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.

摘要： A surgical instrument for creating an anastomosis between two organs. In various embodiments, the instrument may include a hollow outer sleeve for creating a tool-receiving passage between a natural orifice in the patient and the surgical site. The tool receiving passage may be used to operably accommodate various surgical instruments such as an endoscope, a hole-forming instrument, and suction and aeration tubes for assisting in the formation of the anastomosis. The hollow outer sleeve may further be used to position a hollow anastomosis sleeve segment within two aligned holes in the organs. The anastomosis sleeve segment supports an inflatable distal receptacle that is inflated within one of the organs and a proximal inflatable receptacle that is inflated in the other organ to retain the anastomosis sleeve segment in position. Thereafter, the hollow outer sleeve is withdrawn from the patient leaving the hollow anastomosis sleeve segment in position between the two organs.

摘要： A guidewire structure includes a medical guidewire and an attached guidewire anchor having collapsed and expanded states. The anchor includes struts and defines in the expanded state an open structure. Another guidewire structure includes a medical guidewire, an attached guidewire anchor having collapsed and expanded states, and an overtube. The anchor is resiliently flexible and is resiliently biased to the expanded state. The overtube is adapted to slide over the medical guidewire, to slidably cover and compress the anchor, and to slidably expose the anchor. Another guidewire structure includes a medical guidewire, a guidewire anchor, and a hollow tube having a distal end attached proximate the proximal end of the guidewire anchor. The medical guidewire is positioned within the hollow tube and within the guidewire anchor and is attached proximate the distal end of the anchor. The anchor is flexible and has collapsed and expanded states.

摘要： A medical device for use with an endoscope is provided. The medical device can include a tube with a first channel for receiving the endoscope. A transparent segment can extend from the distal end of the tube, and the transparent segment can have a first outer diameter sized for providing dilation of a portion of a body lumen. The medical device can also include a tapered tip attached to the distal end of the transparent segment that narrows from the first outer diameter to a distal terminating end. The endoscope is used to view the body lumen through the medical device while in use to dilate a stricture under direct visualization.
