Estimating the term…
A pulsed field delivery device for delivery of electroporation treatment to cancerous and pre-cancerous regions of the gastrointestinal tract is described. It has a first expanding body coupled non-conductively to a second expanding body wherein the non-conductive coupling allows elements of the expanding bodies to sit on opposite sides of a tissue across which pulsed electric fields are applied. An elongate shaft has a proximal end which extends exterior of the patient so that a user can advance and withdraw the device when required. The device also comprises an elongate member or sheath which can be advanced over or retracted back off of the distal end of the device providing protection during device movement. The electrodes are arranged to radially expand and to move closer together to pinch diseased tissue being treated.
An electroporation probe comprising an elongate support, the support comprising electrical conductors and being configured to extend through a lumen of a human or animal body extending in a longitudinal direction with a longitudinal axis from a proximal end to a distal end, the support supporting at least two electroporation electrodes connected to the conductors and being mounted to engage tissue in the wall of a lumen in use, and an electrode actuator.
