摘要： The invention provides endoluminal coil delivery systems and methods for positioning a coil within a body lumen. In particular, the device uses a mechanical latch in the form of jaws to positively engage the coil during positioning. The coil may be restrained in a straight configuration from within the coil, using an internal coilwire, or from outside using a catheter. Thus, the mechanism for releasing the coil to form its relaxed convoluted shape is separate from the mechanism for disengaging the coil from the delivery system. The use of an internal core wire allows a coil having a helical outer surface to be torqued against a fallopian tube or other body lumen wall, thereby firmly anchoring the coil in the target position prior to disengaging the delivery system.

摘要： The invention provides intrafallopian devices and non-surgical methods for their placement to prevent conception. The efficacy of the device is enhanced by forming the structure at least in part from copper or copper alloy. The device is anchored within the fallopian tube by a lumen-traversing region of the resilient structure which has helical outer surface, together with a portion of the resilient structure which is biased to form a bent secondary shape, the secondary shape having a larger cross-section than the fallopian tube. The resilient structure is restrained in a straight configuration and transcervically inserted within the fallopian tube, where it is released. Optionally, permanent sterilization s effected by passing a current through there resilient structure to the tubal walls.

摘要： A method and apparatus are provided for imaging a narrow body lumen, the method comprising maintaining separation between a distal end of an optical viewing scope and a lumen wall with a spacing structure which extends distally from the distal end of an access catheter. Optional spacing structures include distal cages and a guidewire which is fixed to and extends distally from the access catheter body. The invention is beneficial during either retrograde imaging of the fallopian tube, and also allows antigrade imaging and advancing the access catheter and scope under the direction of the image provided, as it prevents the tubal wall from coming into such close proximity to a falloposcope as to produce “white-out” on the imaging monitor.
