摘要： A guidewire structure includes a medical guidewire and an overtube. The medical guidewire includes a first segment and a lengthwise-adjoining second segment. The overtube is adapted to slidably cover the first segment and to slidably expose the first segment. A minimum force required to slide the exposed first segment over patient tissue is greater than a minimum force required to slide the covered first segment over the patient tissue. A method for using a guidewire structure includes extending at least a portion of the second segment beyond a distal end of an insertion tube of an endoscope, extending at least a portion of the first segment beyond the distal end with the overtube covering the extended first segment, sliding the overtube off the extended first segment exposing the first segment, and advancing the insertion tube along the exposed and extended first segment further into a body lumen of a patient.

摘要： An electrical ablation device may generally comprise first and second electrodes coupled to an energy source operative to generate and deliver a first sequence of electrical pulses and a second sequence of electrical pulses to tissue having a necrotic threshold, wherein the first sequence of electrical pulses delivers a first energy dose that is less than the necrotic threshold to induce thermal heating in the tissue and the second sequence of electrical pulses delivers a second energy dose equal to or greater than the necrotic threshold to induce cell necrosis in the tissue by irreversible electroporation. The first sequence of electrical pulses may each be independently characterized by a first amplitude, a first pulse width, and a first frequency. The second sequence of electrical pulses may be characterized by a second amplitude, a second pulse width, and a second frequency.
