摘要：
#$%^&*AU2016201567A120160526.pdf#####The present invention provides methods for resecting and removing target tissue from a patient's body, such as fibroids from a uterus. The tissue is cut, captured in a probe, catheter, or other tissueremoval device, and expelled from the capture device by vaporizing a fluid, typically a liquid, adjacent to the captured tissue in order to propel the tissue from the device, typically through an extraction or other lumen present in a body or shaft of the device. Exemplary embodiments, the tissue removal device comprise a reciprocating blade, tubular cutter, or the like, where the blade may be advanced past a cutting window on the device in order to sever a tissue strip and capture the strip within an interior volume or receptacle on the device. The liquid or other expandable fluid is also present in the device, and energy is applied to the fluid in order to cause rapid expansion, e.g. vaporization, in order to propel the severed tissue strip through the extraction lumen. In this way, the dimensions of the extraction lumen can be reduced, particularly in the distal regions of the device where size is of critical importance.
