by technology

During surgery, the user can alternately use the injection needle and the energy delivery device, but swapping devices can increase the duration and risk of the medical procedure
Additionally, situations may arise where it is possible to change the type of injection needle required
Also, in some cases, it may be necessary to change the type of energy delivery device required
This can further increase the duration of medical procedures and / or limit the types of procedures that can be performed

Embodiment Construction

[0030]Examples of the invention include devices and methods for: facilitating and enhancing the effectiveness, efficiency and safety of treating tissue when, for example, applying electrical energy to the tissue; and delivering fluid into and / or beneath tissue during medical procedures . For example, aspects of the invention may provide a user (e.g., physician, medical technician, or other medical service provider) with the ability to apply electrical energy or heat to tissue with a medical device having electrodes and deliver fluid to tissue with the same medical device. capabilities in and / or beneath the organization. Additionally, aspects of the invention may provide the user with the ability to deliver fluid through one or more outlets, where the fluid is diverted on its way to the outlet (e.g., delivered at an angle relative to the central longitudinal axis of the electrode), thereby Change the fluid flow path. Other aspects of the invention may allow the user to change...

Abstract

A medical device includes a shaft including a lumen configured to direct a flow of fluid through the shaft and an electrode. A proximal end of the electrode and a distal end of the shaft form a coupling configured to releasably couple the proximal end of the electrode with the distal end of the shaft. When the proximal end of the electrode is coupled to the distal end of the shaft, fluid deliveredthrough the lumen is emitted from the electrode.

Description

technical field [0001] Aspects of the invention generally relate to medical devices and related methods. In particular, aspects of the invention relate to medical devices and associated methods configured to treat tissue by delivering electrical energy to or into tissue with one or more electrodes and injecting fluid into and / or beneath tissue . Background technique [0002] Medical devices, such as endoscopes or other suitable insertion devices, used in various types of diagnostic and surgical procedures, such as endoscopy, laparoscopy, arthroscopy, gynecoscopy, thoracoscopy, cystoscopy Wait. Many of these procedures involve delivering energy to the tissue of an organ or gland to treat tumors, infections, etc. Examples of such procedures include endoscopic mucosal resection (EMR), endoscopic submucosal resection (ESR), endoscopic submucosal dissection (ESD), polypectomy, mucosal resection, and the like. In particular, such procedures may be performed by inserting an ins...
